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

The biggest difference is: the luminous efficiency (same brightness prerequisite requirements, the higher the optical efficiency, more energy-efficient.) For comparison: the high-pressure sodium lamps (90-100lm / W)> Metal Halide light efficiency (70lm/W- 80)> electrodeless lamp (60lm/w-70)> energy-saving lamps (40lm/w-45), the above data in high-end products as a reference! Less than 80W of energy-saving lighting efficiency is higher. The actual use of common problems: One: sodium lamp energy saving, the color is very poor, light yellow, suitable for street lamps, and other color requirements Second: metal halide light source life is actually for two years, compared with energy-saving lamps, many of its shorter than electrodeless lamp: electrodeless lamp defect is that the actual electrical parts can not guarantee that the service life of 10 years (publicity), the other is very serious light fades, is very bright at first, slowly darken . Fourth: high-power energy-saving lamps (100w) energy saving light efficiency is low, but the measured current is much larger than the label on value, for example: a 110W energy saving lamps, the actual use of power is 170w. Finally mention LED and induction lamp facing the same dilemma, is the accessories not guarantee its long life, high luminous efficiency, low heat dissipation
