Photometric & Goniophotometric Test Equipment & Services

Photometry Banner

Light measurements don't have to be testing with photometric equipment from Pro-Lite and independent measurement services from Photometric Testing. If you’re developing the next generation of ultra-efficient lighting, you will know how important fast, accurate and affordable test equipment is when it comes to being able to bring new products to market quickly. Pro-Lite can help save you time and money with our integrating spheres, goniophotometers, light meters, measurement services and equipment hire.  



Labsphere Integrating Spheres


Illuminance Lux Meters & Colorimeters

Goniophotometers   Big Sphere   Photometers

Goniophotometers perform angular analysis of light sources and displays. Our far-field goniophotometers are used to test vehicle lighting, traffic signals and general lighting prodicts, while our near-field goniophotometers are used for testing flat panel displays and luminaires. Our source imaging goniophotometer generates Radiant Source Model files. The Imaging Sphere is an ultrafast goniophotometer for LED and display view angle testing.

Labsphere integrating sphere
spectroradiometers provide the fastest means of measuring the total light output of lamps, LEDs, luminaires and solid state lighting. Sphere sizes range from 25cm to 3m, which means that we have a solution for testing any size of light fitting. Entry-level LFC spheres are the most affordable systems (like-for-like) on the market.

  Konica Minolta photometers and colorimeters aren't like most affordable lux meters because they give accurate readings regardless of the type of light source under test - even with white LEDs. We also have Photopic/Scotopic meters which enables the S:P ratio of lights to be calculated.

Flicker Photometer

CL-500A   Konica Minolta CL-70F   Cronus

The Konica Minolta CL-500A is a new type of lux meter based on a spectroradiometer rather than filtered detectors. As a result, the CL-500A gives accurate illuminance and colour readings with any kind of light source - even coloured LEDs. Measure illuminance (lux), correlated colour temperature (CCT, Kelvin), CIE chromaticity (xy) and CRI colour rendering indices (Ra, R1-14).

Konica Minolta's latest spectral lux meter - the CL-70F - is our most affordable, hand-portable illuminance spectroradiometer. It is a slim-line touuchscreen design and being based on a spectrometer helps to ensure that the CL-70F gives accurate readings with any type of light source, including LEDs. You can measure the spectrum (380-780nm), illuminance (lux), correlated colour temperature (CCT, Kelvin), CIE chromaticity (xy) and CRI colour rendering indices (Ra, R1-14).

  The Cronus by Admesy is an ultra high speed spectral photometer that can measure the both the illuminance and the photometric flicker of light sources - both IES flicker percent and flicker index are reported. In addition, the Cronus records illuminance (in lux) as well as chromaticity, CCT and colour rendering (CRI).

Photometric Equipment Hire


Photometric Testing Services

Hire   40" Integrating Sphere    

Pro-Lite rents photometers, colorimeters and spectroradiometers that are used to measure the "brightness" and colour of displays and all manner of light sources (lamps, luminaires, LEDs etc).

Pro-Lite's sister company Photometric & Optical Testing Services provides independent measurement services for lighting products. Services are provided for the measurement of total luminous flux (lumens), provision of standard photometric data in IES & EULUMDAT formats and for assessing the photobiological safety of lighting products in accordance with EN 62471.
