Dear customer,
The following notice is to remind you that IESNA (Illuminating
Engineering Society of North America) has approved on 28 January
2007 a new classification system for the light distribution of
outdoor luminaires.
The new Technical Memorandum bares the name TM-15-07 “Luminaire
Classification System for Outdoor Luminaires”. According to this
new classification system, the words “Full Cutoff, Cutoff,
Semicutoff and Noncutoff” are not used anymore and are replaced
by percentages of lamp lumens in different zones. The words
‘’Type I, Type II, Type III, Type IV et Type V’’ and ‘’Short,
Medium, Long’’ are still used to qualify the transversal and
longitudinal distributions respectively. You can order the new
Technical Memorandum from IESNA if you want additional
informations regarding this new classification system.
IESNA understands that it takes some time to adopt a new system
and make all the necessary changes. Nevertheless, IESNA still
wishes that manufacturers and all concerned organizations adopt
the new classification system as soon as possible and publish
their photometric reports according to this new classification
system.
According to our quality management system, we must comply with
all IESNA official publication. Consequently, all photometric
reports published from this day on will be in accordance with
this new classification system.
The request form for photometric test available on our website
has been modified to let you choose this new classification
system. If you do not indicate your preference when you order a
photometric test, the new classification system will be the
default choice.
There will be additional costs for photometric reports issued
with the old classification system and for old reports issued
with the new system. Additional costs will also be invoiced for
customer who request photometric report with both classification
systems
Floodlights, traffic lights and indoor lighting luminaires are
not part of this new classification system.
