are great lights with leds you dont have to replace the leds they are cheaper to run and lower heat. Mh
unless you have a pretty decent ballast then you maybe replacing it a couple time as well as buying new bulbs once or twice a year. alot of people have used leds and loved them and some hate them this goes with everything in this hobby people hate what some people love. Idk if id say that they arnt for begineers, the only thing I could thing of is bc you may burn your coral up. Thats an easy fix just light acclimate everything like your suppose to with every light. If you have a 55 gal
its only a foot wide, idk if 6 bulb t5 will fit it may be to big. You have to think about getting into your tank when you lights on. I wpuldnt want to have tp take my light off every time I need to feed them. Mh
yes leds yes. Leds is the future I think in aquariun lighting, even though I seen some more movement in the mh
. the 55 isnt a real deep tank either will work mh
is going to give off more heat and you may need a chiller or something to get rid of the heat let off like a computer fan. With the mh
you have to be careful when changing the bulbs bc if you let then burn out and theres a big spectrum difference when you add the new bulbs you may destroy your coral. So if you go mh
make sure change them any where between 6 to 8 months so this is less likely to happen to your coral.
