Replacement of 250W Metal Halide Lamp with 100W LED Flood Light

First of all: we come to compare the 100W LED flood light and 250W metal halide floodlight luminous flux. From the data point of view, 100W LED floodlight light is less than 250W metal halide lamp luminous flux value.

Then, here to mention the effective luminous flux (pupil lumen PLM), the effective luminous flux of the human eye pupil for the total luminous flux of the direct visual response, LED light source of the effective luminous flux is usually about 95% of its own luminous flux, Luminous, all projected down to the work surface.

So the effective luminous flux of 100W LED flood light should be about 9800lm, and metal halide lamp luminous flux is usually only 60% of its own luminous flux (metal halide lamp contains many invisible light, such as ultraviolet, infrared, etc., about 40% , And because the metal halide bulb for light, rely on the reflector to reflect the direction of the work surface, so they lost part of the luminous flux, calculate the effective luminous flux should be about 10800lm. Its effective utilization rate is relatively low, reach the work surface also 9100lm or so.

     It can be seen, 100W LED floodlights and 250W metal halide floodlights the effective luminous flux is almost the same. With the LED lighting products in more and more areas, people can often see the LED lighting products, usually the first reaction that is bright LED lights, I think this is to fully explain the LED light source effective luminous flux is relatively large the reason.
