We had two solar tubes with light add-on kits installed by Brisbane Daylight Systems in our hallway and walk-in robe as these two areas were always dark and gloomy. The difference since the installation is amazing! Our hallway and WIR are now well lit and we no longer have to switch lights on during the day - brilliant as I was constantly telling the kids to "turn off the light"! The service from start to finish was friendly, professional, and hassle-free. I would happily recommend this service to anyone thinking about brightening up their interior.
