A lighting unit comprises a cartridge 2 retaining a double ended strip light 4, and a cartridge holder 6. The cartridge 2 has terminals (not shown) projecting at one end for engagement in supply socket openings 54 of the holder. The holder is secured to, for example, a wall and the cartridge is engaged with the holder as follows: Projections (not shown) provided on the inside of the cartridge are engaged in slots 30 formed in the holder. The cartridge may then be slid along the holder to its installed position and the terminals thereby engage within the socket openings 54. Elements may be safely replaced because all live terminals are shielded from touch. |
