摘要: A fluorescent lamp highly capable of inhibiting penetration of mercury or ultraviolet ray, in which blackening of a glass tube is prevented, and which displays excellent luminous flux maintenance. The lamp has a protective film mainly composed of substantially spherical metal oxide particles, which is formed between a glass tube and a fluorescent layer on the inner surface of the glass tube.
