We offer this special heat sink for better heat conductive conditions in your high power LED applications and PCBs. This cooler has excellent heat conductive attributes because of its backside spikes. Those have a gathered surface higher than ever common cooler could have.

Only a durable and consistant heat management will cause a long lifetime of the LED.

Technic remark:

This cooler is perfect to cool PCBs like our LT-663 which is used for user defined LED applications and plug & light kits. A further advantage is its width of only 40mm which allows it to fit through every MR16 assembly ring (50mm).
