LEDs produce a lot of heat and can degrade or fail well under their expected life unless this heat is conducted away from the LED chip and sensitive driver electronic components. Domestic downlights face an even bigger challenge when covered by thermal insulation which prevents the heat from being convected away above the fitting.
LED downlights may be classified as IC and tested safe to cover with thermal insulation, but this rating is a safety rating for the prevention of fire and not a means of ensuring the ambient running temperature will remain low enough to ensure the electronics will last their rated life. By lowering operating temperatures, LEDs and drivers are sure to achieve target longevity and give you years of trouble-free operation and genuine customer satisfaction.
The new Superlux LDL downlights solve this problem, by conducting heat from the LED mounting surface as well as the electronics enclosure down off of the fitting turning the decorative aluminum trim that sits below the ceiling into a cleverly disguised heat-sink.
Because the new LDL downlights have enclosed bodies and built-in diffusers they do not allow dust to get inside and reduce light output or compromise the ceiling thermal barrier.
The LDL 125, LDL 100 and LDL 80 downlights have similar light outputs to 100, 75 and 35 watt incandescent downlights despite using only 8 W, 5.5 W and
3.5 W respectively.
The LDL fixed downlights have a warm 3000K colour temperature and soft lighting appearance due to the integral diffuser which shows no hot spots from the multiple LEDs across its surface. The diffuser provides a uniform low-glare 60° beam, but with a soft cut-off that delivers light above and beyond the 60° much like the light distribution people are used to from incandescent fittings.
