The arrival of a new light source, the BBT scialytic, which projects a beam of light without cast shadows, has made it suitable for marine spotlights. The protective glass has been replaced by magnifying glass. How many are left with their original beam? In 50 years in China, I've never found one like it....Mounted on an early 20th century "HENRY" wheeled stand, with a 360° swivel and 60 cm ascending tube, very stable, I electrified it with a hemp rope cable mounted on a dimmer switch.I'll let you appreciate all the details in photos...enjoy!
