LED high bay light compared with high-pressure mercury lamp parameter

Traditional warehouse lamp with 250 w and 400 w high pressure sodium lamp and metal halide lamp, and compared the characteristics of the new type of LED lamps and lanterns has more obvious difference, as shown in the table below:

Considering the actual use of high pressure sodium lamp and metal halide light failure and secondary light problem, its actual luminous efficiency is far lower than the 80 lm/W, often cannot achieve the nominal 7.In this for the first time, we developed LED high bay light set about 80 w power, once the illumination effect is in line with expectations, than traditional lamps and lanterns namely energy saving more than 50%.
