I have a 50 gallon tank (36" wide) with a stand and hood I built for it. For the last several years, I have installed two 36" fluorescent tubes to underside of the lid running off of a ballast mounted in the back. I want to convert to LED
and was wondering if anyone had any ideas of some DIY LED
lights I can install the same way. This is a low light planted tank so it has been fine off of the 2 - 25 watt tubes it has been running. I only have 3 inches of clearance between the underside of the hood and the glass at the top of the tank.
