Nautilus 2 – Circular LED Luminaires

The Nautilus 2 range offers decorative surface-mounted circular luminaires. They incorporate high output white LEDs within a ‘sealed’ polycarbonate light source enclosure. This minimises loss of efficacy due to dirt ingress.

The Nautilus 2 range offers an exceptional opportunity to design contemporary lighting installations. Nautilus 2 are aesthetic luminaires specifically designed to offer mains only or maintained emergency lighting. They have optional integral Micro-Wave presence detectors for switching the mains operation where required. Nautilus 2 luminaires comply with EN60598.

The luminaires are available with mains only or 3 hour duration Maintained emergency operation. Mains and emergency versions may be specified with an integral Micro-Wave presence detector to switch the mains lighting. Sensitivity, ‘on’ time and ambient light levels can be selected during installation.

 

The emergency lighting versions utilise integral high temperature Nickel Cadmium batteries. Maintained versions 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.
