Refugium Light

[cmantis]

I need a light for my refugium. The space is about 14"x18". This is a rack system so I want to be able to set the shelf above the fuge as low as possible to maximize clearance for the tank above. Can anyone recommend a good light? It can either clip to the side, rest on top (if I put something for it to rest on) or clip to the shelf above it. Thanks.
