I'm still using these uv sources and still find them good. The smaller one, the 24 watt, is great for setups for hatchlings and tiny torts when the area to be covered is really small.

The 55 watt is the logical step up for a bigger enclosure, at which point there is an option to maybe change to a T5 tube instead which might work out cheaper in some instances. But with this unit there are fewer wires trailing about.
