Abstract: A light fixture mounting assembly that includes a lamp housing having a sidewall and an opening defined by a rim at one end of the sidewall and a detent extending outward from the sidewall in a position to engage an outer surface of a panel when the housing is in an installed position. A lamp module is carried within the lamp housing and comprises a lamp positioned to emit light through the housing opening. The lamp housing is configured to carry either a spring clip-type retainer or a hose clamp-type retainer to hold the lamp housing in the installed position.

Abstract: An elevator ventilation fan assembly for hazardous operating environments and comprising a fan disposed within an enclosure to be carried on an elevator cab roof. The fan may be suspended by a fan support framework from at least three non-co-linear suspension locations of the enclosure lid. The assembly may include a vibration isolation element disposed between the fan motor and the enclosure lid, a cover panel supported by a cover support framework on the enclosure lid, a fan guard screen carried by the enclosure lid, a fan motor junction box carried within the enclosure by the lid and accessible via a removable side panel of the enclosure, and/or a fan duct surrounding the fan.
