CJK is a fully integrated services contractor, specialising in electrical, mechanical and instrumentation engineering services. Solar AdTek  have engaged them to  install/retrofit our lighting for a number of large projects. These include retrofitting of LED lighting in 1,800 2m2 displays throughout Ireland and retrofitting lighting in 400 advertising displays on the Dublin light rail network (LUAS).

When CJK had a requirement for lighting for their own billboards on their premises, Solar AdTek were their first port of call.

Our solution was to use our bespoke front lit billboard luminaire to illuminate their displays. This billboard lighting reduces energy and maintenance costs. More importantly, it offers a bright, crisp and uniform illumination of the entire posters.

The poster stands out, and with the correct colour rendering, all of the images are clear and clean.
