Will a 24 inch T5 ReptiSun bulb work for a 4x2x2 enclosure?

Buying a whole new fixture+bulb seems so expensive.. I think I read that your uvb bulb should cover at least half of the enclosure, is this true?

It should cover 3/5 of the tank to give enough space if they want to get away from the rays. I have a 36inch viv with a 24inch bulb. L I think you should go for a 30

I use 24" fixtures in my two Zens they are a 4x2x2 and they work fine --- you do not need a 30 " unless you want to -- you dont want your dragon hiding from the UVB ---
