Dark-Room Photometric & Quality Laboratory
Every lumen and polar distribution curve published by PVS Sparks is empirically verified in-house through calibrated goniophotometry, integrating sphere spectroradiometry, and 48-hour thermal burn-in stress aging.
Laboratory Testing Capabilities
Verified testing equipment and measurement protocols utilized at our manufacturing facility.
Type-C Goniophotometer & Dark Room
Spatial Luminous Intensity DistributionOur calibrated Type-C goniophotometer rotates fixtures across vertical and horizontal optical planes in an absolute dark room to measure spatial light distributions and generate exact industry-standard photometric files.
2.0m Integrating Sphere Spectroradiometer
Total Flux & Color Spectral AnalysisMeasures total radiant power, luminous flux, and precise spectral power distributions across 380nm to 780nm wavelengths to ensure strict color consistency.
Electrical & Thermal Validation
Strict multi-tier testing pipeline eliminating field infant mortality.
48-Hr Thermal Burn-In
Continuous elevated ambient temperature cycling at 45°C detecting any early component anomalies.
Surge Immunity up to 10kV
High-energy surge generator simulating grid fluctuations, lightning strikes, and industrial switching transients.
Hi-Pot Insulation Test
High-potential AC breakdown test (up to 3.75kV) confirming dielectric safety between active circuits and aluminum chassis.
IP65 / IP66 Pressure Test
Oscillating water spray and high-pressure hose testing verifying silicone gasket seals for outdoor fixtures.
Request Photometric IES Data & Test Reports
Lighting designers and MEP consultants can request native .IES files, spectrometer chromaticity data, and compliance test certificates.
