I have several of the Lowe's shop lights. Have used them for years for general lighting. I recently began using one for my 29 gallon tank until I can get the money to order a T5 light. I use the daylight bulbs (6500k) bulbs and have it mounted 5 inches above my water line. It is bright. When I have it on I don't need to turn my room light on. According to the light chart everyone has recommended to follow it gives me low light. I included the chart in my post. My plants are doing better. My java fern, money wort, and ludwigia at least. My penny wort has almost all died. Of course the fish keep pulling the leaves off of it so that probably is what is killing it.
