I do not think that will be sufficient for the entire growth of the plant particularly with that reflector.
UV lamps are also generally produced for sunbathing, and I would imagine can burn your crops, unless kept far away, in which case they will stretch.
They may not be of the correct wavelength either, as I have not seen these used in a grow before.
Good luck...
For a safe and sure bet, go out to the store and buy a few CFLs. They should do you good!
