No, halogen lights are useless. Wattage means nothing. You want the most lumens possible. You want the red and blue spectrums of light. Halogen puts out too much white. The reason Flouros only take less than 120watts is because thats what they are designed to do. But a lot of them still produce plenty of lumens. I have two CFs that i got from homedepot that produce 2000lumens each. Thats plenty for one plant.

The difference between all the lights, is very simple. Ive already mentioned lumens. Well, the MH and HPS lights produce MUCH more lumens then CF lights ever could. However, CF lights are cheap, efficient and dont get hot. MH and HPS lights can get rather expensive and hot, needing money and more money for ventilation. Regular bulbs just dont cut it. They dont put out the right light spectrum for plants to complete a correct photosynthesis process.

If your interested in buying different setups, look around on ebay. Do a search for: MH Setups. Or if you prefer search for: HPS setups.
