I have a rack with six 24*12*15 tanks which are currently lit with individual 20w led spotlights. I would like to build a light using LED strips running the length of the tanks ie 6ft. (the tanks are end on in the rack). The light frame would be about 6 inches above the tanks. While I don't need hugely powerful lights, all these tanks are planted so light must be decent. While I'd enjoy playing with the colour changing strips they may not be able to give me enough, or the right type of light. I'm thinking I probably need more than one strip so I could use a combination of colour types. What should I be looking for? Any advice will be gratefully received.
