I appear, I am called alive Sergio and in Spain, have been reading this Forum, which I can with my English evil. I have mounted some system of leds to 220v with http://www.dealextreme.com/details.dx/sku.13552 regulator for 1 Cree R2, the idea was to put 3 or but leds with a single regulator, what instalais you who request yourselves well of price by Internet? And another thing in the last assembly I have mounted the LED on a heat dissipator and this I complete is put to 65ºC of temperature, this within the margins? Thanks for the answers and intention with this fabulous forum. :twothumbs
