Firefly Electronics is a specialist electronics company based in Cardiff, Wales, UK which manufactures and sells the Firefly2 ultra-sensitive photographic Slave Unit. This compact unit is used for triggering flashguns or flashbulbs remotely and works by detecting the brief pulse of infra-red radiation which is produced when a flashgun goes off. It is far more sensitive than most other slave units on the market. The Firefly 2 is suitable for all types of photography - in the studio, outdoors or in caves.

The Firefly 3 is our latest design for use with digital cameras, which incorporates David Gibson's circuit.
