err, nm. I just realized how dumb that was. I just figured it out. It's a wave length, meaning it's a wave not a ray. The percentage is of the multiple bulbs? That still doesn't really answer it though. I mean if you had 500 bulbs and 90% were red that would be a solid amount. But that isn't something that scales well. I mean 5000 bulbs of 90% red would mean a lot more red.
