1000W Metal Halide Lamp VS 500W LED Flood Light


There are many differences between metal halide lamps and LED flood lights. Recently, it is common to see the 1000W metal halide lamps in current lighting market. But the question is: How lumens can a 1000W metal halide lamp produce compared to an 500W LED flood light?

According to the survey, traditional 1000W metal halide lamp can produce 50,000 lumens to 100, 000 lumens, which usually depends on the type and brand of the metal halide lights. But there is a common mistake that most of client will use same power of LED flood lights as these old metal halide lights when replacing metal halide light bulb.

So this essay will show you the difference of lumen output between metal halide lamps and LED flood lights, which helps you understand how they can be converted to LED flood lights.

1. The meaning of metal halide lamp's lumen

Lumen is a measure of light that defines how much light a certain lamp can emit. When planning to replace any existing lighting fixtures, you must understand the lumen output. Supposing you have just installed a metal halide lamp that produces 100,000 lumens per 1000 watts, in that case, you don't need a 1000 watt LED light to replace a 1000 watt metal halide lamp, but you need a LED lamp with 100,000 lumens to replace the metal halide lamp. That's to say, when replacing any metal halide lamp with LED light, you need to consider the lumen output rather than focusing on the watt.

2. The comparison of LED light and metal halide lamp's lumens

If you want to compare the LED flood light with the 1000 watt metal halide lamp, here's an easy calculation for you reference. For each metal halide lamp, lumen efficiency is almost 60 to 110 lumen per watt. For example, a 1000 watt metal halide lamp can produce 60,000 lumens to 110,000 lumens. Similarly, a 500 watt metal halide lamp can produce nearly 30,000 lumens to 55,000 lumens. But the luminous efficiency of LED flood light is 170 lumen per watt, for instance, a 500W LED flood light can produce 85,000 lumens, which is 150% higher than the metal halide lamps.
