Bolex 18-5L
The Bolex 18-5L is a Swiss-made Super 8 silent projector, introduced in 1967 as an updated version of the earlier 18-5. It projects forward at 18 and 5 frames per second, runs in reverse at 18fps, and has a rapid motor rewind. The lamp switches off automatically during reverse and rewind. It takes reels up to 400 ft on folding reel arms.
Owners on the 8mm Forum consistently describe it as a lovely, compact, beautifully engineered machine - sturdy, quiet, and with a very steady picture. The cast-aluminium body and Bolex's generously rated transformer contribute to that reputation. One quirk to watch for: the projector uses a lamp with an unusual base design that can be hard to source today, though compatible CXR lamps are still available. The original lamp is rated up to 75W. Some owners report successfully running 100W lamps thanks to the transformer's headroom, but 75W lamps are still readily available, and 100W is an unnecessary risk to an old valuable machine.
Another practical note from the 8mm Forum: the power lead includes a ground/earth connection, and you need the correct Bolex lead to keep that ground. Improvised cords with unshielded connectors have turned up on second-hand units, and they are dangerous. The North American version uses a 2-prong outlet, and owners have successfully adapted standard 2-prong cords with a bit of persuasion.
Documentation on this model is thin. No original price, weight, or detailed technical specs have surfaced. The serial number is stamped on the bottom of the base, behind the front leg, and can be used to date the unit. Bolex catalogs from 1970 offered a choice between two versions of the projector, apparently for a short time, but the exact distinction isn't well recorded.
