A downlight is a light that has been recessed into a ceiling that throws light downwards in a narrow beam.
Using downlights rather than pendant or fluorescent fittings will mean you need to install more lights, resulting in higher energy use and running costs. Should you need to use downlights, LEDs – or light emitting diodes – are more efficient to run. A range of low-energy downlight fittings that use compact fluorescent lamps (CFLs) or LEDs rather than halogens are now available.
Because downlights are recessed, the heat they generate goes into the ceiling space. For this reason, electrical and fire safety regulations require an adequate clearance between downlight fittings and insulation, as well as other combustible materials like timber.
If you have multiple downlight fittings in your home, the insulation gap around the fittings will decrease the effectiveness of your home's ceiling insulation, increasing your heating, cooling and lighting costs.
(LED) and compact fluorescent lamp (CFL) downlights don't give off as much heat as halogen downlights and are far more energy efficient.
