Vktech 10 Pcs 3W Extreme 460nm Royal Blue LED Plant Grow Light Bead Aquarium Fish Tank

For the price, these are great LED's. Bought these for reef lighting.

They really are royal blue/460nm. Although they make things "glow"(like UV lights) more than any royal blue light I've had before.

First impressions: color is great, but I think these lights are hotter than other 20mm star LED's I've had before. I do have a heatsink on them, the average lifespan for these kind of LED's is 5ish years, I don't expect these to last that long, but if I get at least a year out of these, it will be worth the price. I'll update this in 6 months.
