UVB Reptile light harmful to warty newt?

[firedreams]

I have purchased a 9 watt UVB bulb for my warty newt, from a local petstore, on the store's advice that this is the appropriate bulb for newts.

The bulb is a 'Desert 50 UVB Florescent': http://www.zilla-rules.com/products/uvb-flourescent-bulbs.htm

The bulb is marked 'for reptiles only'. Reading on the internet, I see that high levels of UVB light can be harmful to newts.

Is this type of bulb safe/appropriate for my warty newt, or should I take it back? What type of bulb would be best?

Here is a link to a lengthy discussion of the risks/benefits of UV light for caudates.

I would say that a low-power UV light would be OK, assuming it's not too close to the surface of the water/island. I would suggest the 2.0, rather than the 5.0 or 10.0 type bulbs. I have no idea where the Desert 50 fits into the usual scheme for classifying the intensity of these bulbs.
