Here’s a shot of one of my very bright work lights. It’s a 10 watt multi chip LED mounted on a heat sink, which gets a bit warm. I mounted the heat sink on a piece of 6 AWG bare copper wire which lets me reposition the light a bit.
It’s a daylight color temperature, but I have some of the same LEDs that are warm white. I powered it with a 12 volt wall wart and a switchmode DC – DC converter. I can adjust the current and brightness.
