Scott, It really does not matter if you use incandescent or fluorescent light. What is important, however is the intensity and the wavelength of the light. Cacti, and all green plants, are incapable of utilizing green light. You want to supply red and violet light. These are the wavelengths that are useable by the chlorophyll. Plant lights are designed to supply these wavelengths.
