The Sun System® I is the most versatile of Sunlight Supply's line of sealed aluminum housing ballasts. Designed and manufactured to give years of trouble-free gardening, the Sun System I is available with a wide range of bulbs and reflectors.

Priced with a Super Sun Reflector and a Grolux Bulb!!
The Super Sun is our favorite reflector from Sunlight Supply. Despite it's size, this reflector creates an extremely large area of brightly uniform illumenesence. It weighs only 7 pounds! The reflector dimensions are 11-1/2" wide x 6-3/4 inches high x 21 inches long (25-3/4 inches with socket mounting bracket) It is constructed of white powder coated steel. It includes a spectral pebble aluminum insert which increases light output by 30%.

You get a FREE Bulb upgrade to a Grolux enhanced performance bulb -- you won't find this on any other site!
