The first delivered radiator did not work, they gave me an immediate replacement. The light seems dimmer than expected, which certainly play both the color of light, warm white, and the very wide viewing angle a role. At the, in my opinion, high quality of halogen light come the LED spotlight - not manage - at least yet. Did the way sought after receipt of the first, the defective device for a way repaired this. One can find on the net both power supplies and the LEDs, also in the set to buy for relatively little money. Assuming craftsmanship of the radiators can thus be repaired in case of failure quite.
Addendum: Had wanted to use the projector for indoors as uplight. But that part bothers FM reception and is one of my wireless mice checkmate completely. Got confirmed in the network the problem. As I understand it as electronics layman, it is up to the built-in power supplies. For the planned use of me so unfortunately unfit.
