Joule Range

Combined Mains and Emergency Lighting Ballasts

Designed in 1990, the range of Joule ballasts have become a benchmark within the Lighting Industry. They offer the user the ability to satisfy the need for a ballast and a conversion module with one combined ballast saving space and money in the process.

Joule ballasts are capable of providing full lumen output from the lamp when mains is healthy and optimised levels of emergency lumens when the mains fails. This range has now been extended to include other compact and T5 circular lamps.

Perferm™ Technology is now incorporated into some of the Joule range, which allow for use with low mercury content lamps either when the luminaire is first supplied, or during subsequent re-lamping.

The range of Joule ballasts have been tested and approved by BSI in accordance with EN60924, EN60925 and EN60928 and are British Standard Kitemarked.

All of the above products are for 3 hour duration, for other durations, specify the required time period e.g. P3 for 1 hour duration becomes P1.
