Degree of Impact Protection
EN 50.102
The resistive performance of fittings to external mechanical
impacts the IK code prefix followed by two numbers.
Number Measure of protection
– impact energy (joules)
Test
00 No protection to this standard -
01 0.15 0.20 kg impact
02 0.20 0.20 kg impact
03 0.35 0.20 kg impact
04 0.50 0.20 kg impact
05 0.70 0.20 kg impact
06 1.00 0.50 kg impact from 200mm
07 2.00 0.50 kg impact from 400mm
08 5.00 1.70 kg impact from 295mm
09 10.00 5.00 kg impact from 200mm
10 20.00
When higher impact energy
protection is required
50 joules is recommended.
5.00 kg impact from 400mm
Degree of Temperature Protection
EN 60.598-2-13 (proposal currently under discussion)
The maximum permissible surface temperature and static load on the fitting
for a maximum protrusion above the ground by ground recessed fittings is
indicated by the ‘C’ prefix followed by one number. All luminaires should
meet both IP65 and IP67 protection ratings.

Photometric Data
Performance Cones
Cones are for single luminaires
Performance cones indicate beam spread, ie. a narrow, medium or broad
beam of light. The illuminance values given (lux/Klm) are the maximum values
within the beam for horizontal planes at various distances below the
luminaire. The beam diameter, ie. the approximate size of the light coverage,
is also given. The cone widths are calculated for an illuminance at the edge of
the cone of 50% of the maximum. By spacing luminaires at the beam
diameter for the appropriate height, the combined effect of adjacent cones is

to produce an acceptable uniformity along the centre lines between
luminaires (figure 1).

Polar Diagram of luminous intensity distribution
These provide a graphic representation of the distribution of light from a
luminaire. Often referred to as polar curves, they indicate the intensity,

The tables provided use luminaire Photometric data that has been measured
and tested in accordance with British Standard 5225 Parts 1 & 3 ‘Photometric
Data for Luminaires’.
Additional photometric data can be provided upon request.
All data is also available in CIBSE TM14, EULUMDAT and
IES NA formats.
A complementary lighting design service is also available, to provide
guidance and recommendations and to ensure lighting solutions are tailored
to customer requirements. Supporting this service are the latest computer
software facilities enabling accurate predictions and performance checks to
be carried FIG out. 9.
