Lighting 39V 2.1A COBs good/cheapish drivers?

[2Stoned2Care]

I have given up on passive heatsinks in the uk so i just used a 40cm piece of aluminum heatsink with 4 clu-48-1212s 4 bjb holders a 120mm fan and a hlg 185h-1400b driver with a potentiometer so i can dim the light from 200w to 20w.this thing is bright,even when people like @BigSm0 say you will be shocked when you turn them on,its an understatement sooooooooooo much light hahahaha

I like this quite a bit but may I make a suggestion for improving your design?!

It would be beneficial to cover the top fins with a thin piece of alu plating and flip the fan around (and if you got one; use a static pressure type fan)

You mean suck the air from the heatsink instead of blowing across it ?

 

[BigSm0]

He is right. Blowing or sucking wouldn't matter. It would allow the air to stay within the fins.

these heatsinks run at this power level just don't need the extra hardware, it barely needs the fan! Keep it simple!
