IChroma 50's are repackaged as GE Sunshine lamps in a bright orange sleeve, I think. I don't use them cuz I use T8's and compact fluorescents, but I've seen them at Wal-mart and at a local home supply store that kind of resembles Home Depot. If you pull the lamp out of the sleeve a little, it says Chroma 50 or C50 on the end. regards, Bob
