LED FAILURE DUE TO BAD DESIGN
LEDs are particularly well suited for use in emergency lighting gear as they have a high lumen efficacy and are not damaged by running at low powers, unlike fluorescent lamps. However, they can soon be destroyed by poor emergency drivers.

NON-COMPLIANT ENCLOSURES
We have noticed that some of our customers fit remote emergency packs into flimsy enclosures. This can be dangerous and this type of enclosure is illegal where mains voltages are present.
