I'm still looking for a compact-ish heatsink so I can put this LED in the carriage light on the front porch of my house
It's a Lumileds gen 3 COB led, 27 watts if I do recall, somewhere around 3000 lumens, more than double the output of two 100 watt incandescent bulbs.
It's designed to replace commercial HID down-lights, so all the heatsinks available are small in diameter but very tall, and designed to contain a fan for the higher wattage units.
Here it is running on an Intel heatsink, designed for to forced-air cool a 35 watt CPU ... without it's fan, the heatsink is quickly overwhelmed.
