Before led lighting became the powerhouse that it is today the most common form of commercial lighting was metal halide lights.
How to convert metal halide to led.
For metal halide 70 of its lumen output calculates to about 5000 hours.
Led maintains its lumens much better.
Metal halide fixtures are used commonly in post top lights street lights and in warehouse high bay fixtures.
We explain a few things to know first and then we explain the conversion chart of metal halide to led.
Edison lighting supply shows you how to retrofit 400 watt metal halide lamp for led.
This is because metal halides are extremely bright lights that can be purchased for a relatively cheap price.
You can easily replace a 250 watt metal halide with a 60 watt or 80 watt corn bulb and save over 70 off your energy bill.
We often get asked the question can i replace metal halide bulbs with led bulbs in the same fitting whilst this would be nice and convenient it is unfortunately not possible at present.
So while the specs say 100 000 lumens it won t be 100 000 lumens for long.
Although the energy savings in going from cfl to led is not as dramatic as when they changed from metal halide to cfl the labor savings will have a big impact while most high output cfl lamps have a life expectancy of about 10 000 hours eledlights corn lights are warranted for 5 years and have a life expectancy of 50 000 hours.
You should look for a led fixture that produces over 10 000 lumens to replace 250w metal halide.
As most of us over 30 year olds can testify things that were totally impossible are suddenly and surprisingly ubiquitous the next minute.
That is not to say it will never be possible.
You will notice l70 times for leds are 50 000 and 100 000 hours not 5 000 hours like it is for metal halide bulbs.
Remember metal halide bulbs degrade relatively quickly and lighting systems are designed to take that into consideration as should you when selecting your led bulbs.
With today s efficiencies you can replace 250w metal halide with as little as 40w led assuming high lumens watt.
Our 120 watt is an ideal replacement for 400 watt metal halide.
The reality is that they come in a large variety of options.
Jump up to 150 watt if you want a 400 watt metal halide replacement.
See our blog on lumens for replacing 400 watt metal halides with led.
Commonly a 250watt 400 watt or 1000 watt.
