Product Overview

This innovative self-test LED emergency downlight cover uses one high-illumination white LED in a 50mm diameter housing. The high output light source together with its low power consumption and built in self-test means it can use a smaller battery pack, giving greater power efficiency and therefore reducing costs. Self-test ensures that the units are always functioning correctly without the need for a maintenance person; if the light is not fully functioning an audio and visual alarm is triggered. The MRDM/ST is suitable for incorporation into emergency lighting systems complying with BS 5266-1:2011.

Please Note: Lighting products available on a lead time are made to order and as such cannot be returned.
