I have never heard of such a thing. Honestly, I wouldn't even waist my time with that. Buy them in the spectrum you want for whatever stage your plant's life is in. I really do not think that your "paint" idea would come close to working. There is more to the science of lumens, kelvins etc that help a plant to grow. Paint will probably just cover and cut off what your plant really needs anyway.
good luck

elway07 Reviewed by elway07 on . Change the color of a CFL...??? Hi, I have a weird question. Since there is a certain blue light Metal Halide bulbs give off plants need for there Growing/Vegetative period. Is there a way to alter/cover the bulb of a CFL to change the color of the light? Maybe a covering or something will work on the light. Some guy on another web site told me to spray pant the bulb. I thought that was crazy and totally not safe. Any one got any ideas?:rastasmoke: Rating: 5
