Flashlight Only

Can I use a torch light for a beta and three neons if only for a few hours a day?

It hangs so no direct the tank is as close to it, but it lights the whole platform.

Yes, but ecologically speaking (and possibly financially), running through batteries like that is not the most prudent thing to do. The lanterns are intended for portable, intermittent. You'll spend quite a week or two in the batteries could have bought a small fluorescent lamp that performs as well or even better.
