It is also an excellent lamp for full term plant growth. These lamps have been specifically engineered for horticulture applications. Ultra Sun lamps are high quality, feature robust construction and have excellent reliability at an economical price. One year warranty.Learn More$23.53
400W, 600W, 1000W SUPER high output HPS with maximized output in both red and blue spectral range.
SUPER HPS bulb with maximum output in both red and blue spectrum.
Runs on HPS Ballast.
Optimized for maximum flower yield, and added blue spectrum for vegetative growth efficiency.
Outperforms standard HPS bulbs.$54.12
Provides 25% more energy in violet, blue and green spectrum than standard High Pressure Sodium.
The combination of Super HPS and the Metal Ace conversion lamp provides the optimum spectral energy levels through all stages of plant growth.
EN designation means environmentally friendly in that the lamp pass EPA, TCLP test criteria as non-hazardous waste.Learn More$72.94
The Ultra Sun MH Conversion Lamps are designed for those who have an existing HPS ballast that want to also be able to run metal halide lamps without purchasing a separate metal halide ballast. With a 6500°K temperature, these lamps are excellent for the vegetative cycle of plants and full term growing. These lamps have been specifically engineered for horticulture applications. Ultra Sun lamps are high quality, feature robust construction and have excellent reliability at an economical price. One year warranty.Learn More$57.65
Blue Ice Grow Lamps emit light from 5,500°K, imitating the natural look of daylight. They are an ideal light source for the seedling and vegetative stages of plant growth, while still emitting a wide spectral distribution. Sunmaster® Blue Ice Metal Halide Lamps surpass many other HID sources in PAR watts - the most objective measurement of total light energy available for photosynthesis. Designed for optimal performance on electronic ballasts.Learn More$57.00
