400 Watt Metal Halide Lumens Vs Led

What is hard to cross in is that metal halides actually start out at very high efficiencies.

400 watt metal halide lumens vs led.

Which means if you replace a metal halide bulb with an led you ll have a brighter light that also consumes less electricity. Both metal halides and leds are considered to be more energy efficient than incandescent lamps. For a very general and quick reference on how many led watt is needed to replace metal halide bulbs for you the brightness lumen output of 1000w metal halide is equivalent to 400w led and the 400 watt metal halide is equivalent to 160 to 120 watt led. Commonly a 250watt 400 watt or 1000 watt.

How about led flood lights. All the conversions i can find claim a 100 120 watt led with less than 12 000 lumens is a replacement for a 400 watt metal halide with 36 000 lumens. I ve been looking into led replacements or converting some older fixtures to led. When getting led fixtures the most important thing you should look at are the lumens each fixture produces.

In the above example we compared a 400 w metal halide bulb with a 150 w led retrofit kit. A new metal halide bulb can get almost 100 lumens to watt. Most large fixtures use metal halide bulbs. They are able to produce more lumens with less wattage.

We call that a win win. A metal halide light that produces 30 000 lumens discharges 75 lumens per watt. Similarly 400 watt mh produces at least 24 000 and at most 44 000 lumens. A new 400 watt metal halide lamp is rated to last up to 20 000 hours.

However when it comes down to the numbers the energy efficiency of an led far exceeds that of a metal halide lamp. If the initial lumens produced by each 400w metal halide fixture were 30 000 you should get led fixtures that produce 30 000 lumens. All the conversions i can find claim a 100 120 watt led with less than 12 000 lumens is a replacement for a 400 watt metal halide with 36 000 lumens. According to our research the luminous efficiency is about 60 to 110 lm watt.

Therefore a 1000 watt metal halide produces at least 60 000 lumens or at most 110 000 lumens.
