i have no problem getting a new fixture. the only reason i got this one was because it was cheap but if i need to get a new fixture or there is any other light that would work i have no problem buying it. i found a LED bulb: ecoexotic PAR38 LED lamp 18 watt (6 blue, 4 white, 2 red). dont know much about LED lights and not sure if it would be to strong for such a small tank
