:yea its better then nothing, make sure its not too cold or too hot though, and DO NOT put it in a glass container, tubawear would be best, make sure he can retreat to shade though. Get a UVB bulb though! A powersun is recomended if you have a large enclosure.
Rick:: In my opinion, taking your Waterdragon outside is a thousand times better then any artifical lighting. Artifical lighting does a poor job of creating the UVB spectrum needed for D3 synthesis. In most cases the animal has to be within 12 inch of the light source for any effect at all and in time the bulbs spectrum degrades rendering it useless. Unless you plan on buying a light meter and monitoring your bulbs or routinely changing them every three to six months, you are better of with a dietary calcium/D3 suppliment and/or natural sunlight. There are many people who have depended on these lights only to find that their lizards get D3 imbalances anyway. I know that people will argue with me that some lights are better then others, but I don't think that saying natural sunlight is the best method can be contested.
