• Using a 2 meter Integrated Sphere, light testing can be performed on fixtures up to 4ft x 4ft
  • Available tests include: lumen output, CCT/CRI calibration, electrical, thermal, insulation contact
  • Characterization reports produced for light engines, optics, drivers, encasements and overall fixture designs
  • Our electrical engineers and technicians can design and prototype new light engines within 1–3 weeks


Arkalumen is proud to provide light fixture manufacturers support throughout the product development process. Arkalumen Lab was launched to take LED fixture design to the next level and offer full prototype, testing and analysis services to our customers. We believe that specifications from LED vendors need to be validated, custom light engines should be built in an iterative approach and quality products are built through time effort invested into engineering and testing.





With the ASP-IS-2000 Integrating Sphere, Arkalumen's photometric laboratory helps clients realize their light measurement testing needs for not only light engine boards, but also full fixtures up to 4 feet in size. Arkalumen engineers and technicians are dedicated to producing timely, accurate reports and documentation on the spectral qualities, temperature characteristics, and luminous efficacies of a variety of lighting sources. We welcome our customers to ask about our lumen-evaluation service as a low cost means of preparing for certification testing for LM79, DLC, and other industry standard tests.


Thermal management is key to the development of LED light fixtures that will meet specifications and last the test of time. Arkalumen offers customers thermal testing and analysis services that can highlight areas of concern in design so they can be improved during the product development process, rather then during safety certification testing or, much worse, after installation in the field. Thermal testing early in the design cycle can allow for the right choices to be made on everything from LED to heat sinks to the material used in the printed circuit board (PCB). 


Case Study

The chart above illustrates one case study of a 2200 lumen, two foot light engine that was tested with an FR4 PCB and with a PCB using high grade aluminium. The difference in temperature at the solder connection to the LED in these two otherwise identical light engines was greater than 18° C.
