With this in mind let us look at the luminous efficacy of a metal halide lamp versus that of a led lamp.
Metal halide vs led wattage.
In the above example we compared a 400 w metal halide bulb with a 150 w led retrofit kit.

These are big lights typically used in large areas or sports lights like basketball court lights.
Led metal halide equivalent when replacing metal halide lamps with led lamps the equivalent sizes of lamps are as shown.
Mhs have been used in growing cannabis because they emit a strong blue wavelength which helps the vegetative phase of growth.
Both metal halides and leds are considered to be more energy efficient than incandescent lamps.
Led vs metal halide wattage conversion chart.
A 400 watt metal halide bulb consumes about 455 watts of electricity.
While the light may seem very efficient it falls short when pitted against a led light because there are leds that emit as many as 200 lumens per watt.
Led long high bay.
But metal halides cannot work without ballasts and ballasts also draw a small amount of electricity approximately 15.
A new 400 watt metal halide lamp is rated to last up to 20 000 hours.
A metal halide light that produces 30 000 lumens discharges 75 lumens per watt.
It comes in a wide range of wattages from 250 to 1 000.
Existing lighting current wattage of bulbs.
This shows that a much smaller watt sized led lamp can replace a larger metal halide lamp.
We call that a win win.
Studies have shown that the blue wavelength in light increases the overall growth of plants.
Currently we are seeing the following.
There are also other things you need to be aware of.
Which means if you replace a metal halide bulb with an led you ll have a brighter light that also consumes less electricity.
You will need about 70 000 to 80 000 lumens.
Now led s have changed the game as an led bulb the uses 15 watts is no way similar to a 15 watts incandescent nbsp nowadays companies rate bulbs through lumens as these give you a more accurate indication of how much light to expect from an led metal halide high pressure sodium to led wattages conversionoriginal lampled lamp70 watt metal halide30 watt led100 watt metal halide40 50 watt led150 watt metal halide60 70 watt led175 watt metal halide80 90 watt led70 watt high pressure.
