Is a pink colored bulb the best for growing plants or is it a gimmick
mohican said:Funny, I've wondered same thing. They suppose to have proper k value for plants, but so does a 5-10k bulbs. Sorry I'm not helping but maybe someone experimented with the difference.

Something like a Geisemann AquaFlora bulb, that happens to be pink, is an exceptional bulb, especially when mixed with a Midday to equal out the overall hue. Realistically, in a low light setup with lower end bulbs, about anything in the 'daylight' range is going to be acceptable.

the only reason to me that a pink bulb could be useful to plants is because of the light spectrum it emits, which i assume the box will tell more about. this link shows the ideal spectrum for plants. http://www.akvariegoedning.dk/images/stories/billeder_til_artikler/plante_spekter.png
the other thing to keep in mind is that the bulb might not emit as much lumen as a regular bulb, however a regular bulb emits different light spectrums. the ideal light for an aquarium is a mix of spectrums that comes as close as possible to the linked graph.
