Just added another light to my 30 gallon and went with the nicrew based on several recommendations in the past, here is it compared to the beamworks da6500 i already had for it. First picture is both, second is nicrew only, last picture is beamworks only. Nicrew seems much much dimmer than the beamworks and doent actually seem to make it much brighter than just beamworks alone but if my dwarf baby tears finally start carpeting i guess ill know its enough additional to acheive my goal. Anyway if you are poor like me and looking for a budget light i think beamworks is the better buy for a little more money and ive had good results with just it.
