A lighting layout is only as good as the photometric file behind it. Catalogue values give a single lumen number; a real design needs the full intensity distribution.
We test the first batch of every order in an integrating sphere for flux colour and efficacy, and use a goniophotometer for the distribution file used in Dialux calculations.
This matters for compliance: road lighting classes specify uniformity and glare limits, not just average lux. A lens that looks bright on a catalogue page can fail the uniformity requirement.
Buyers can request the IES/LDT files with the quotation. It is a small document that prevents expensive surprises during commissioning.
