Property me worried these radiators to the electricity prices rise so my old 150W projector to ersetzen.Da constantly. I must say, gee! I did not think that there comes out so much power, while only about 12W consumed! Just awesome. Since it is light "rounding", he radiates, at least for my purposes "super left and right, and not just straight, and thus illuminated from a relatively large area. For my purposes, a really great and inexpensive replacement. 4 stars for the reason: All of my 150W burner he comes not ran, but almost. Oh: The installation really is absolutely simple, so do not shy, self-explanatory even for laymen. MfG Michael
