Abstract: A light fixture includes a lighting module and a ballast. The ballast includes a housing and a power module. The housing includes a front cover and a rear cover. The front cover includes a front wall and upper fins and lower fins that extend from the front wall. The rear cover includes a rear wall and first fins and second fins that extend from the rear wall. The power module includes a plurality of heat generating semiconductor components that are thermally coupled with the rear wall to facilitate cooling thereof.

Abstract: A heater includes an enclosure, a first baffle plate, and a second baffle plate. The enclosure includes a first wall, a second wall opposite the first wall, and a top plate extending between the first wall and the second wall and cooperating with the first wall and the second wall to at least partially define an interior. The heating module is coupled with the enclosure and is disposed beneath the first baffle plate and the second baffle plate. The heater can additionally or alternatively include an air quality monitoring system and an isolation transformer. The air quality monitoring system includes an air quality controller, at least one air quality sensor, and a power input. The isolation transformer is configured to deliver power from the air quality monitoring system to a fuel system controller of the heating module to facilitate powering thereof.

Abstract: A light fixture includes a housing, and a lighting module. The housing defines first and second portions. The second portion defines a window. The lighting module is at least partially disposed in the second portion. The lighting module includes a submount, a plurality of light emitting diodes, a lens cover, and an encapsulating material. The plurality of light emitting diodes is coupled with the submount and is configured to project light through the window. The lens cover includes an exterior surface and overlies the plurality of light emitting diodes and the submount such that the lens cover and the submount define an interior therebetween. The encapsulating material substantially fills the interior.
