Long Life - Up to 24,000 Hours High Efficacy up to 140 LPW Low Total Cost of Ownership Rated average life is the life obtained, on the average, from large representative groups of lamps in laboratory tests under controlled conditions at 10 or more operating hours per start. It is based on survival of at least 50% of the lamps and allows for individual lamps or groups of lamps to vary considerably from the average. For lamps with a rated average life of 24,000 hours, life is based on survival of 67% of the lamps. Approximate lumen values listed are for vertical operation of the lamp. Approximate lumen output at 40% of lamp rated average life. Follow fixture manufacturer’s recommendations regarding proximity of ballast to bulb. Fixtures should be designed so that sockets and wiring withstand starting pulse up to 5000 volts for 1000 watts and WHITE SON® types and 4000 volts for other sizes. For use in fixtures which do not redirect a substantial portion of the energy toward the arc tube; otherwise very early failure is anticipated.

Combining the two spectrums of the MH and the HPS lamps, makes this lamp great for all my indoor gardening, as a matter a fact, I use it on my fresh herbs I grow all year long in my bay window in the kitchen. This was the pefect idea for getting maximum lighting with a complete light spectrum. When winter rolls around I plant my cherry tomatoes and they grow great, enabling our family to eat cherry tomatoes at christmas time, its fabulous. Good lamps make great plants!!
