MezzoLite – LED Exit Sign

The MezzoLite LED Emergency Lighting Exit Sign provides an excellent viewing distance of 30 metres. Although still a ‘box’ design it offers much better aesthetics when compared to conventional emergency lighting exit sign boxes.

MezzoLite Exit Sign luminaires feature attractive Polycarbonate enclosures with a sloping front opal panel and screen printed safety sign legends.

The integral rechargeable batteries and charger/driver PCB are mounted on the back surface and the advanced wide angle white LEDs provide even and effective illuminance across the legend.

MezzoLite is available with DALI and Self-Test.

The MezzoLite range is supplied with Maintained operation as standard providing 3 hour duration. (Non-maintained operation is available by excluding a switched live supply). Pictogram legend panels complying with the EC Safety Signs Regulations and latest ISO sign requirements are available.

The benefits of the modern white low power LEDs include long life (typically 50,000 hours+), excellent energy efficiency (>100lm/W), low operating temperatures therefore improving the life of the internal Nickel Cadmium (NiCd) batteries and good operation at low ambient temperatures.

The MezzoLite exit sign luminaire fully complies to the requirements of EN60598.2.22. It offers bright and even luminance across the legend panel ensuring maximum visibility in the event of an emergency.

DALI / Self-Test Options:
The MezzoLite LED luminaires can be specified with integral DALI/Self-Test gear providing automatic Self-Test in accordance with BSEN62034 or fully interoperable DALI operation when connected to a DALI control system.
