Frequently asked questions
Can I connect it directly to a 12 V supply?
Not recommended. A direct connection does not regulate current, so the LED can be overdriven or damaged. Use a constant-current LED driver matched to the chip's forward voltage and current.
Does it need cooling?
Yes. A 5 W LED produces significant heat, so mount it on an aluminum heatsink, ideally with thermal compound, to keep its temperature within limits and maintain brightness and lifetime.
