It seems to be a good light, and I just wonder how long it lasts. Mounted on a aluminium heat sink.

LED growth Light 30w module for 220 v AC. The light is Full spectrum, most efficient for plant seedlings & growing/ripening. Module assembly should be placed on appropriate heat sink, temperature (with heat radiator) Do Not exceed 70 degree Celsius for LED module. Without heat sink LED gets very hot soon & finely destroyed by burning. If heat radiator is large enough, it is possible number of LED modules with one heat sink.

Very hot, requires special cooling. Only with a ventilated cpu cooler I managed to keep a temperature of 40 degrees.

Needs quite a lot of cooling. You can see a little bit of flickering. May be relevant, if used in the living room :-). Good price
