Abstract: A reel based tensioning device includes a housing, a spool that is rotatably positioned within the housing, and a knob member that is operably coupled with the spool to cause the spool to rotate in a first direction within the housing and thereby wind a tension member about the spool. The reel based tensioning device also includes a load holding mechanism that is coupled with the spool and that is configured to rotate the spool in the first direction within the housing and to prevent rotation of the spool in a second direction to prevent unwinding of the tension member from about the spool. The reel based tensioning device further includes an audible component that is configured to produce an audible noise responsive to operation of the knob member to signal an adjustment of the tension member.

Abstract: A luminaire can include a power source housing that houses at least one light fixture component. The luminaire can also include a light engine tray disposed proximate to the power source housing. The luminaire further can include a first acoustic feature coupled to the power source housing and the light engine tray, where the first acoustic feature comprises a first side wall having a first configuration, where the first configuration of the first side wall absorbs sound.
