TEK Lighting LED bulb lights

Many university playground lamps are obsolete, and TEK Lighting recently replaced its original golden halogen lamp for a university, instead of using LED stadium light . A part of in order to save money, and part of the reason is that brightness can achieve basic lighting requirements, in order to students health. In the past ,  people in the use of lamps and lanterns can produce two big mistake. First is everyone always thought that the greater the power, the higher the brightness, but the actual brightness is depends on power and luminous efficiency. On the basis of same power , luminous efficiency is higher, the total luminous flux is big. Used golden halogen lamp, after secondary light distribution of lamps and lanterns will loss a large part (loss: about 50% of luminous flux), combined with infrared and ultraviolet (uv) content (about 20% -30%) . And TEK lighting LED stadium light , using good quality chip, the single side of the light, through the pr...

Now many construction sites also stay in the use of 1500W metal halide lamp（MH） as a nighttime construction lighting, instead of using LED stadium light . A part of in order to save money, and part of the reason is that brightness can achieve basic construction lighting requirements, in this regard a lot of people in the use of lamps and lanterns can produce two big mistake. What are these two mistake? First is everyone always thought that the greater the power, the higher the brightness, but the actual brightness is depends on power and luminous efficiency. On the basis of same power , luminous efficiency is higher, the total luminous flux is big. Construction site now use 1500W metal halide lamp (light emitting Angle: 120 °) ,its total luminous flux is: 13500 LM, after secondary light distribution of lamps and lanterns will loss a large part (loss: about 50% of luminous flux), combined with infrared and ultraviolet (uv) content (about 20% -30%) , 15...
