I have bought a 1 watt led. It is fitted with led driver which give output 300mA from input of AC110-240V at 50/60Hz. when i have connected to my power line. after few minutes the led driver became hot and burned. what is the problem. what i have to do to make my led to glow.
Depending on the driver, it may be intended to be mounted to an external heat sink/housing. Without some details on the driver specs, there's not much more I can tell you.
