Abstract: Devices and methods for assessing topography of a reflective surface are provided. The methods comprise directing an arrayed light source onto the reflective surface to produce a reflected light pattern; and observing the reflected light pattern without the use of a computer to detect the presence of one or more topographical features of the reflective surface. The devices comprise an arrayed light source and a portable support operatively connected to the arrayed light source by an adjusting element. The presence of one or more topographical features of the reflective surface to are noted by an observer without the use of a computer. Defects may be discerned by the presence of a swirl in a reflected light pattern.

Abstract: Described is an overhead lighting device (10) that slides on a track (12) that may be continuous and has a releasable brake (20). A light bar (14) comprising a plurality of light sources (16) is in movable contact with the track (12). The releasable brake (20) has a first position that locks the light bar (14) in place and a second position that allows the light bar (14) to move freely. The light bar (14) may move from a position parallel to the track (12) to a hinged position that allows a user to position the light bar (14) as much as perpendicular to the track. Members (32) to mount the device (10) are flexible to facilitate packaging and shipping of the device (10), where the members (32) are sleeved (34) with a material that can be made rigid upon installation by, for example, the use of resin-impregnated materials such as knit fiberglass, foam, or cloth or the use of thermoset plastics.
