hey i found some cheap and light PL lights, decription:
PL light electronic Ballast, 55w, different colours of light avaliable, blue, pink or white and you can mix,
the uncle said that this is for rearing fish and showed me a normal flouresant light(3 tube) set up and said that that was for plants. The description looks the same as the lights that i have now. Anyone know if this is ok? also whats good about blue/pink light?
