Better grab your sunglasses, your sunscreen, and a bucket hat because these NeoPixels feature a 3W RGB LED and are so bright it's like taking a vacation ON THE SUN. Alright maybe we're exaggerating, but these are really bright. These chainable NeoPixel LEDs are not only super-smart, they are ridonkulously bright with 3W total, compared to 0.2W of a 'standard' NeoPixel. Each order comes with one 3W NeoPixel LED on an aluminum PCB/holder/heatsink. Please note that even though the PCB acts as a heatsink, 3W is a lot of power to dissipate as heat so you may need an additional heatsink or fan or other cooling mechanism!
