NIce product, works ok Bought 2. Tested at 18W, current is 0.285A (slightly less than 300mA, but it's good for lamps life), trafo and IC heated at cca 40 Celsius in free air (dismantled) after 1 hour of operation. I suppose will be to 55 deg in the casing but I remounted it and I'm too lazy to dismantle it again to insert a probe. Overall is a very good product. Suppose will last, I hope.
thank you
