The Lumenlite 250w Metal Halide Lamp is a vegetative stage, growth spectrum lamp which has been optimised to run with an Adjusta-Watt Ballast. During the growth period plants much prefer the blue end of the light spectrum giving fast upward growth and dense,close internodes which helps greatly when moving towards the flowering cycle. The LumenLite 250w lamp works well as a supplementray lamp when combined with high pressure sodium (HPS) as well as a stand alone fixture for excellent vegetative growth.
