	How long is long enough for a flourecent bulb?
Klee Banned Posts: 420 Kudos: 307 Votes: 0 Registered: 25-May-2004	I have a variety of plants in my 20 gallon, but recently I've noticed that the backing of the flourecent bulb can become a bit overheated, even if left on for only 2-3 hours. so I'm wondering---how long must I keep my lights on for my plants to benefit but still be able to keep my bulb cool?

The idea is to mimic the tropical, noonday sun and that means the lights should be on for about 10 -12 hours/day. IMO, I prefer 10 hours. If your bulb is heating up so much that you are concerned then there is something wrong, and I'd be replacing the canopy, or checking to see if you might not have the wrong bulb in it. Something is not right if it is truly that hot. Frank -->>> The Confidence of Amateurs, is the Envy of Professionals <<<--
