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.

Nautilus 2 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 Microwave presence detectors for switching the mains operation where required.

The mains driver and emergency lighting gear is installed in the back of the housing away from internal heat sources. The main luminaire housing is installed by twisting on to the first fix ring.

Nautilus 2 luminaires comply with EN60598.

DALI and Self-Test logos

Standard Nautilus 2 luminaires provide 2040 Luminaire Lumens at 23 watts (89lm/W).

The luminaires are available with standard mains drivers or DALI mains drivers and with integral 3 hour duration Maintained emergency gear, again with the choice of standard or DALI/Self-Test operation. Mains and emergency versions may be specified with an integral Microwave 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.
