Emergency Lighting
Applications - Case Study
This hypothetical application gives
examples of areas that require
emergency lighting.
Office
Type: Open area
General requirements: computers widely used on modular desking
systems require the elimination of screen glare. Direct/indirect luminaires
(like Jupiter II or Menlo
3
) brighten the ceiling
Emergency requirements: open area. Exit signs must be visible from all
points. Design integration by use of emergency versions of mains fittings or use
Voyager LED.
Corridor
Type: Escape route
General requirements: a link between different rooms where good
levels of lighting are important, but without sacrificing ambience. Some
spotlighting for specific features.
Emergency requirements: clearly defined escape routes. Directional exit
signs must be used to clearly indicate escape route. Design integrity
maintained by using emergency versions of mains fittings (e.g. Amazon
Bulkhead or Cruz downlight) for infill lighting.
Voyager LED with specific corridor optics offers maximum spacing.
Toilet/washroom area
Type: Open area
General requirements: functional areas that must reflect the design
approach of the building as a whole and provide adequate lighting.
Emergency requirements: open area. In toilet/washroom cubicles over
8m
2
two emergency* luminaires are required. These can be emergency
versions of mains fittings or separate dedicated emergency products (e.g.
Voyager LED or Voyager Exel emergency luminaire).
Toilet/washroom cubicles less than 8m
2
require emergency lighting
if there is no ‘borrowed’ light (e.g. light coming in from a high level
window).
Plant room
Type: High risk task
General requirements: good light levels, impact resistance and durability
are key criteria.
Emergency requirements: high risk task. Area specific tasks must be
completed in the event of mains failure. Special quick response fittings such
as Voyager Twin Spot should be used**or Voyager LED (task or spot)**.
Show room
Type: Open area
General requirements: use of spotlights highlights exhibition panels and
exhibits. Downlights give more general lighting whilst providing dramatic
ambience
Emergency requirements: open area. Exit signs must always be visible.
Emergency versions of downlights (e.g. Cruz) used to integrate with
design and Voyager LED Spot.
Conference
suite
Type: Open area
General requirements: good dimmable lighting is required, with a mixture
of linear fluorescents and downlights. Local spotlighting for lecture area.
Emergency requirements: open area. Exit signs must always be visible.
Emergency versions of linear fluorescent luminaires (e.g. Jupiter II) integrate
with mains lighting scheme. Emergency versions of downlights (e.g. Cruz)
used over clearly defined escape routes. Auditoria additionally require 0.1
lux along a line 1m above the floor.
Escape stairs and routes must be lit to the normal requirements.
Reception
Type: Open area
General requirements: an area requiring high visual impact, where use of
decorative wall and ceiling mounted products create stylish ambience,
whilst downlights and spotlights add focus.
Emergency requirements: open area. In public spaces, exit signs must be
lit whenever there are people in the building. Stairs require a minimum
of 1 lux on the tread of each stair. Emergency versions of wall and
ceiling mounted decorative products (e.g. Glacier II pendant or Cruz
downlights) integrate with design and provide aesthetic impact.
Stylish exit signs match the design-led focus for this area (e.g. Voyager
LED).
Kitchens
Type: Open area + High risk task
15lux in 0.5sec on the cooker surface
Treatment Room
Type: Open area + High risk task
15lux in 0.5sec on treatment area, normally the bed or couch.

*EN50172 requires a minimum of 2 emergency luminaires to be used in open areas and compartments of
an escape route (e.g. part of a corridor between fire doors).
**Plant rooms without moving machinery or with low potential risks can be lit as standard open areas.
Generator rooms require self-contained emergency luminaires.
