About Osram
Why Osram
The Vialox NAV-T is a commercial-grade HPS lamp with a high, stable output over a long life, made by one of the two big lamp makers. The T5 tube is the blue-spectrum replacement for four-foot propagation fixtures.
Lamp life
Change HPS lamps after about a year of use; output falls well before they fail. Ballasts and reflectors under HID Lighting.
Growers' Guides
