LED replacement for metal halide 400W has many applications, such as high bay warehouse lighting retrofit, factory, basketball court, outdoor sports field and large area lighting. The 400 watt metal halide is using chemical in gaseous state inside the lamp to produce light. Though it is a mature technology, it contains some toxic chemicals such as mercury and heavy metals that is harmful to environment before the LED retrofit of 400 watt metal halide equivalent flood lamps. Besides, the lighting fixtures are expected to be operated for long time; however, the life span of this luminary is about 3000 to 3500 hours. It is equivalent to a few months life cycle. And thus 400 watt LED replacement for metal halide is needed. LED takes the advantage of long life span – 80,000 hours at L70 (27+ Years lifecycle), mercury-free, anti-glare and effective heat dissipation, instant on/off.
High bay metal halide lamps are so popular and thus replacement or retrofit to LED is not very common in the past. It is because they have versatile application such as parking lots, airport lighting, warehouse, factory and mining lights at the height of 4 to 8 meters. Its energy efficiency is higher than that of incandescent lamps because the bulbs use different mechanism. Using electric arc instead of heating up the filament to few thousand degree. Therefore you can see there is a significant advancement in metal halide bulbs. Base on this, the LED replacement for 400 watt metal halide has further improved the lighting efficiency, life span and lighting mechanism. The LED retrofit kits utilize pure current to drive the particles to pass through the semi-conduction. It does not contain mercury and other toxic impurities. And thus it is energy saving and better for environment. Retrofitting 400W metal halide by LED has overwhelming lighting efficiency of 140 lm/W and 95% energy efficiency.
How to select a LED replacement to 400W metal halide
How many power to do the 400 watt metal halide LED retrofit? For the traditional MH lamps, the efficiency is about 40 to 50 lm/W. It is one-third of LED lights. So the question is how to select the appropriate lumen for the retrofit? You can see what 400 watt MH bulbs can produce is 16,000 lumen. The higher the lumen, the brighter the light. Therefore, in order to produce 1600 or more lumen, we only need 16000/140 = 114W LED for 400W MH equivalent. To provide better illumination, we can even select 150W LED for retrofitting or replacing 400 watt high-bay metal halide.
Let’s have a look on the amount of energy saved. Since we reduce the power of luminary to 150W. You save 250W energy and the electricity bill will be equivalent to 1/3 of its original value! At the same time, the brightness attenuation in MH is quite fast and significant in a short period of time. Within half a year, you can perceive that the brightness is significantly reduced for MH lamps. LED retrofit, on the contrary, you will not feel any difference until 80,000 hours operation, or 27+ years.
