Mhs have been used in growing cannabis because they emit a strong blue wavelength which helps the vegetative phase of growth.
Metal halide lights vs led.
Studies have shown that the blue wavelength in light increases the overall growth of plants.
Led theoretically because of the nature of how they produce light led technology is superior to any hid technology because it can target as necessary any part of the photosynthetic response spectrum specifically without outputting under utilized light and wasting energy.
Led vs metal halide what are leds.
I strongly suggest freshwater plant and reef keepers read this in depth and more importantly well researched and current article about aquarium lighting.
Not only are they more efficient than incandescent lights but they also burn much brighter.
It comes in a wide range of wattages from 250 to 1 000.
Before we breakdown the contenders let s talk about the current reigning champion.
Until a few years ago there was a huge misconception that led lighting was not a good replacement for traditional metal halide lighting.
Led vs metal halide high bay understanding the advantages of led high bay over metal halide high bay in a detailed comparison.
In this case we ll be comparing leds and metal halides but all bulb types can be quantified with this measurement.
For those who have yet to discover the beauty of the led led bulbs are light emitting diodes where electricity flows through two electrodes an anode and a cathode.
Correlated color temperature read more here.
Industrial led lighting for factories warehouses and more.
Led light is focused while metal halide light is not.
Efficacy is a measurement of how well a light source produces light.
While this was true back in the 1970s when led technology was still in the early stages of development it is no longer the case.
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.
Metal halide lights are very bright when new but lose their lumens very quickly.
Metal halide lamps generate a very cool white light.
In the picture to the left a 12 watt led grow light similar to the natural daylight led aquarium light showed superior growth to a 175 watt full spectrum metal halide.
Metal halide mh metal halide is a hid style grow light.
