A fluorescent lamp (10) having a protective polymeric sleeve (26) to provide impact resistance and contain fragments if the lamp (10) shatters. The sleeve (26) comprises an inner layer (28) of a UV-blocking polymeric material and an adjacent layer (30) of a polymeric material, preferably polycarbonate. The inner layer (28) is preferably a co-polymer comprised of a polycarbonate block and a block comprised of isophthalic acid, terephthalic acid, and resorcinol. The inner layer (28) helps protect the rest of the sleeve (26) from UV degradation. |
