Hi all. I have a 120lyr fluval tank with 2x t8 18w bulbs, not very happy with the yellowish light they show in the tank, and was thinking of changing for t8 leds. I work on a limited budget and find that most of the tubes are £50 plus, which is a little out of my price range. I was wondering if my lighting needs to be aquarium specific or would any t8 leds be ok to use?. Thanks for any replies. Chris.
