Sirius LED Illuminator

Fiberstars EFO Harness Adaptor

Fiberstars compatibility with UFO quality!

If you are one of the many people who have, in the past, purchased a fiber optic harness for use with a Fiberstars EFO-1+1 or EFO-AG illuminator, you may know that it is now virtually impossible to purchase a compatible, replacement illuminator.

With the EFO adaptor from UFO, your search is at an end!

Simply fit our adaptor collar over the fiber port, and insert the light amplifier into the port. Secure with the supplied screw and then attach your Fiberstars harness as normal.

You can now benefit from the great light output and features of a UFO illuminator without having the cost of replacing your fiber harness.

The adaptor can be supplied pre-attached to new illuminators or as a retro-fit kit for existing ones. Please get in touch to find out more.

The EFO Adaptor is designed to take a standard Fiberstars harness which has a 1” 7/8 ACME 10 TRAPEZOIDAL thread, and features an internal acrylic light amplifier which carries the light directly to the fiber ends.

A very powerful yet efficient fiber optic illuminator, powered by LED technology, which outputs white light only.

Extremely high power output makes this illuminator suitable for multiple lighting tasks where traditionally metal halide units have been employed. Almost silent in operation, the Sirius outputs light which is similar to that of a 150W metal halide lamp.

The Sirius has an inbuilt manual dimmer and dimming is also controllable via either DMX or 0-10V.

With a standard 30mm (1.2") fiber port connector, this illuminator is equally suited to new projects or for retro-fitting to existing fiber optic installations.
