One wire, one job: linking your light bars
The TRPFEXT accessory covers the linking needs of a Tri-Proof installation. Because Interior and Exterior Tri-Proof LED light bars have an internal transformer, they connect directly to a 100 to 277V AC supply — there is no external driver to hide above the ceiling and nothing extra to mount. The waterproof connector wire is the link cable that carries power from one bar to the next so a whole row lights up from a single connection.
Sealed connections built for damp places
What makes this part different from an ordinary extension lead is the sealed, weatherproof connection at each end. Tri-Proof fixtures are chosen precisely because dust, splashes and humidity are part of the environment, and the wiring between them has to hold up to the same conditions. The waterproof connector wire keeps that protection intact through every joint of the run, so you are not creating a weak point at each fixture. That matters in a wash bay where water is sprayed daily, in an unheated shed that swings from humid to freezing, or in a parking garage where road salt and condensation are a fact of life.

Planning your run
Start by mapping where each bar will sit. The 15 cm connector wire is the one to use when fixtures are mounted nose to tail in a continuous line — it keeps the cable tucked away with no loops hanging down. Remember the limit of 15 bars in series on one feed: on bigger projects, split the space into sections and give each section its own feed. The clips supplied with the light bars handle the mechanical mounting on ceilings and walls, indoors or out, so the wires only have to deal with the electrical side.
Where it earns its keep
Think garden sheds, home garages and workshops, car washes, service bays, agricultural buildings, storage rooms, loading docks and commercial or industrial spaces where a wet or damp location rating is non-negotiable. A long warehouse aisle can be built out in sections of bars chained together, each section fed cleanly and independently. As with any hard-wired connection to a 100 to 277V AC circuit, have the supply connection made by a qualified electrician according to local code. Order what your layout calls for, and your Tri-Proof LED light bar project goes up in an afternoon instead of a weekend.
