The lighting is of very good quality very sturdy very strong. They are preset channels that are easy to use you can also operate the light manually I used a par metre I can easily grow SPS and LPS corals with these lights. They are amazing value for money in comparison to Biggar brand names. I Highly recommend them you will not regret it. I have had many sets of lights in the past none of them stack up to these in comparison yes you can get lights as good quality but you will pay a hell of a lot more money for those it's simply not worth it get these ones and you're laughing. Once I have set up my aquarium completely I will upload some photos.
Really great set of lights. Easy to setup and assemble, give off a great light, corals look great and growing well. Only thing is it has an EU plug which wasn’t advertised, but with an adapter it’s no problem . Can’t comment on reliability, will update if I have any problems.
