Electronic Ballasts for Grow Lamps

Electronic ballasts will help your lamps run cooler and more efficiently, so a significant percentage of the energy the lamp draws can be converted to usable light. They regulate both the electrical current and the frequency, thus eliminating lamp flickering.

Electronic ballasts are adjustable, so you can use them with lamps of varying wattages, which is quite handy for switching out lamps for different stages of plant growth.
