We accept lighting fixture distribution measurement tests!

We would like to introduce the "Light Distribution Measurement Service" provided by our business partner, Three S Co., Ltd. We offer the "Light Distribution Measurement Service," which measures the spread of light and the appearance of color of lighting fixtures at a reasonable price. As an OEM manufacturer, we hope to assist companies that wish to conduct light distribution simulations for their products under development. Our light distribution measurement system uses a "three-axis goniophotometer" capable of measuring from 40W bulbs to 1200mm-sized linear lighting fixtures. We employ a high-sensitivity, electronically cooled, back-illuminated spectrometer as the detector, allowing us to measure not only light distribution but also spectral irradiance spectra, total luminous flux, and colorimetric measurements. We provide the necessary inspections and data at an affordable price. For inquiries, please contact Ipros, Shimada Co., Ltd., or Three S Co., Ltd. https://three-sco.jp/measurement/
