LED emergency lighting luminaire with diffuser optic. Can be surface-mounted or semi-recessed with accessory box. Luminous power and duration during an emergency vary according to the position of a jumper during the installation phase. Emergency conditions:
- 700 lm for 1h
- 500 lm for 1.5h
- 400 lm for 2h
- 300 lm for 3h
- Maintained (SA): 435 lm
12 h recharging time for maximum capacity.

The Motus luminaire offers 3 operating possibilities:
- Self-diagnosis (stand alone): automatic tests and feedback via a twin-colour LED with the option of a manual test for local checks that are activated by pressing a specific point on the luminaire. Built-in red/green LEDs for indicating various device states: OK/Test in progress/Battery disconnected/Device faulty.
