Fluorescent will also consume WAY less power and make way less heat then a HPS or MH type of bulb. I would in NO way ever want to attempt to use a halogen bulb to support a plant. Halogen does not have enough of the correct spectrum of light your plants are looking for so you have to run more halogen's to make your plant's really happy, but halogen is the cheapest and can be purchased almost anywhere. Once you have the correct type of light spectrum plants are looking for it is all about lumens nows. 8x4' T5 fluorescent fixture can be equal to 450 Watt MH.
