# Where can I find a 20mm Triple XHP50.2 / XHP70.2 board w/ LED's?

I tried searching everywhere in the matrix but can’t find anywhere that sells it.
Something like the pic below, 20mm w/ triple XHP50.2 or XHP70.2!!!

The reason you’re having trouble finding them is because COTS (commercial off the shelf) triple optics don’t fit 5050 or 7070 LED domes so there’s not a lot of demand.

What are you trying to build? What’s your plan for optics?

I think a square with 2 x 2 xhp.70 touching each other,7 x 7 mm each, is a 14mm square, requiring a circle of sqrt(2) * 14 = 19.8mm. 2x1 is 14mm x 7 mm, requiring a circle of sqrt(14*2+7*2)=15.6mm. 3 xhp70 would be something in between, closer to 4 than to 2. Look at a 20mm triple xp-l and imagine the leds doubling in size.

They would barely fit by themselves in the board. That leaves very little space for soldering paths, clearance, heat disipation, etc. I guess a triple xhp50 may fit but thermal performance would still be poor.

Wait, don’t XHP-50 fit on XM boards? Aren’t XM also 5050 size?

Yes, you can run XHP50 / 50.2’S on XM boards in 6v config.

Yes, but the OP wants a triple XHP50/XHP70(.2) in only 20mm. I don’t think triple XM-L(2) in 20mm were common either (or even existed off the shelf) before they became obsoleted for that format by the XP-L. In fact I can only find references to a triple XM-L2 in 35mm.

Here’s a triple 4040 footprint. Look how tight it is:

People have done some creative stuff with 10mm DTP boards but like CK said you are probably going to have to find 3x single optics or something.
