LUMAWISE Power Input Terminal Block (TB) TE Connectivity's LUMAWISE Power Input Terminal Block (TB) offers a unique, highly engineered wire termination alternative to traditional terminal blocks utilised in LED outdoor lighting luminaires and HID (high-intensity discharge) luminaires. This includes HPS (high-pressure sodium) and MHL (metal halide lamps), which are rapidly transitioning to LED luminaires. The innovative design replaces power entry aluminium lug screw connections with rising vice clamp screw connections. Quick-connect tabs and receptacle wire connections are replaced with lever-actuated spring cage clamp poke-in wire connections.
