Photometric Labs
While Photopia is excellent for simulating photometry, there are often times when you must use a physical lab. These may include:
Confirmation of Photopia results
Significant thermal effects
Lamps or materials not available in Photopia Library
Physical testing required by code or specifying engineer
There are many labs available for photometric testing. We would recommend the following labs:
Independent Testing Lab - Boulder, Colorado
Luminaire Testing Laboratory - Allentown, Pennsylvania
Lighting Sciences - Scottsdale, Arizona
