Ambient temps are probably your problem. Putting 150w of LED probably isnt going to help much.
I would think with a setup that small, with enough airflow you should be able to keep it right around ambient.
FYI st that current your cobs will take about 50v a piece.
Any cob under 40v will be fine. just add a 29D if you want another cob. Plan bether in advance next time to avoid things like this
lol ok, if youre tongue fucking your lights, there are bigger issues at hand than how you happen to wire them.
Is it really that hard to secure all your wires?
Cheap CFLs would probably be a better bet than anything you are going to throw together. I went the cheap chinese ebay route my first go-round with LED.
Never again, wasted weeks waiting for the pieces to arrive and didnt work properly when all was received.
