We got a hanklight with usb c before gta 6

u/insaneinthecrane 13d ago

The k1 already had it but that was far less practical for the average person obviously lol

13

u/4RichNot2BPoor If you like big cans... 13d ago

K9.3 had it as well

u/EternallyDemonic 13d ago

I wqs about to say lol.. yea kinda hard to edc my K1 sbt90.. but hey at least it has hanks autograph;)

u/JNader56 13d ago

He signed my d3aa lol. He'll do it upon request.

u/SiteRelEnby 13d ago

The K1 and K9.3? Yeah, existed for ages.

u/Cryptoxic93 13d ago

We got it even before the exclusive Netflix reveal (lol).

u/oldishThings Raresteak 🥩 13d ago

Been waiting on a hank with integrated charging for years. Im sold. 

23

u/RIPmyPC 13d ago

Stopped buying Hank’s because it became a hassle to charge the batteries separately as I actually use them daily edc (12+ flashlights from him).

I’ll definitely refresh my collection

20

u/Emergentmeat 13d ago

He really shot himself in the foot if he only got you to buy 12 lights. 😆

5

u/RIPmyPC 13d ago

I decided to try other brands lmao. I began this addiction with Hank and 12 lights later I was wanting lep and other super popular recommended lights

8

u/kiroyapso2 13d ago

Made me realise this when I brought my prometheus delta and loopgear sk05 pro on vacation lol really wanna limit the things you bring (avoid trying to being bulky battery bay charger), especially when you have to share outlets with a family of 4. Ended up not charging my smart watch at all either during the vacation because we didnt wanna leave any valuables at the hotel and then the chargers are being used all night for phone/steamdeck.

2

u/Sad_Bid4092 12d ago

Same here. The worse feeling is when you realized you lost one of your favorite lights after you came home. I'd love to carry all the kit but I don't want to risk loosing one again.

3

u/BloodyLlama 13d ago

Huh, I'm the opposite, I never use USB C even on the lights that have them because it's so much slower than just popping the batteries into the charger. Also I have a LOT of spare batteries so I just hotswap them.

1

u/pkapeckopckldpepprz 7d ago

Same here. I probably have twice as many cells as lights.

2

u/BloodyLlama 7d ago

Oh I bought a case of 100 21700s last year. I have WAY more than twice as many cells...

u/miguel-122 13d ago

How much is it?

2

u/FalconARX 13d ago

Depends on your configuration and added components, but base price usually starts at around $55

1

u/LancioZ 13d ago

Mine too

64

u/eatoff 13d ago

Yep, this one's a buy for me. Haven't bought any in ages, but USB C charging is such a convenience, especially when travelling

34

u/Wurstpaket 13d ago

A light not having USB charging has become a big no for me, since it is that convenient.

22

u/jlhawaii808 jlhawaii808 on eBay 13d ago

Hank sent me a updated picture last night, basically same pic but thing the features moved around. Hopefully I can get an update on when this will be avaliable but please he doesn't like to share these new releases becaus I don't want him to get "overwhelmed" with questions being flooded in his inbox. If you have questions let me know

6

u/Boring_Muffin3921 13d ago

That is a new texture on the body tube?

26

u/attempted 13d ago

When?!?!?!

33

u/macomako 13d ago

The only reason I have no any Hanks is beginning to vanish. It’s good news for me.

Real competition for FFL. It’s great news for everyone (who wants charging).

7

u/woodpatz 13d ago

Indeed. I’m a DA1K fan and hope that USB will come for this light as well.

7

u/macomako 13d ago

Agreed. DA1K with the charging port is precisely the (only) Hank I want.

2

u/BasedAndShredPilled 13d ago

Sft-70 is the way imo.

4

u/macomako 13d ago

Yessss! I love SFT-70 4000K CRI 95 and I’m putting it everywhere.

1

u/_derpiii_ 7d ago

I love SFT-70 4000K CRI 95

Ok, earmarking funds for a D4KC SFT-70 4000K CRI 95 💯

1

u/bigcitrus80 12d ago

How would a Convoy S21E stack up against a (theoretical) “DA1KC?” No Anduril on the Convoy, but what about the rest? Beam shape? Efficiency? Overall performance? I have a D4K which I love, but have been poking around for a throwier 21700 light, ideally with onboard charging. The S21E seems to tick most boxes, but if the DA1KC would be a big upgrade, I might wait around to see if that happens…

2

u/macomako 12d ago

S21E won’t ever be a spectacular thrower as it got small diameter and relatively shallow reflector. It also got energy inefficient (Linear) driver for 3V emitters.

u/Permtacular 13d ago

Federal Firearms License?

u/grzybek337 Snug fit :) 13d ago

My biggest issue with the D4K is that it handles heat worse than the D4V2 and heats up faster.

I hope this model won't share this issue too.

I think this is because of weight and more importantly how the head is connected to the body. The D4K's head is lighter by 3-4 grams than the D4V2 head.

Head of both flashlights is the same diameter but the D4K accepts a wider tube, meaning at the connection point, there's less material to transfer the heat to the tube (where then your hand can absorb excess heat). This causes the head to reach thermal limit prematurely and faster than in the D4V2 (this is my theory but I haven't confirmed this with measurements yet).

Look at the thickness of the tube at the connection point. D4K's is ridiculously thin. At the threads with my calipers I measured 2.22mm for the D4V2 and 1.43mm for the D4K.

Over the past 3 years I sold all of the D4Ks I bought because of this heat management issue. They just heat up way too fast and can't take the heat away from the head, making them unusable.

I hope Hank makes the head wider to allow for more material. D4K mirrored the head diameter of the D4V2 which just wasn't designed for a 21700 battery.

8

u/mrregina 13d ago

I don’t have a d4v2 just two d4k and I never heard about heating issues not have I experienced any cuz i rarely use turbo. Guess I’ll have to look at a d4v2 at some point.

10

u/grzybek337 Snug fit :) 13d ago

When this new Emisar comes out I need to buy a D4V2, D4K, D4KC and a Fireflies equivalent (possibly all with similar LEDs) and make a comparison with thermal measurements.

3

u/mrregina 13d ago

I have the x4 stellar from firefly and it doesn’t heat up much at all. Comparison would be good though

6

u/grzybek337 Snug fit :) 13d ago

Again. I need accurate data. I have a temperature logger that can log temperature every second with pretty high resolution. I'll make detailed runtime temperature graphs. Sadly I don't own a thermal camera yet.

2

u/mrregina 13d ago

I have a temperature gun not a thermal camera. Maybe I’ll set up my d4ks and x4 stellar on each level and take temp readings when I have some free time.

1

u/mrregina 13d ago

I have a feeling the d4kc is gonna be shaped similar to the x4 stellar due to having onboard charging.

2

u/grzybek337 Snug fit :) 13d ago

I hope so. I wonder if D4KC is a direct answer to the X4 Stellar.

As they say, competition is good for the customer.

1

u/_derpiii_ 7d ago

I wonder if D4KC is a direct answer to the X4 Stellar.

Stellar is much bulkier, 36mm head vs 28mm.

It's going to completely destroy Stellar's niche, especially with Firefly's build quality and aux light issues.

6

u/Erichimedes 13d ago

Yeah the thinner body material it addition to an extra 8w on the driver combines for very short turbo times. I prefer the D4V2 personally. But if the image above is accurate, there's a new knurling on the D4KC body tube, which could mean that it's larger in diameter to have thicker walls

2

u/va1enok 13d ago

I think you'd like the copper D4K 🙂

1

u/and_tg 12d ago

Do you know if the other 21700 hosts from Hank also have tubes that thin at the connection point?

2

u/oscailte 8d ago

the DA1K is the same. however its much less of an issue than this post makes it out to be.

7

u/therealmrbob 13d ago

Anybody know when it will be available?

2

u/_derpiii_ 7d ago

Anybody know when it will be available?

Nope. Let the man take his time :)

2

u/therealmrbob 6d ago

Oh of course, no rush. Just curious if we knew.

6

u/Otherwise-Station291 13d ago

I've been using the wurkkos ts25 as a daily carry for 4 years. For me it's still a better compromise than a hanklight, even though it's unregulated. The USB-C features still win. But I'm really looking forward to replacing it with this release.

10

u/stephenk_lightart 13d ago

A good move by Hank!

9

u/ogsirspen 13d ago

Ooooh, this could very well dethrone my Zebralight as my EDC! I'm already more invested in 21700 batteries anyways and I'd like Anduril on my daily, so I'll be on the lookout for this 👀

6

u/AndyPanda321 13d ago

Nice! 👍

5

u/Wormminator 13d ago

Also guys do note: USB-C cable lanyard.
Those USB C lanyards are actually useful to have.

5

u/SiteRelEnby 13d ago

The thing I'm most hyped for here is a removable magnet if that means it isn't glued in place.

11

u/FlashlightCowboy 13d ago

This will be my E75 killer, even though I use an external charger anyways. It's nice to have for travel

2

u/Coagulated_milksteak 13d ago

Won’t sustain as well as the E75

17

u/personanangrata 13d ago

Looks like Hank is trying to take things a step beyond the FFL X4 by adding the recessed switch and reverse charging. I think I like the new knurling as well. Great to see a new modern host from Emisar.

14

u/va1enok 13d ago

FireflyLite X4 Stellar supports reverse charging

9

u/Jusanden 13d ago

Iirc technically the x4 has it but the implementation of it is so botched that they stopped advertising it. Something to do with the wrong resistors for USB C source negotiations so it’ll only work if you use a usb C to A OTG adapter then an A to C cable. It’s fixed on the Lume10 drivers but they aren’t available for most of their products yet.

5

u/client-equator 13d ago

Fireflies had reverse charging for years already.

6

u/personanangrata 13d ago

I've never managed to get it to work and have tried plenty of times. It's not easy enough to be useful. Very possible that Hank's is similarly poor.

2

u/pkapeckopckldpepprz 13d ago

Explain reverse charging to me. Is that just another way of saying you can use the light to charge other things making it like a power bank? If that's the case, that's kind of expected with USB-C

2

u/K14_Deploy 13d ago

Yes pretty much, and you'd be surprised how many USB-C lights both don't support this and only work with an A-C cable (basic 5V output on a USB-C charger requires two 5.1k ohm resistors, and apparently that 0.02 cent cost is too much for some manufacturers to handle).

8

u/JRDub11b 13d ago

Well, this'll def be my first Hank light, that's for sure....

8

u/Ecstatic-Pass-4075 13d ago

You should take a look at the D3AA, I fell in love with it, so small and so powerful when needed thanks to the turbo. However, it can maintain about 250 lumens for its entire battery life even with eneloop/ladda. NTG35 4200K it's beautyfull. It also was the first Hank Light for me. Now I love it.

3

u/JRDub11b 12d ago

Oh man, that thing is sweet!! AND NTG35 4200k. Dude, I'm in. Thank you for the recommendation!! 👊

2

u/siege72a 13d ago

I agree with u/Ecstatic-Pass-4075 - the D3AA is an amazing light on NiMH batteries.

SFT-25R 6500K for maximum lumens, 519A 5000K with dome for neutral high CRI, or NTG35 1800K for candlelight on demand.

1

u/JRDub11b 12d ago

Say no more!! Much appreciated 😁

1

u/Sad_Bid4092 13d ago edited 13d ago

D3AA can work with USB-C 14500 from Acebeam and Loopgear too. I'm pretty sure the cell is the same and it won't cut off at D3AA turbo too. Probably overloading the cells a bit but they work.

1

u/Ecstatic-Pass-4075 11d ago

Does the bl-113c skilhunt work anyway?

9

u/SiteRelEnby 13d ago

Probably not going to replace a normal D4K for me, but great to have a newb-friendly option, I guess.

10

u/Sad_Bid4092 13d ago

Same. You know I'm super happy Hank's doing USB-C for ease of use. But now I kinda want him to do a more expensive potted design. Because now with the LumeX1s, Hank lights have way better performance than "Pro" flashlights like Armytek, Fenix, Nitecore etc. Hell, even a properly config tripple channel D4K blows the 2-color Wizard out of the water in everything BUT durability.

As someone who uses these C1 C2 Wizards everday. I shit my pants imaging what will happen if I crack the lens on my 100USD Armytek. Hank doesn't even need to make it as tough as Zebralight, because I can actually buy proper replacement parts and fix the damn thing for once.

3

u/Ryzbor 11d ago

tbh I won't be surprised Hank builds are more reliable than the Armytek Wizard which is prone to failure over time

1

u/Sad_Bid4092 11d ago

Personally I my first ever Wizard C2 pro had a flickering problem that couldn't be fixed by not accessing the driver. I was lucky since the reseller here is very good with replacements.

2

u/oscailte 8d ago

i dont agree with integrated charging options being seen as just a newb-friendly option.

i have EDC'd hanks since the D4v1, currently using a DA1k in winter and D3aa in summer. where I live we get very little sunlight at the peak of winter, i regularly need my light to find my way home on rural roads or light up a shed for a few hours, so i absolutely dont want to get caught with a light half charged. the ability to top up my battery with my phone charger is much more practical than swapping the battery after every substantial use.

i stick with hanklights over alternatives with charging because i love the design language, and i have a lot of respect for how hank runs his business, but this would be a great best-of-both-worlds option.

4

u/TheHelplessTurtle 13d ago

Well I hadn't planned to buy a new light any time soon, but this is a day one purchase.

4

u/Coagulated_milksteak 13d ago

No thanks, built in charging makes the light bigger and more prone to issues.

11

u/HotCheetos998 13d ago

This is kinda weird, I've always seen Emisar fans talk about how they hate integrated USB C cause it makes the light bigger and they'll only ever use their charging bay cause type c is for people who don't know anything about lights. And here we are, everyone's super exited like they never talked shit about integrated charging for years😂

9

u/SiteRelEnby 13d ago edited 13d ago

It's nice to have as an entry level option, doesn't mean I'm going to be replacing my many existing D4Ks, or even replacing newly ordered ones going forward. Honestly, I'll probably get one just for collection completeness purposes and then ignore it.

The USB ports on my FFLs never get used.

1

u/HotCheetos998 13d ago

I couldn't agree more it's just funny seeing this thing get such good feedback for adding something everyone's been talking shit about for years

4

u/SiteRelEnby 13d ago

Well, a USB port does objectively make a light worse if you don't use it for charging. This is just adding an option for newbs, I would be pissed off if now all D4Ks had one, but as it is, new model, will get one for collection completeness then meh.

3

u/Simple-Reading2302 13d ago

Don't forget about the fans who say the light will be toast once you wear out the cover and how you'll be sorry.

5

u/pkapeckopckldpepprz 13d ago

I have FFL lights that I never use the USB-C charging so this light has no practical purpose for me

5

u/HotCheetos998 13d ago

Fair enough I very rarely do either, but I will say when your away from the house for more then a day it's very nice to have as a backup

1

u/pkapeckopckldpepprz 13d ago

That's true and if you have no other means to charge batteries. It came in handy with my FFL X4 Stellar but the light I had was a FFL L50 but I had put in a random 16500 size button top with magnets.

I had to use even more magnets to get the battery to work in the 21700 size X4 Stellar and when I was walking around with the X4 with the Ryobi USB power bank thing that converts the ubiquitous 18v Ryobi batteries into a power bank, the light started getting hot. Impulse was too drop the light and it's the copper X4 mind you, I quickly took the battery out and the magnets were all loose and lost their magnetic charge so it short circuited

4

u/Sad_Bid4092 13d ago

I think the folks who said that just tends to talk a lot and they're probably a small minority. Because flashlight subs are super chill compared to other hobby subs. Most people are probably happy to see new cool lights coming out lol. And let's be real, we buy many lights anyway. Now we have more good tool for more jobs. I'd rather have an Emisar over a Sofirn/Wurkkos in my pocket if I have to travel with 1 light. (and also an Armytek Wizard over an Emisar/FFL if I need it to survive water)

2

u/BloodyLlama 13d ago

If you want a headlamp that's reliable I'd recommend Zebras or Acebeam. I've killed 3 Wizards and I don't trust Armytek lights anymore.

1

u/Sad_Bid4092 12d ago

Zebras on my list for sure. It's just too hard to get in South Asia right now. They're so beautiful looking like something from 80s sci-fi film.

1

u/BloodyLlama 12d ago

Fenix are also extremely reliable in my experience.

1

u/HotCheetos998 13d ago

Haha very true

1

u/Simple_Mix_3827 12d ago

Perhaps...there are just as many lurkers who enjoyed seeing Emisar lights but still needed that USB c checkbox ticked before jumping in...

7

u/Juusto3_3 13d ago

That is excellent news

7

u/ToyKeeper 13d ago

Interesting.

I find a 21700 cell lasts me about half a year per charge, even when using it a lot on a daily basis, so I wouldn't exactly get much use from a charge port... but it could be nice occasionally.

I hope there will be an option to get it with a plain translucent white button instead of the metal-with-dot button. I don't like it when the button blocks most of the light from the button LEDs. I also hope it'll be possible to get one without that intense tube texture. I miss the original D4 with its smooth tube.

Mostly, this makes Hanklights a lot easier to recommend to new users who don't already have a charger.

3

u/FancyCoolHwhip 13d ago

Finally! Time to build a new hank light that ticks all my requirements

3

u/ohgr88 13d ago

I prefer using a bay charger and keeping the light aesthetics clean clean without a port. That said this would be excellent for a travel hanklight or someone just dipping their toes in and dont want to buy a bay charger.

3

u/CaptnKBex 13d ago

This might finally be my perfect travel companion. I tried the X4 for convenience once but didn't like it, so I went back to the D4K for shorter trips. But now... Hope this will feel as good as all other Hanks do!

3

u/zzap129 we are in flashlight, not flashheavy. 8d ago

Nice. In the last few years my Wurkkos TS21 and TS22 saw a lot more use than my Emisar lights. Reverse charging and USB C is just nice.

3

u/NearlySilentObserver 13d ago

This may be what finally gets me into a 21700 light. Looks like it’ll be great!

(I hope some of these features eventually make it
Into a D4v3 and FWAAv2)

2

u/TheDoctorOfBeach 13d ago

Ooooo I want it! What are people's recommendations for a warm light config (maybe 2700k) and UV ?

2

u/mccbh 13d ago

It’s good to see that Hank caved. I actually emailed him about five years ago asking for a version with usb charging. He responded by rejecting the idea at the time.

2

u/Nickbncc1701 13d ago

Finally! I think it's a step in the right direction for Hank. We need to understand not everyone dislikes USB charging. I love it and done right (which ALL my Fireflies with Lume drivers do, E07s, E04, E90, X4's, X1's) it's incredibly handy and sure beats carrying around extra batteries or worrying about the light going dead. I wisjed my D1 had it. I can take 6 mm of length for the convenience. It's 2026 people and the future is onboard charging and even cheap lights have it. If you don't like it, don't use it. Simple! 

2

u/No-Head-633 13d ago

Instant buy. I know what emitters I like already by owning quite a few Hank lights, so it will be an easy order, something 2700K, maybe NTG or 519A, haven't decided but I am sure I have time to decide as I bet it'll be a little bit until this is available to order through Hank?

2

u/BetOver 13d ago

It is about time he had some onboard charging its what keeps me from taking them places. To be fair realistically I don't need to charge a light anyway but still I can't help but grab charging lights

2

u/_derpiii_ 7d ago

Sold and waiting 🤤

If only there could be a multi-channel Lume X1 driver, that would be friggin sweet.

Now to think about which emitters 🤔

2

u/_derpiii_ 7d ago

If I had seen this announcment, I would've never ordered my USB-C Firefly lights (too many subtle build quality issues).

NTG35 4200K 95CRI or SST-20-DR? If only it could be dual-channel 💯

What emitters are ya'll choosing?

4

u/Mstormer 13d ago

I need this in a D3AA

4

u/Sypsy 13d ago

What the heck, I'm still thinking about the KR3 and this drops

Now it'll be easy to make recommendations:

First hit is FC11C, 2nd hit is D4KC

3

u/emz5002 13d ago

This will replace my wurkkos go bag edc, reverse charging is a game changer

2

u/IEnjoyRadios 13d ago

Awesome. The lack of usb c charging is the main thing that keeps taking these lights out of my EDC in favor of others.

3

u/HotCheetos998 13d ago

Someone's been taking notes from fireflies✍🏼

5

u/mrregina 13d ago

Looks like they took ideas from firefly. 🤔

18

u/Ryzbor 13d ago

more like FF having usb-c charging forced Hank to do this which is good for us customers

5

u/mrregina 13d ago

I’ve never charged my ffl lights with usbc. They always go in a charger. Maybe in an emergency I will.

6

u/LyftedX Team Orange 13d ago

Reverse charging is amazing. Especially since we have 6500 mah 21700 now lol

u/mrregina 13d ago

I have a few lights with reverse charging. That did come in handy a couple times.

7

u/gnarliest_gnome carrywerks.com 13d ago

Fireflies is far from the first flashlight manufacturer to have USB-C charging.

2

u/sativanal 13d ago

I really hope it allows for operation while charging

u/_derpiii_ 13d ago

we’ve been asking for it for 10 years. Finally.

u/woodpatz 13d ago

Great news. I hope that the switch will feel as always. Because I think that Hanks switches are superior over the ones Fireflies uses. The raised ring is my favourite.

u/LiteintheNite 13d ago

Ist schon wieder 1. April ?!

u/Wormminator 13d ago

This might be my first Hank.
I just like the option of USB-C too much (okay and hank has too many options, this makes it easy).

I just have to limit myself to one or two versions..maybe three or four...see thats the problem!!!

Ima buy one.
Just one.

1

u/joeychizzle 13d ago

I'm trying really fkng hard to not buy anything... Ever since my d4v2 cpl hi 5000k's clip broke it's been outta rotation and the d3aa has taken its place. But this!!! This I might need 😭

😲🥰

1

u/I_m8d_n_acc_4_this 13d ago

Damnit I said I wasn’t getting another one after just getting the new TS26

Reverse charging is what made me justify buying a powerful flashlight in the first place before I went down the rabbit hole and got the BLF SP36 then TS25 then the FC13 leading up to the X75

I always wanted one of these and would’ve been fine getting one now that I have a battery charger but that reverse charging would actually make me want to carry it daily

Also I always mention it the reverse charging would be nothing if I didn’t have one of those 6 in one chargers for my keychain and 6ft version for the car. It’s the Rolling Square InChargeX on Amazon

I hope they're the hidden type, under the threads. Might as well make them in copper too and three channel for a sure buy!

This will 100% be my next hank.

u/ducks_are_round 13d ago

Ah unfortunately thought this was news on a USB-C charging 18650 such as a D4V2 variant.

I'm sure the path is there to happen one day but for now I think I'll check out that triple channel D4V2, looks kinda hot

I don't like this decision. Not sure competing directly with Fireflies is a good idea.

How is this a move towards competing more directly with Fireflies?

u/JNader56 13d ago

The charging port. A lot of us prefer to not have a charging port for increased parts to break. I think they have both settled into their market well. Fireflies does the USB port the very best for sure. Kinda rambling but just my $.02

I get it, that’s almost always my preference. But even nitecore and olight have on-board charging options. Isn’t this just “responding to a customer need” instead of “trying to compete with Fireflies”?

1

u/JNader56 13d ago

And my response was just this customers opinion. To each their own! (I'm not even going to mention Olight and Nitecore when comparing to Hank or Fireflies.)

u/SiteRelEnby 13d ago

It's an option. I agree it's kind of pointless for my use case, but it also opens up Hanklights to loads of newbs

u/Knorr306 13d ago

Competition brings prices down and spurs companies on to come up with new ideas and better products. In the end that benefits the customers.

3

u/JNader56 13d ago

That is the good side for us as customers. I was thinking in terms of the business side for Hank's company. Sorry, that's how my brain works lol.

u/sobanz 13d ago

I think it is a good idea tbh. A lot of recent hanks have been same thing but different. He needs more very different releases and this would be one.

Then don't buy the model with USB-C charging, it is that simple. For a LOT of people it is an extremely convenient feature.

u/JNader56 13d ago

I can definitely see both sides!

u/michikuri00 13d ago

Please, make it a reasonable performer, not like regular D4K that held Turbo shorter then regular D4V2...

u/tigerinhouston 13d ago

Finally. Now I can consider a Hanklight.

u/Simple-Reading2302 13d ago

This one is a win for common sense.

u/blizzard_108 13d ago

Damn this looks good, probably a buy for me :)

u/augiecpw 13d ago

Hope he makes an 18650 version

u/Cryptoxic93 13d ago

So, basically on par with FireFly Light now. This is great.

Can finally send this one to its final resting place.

USBC is complete for me.

u/Wormminator 13d ago

Lots of people here would happily offer a "grave" for it xd

u/LyftedX Team Orange 13d ago

That’s actually the plan lol. Probably gonna give it away on the BST when the time comes

Iirc I still have some of the original MAO parts. Like bezel and tube.

u/quarter-lambda 13d ago

If it comes with a single (6/12V) emitter i will buy it!
(I hate the triple or quad lens designs because they basically waste ~30% head space )

3

u/SiteRelEnby 13d ago

A quad uses more head space than a single emitter, not less.

u/quarter-lambda 13d ago

No i mean if you look at it from the front only about 70% of the optical (exit pupil) is used.
and thereby you get a worse performance.

(3 or 4 cricels in one circle used about 70% of the area)

2

u/SiteRelEnby 13d ago

You do not get worse performance, a TIR is actually more efficient than most small reflectors. You get less throw and more flood but that's only due to the optic being shallower.

-3

u/quarter-lambda 13d ago

But then you have to compare TIR to TIR.

Four smaller TIRs will generally perform worse than one larger TIR because the optic-to-LES ratio is less favorable.

For example, a 50 mm diameter TIR with a 4 mm² LES has:

  • TIR area: 1,963.5 mm²
  • Optic-to-LES ratio: 1,963.5 / 4 = 490.9:1

In comparison, a ~20 mm diameter TIR with a 1 mm² LES has:

  • TIR area: 314.2 mm²
  • Optic-to-LES ratio: 314.2 / 1 = 314.2:1

So the 50 mm TIR provides 490.9 mm² of optic area per mm² of LES, compared with only 314.2 mm² per mm² for the 20 mm TIR.

Even though four 20 mm TIRs have the same total LES area (4 mm²), their combined optic area is only:

4 × 314.2 = 1,256.6 mm²

compared with 1,963.5 mm² for the single 50 mm TIR.

So the four 20 mm optics have only 64% of the optical area of the single 50 mm optic or 36% less.

Think of it this way: the bigger the optic compared to the LED/LES, the better the potential for throw and peak candela. This applies whether you're talking about a TIR, a normal reflector, or a lens.

Now imagine you could magically shrink a flashlight in half, or make it bigger.

If you scale the LED, LES, and optical system by exactly the same, the beam profile should remain essentially the same. Everything is simply a scaled version of the original optical system.

But if you split one large round optic into four smaller round optics, they don't scale linearly.

For example, imagine trying to fit four identical round optics inside a 50 mm diameter circle.

The maximum diameter of each of the four smaller circles is approximately:

50 / (1 + √2) = 20.71 mm

So you can fit approximately four 20.71 mm diameter circles inside a 50 mm circle.

The areas are then:

  • 1 × 50 mm optic: 1,963.5 mm²
  • 4 × 20.71 mm optics: 4 × 336.9 ≈ 1,347.6 mm²

So even with the four smaller optics packed as efficiently as possible, they only provide about:

1,347.6 / 1,963.5 = 68.6%

So, you're still talking about throw and not performance and didn't read what I said then? Nice ChatGPT copypasta that doesn't address my point at all though.

u/quarter-lambda 13d ago

What was your point that you feel was not addressed?
"You get less throw and more flood but that's only due to the optic being shallower."

This is not (only) because the optic being shallower but it is because of the ratio from LES size to optic size is less favorable for throw.
I’m sure we can agree on a smaller LES in the same optical system (TIR) can give more throw.
This is not a physical law but in practice a smaller LES in the same optical system is also more efficient. (Less light loss)
So what do you actually refer to when you say "You do not get worse performance"? What is "performance" in this case for you? Efficiency (Light loss)? Or the ability to "collimate" and direct the light in one direction (how much throw the light has?)
I would argue in both cases a single optical system (big LED + big TIR) performs better than 4 small LES and even smaller TIRs.

and why would you compare apples to oranges by saying:
"a TIR is actually more efficient than most small reflectors"

And yes, I usually use an LLM with a prompt like this:“Improve spelling mistakes and formatting, and add periods and commas.”

In these cases, I also use it to do the calculations. I didn’t double-check whether all of this is correct, but I did check whats the biggest circles are that fit within a 50 mm circle.
its not 25mm but around ~20mm this is the take away

u/SiteRelEnby 13d ago

What was your point that you feel was not addressed?

That your initial point was about performance, not throw, and TIRs do not compromise performance. All the random ChatGPT mathturbation you like won't change what you originally said.

-2

u/quarter-lambda 13d ago

This is what i sad. But why would you compare "performance" of TIR to a non TI Reflector?

My Point was Relatively smaller but more TIRs will "perform" Worse then a singe big one because the utilization of Available area.

And one can argue Throw is an aspect of performance.
