Metal Halide Lights Vs Led

Efficacy is a measurement of how well a light source produces light.

Metal halide lights vs led. 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. In this case we ll be comparing leds and metal halides but all bulb types can be quantified with this measurement. With led lighting no lumens are lost because of reflection you need fewer led lumens than metal halide lumens to get the same amount of light it s a matter of quality over quantity. Mhs have been used in growing cannabis because they emit a strong blue wavelength which helps the vegetative phase of growth.

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. Efficacy lumens watt led vs metal halide. Metal halide lights are very bright when new but lose their lumens very quickly. Until a few years ago there was a huge misconception that led lighting was not a good replacement for traditional metal halide lighting.

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. Studies have shown that the blue wavelength in light increases the overall growth of plants. I strongly suggest freshwater plant and reef keepers read this in depth and more importantly well researched and current article about aquarium lighting. 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.

Correlated color temperature read more here. 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. Led light is focused while metal halide light is not. Led vs metal halide high bay understanding the advantages of led high bay over metal halide high bay in a detailed comparison.

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. Metal halide mh metal halide is a hid style grow light.

For decades metal halide lights were said to be one of the best lighting options around.
