Luminaire
Testing Laboratory, Inc. (LTL) is an independent source of photometric
test reports for the lighting industry. In addition to producing
Roadway, Floodlight, and indoor Photometric Test Reports, LTL
also performs ballast characteristic testing, electrical system
testing, mining vehicle luminaire testing, and absolute photometric
testing. LTL uses two computer controlled, Type C, swinging mirror
goniophotometers to test luminaires. Test reports conform to Illuminating
Engineering Society of North America (IESNA) standards.
The
lab was established in 1989 in Allentown, PA because of its accessibility
to transportation and distribution. Through the years, LTL has
earned a reputation for producing highly accurate photometric
test reports in a time frame that fits today's high-speed marketplace.
All test reports since 2000 are archived electronically to allow
for instant email transfer of test reports. Through the use of
the most recent technology we can offer high speed delivery while
continuing to serve our customers with the same high quality service
we have provided in the past.
Tours
of LTL are welcomed and encouraged.
