Self contained emergency lighting
Our products are designed to comply with the requirements of UK law and the relevant industry, national and international standards, and should not be modified in any way.
All self-contained emergency lighting luminaries require a continuous 220-240V single phase 50Hz supply to keep the inbuilt batteries charged. The supply must be taken from the lighting supply in the area being protected, in order to activate the emergency lighting if the mains supply in that area fails. In addition, maintained fittings require a separate switched live supply enabling the fitting to be operated normally from the mains supply.
The design life of a T5 fluorescent lamp is 5000 hours, so if maintained fittings are light for 24 hours a day, lamp life will be approximately 6 months. If lamps are not replaced promptly, the luminaries circuitry may be damaged.
Self-contained emergency light luminaries are only suitable for environments with ambient temperatures between 0-25℃.
Light output factors are as follows. Note these values are given to permit checking of correct operation. The full photometric distribution data for individual fittings should be used to determine correct lighting levels on escape foutes.
Ballast lumen factor (BLF)
4 WATT – 0.22, 6 WATT – 0.20, 8 WATT – 0.15
NOTE: Ballast lumen factor is the proportion of light output from the luminary on battery compared with the light output when on mains.
