Hey, just recently, I was forced to toss out the tank light I've had for at least a decade, decade and a half, which was lighting up my 10 gallon tank, which is 21 years old, and right now the hardest part is finding the right size tank light, along with a new hood, since the current one is going to be tossed out next. Anyway, the only place to buy anything fish related where I live is the local Walmart, and the only thing they have is a LED hood, where the light is built into the hood, but the only thing keeping me from buying it is, besides being broke, is that I have a power filter and heater hanging out on top of the tank, and I'm not sure if that type of hood would allow me to put holes on it to make room, or stick to the basic kind, where the hood has a lid that opens, and the regular light that requires you to change the bulb. And before anybody asks, I also have a 20 gallon tank, and right now, going use the light for that to pull off double duty for both tanks.
