There is a big difference between the metal halide lumen versus LED, 1000 watt and 400 watt MH are very common nowadays. So how many lumens does a 1000W MH lamp produce vs LED? And what wattage conversion should I adopt if I want to do 400 watt MH replacement or retrofit? This chapter will give you a brief idea on LED versus metal halide flood lamps’ lumen output and how to properly convert and retrofit to LED lights.
1000 watt metal halide lumen vs. LED lumen output production
Metal halide lamps are invented in 60s. Since then, it is still the most widely used high-power light source in the world. It’s primarily designed for wide-area such as airport apron, hangar, warehouse, parking lot, billboard, sports stadium, tennis court, football field and more.
Many people will attempt to do the LED & 1000 watt metal halide lumens comparison. How many lumen do MH lamps produce? 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. Similarly, 400 watt MH produces at least 24,000 and at most 44,000 lumens. How about LED flood lights? The lighting efficacy of LED is 140 lm per wattage, which is about 130% higher if you make the comparison of 1000 watt metal halides’ lumens with LED.
Why there is such a significant difference? It is because the ballast of metal halide can transfer energy of 60-80%, which means considerable amount of energy is wasted inside the ballast. If you want to produce the same lumen output for 1000W metal halide, you require 1200 to 1400 wattage power input indeed, which decrease the lighting efficiency to 36 to 88 lm/watt if you take this factor into account. 400 watt LED replacement and retrofit for 1000 watt MH, and hence, is a wise choice.
Although high power LED has a relatively short development time of 10 years, its energy efficiency and LED lumen raised faster than metal halide. 1000 watt equivalence LED can offer 130 to 200 lumens per wattage. Besides, LED power supply driver has 95% transferring rate, which means very high conversion rate. The actual lumen for LED is 95-190 lm/watt which is 200% to 300% higher than metal halide. In fact, LED is a directional light, which means it is easy to reshape the light direction. The Light Utility Rate and thus lumen of LED is 30% higher than 1000 watt Metal Halide.
