Cooliance Heatsink

Hey everyone - I had mentioned these pre-tapped for the Ideal Chip-Lok holder Cooliance Heatsinks. These are the passive cooling models, designed to operate inside a plenum. According to the rep, if you've got good air flow in the room, there should be no concern about keeping the operating temp in order. I'm going to be using these to build a veg lamp, as they do not fit the bill for what I'm doing with my flower light. The hockey puck on there is for scale idea. These seem like they'll do the trick quite well. Check them out. They weigh 1lb 9oz a piece

I was fantasizing about mounting an HBG Mean Well over an active Cooliance for a spot light.

...the first pin fin model i saw for 3590... curious for my pov.. thanks for info and link..

...i prefer some models on active radial heatsinks for cobs with lens or reflectors than active pin fin models... with ...some radial models put some freash air goes near lens or reflector zone... just my pov...

I think radial fins make good sense for passive as well, allowing upward air flow.

Pre drilled for cxb3590's makes it even easier to build a top notch light for beginners

Cooliance work great.
Most of the heatsinks you would want, aren't stock setup for the COB most would actually use. They based their wattage on a 85c temp, so for most of the DIY preferences, that's a little higher than desired. But if you check the spec sheet and are using high efficiency leds(>50%), you can predict performance pretty well.

@HockeyBeard What model did you pick up?
