A fluorescent lamp having a protective polymeric sleeve to provide impact resistance and contain fragments if the lamp shatters. A UV-blocking layer is coated on the outside of the glass envelope of the lamp or on the inside of the sleeve to help protect the polymeric sleeve from UV degradation. The UV-blocking layer includes a UV-blocking component of Al2O3 or ZnO or SiO2 or TiO2 or mixtures thereof.
