A fire rated downlight is constructed to withstand exposure to a fire within certain time limits for the purpose of maintaining the integrity of the ceiling and thus keeping the fire from spreading to other areas of the structure. The implementation of this crucial feature has been driven by some legislative building regulations. The UK Building Regulations establish within Approved Document B that “the building shall be designed and constructed so that, in the event of fire, its stability will be maintained for a reasonable period”, “the roof of the building shall adequately resist the spread of fire over the roof”, and “if a fire separating element is to be effective, then every joint, or imperfection of fit, or opening to allow services to pass through the element, should be adequately protected by sealing or fire-stopping so that the fire resistance of the element is not impaired.”
