It comes with a ceiling hook up assembly kit. Your saying its better to hook it up to the ceiling and increase the hight? Im sure regardleas it wont matter much considering the power these things got
correct. When I spoke to Jeremy about this, the conversation had been prefaced on the fact that I have to mount my light on the tank which is what led to the comment about the tight beam. Hanging this fixture will certainly provide more coverage, and the cree emmitters put out plenty of light. Even at 18" above the tank Im sure its got more than enough output. I doubt that anyone using this light for a planted application will need to run them at 100%.
