LED what's the difference between 150W and 250W? Which is better?
This is only a different number of watts, it can not say which is better, look at the needs of it, if necessary, you can ask under the bright lights, which will be based on demand, recommend the appropriate LED industrial and mining lights.
We can use the formula of luminous flux = luminous efficiency * optical power to estimate the equivalent amount of metal halide lamp for 150WLED industrial and mining lamps
The power factor of the metal halide lamp on average about 0.8, while the LED lamps currently used in electronic ballast, high power factor close to 1, so if you consider the power factor, power compensation 214.3W plus 20%, about 214.3+42.8 = 257.1W.So, 150W's LED light is equivalent to 257W's metal halide lamp.
