Submitted by an anonymous contributor. Sometimes a SM works in a situation where the lighting designer doesn't come in until a week before the show opens, and the technicians don't come in until the night before tech to hang the show. In such situations, it behooves the SM to know what the physical lighting situation really is well before they arrive. If the venue rented your production company 100 instruments but only 75 are in working order, you may have severe lighting problems that can't be fixed in the few days that the lighting designer and technicians have to open the show. So the SM inventories the lights, lets the producer know what the problems are, then hands the schedule over to the lighting designer and technicians when they arrive.
The MS version is Word with an Excel chart inside. PDF version included as well.
