Downlights become hot when switched on
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. Always follow manufacturer and safety regulations and consult a professional where necessary.
Downlights can affect your insulation
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 CFL downlights
(LED) and compact fluorescent lamp (CFL) downlights don't give off as much heat as halogen downlights and are far more energy efficient.
