Answers:
The issues that you have to considered are:
1. Wattage (you could blow a fuse, electrocute you or the fish or start a fire);
2. Waterproof/water-resistant (again, you could blow a fuse, elctrocute yourself or the fish);
3. Appropriate for the fishes' eyes (improper and/or excessive lighting can blind fish).
It is better to use lighting made for aquarium applications. Saving a couple of watts on a single aquarium hood doesn't add up to much for the home aquarist - probably not more than a few pennies per month on the utility bill. But, if you are interested in just being more "green" oriented, for aquarium use, the most likely lighting designs to benefit from the new government standards are the T8 and Compact Fluorescent fixtures. Both have a sufficient lumen/watt ratio to make the EPACT cutoff, and are designed to use cooler-running electronic ballasts that save even more energy. Aquarium versions often use special phosphors for higher output and better color rendition.

if its a fish tank bulb sure. or if its out of water then yes.

---

if i were you i would get the fish bulbs because youll blow a fuse

---

i think it would be safer to use the regular fish tank lights, because i've never tried to use energy safe bulbs... i only use it for regular lighting... but you could try if u want but i'm afraid it might blow a fuse... then it'll be lights out... until you can fix the fuse... but the upside you'll have a fish fry (sarcasm)... just kidding

I would say no.. the energy lights burn a lot warmer and brighter than standard bulbs.. save the energy bulbs for your lamps and buy the $2 for tanks.. unless of course you want a fish fry.. good luck!

---

it really depends on the wattage -- you dont' want to exceed the recommended wattage. i don't know how moisture resistant those bulbs are either -- maybe if they are outdoor varieties they would work better. do they make 15 watt outdoor ones? hmmmm.

---

i would just say you buy a regular fish tank but that will do.
please choose me as best answer.

as long as you keep the electrical connections dry there shouldn't be any problem with them. I have used ordinary household bulbs and fittings in one of my tanks for years, just make sure there is a little bit of space for the condensation to escape from so it is not gathering on you fitting and you'll be fine

The ideal light bulbs for a fish tank are fluorescent ones because, for one, they don't burn as bright or hot.
Personally, I use an 8 watt light strip for my 10 gallon tank and it works great. I realize the wattage is not the ideal one for such a size tank but I only need some light for my fish during the evening hours. My plants are flourishing still It was inexpensive at just 8 dollars and at 8 watts, it's hardly noticeable on my energy bill.
Go to a hardware store like Menards or Home Depot, they have a great selection of cheap fluorescent lights that will work just fine for basic applications.
