UV A/B is oxidizing, which is why plastics left outside degrade rapidly, discoloration occurs, etc. It's bad for your eyes, bad for your skin in excess, and creates ozone in the air which is an environmental pollutant. Normal indoor plants have no need for UV at all. Nor do most food plants -- greenhouse glass blocks UV, for instance.
