Sorry to drop out for a bit #bobsakamoto Here's the shopping list for the light I'm building as a prototype to hang at local garden shop.
3 Vero29s BXRC E3510K0-C-73SE, the C is a very important letter. The gen7s are B,C,Or D. Each group operates in different current and voltage ranges.
1 Meanwell HLG 320H C1400B
3 Mechatronix Giga 15250 heat sinks which come pretapped for Vero29s.
You'll need some framing materials, a cord, a switch, a dimmer (potentiometer), and for about 300 bucks you'll out perform a 315LEC with 50% more light and about 290 watts total usage.
I get the cobs from Digi-Key. The driver from Arrow. The heat sinks from CSI
The heat sinks are currently sold out world wide. I'm subbing with Mega 134100s which will add about 20 bucks to the build.
Go to the manufacturers web sites and read,read,read. It's all there.
If you go ahead with it, we could probably exchange emails or something.
