Metal halide lamps generate a very cool white light.
Metal halide vs led lumens chart.
Efficacy is a measurement of how well a light source produces light.
In this case we ll be comparing leds and metal halides but all bulb types can be quantified with this measurement.
Most large fixtures use metal halide bulbs.
The greater the lumens the brighter or more intense the light.
A metal halide mh lamp is an electrical lamp or bulb that produces light by creating an electric arc combining a gaseous mixture of vaporized mercury and various metal compounds bromine or iodine.
The table below compare the lumen and lighting efficiency of the metal halide and led lighting products on amazon.
Of course not every fluorescent incandescent metal halide etc lamp will give its lumens.
Commonly a 250watt 400 watt or 1000 watt.
To replace it with the same intensity led just look for one that rates around 2300 lumens.
Understanding efficacy is also important to understand why leds save you so much on energy costs.
Studies have shown that the blue wavelength in light increases the overall growth of plants.
It comes in a wide range of wattages from 250 to 1 000.
Efficacy lumens watt led vs metal halide.
A 40 watt fluorescent tube for example is rated around 2300 lumens.
Mhs have been used in growing cannabis because they emit a strong blue wavelength which helps the vegetative phase of growth.
Many 400 watt metal halide lights deliver 32000 to 40000 lumens while numerous manufacturers recommend that their 100 to 150w led corn light bulbs can replace the 400w metal halide.
Leds are available in a wide range of color temperatures that generally sp an from 2200k 6000k ranging from warm yellow to light or cool blue.
Photopic vs scotopic lumens.
A type of high intensity discharge hid lamp this light is typically used in high bay lighting fixtures in warehouses parking lots and hangars because of their high lumen output.
In fact customers tell us all the time that their 20 000 led lumens lights seem much brighter than their 40 000 lumen metal halide light.

Therefore when replacing a metal halide light with an led fixture you ll likely need fewer lumens.
