I've just discovered these are available ... super high power , up to 300W , in a very compact size , making them ideal for powerful zoom-able torches or spotlights ....
But my question is what does the white block in the right hand corner do ??? It's described as a "a high quality thermal resistance" ... Is this a cutout if the device should get too hot ??? Leds do not normally have current limiting resistors built in it would restrict usage and limit design ..
Power input is 12V current over 20A!!!
