Many of these classic lanterns are still in use. To bring them up to date in terms of health and safety, the wiring should be completely replaced, a safety bond should be used between the barndoor and the main lantern, and ideally a microswitch should be used to isolate the power when the front lens is opened. Because of the easy access to live terminals when the lens is opened, this lantern should not be used in schools unless it's been modified to isolate power.
A lensless 1000W Patt.743 was used in the London production of The Lord of the Rings as a backlight (to cast shadows) on the Last Battle sequence. (2006-2008)
