Q - What is the recommended spacing and/or depth for underwater lights?

A - Many factors will govern the placement or your underwater lights, including the location of a flat mounting surface, the ability to safely run power to the location, and the location of engines, struts, trim tabs, etc. which may obstruct the light output.  Although Lumitec underwater lights can be run above water, they perform best when completely submerged 8" to 16" below the water.  For inboard boats: generally speaking 1 light for every 2.5 to 5 feet of beam provides good results.  For outboard and stern dive vessels, good results are generally acheived by installing lights outboard of engines, and between engines.  For example, a twin engine vessel would use 3 lights, a triple engine vessel would use 4 lights, etc.
