LP Sodium Lamps

Marijuana Horticulture

by Jorge Cervantes

Low Pressure sodium lamps are monochromatic. Do not use these amps to grow cannabis. They produce light in a very narrow portion f the spectrum, at 589 nanometers, and emit a yellow glow. They are available in wattages from 55 to 180. Their lumens-per-watt conversion is the highest of all lamps on the market today. Their main use in industry has been for security or warehouse light.

Lamps require specific ballasts and fixtures according to wattage. The fixture for a 180-watt lamp is just a little larger than a fixture for two 40-watt, four-foot fluorescent tubes.
