UK GlobePhotometric & Optical Testing Services - Your Measure of Confidence in Independent Light Measurement

We are an independent lighting and optical test laboratory and your partner for testing LEDs, luminaires, lamps, displays, signs and vehicle lighting. From standard photometric data to photobiological safety testing, from training courses in light measurement to developmental testing of new products, let Photometric Testing save you time and money and help you to bring the next generation of ultra efficient lighting products to market more quickly. We provide training in light measurement, photobiological safety and lasers and offer measurement services for characterising the optical properties of materials - such as reflectance, transmittance, colour and BRDF / BTDF scatter.

For light souces, displays and signs, we measure the amount of light produced, its colour, its rendering quaility and its spatial or angular distribution. We also report the energy efficiency (LOR, luminous efficacy, energy efficiency index) and photobiological risk group. We compile photometric data in .ies and .ldt (EULUMDAT) standard formats as well as UGR glare rating tables. We also measure the optical properties of materials (reflectance, transmittance and scatter). » More    ► What is "flicker" and why is it a problem with SSL?
