Top 5 Positive Customer Reviews for 30 w led
well packed,was open but everything was OK.i can't compare because chips are without brand,power,volts-nothing.can see the photo.more:"+ " and "- " are stamped on the wrong side so you can't decide which one is + or -.use a multimeter and find it.the base looks aluminium but it's not-just cromated steel.fits my old projector place and already installed one.i'll wait to see durability.actually is OK.
Fits really well on the 1 Watt LEDs with the star PCB. But there seems to be no place to route the wires. This seems to me as a bit of oversight. The lens however works really well.
!! Attention !!! For the 4 pinsleds (3W) one pin has a "-" on it, this is a Do Not Connect pin !!! Not the ground The VCC is the big metal pad UNDER the LED, and the 3 other pins are the R, G and B grounds. This is why, I think, other buyers say the led don't works .... They works ! :-)
