For sale is a Beautiful Norman Model 4000PS Flash / Strobe Power Supply and Norman LH4000 Bi-Tube Lamp-head with Built-In Blower. Included with this listing is the 120V, single-phase AC power cord and the Sync-cord with firing push-button. NOTE: I have tested this system and found everything to be in working order (see photo's).

This system also comes with a padded wood crate for the lamp-head and cords. Serial No.138170. ' I removed the outer part of the flange that was being used to mount the light.
