2. WHAT IS LUMINAIRE?
A light fixture (US English), light
fitting (UK English), lamp,
or luminaire (The Illuminating
Engineers Society, IES) is “a complete
lighting unit consisting of a lamp or
lamps together with the parts designed to
distribute the light, to position and
protect the lamps, and to connect the
lamps to the power supply.”

3. HOW IT BEGAN?
• Fixture manufacturing began soon after production of the incandescent light bulb.
When practical uses of fluorescent lighting were realized after 1924.
• The three leading companies to produce various fixtures were Lightolier, Artcraft
Fluorescent Lighting Corporation, and Globe Lighting in the United States.

4. TYPES:
 Luminaires are classified by how the fixture is installed, the light
function or lamp type.
1. Free-standing or portable
2. Fixed
3. Special-purpose lights

5. FREE STANDING/PORTABLE LUMINAIRE:
• Can be placed wherever required – anywhere in the room, in any
position relative to the workstation, where it focuses its light on a
specific visual task, economically and efficiently.

6. FIXED LUMINAIRE:
• Permanently installed in a specific location and cannot be easily moved or adjusted.
Unlike portable or adjustable lights, fixed luminaires are designed to provide
illumination to a particular area or space without the need for frequent repositioning.
These fixtures are often installed on ceilings, walls, or other fixed surfaces.

7. SPECIAL-PURPOSE LUMINAIRES:
• Designed for specific applications or tasks, beyond general illumination.
These fixtures are tailored to meet specific requirements in terms of
light distribution, intensity, colour temperature, and other factors.

8. SELECTING A LUMINAIRE:
• During the process of selecting a luminaire, users will clearly notice that
there are two distinct application categories: outdoor or indoor. Once
this has been determined, they can then consider the wattage, lumen
output and colour temperature.
• Selecting outdoor and indoor luminaires in the past was easier when
fewer options were available. Nowadays we use the IP Rating (ingress
protection rating) to select the most suitable luminaire for the conditions
that it will be installed.

9. When selecting
luminaires for purely
interior environments,
ideally where there is no
chance of exposure to
water or humidity, a
rating of IP20 will be
sufficient to reduce dust.
In semi-outdoor areas
such as porches and
eaves, high traffic areas
like corridors, or wet
areas like bathrooms, a
minimum rating of IP44
is recommended.
Gardens or outdoor areas
that will be exposed to
weather and the elements
should have a minimum
rating of IP54.
In the case of luminaires
that will be submerged
underwater, for example
in a pond, lake or
fountain, a minimum
rating of IP68 is required
in order to prevent water
from entering the
fitting.
