Which is better LED or fluorescent?

LED bulbs are also more durable than fluorescent bulbs due to their compact size.
Can you interchange T8 and T12 bulbs?
As far as safety is concerned, you can exchange them. If you place T12 tubes in a fixture with a T8 ballast, you will wear out the ballast and have to replace it. If you place T8 tubes in a fixture with a T12 ballast, then the tubes will have a shorter life due to a higher current through the tube.

Is T5 or T8 better for bearded dragons?
In my opinion, the T5 is vastly superior – it has a much higher UVB output and can be placed 12″ to 18″ away from your bearded dragon. T8 bulbs, on the other hand, should be placed within 8″ of your Bearded Dragon. Since UVB output is much lower in T8 fixtures, the bulb must be placed inside of the tank.

Basically, T8 = 1 inch diameter, T10 = 1.25″, and T12 = 1.5″ diameter. Measure across one of the ends of the bulb you are replacing to see what yours is.
