Abstract: Solar light redirecting glazing units include light redirecting and light diffusing constructions. The solar light redirecting glazing units may include a glazing substrate, a visible light diffusing layer, and a light redirecting layer oriented such that incoming solar light contacts the visible light diffusing layer before contacting the light redirecting layer. The solar light redirecting glazing units may include a glazing substrate, a patterned visible light diffusing layer, and a light redirecting layer. The solar light redirecting glazing units may include two glazing substrates separated by an intervening space with a solar light redirecting layer disposed on one glazing substrate, and a visible light diffusing layer disposed on the other glazing substrate.

Abstract: A portable lighting system including a light housing carrying at least one light emitter and a power source powering at least one light emitter. At least one portion of an interface is disposed on the light housing for securing an attachment having a corresponding mating portion of the interface. The interface includes a male portion having multiple protrusions and a female portion configured to receive and releasably retain the corresponding protrusions of the male portion. In another aspect, the interface for releasably secures a fastener to an attachment. At least one portion of the interface is disposed on the attachment and at least one mating portion of the interface is disposed on the fastener.
