The other half is mostly in the near-infrared part, with some in the ultraviolet part of the spectrum. Solar radiation having wavelength less than 0.286nm (called ultraviolet) is absorbed by ozone layer in stratosphere.

An Introduction to Fluorescence Spectroscopy

To account adequately for the processes of absorption and emission of light, it is necessary to assume that radiant energy can only be absorbed in definite units, or quanta.
Safety Tips for Using UV Lamps - Berkeley Lab
www2.lbl.govUV lamps produce light radiation from ultraviolet through visible to infrared radiation. The biggest hazard comes from the UVR. UVR cannot be seen and is not felt immediately, but it is harmful to both the eyes and skin. The user may not realize the danger until after the exposure has caused damage. Symptoms can occur 4 to 24 hours after exposure.
