Test Procedures
The Advantage of ITL
ITL takes great care in performing your tests, no short cuts are taken. We always allow adequate stabilization of the lamp and/or luminaire. ITL also selects an adequate number of vertical and lateral data acquisition points to accurately define your test sample. ITL has had over 60 years to perfect our test procedures.
Other Testing Labs
There are laboratories in the industry who have been known to take less than a full set of photometric data to represent a luminaire. Some have even been known to take just one quadrant of data to represent a quadrilaterally symmetric luminaire. Due to limitations in their test apparatus some labs cannot take a sufficient number of test data points to accurately define your test samples. Others have limitations where they cannot test your luminaire in the orientation that it’s applied in. We believe, there are also labs that do not allow the lamp and/or luminaire to fully stabilize before testing.
