The Photometric Toolbox software (PTB) creates, edits, repairs, reports, compares and converts luminaire photometric data in IES, CIBSE or EULUMDAT formats. Specifiers use PTB to compare performance characteristics of similar luminaires, create iso-illuminance templates and visualize light distributions; manufacturers use PTB to edit and repair files, change type B to type C formats and convert IES to European standards or visa versa. The first and most robust analysis tool for luminaire photometry, a requirement for every lighting professional.
