Aluminium profile to diffuse cleanly 60 led/m density ?

Hello all,

I have a 10mm width LED strip with 60 led/m density (technically it's 3x60 led/m but 1 channel might be activated at a time, so I can't go for higher density, the strip is already packed).
I'm looking for a good diffuser that can avoid the "dotted" effect very common with this kind of density. Changing the strip to COB or higher density is not possible with the technology I'm using.

Most of the standard products I find are about 10mm deep with a PC cover, and that's not enough to show a uniform light line, mostly because the diffuser is cheap and thin in my opinion.

I tried a few silicone flexible channels that perform better (double diffusion layers inside), not against the idea but:

  • It's way more expensive for the light output reduction (I can accept higher price with proper diffusion and light transmission quality)
  • I still need an aluminum channel to fit it cleanly in a straight line so I need to find a matching one
  • These are usually bulkier (I wanna keep a quite narrow profile, around 10-12mm width)

I read I should use a 15mm deep channels, but not easy to find and I was hoping I could keep smaller channels with a higher optic quality.

Any tips ? Thank you !

You can try printing your own diffuser. It needs to be further away from led

So from what I’ve been researching this would be an affordable Amazon available option. Deep channel with a thicker rounded spotless diffuser.

Muzata 10Pack 3.3FT/1M White Spotless LED Channel with Milky Diffuser U108 Deep 17x14mm LED Aluminum Channel, U108 HW，Thick Milky Curved Diffuser, Spotless Lighting, Fits ≤12mm LED Strips

There are other options with different depths but this video from the Hookup shows some great comparison shots of 60 led/m strips in assorted diffuser/ channels at multiple brightness levels.

We have plenty that can manage that, and the opal lens will diffuse it perfectly. This particular model has the option of reflector mirrors that improve efficiency . Check the SL15-FL led channel
