Photometric Testing
Photometric testing is a critical service at CEC, supporting manufacturers, lighting engineers, and R&D teams in validating the performance, quality, and compliance of lighting products. Our testing infrastructure adheres to international standards such as IES LM 79, IS 15111, IS 16102, and IS 16107, and ensures precise evaluation of various light-related parameters under controlled laboratory conditions.
Our state-of-the-art equipment includes an Integrating Sphere, Spectrophotometer, Reference Lamps, AC Source, and Power Analyser, enabling full-spectrum assessment of optical, electrical, and temporal characteristics of lighting devices. The lab is designed to test both general-purpose and specialized lighting systems for residential, industrial, and commercial use.
From luminous flux to colour consistency, CEC delivers precise and standard-compliant photometric evaluations to ensure lighting products meet both regulatory and performance expectations.
