Building Regulations Part B, C & E compliance can be a major issue when installing fire rated downlighters with LED lamps due to the various materials used in LED lamps. Traditional halogen lamps made with glass are fully enclosed and maintain integrity in the event of a fire, but LED lamps made from other materials may allow air and heat to pass through the fitting. In response to this we have upgraded our wiring, can and lamp holder and made it fully enclosed, making it one of the first of its kind to be fully compliant with the regulations, irrespective of the choice of lamp.
