I have shot some fun home movies with the 500T stocks using just the normal household lights. I don't know if the timer had to crank the lights over to the stops to make up for the lower colour temperature of 60W household bulbs. MY home movie modus operandi is to shoot short ends of 16mm in my Filmo, and have the lab make me a "best light" workprint on 3383. I have collected a bunch of Spools and a split reel so I can repack random lengths of film on 100 ft spools. The lab will return the empty spools if you ask to get them back..
