I've been trying to find out how many diodes are the 560mm length EB gen 2s. The 280mm have 33. So I'm assuming they 560mm have double with 66 diodes. But I'm not sure. Arrow shows both the 280mm and the 560mm only have 33 diodes. And I know they have more than 33 on the 560mm. Anyone know off the top of your head? It's not in the datasheet and I've Google searched with no avail. I'm building a light. Was gonna go with 24 280mm strips. But to save on cutting aluminum more. I'm gonna go with 12-14 560mm strips. Just tryna figure out diode count.

All I can chime in with at this point, is that EB Gen1 560mm have 48 diodes, and the Gen2 definitely has more, because they're tighter packed and smaller....
Alas, all the Gen2 EB's are at a different location, so I cant go scope one out just now....

P.s., cutting through angle aluminum or U channel is surprisingly easy with a hacksaw and a nice new blade. It's like butter...

Digikey listing of EB gen 2 strips say the 560mm has twice the current draw of the 280mm strips, both at the same voltage. So, that means 280mm strips have half the LED chips of the 560mm strips.
Looks like 66 chips is right. I didn't count the chips.

Yeah I figured it was exactly double. Bc of the current. And double the length

If the markings on the board are correct the gen 2 280 strip has 56 and the 560 has 112. I just went and looked at both.

Lol guess I couldve counted the 280mm strips I have. I just assumed it was 33 NC both arrow and digikey say 33 diodes on their website. But 112 is even better. Double what I thought it was gonna be. Appreciate everyone's help.
