I contacted Lumitec because I am torn between the all blue underwater lights or the blue/white. When I asked about the brightness they told me the dual color only has full brightness when both colors are on and half when blue or white only is on. Makes sense but with out a Lumen measurement that’s not much help - I have asked. I would think that the all blue full out put may not be as bright as the blue white together, because of the white. I could be wrong and half blue or half white may be bright enough - and the full output both blue and white a bonus. Or maybe half the LEDs not enough and relatively useless. ??? I boat in NE waters primarily and have a big platform, putting two lights on aft port and Starboard sides and four on the transom. SeablazeX. Anyone have any experience?
