Prolight LED on heat-sink

A white 25 lumen, 1W Prolight LED mounted on a heat-sink. Used as a night light.


I used this 1W white Prolight LED inside an old light fixture to serve as a night lights in our old basement. It emits a total of 25 lumen in 140 degrees, the light intensity is equal to a 5 to 10 Watt bulb. Low power consumption and perfect as a night light, or inside closets etc. Powered by: 5V.

Between the LED and the heat sink there is some heat conducting film, to better dissipate the heat.
