I'm just wiring a mass of fluorescent strip lights into my workshop today but I find it's actually no good for jobs where you need to spot bumps and hollows cos it bounces cold white light around the room and you get no decent shadows. On the other hand the Mark 1 Sun, especially when low, throws great shadows.
Try a vertically mounted tube at some distance beyond the bench. The vertical bar of light gets reflected in the wet surface and 'hey presto' all waves, ripples etc are revealed.
