So I contacted ReefBrite n they wanted $119 to repair + shipping, gonna pass on this.
Upon closer inspection, I noticed few of the lights are very dimly lit (only noticeable if u look really close). Don't have a spare ReefBrite power supply to test but I'm thinking the powersupply has gone bad. New ReefBrite 60W ballast/powersupply is $42 on Premium Aquatics... can any electricians out there confirm or give feedback whether they think it's the powersupply/ballast and not the fixture? Otherwise I can buy a used light for $120
