A range of bulb types can be used as grow lights, such as fluorescent lights, high-intensity discharge lamps, and led. Today, the most widely used type of indoor grow lights are HIDs, which have a high lumen efficiency. Metal halide (MH) lamps and high pressure sodium (HPS) lamps produce a color spectrum that is somewhat comparable to the sun and can be used to grow plants.
AZ supply a wide range of high intensity discharge lamps, among which the most popular items used as a supplemental light to plants are CMH 315W lamp, CMH 630W lamp, HPS/MH DE 1000W lamp, and HPS/MH internal reflector lamp. Featuring high lumen output, superior performance, low energy consumption, and long lifespan, AZ HID lamps greatly boost vegetative growth and maximum flower yield.
Types of Grow Lamps/Lights
Features of Metal Halide Lamps
Metal halide lamps emit light in the blue and violet parts of the light spectrum, which is similar to the light available outdoors during Spring. With the introduction of ceramic metal halide lamps and full spectrum metal halide lamps, they are increasingly being used as a supplement light for both vegetative and reproductive growth stages, suitable for supporting plants in earlier development stages by promoting stronger roots, better resistance against disease and more compact growth.
Features of High Pressure Sodium Lights
High pressure sodium lights are a more efficient type of HID lighting than metal halides. HPS bulbs emit light in the yellow/red visible light and small portions of all other visible light. As HPS grow lights deliver more energy in the red part of the light spectrum, they support plants in the stages of blooming and fruiting, used as a supplement to natural daylight in greenhouse lighting.
Application of HID Grow Lamps
All HID grow lamps require a ballast to operate. The bulb won't work properly if an unmatched ballast used. It's highly recommend to use AZ electronic ballasts to achieve better performance.
