Integral rethinks the fire design of downlights
Integral LED has overhauled the fire-rated downright by re-engineering it to take advantage of the features of LEDs. Many of the features of conventional fire-rated downlights have been stripped away to exploit the advantages that LEDs provide. The result is a product that dispenses with the need of a ‘can’ to preserve fire safety.
Installing a downlight involves cutting a hole in the ceiling, which compromises fire integrity. It is important to understand that it is not the downright itself that is subject to fire rating, but how long the complete barrier can withstand a fire.
The Integral Evofire involves the creation of a glass and steel barrier to provide fire protection below the lamp at the ceiling surface. The resulting lightweight downlight is rated BS 476 and matches current fire regulations. The product prevents smoke and flames entering the ceiling void — extending escape time in the event of an emergency.
Under test conditions, lamps ran up to 10 K cooler than a typical model using a can, potentially doubling the life.
The design has been tested by a UKAS-accredited fire laboratory for 30/60/90 minutes in a full furnace.
