Safety in explosive atmospheres enhanced. Retainer for floodlight designed to undergo relatively small temperature rise. Reaches no more than 350 degrees F (177 degrees C) with lamp operating at about 4,700 degrees F (2,600 degrees C). Satisfies 352 degrees F (188 degrees C) requirement for operation in some explosive atmospheres. Made of thermally conductive metal with coating of material having low thermal absorptivity/emissivity ratio so it conducts heat away from lamp and radiates to surroundings efficiently.
