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.
