These are the types of lamps commonly used for indoor growing:

1. Fluorescent Tubes

For beginners and lamps with moderate needs. Budget-priced and easy-to-use lamps.

2. CFL - Compact Fluorescent Lamps

Quite new kind of lamp. Highly efficient but quite sensitive.

3. HPS Bulbs with standard ballast

These bulbs are the most common. Excellent output for little money. Because of their need for a ballast the installation is more challenging but they are highly recommandable for most grower needs.

4. HPS Bulbs with electronic ballast

With this ballast the lamp is used more efficiently and lasts longer. Also the installation is much easier than with the common ballast.
