That light is too powerful. You may want to get something like this http://www.ebay.com/itm/111156677896...84.m1439.l2649

or use a CFL bulb with reflector.

If you want to go with LED's - you will need roughly 2 to 3 Watts of LED light for every 8 sq. Inches of waterfall scrubber screen.

For example a screen 4 X 5 inches would be 20 sq. inches and need 3 - 3 Watt LED's spread out or a spotlight such as in the link of 10 Watts.

I have one of these 20 Watt spotlights lighting a screen that is 5" X 8" that is doing very well.
