T5 fluorescent lights are cost effective,
high-efficiency light sources. They can last up to 20,000 hours and contain
less mercury than older fluorescent lights, making them better for the
environment. This 2 foot, 8-lamp T5HO grow light fixture is a powerhouse, with
40,000 initial lumens and dual light switches to help regulate the lighting. The
Fulham Racehorse ballast gives you improved cold starting performance and
extends lamp life. Miro-4 reflectors give you even more focused light.
