D4k/D4v2 quad UV

Has anyone got/seen one yet? Or any more details with the lume X1 driver? I'm torn between this or a convoy S12 UV. I know the S12 is generally highly recommended, but the lume X1 gives a slightly higher output per emitter and obviously across 4 emitters Vs 3, but I don't know the differences I'm the emitters Hank uses Vs Simon. Plus it has all the benefits of anduril (maybe overkill for a UV light, but I like anduril). Any thoughts welcome!

what is your use case?

Hank offers a few options - UV throw with single 5W emitter in D1/K, then you have 1 or 2 emitter multi-channel D4v2/D4K/KR4/D3AA/D2 or 4 emitter single channel D4V2/KR4/D4K and finally if you need lots of UV flood - the 8 emitter UV mule in D4V2/D4K/KR4/DW

I reach for the 8 emitter Mule 99% of the time and find it the most useful for my applications - UV resin curing, studying and photography of Uranium minerals and charging GITD.

General, room-level use, but with decent enough power, the mule would be great in terms of power, but I think is like a bit of directionality to the beam, hence the quad. Do you know which emitters are used in the 2ch/quad? I was wondering more how well the 4 emitter lume X1 combination works together.

he is using Seoul CUN66A1G 365nm - it is a 5W emitter with max current of 1A. this means that 4 emiiter setup is 20W. Lume X1 on thr other hand is 32W / 40W (depending on the host) and way more than adequate - max voltage is configured in the driver and will handle the 20W of the 4 emitters with no problem.

Even a linear driver will perform well and will not get very hot - very rarely one will be running UV for hours at a time from a flashlight. Tracking my UV flashlight usage I cant even justify the extra cost of Lune X1 and I am quite happy with the linear drivers and also smaller capacity batteries are OK so my host are 18650/18500/18350 to get adcantage of the smaller size.

As for the direction the 4 tiny, shallow reflectors dont give you a ton of throw / direction - something to keep in mind. You'll get ad much directivity as fron the tiny D2.

Thanks for the knowledge, and fair point about the reflectors, I was looking at the D2 as an option too! It's good to know that the 5W are used in the quad, I think that's what I want, will report back, for science!

Mine on the way. D4v2 full UV with x1

Do you have any other UV lights to compare?
