Very good and bright 3W LED COB chip. This is my 2nd order (warm white) for my projects. It needs a heatshink to operate safely because its metallic body is thin. When it is powered with nominal range of 9 - 12 volts it gives a really bright result but don't push its voltage over 12 Volts because it will burn !
Fast shipping and very fast delivery. I ordered 2 pieces (warm white) and both arrived in perfect condition. I have tested one of them at 12 Volts and it is very bright. as expected. It did nt get too hot so i think it can be used without extra cooling. Very good product and very cheap price. Very satisfied!.
I will definitely order more of these. They run at full power at around 10 Volts, so to avoid destroying them, you should use current limiting driver: http://bit.ly/2vV29RT
