A luminaire (100) has an elongate tubular shell (1) and an elongate internal chassis (2) within the shell dividing space within the shell between a first compartment for electrical components and a second compartment for optical components (7, 6). The luminaire has a sealing cap (3, 4) at each end, and at least one of which supports an auxiliary active component for an application such as emergency lighting or car parking management. The shell (1) has features 1(a) for desired optical properties. The only seals are at the ends, between the end caps and the shell, and these are via sealing rings (17). |
