Full Sun Lamps
Ceramic Full Spectrum HID or HPMH (High Pressure Metal Halide) are the most effective lamps for all stages of plant growth. One lamp for all, with no need for switching from Metal Halide (MH) to Sodium(HPS) during vegetative and/or flowering stages. These lamps have more reds than any type of HPS and also produce the perfect amount of orange, yellow, green, blue, violet and UVA and UVB spectrums needed to simulate the sun. Just like the sun light that hits the Earth, these lamps produce in phase energy, in wavelengths from 380-740nm. These lamps are the most efficient lighting source available, produced in sizes of 100w, 150w, 250w, and 400watts.
