WOW this little thing puts out some light ! By Agena. push in button for flood, pull button out for spot. Has an attachment screw for attaching to movie cameras?. Couldn't find out much about which movie camera this would go to, or if it attaches to a stand for a movie camera, but It's mighty with a super bright light. This was found in a box of old camera stuff. Measures 2 3/4"L x 3"H x 2 1/4"W. Has a gray metal coating.
