The LEDs do not have a heat sink that I'm aware of. It's made up of about 5 PCBs so it produces a 360 beam. It also has heat shrink over the current driver. They do give off a slight blueish color, but they also offer warm white if you're into that.
My coworker followed me into work today. Said the plate lights were the first thing he noticed (we go in before it's light out). Maybe too bright and recommended spraying something to diffuse the light more (car guy too).
