800 gallon reef tank with mh and led lighting dave burr talks about where we re at with our mh vs.
Led vs metal halide reef lighting.
Before we breakdown the contenders let s talk about the current reigning champion.
Metal halide hqi lighting is nearing the end of its reign over marine reef aquariums.
Efficacy lumens watt led vs metal halide.
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.
Many years ago metal halide lighting was necessary for lighting deep marine reef aquariums especially if they were dominated by sps corals.
Metal halide new to the hobby reef central online community general interest forums new to the hobby.
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.
At only 2 5 tall the 150 watt bulb provides full spectrum light suitable for corals and other reef builders.
I strongly suggest freshwater plant and reef keepers read this in depth and more importantly well researched and current article about aquarium lighting.

You can hang the light above your tank or use the arm kit.
Reef brite products are perfectly matched to meet the demands of the discriminating aquarist the reef brite halide hybrid features a specially designed aluminum reflector which maximizes light transmission while controlling proper lamp temperature for optimal lamp performance complete with xho high power led supplemental lighting.
In this case we ll be comparing leds and metal halides but all bulb types can be quantified with this measurement.
In exchange for the intensity needed to grow sps corals negative factors are also included.
