Using LED lamps as replacements for conventional lamps in hazardous area light fittings

The use of LED lamps as replacements for conventional lamps in hazardous area ‘Ex’ fittings will invalidate the certification of the fittings. Unless the fittings have been certified for LED lamps, replacing the lamps with LED ones may make the fittings electrically unsafe.

Changing the internal wiring in fluorescent light fittings to accommodate LED lamps will also require recertification of the fittings. This should only be carried out in a certified overhaul facility, and in accordance with manufacturer’s instructions.

Likewise changing the type of lamps in emergency lighting fittings can make the fittings no longer suitable for purpose.

In some cases the simple replacement of a fluorescent tube with an LED lamp can make the light fitting electrically unsafe, for instance if the modified fitting then permits access to live parts.

Electrical workers should note that it is important to ensure the use of LED lamps as replacements in conventional fittings is consistent with the certification of the fittings.
