UV light is mostly harmful to plants!
Here's a little article on lighting, but if you scroll down near the bottom, it gives a chart about how different wavelengths of light affect plant growth.

You will see that the deepest into UV range, UV C is toxic, UV B is harmful, UVA (closest to blue) is not harmful, but not beneficial.
UV lights are used in pond filters to kill algae and other little plants that would otherwise grow in the pond! Stick to the regular fluorescents.

2 rainbowgardener - I'm not sure but I think the Op meant UVA UVB light's. There are THE UV light's that ponders use (I fore went that with my own pond because I wanted a natural pond and my koi LOVED eating algae then there are the UVA/UVB bulbs that I use for my reptiles. They need it to use the calcium they need, I also surround their tanks with my house plants and ohhhhh boy, I'll have to snap a picture for you. My oak leaf plant LOVES that light. It literally presses it's leaves up against all sides of the glass to get closer to the light! Then you also have the Gro light's that most people use for.... ehhh hem indoor cultivation of .... well here it's legal if you have a prescription allowing you to grow your own.... ummm let's just call it mary. I would think twice about useing man made sun light thought, those bulbs are so pricy! The ones I use for my reptiles are at LEAST 35 dollars a bulb not including the lamp. The grow one's can run atleast 200 dollars... used.
