hi there tbone28,
i recently got a light shop to custom make me an LED array utilising 3w LEDs and they give me great glitter lines though i cant have them turned on for more than 20 mins at a time as theyd overheat. (the reflectors trap heat and i dont run any fans for my T5s.
they are terribly expensive though- to give you an idea, about the price of a new Tunze Nano 6055. but as my tanks packed and i havent added anything to my system for a while, i thought to give it a try.
you can circumvent the heat situation by adding a fan for active cooling though. i opted for a dimmer circuit instead, as i only need them on when im viewing the tank.
perhaps you can pick up an LED torch and shine it down your tank with your main lights on to see if the glitter lines show, then proceed to DIY an LED array similar to the torch if they do?
i think it very much depends on the strength of the LEDs you employ and the depth of your tank. anything deeper than 2 feet and i doubt the glitter lines will be discernable.
cheers,
ian
