400/600/1000W High Pressure Sodium (HPS) Bulb Hydroponics Grow Light.The HPS grow light bulb can produce a very balanced and efficient spectrum of lights, brings you the best yields in flowing, budding and fruiting. It emits a red/yellow spectrum that is among the most energy efficient sources of indoor sunlight and extends the growing season. High Pressure Sodium HID light bulb is an efficient lighting solution for industrial applications such as warehouses, post top lights, and parking lots. It has a long life of up to at least 24,000 hours.HID HPS bulb is ideal for use in security lighting, roadway lighting and warehouses. HPS grow lights tend to be much more efficient than other alternatives and have a longer life span, saving you money on energy bills and replacements. Although they are about 30 percent more efficient than incandescent, much of the power consumed by an HPS lamp is lost as heat. Because these lamps do put out a lot of heat, it's important to keep them about 12 to 18 inches away from the plant. Anything closer than that will start to burn most plants. The heat generation may be an issue in warmer climates or the summer months, but it can help mitigate the cold in the winter or colder climates.
