The Ax LED bulkhead utilises an IP65 rated polycarbonate base and fresnel lens housing 16 high output white LEDs and constant current maintained drive circuit. The luminaire provides 90 lumens and the lens generates a wide intensity distribution ideal for providing good illuminance on the escape route. The polycarbonate lens can be fitted with 100mm high, self-adhesive safety signs. A deep (150mm) opal diffuser is also available to provide double sided signage if required.
The Ax LED bulkhead luminaires are available for normal mains lighting or with integral Maintained emergency lighting control gear (non-maintained operation achieved by excluding a switched live supply).
The 16 white LEDs provide 90 Lumens and M3 versions also offer 3-hour emergency lighting duration from integral Nickel Cadmium batteries. As with all LDL maintained luminaires the AX/M3 maintained units can be used for standard switched mains lighting but will automatically provide emergency lighting in the event of a complete loss of normal mains supply.
The benefits of modern white LEDs are well documented. These devices are very energy efficient and offer very long life (typically 50,000hours +). In addition, LEDs will operate at low temperatures (no cold starting problems) and do not create high temperatures, therefore, improving the life of the internal batteries and making the bulkhead suitable for use in cold stores etc. Ax bulkheads are ideally suited for a wide range of emergency lighting applications offering 4-5 years of maintenance free operation.
The luminaires fully comply with the requirements of EN60598.2.22 and their low energy consumption assists with compliance with Part L requirements.
