Hi everyone,

I've been on the road but finally got some time to do a little testing on this board. Overall, I'm impressed with it. The electrical and PPFD specs confirm that the diodes are legit LM301B and it's a nice compact little board/sink package.

I will jump right into it and add some more pictures of the board itself soon.

First, some temperature, voltage, and current testing. The current doesn't change much since the driver is maxed out, but the voltage and temp are worth having a look at. For temperature, there are 2 readings shown on the meter. The big number is the surface of the board and the smaller number is the reading I got from the top of the heat sink.

The driver used was a Mean Well HLG-120H-54A, as recommended by Atreum. I turned the pot all the way to max.

Here are the numbers after running for 1 minute:
After 17 minutes:
After 30 minutes:
After an hour:
And finally, after an hour and a half:

I did open air testing at 18" on the 288.2 and came up with these results:


I'm also working on getting 2'x2' tent numbers today at 12", 18", and 24", and I'll share these in a subsequent post.

Alright, here are my numbers in a 2'x2' tent. I've found that it's very difficult to get tent numbers totally balanced since it doesn't take much to throw one side off vs. the other (e.g. - one side of the tent has a wrinkle in it or a zipper flap, etc.), so I have balanced a couple of the oddball numbers to compensate. For example - if one corner was reading 600 and the opposite corner was reading 500, I adjusted them to 560 and 540. The net PPFD is the same; I just redistributed it to eliminate a few outliers.

The light performed very nicely in a 2'x2' and I'd say 18" is the sweet spot.

LEDG, thanks for the testing! I'm glad you found the board to perform well. If anyone has any questions, we are more than happy to help out.
