It comes in a wide range of wattages from 250 to 1 000.
Metal halide vs led power consumption.
When it comes to power consumption and the power bill led s only save the grower about 15 on the power bill compared to cmh fixtures.
There is a sub category of metal halides called ceramic metal halide cmh grow lights.
Both metal halide and high pressure sodium bulbs are part of the hid family of bulbs.
The average bulb lasts around 6 000 to 15 000 operating hours.
Hence we can remind ourselves that we need to replace the metal halide lights with a certain lumen instead of power.
High pressure sodium vs led what s the difference between high pressure sodium and led lights.
Depending on the particular bulb you might spend around the same amount initially with leds and metal halides.
These are also hid grow lights but they use one or two special cmh bulbs usually 315 watts each.
They are able to produce more lumens with less wattage.
What are led grow lights.
Led can convert 85 to 95 input energy into visible light while metal halide lamp can only turn around 35 to 50 energy to lights majority of energy is wasted as heat loss because of its unique working mechanism.
The heat emissions from metal halides are also much greater than leds which means less energy is directed towards the actual illumination.
Led vs metal halide energy savings now that you understand efficacy hopefully you have a little more insight on how and why leds are energy efficient.
Led equivalents to metal halide lighting offer similar energy savings as over sodium lighting around 50.
When it comes to power consumption and the power bill led s only save the grower about 15 on the power bill compared to cmh fixtures.
However the led grower will use less power for cooling but that savings depends on other factors in the grow space.
Furthermore metal halides are relatively fragile and when broken require special handling because they contain hazardous materials such as mercury.
Which means if you replace a metal halide bulb with an led you ll have a brighter light that also consumes less electricity.
The primary visual difference between them is that metal halide light is white and the light emitted from a high pressure sodium bulb is amber orange.
The lamp works by creating an electric arc through vaporized.
However the led grower will use less power for cooling but that savings depends on other factors in the grow space.
The problem is that over time you will have to purchase a whole lot of metal halides 2 5 to equal the lifespan of a single led.
The additional cost a cmh grower will realize is replacing bulbs.
These lights put out an impressive spectrum of light that replicates natural sunlight better than any light i know of.
Mhs have been used in growing cannabis because they emit a strong blue wavelength which helps the vegetative phase of growth.
Metal halide lights get less efficient when run at less than full operating power.
