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
This is a 940W HPS bulb that works with a 1000W MH ballast. If you bought a 1000W MH lighting system to use during the vegetative stage, then get this bulb to use during the flowering stage. Simply unscrew the existing MH bulb and replace it with this one and you're set. Ultra Ace conversion lamps are HPS lamps that operate on Metal Halide systems. Transforms a one-dimensional Metal Halide Lighting system into a complete growing system. Provides optimum red spectral energy required for flowering. EN designation means environmentally friendly in that the lamps pass EPA, TCLP test criteria as non-hazardous waste.Learn More$152.94
