1. The RSC Lightlock is a device which allows moving lights to be rigged on very lightweight hanging or flown structures, thus "counteracting and eliminating" unwanted movement by dampening the motion of automated fixtures.

2. Spelled as two words "light lock" describes an entrance with door doors and often a 90° turn to prevent light intrusion from one area into another. Very often found on entrances to theatres with continental seating and lots of glass in the lobby. See also http://www.pmedarkrooms.com/PME_lightlock.html .
