Fitting of downlights is as simple as coring holes through the hollow core of the slab or using a hammer and chisel (recommended chiseling from the underside) to form the required diameter hole to accommodate the downlight.

For suspended or other light fittings, simply drill a hole through the slab and into the slab’s hollow core to fit the electrical wiring through.
Any excessive edge chipping is easily repaired with ‘Rhinolite’ or similar material.

Costs of such electrical light points also become more economical as electrical wires and single light transformers can be placed into the horizontal hollow cores of the slabs the day after installation, instead of the traditional light boxes and conduits.
