China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

 Fluorescent magnetic and electronic ballasts are intended to operate an average of 50 000 hours (at maximum rated case temperature).High Efficiency ballasts deliver up to 8% additional energy savings over standard electronic ballast and even more when used with the new F32T8/ES (30 Watt) or F28T8 (28 Watt) lamps. The useful life of a Linear Fluorescent Ballast depends on the daily hours of operation and the operating temperature, the latter being the most critical. It is important to note that increasing the operating temperature by 10°C will cut the life expectancy in half, and lowering it by 10°C, will double ballast life.
