I have in my living room ceiling light with a 6x G4 lamps. Each lamp uses about 20W.
So I thought 120W, it need not be, I have found me without further ado this Tarfo and matching LEDs with 1.5W per lamp.
The Einabu is simple, most ceiling lights have a built-in transformer to expand, these. The incoming power is connected to the "primary" marked side, the outgoing current to the "secondary" side. The secondary side is now directly connected to the cables of the lamp. Easy..dauert not too long, and who has problems can even watch videos on the Web. Transformer funtioniert great and for me as a layman to understand well. The only drawback, it is somewhat large, which can cause problems with the ceiling lights covering mitsich.
Therefore 4/5 stars.
