I just recently purchased two 18" Acan Prism LED lights. So far I'm really liking them although they're not near as bright as my old Chinese led 48" light. Although I think that light may have been too bright. Anyways I was wondering who here owns the acan lights and what you have your settings at? Along with what you're growing and how far above the water you have the lights, And do you use the Lunar or lighting cycles and what settings?
