The light I prefer for indoor growing is the Ceramic metal halide, called the "Color Master" Bulb by Phillipps. It has good red and blue, it is made to work in a hps fixture with a Magnetic ballast. These bulbs only coe in 250 and 400 watt sizes, and you have to order either horizontal or vertical, as they are not interchangeable.

I have had good luck with it, it's really the best of both lights.
