Optical Measurement

We use our in-house integrating sphere to measure light output across the entire beam pattern and to validate LED output and coloration as part of our design and manufacturing process. The 1 meter sphere is available to test lights from customers and other manufacturers.

We ship every LED SeaLite, SeaLite Sphere, SeaLite Lumos Remote, and Nano SeaLite with its own True Lumens Report and the confidence that you will get the specified output and coloration.

  • Integrated spectrometer
  • Multiple luminary positions
  • Lumens, CRI and spectral output.
An integrating sphere, also known as an Ulbricht or integrated spectrometer sphere, is used to concisely capture the flux (total power) of a light source as well as precisely measure the color of the light. Utilizing the concept of Lambertian reflectance to scatter the light in a diffuse manner, the total light energy created is measured without inaccuracies caused by directional characteristics of the lights’ source. Read more about integrating spheres in general.The inside of the sphere has a non-fluorescent reflective white coating which effectively scatters and distributes the light equally to all other points. We use this to measure the total light from the lamp over all angles of illumination and observation.

With a readout in Lumens given and a mapping of color temperature against a black body graph, a complete characteristic of the light is quantified. A True Lumens Report will be generated and provided for each light that is tested. The sphere’s light-port accepts apertures up to a maximum diameter of 3.5 in. with adapters available for smaller dimensions.
