What is the difference between LED miner's lamp 150W and 250W? Which is better?

The formula of luminous flux = luminous efficiency × optical power can be used to estimate how many watts a metal halide lamp is equivalent to 150WLED mining lamp. The calculation method is as follows:

1. According to the current market, the general light efficiency of LED lamps is 100Lm/W, and that of metal halide lamps is 70lm/w;

2. Total luminous flux of150WLED lamp =150W×100LM/W =15000LM;

3. According to the light power = luminous flux ÷ light efficiency, if the metal halide lamp reaches 15000Lm, then the required light power =15000 lm ÷ 70 lm/w = 214.3 w;

note:

The above is an estimate, without considering the power factor of the lamp.

The average power factor of metal halide lamps is about 0.8, while LED lamps currently use electronic ballasts, and the power factor is close to 1, so if the power factor is considered, the power compensation of 2 14.3W plus 20% is about 214.3+42.8 = 257.1w. ..

Therefore, 150W LED lamp is equivalent to 257W metal halide lamp.
