GL OPTI SPHERE 500
Accessible luminous flux and radiant power measurement of LED lamps and modules
Compact integrating sphere system
GL OPTI SPHERE 500 was designed specifically for growing lighting companies in the booming LED retrofit business that need a quick and reliable solution to test & measure medium sized lamps and LED modules. It offers an excellent choice for any LED luminaire manufacturer interested in characterizing the quality of their product. This 50 cm integrating sphere generates immediate measurements of luminous flux, color temperature, luminous efficacy and many other important light characteristics.
With its small dimensions, the GL OPTI SPHERE 500 is a perfect table top instrument providing laboratory accuracy, without the need for a dedicated laboratory or highly skilled technician. This calibrated system is conforming to CIE global standards and all American and European requirements for professional LED light measurement instrumentation. Choose between any of our spectrometer options to create a high performance, easy to use sphere spectroradiomemter setup.
Install and measure
By default this sphere is equipped with the most popular lamp holders. The standard lamp post installed in the center of the sphere makes it easy to install different products and perform professional light measurements. An optional mechanical breadboard can be supplied to allow for easy installation of different LED lighting fixtures or small luminaire.
Accelerate product development
This instrument can be easily installed in a standard office space allowing R&D departments and engineers quickly and accurately measure lighting components onsite. Sending lamps and components for testing in the lab means long lead times and ultimately slows down the development cycle. Now, when new LEDs are delivered or a new board is fabricated they can see results immediately.
Not just for the laboratory
This flexible integrating sphere system can easily be adopted to specific customer’s needs and turned into a production tester or a quick production control unit which will help to measure lamps, luminaires and modules as they are manufactured. Larger distribution companies use this for quality compliance testing of purchased products before they are released to the market.

GL OPTI SPHERE 500 Usage
Your tabletop laboratory
The rapidly expanding LED retrofit lamp market demands quick & reliable solutions to test & measure small to medium-sized LED products. GL OPTI SPHERE 500 integrating sphere was produced to meet this need and delivers complete optical measurement of LED retrofit / replacement lamps with typical sockets like E27, E14 GU10 and others. As we rolled out the solution, it quickly became evident that this compact benchtop instrument is equally suited for use in a lighting laboratory as well as in R&D departments for immediate evaluation of components, prototypes and final products.
GL OPTI SPHERE 500 lowers the barrier of entry for professional light measurement. A dedicated metrologist or large dark lab are not required. Setup the system and start understanding your lamps in no time. The setup and operation ensure engineering staff generate accurate results even with only limited test experience. Our customers appreciate that you can just open the sphere, install the lamp inside and measure. This sphere is equipped with all accessories and components you need and our GL SPECTROSOFT software interface will help you to do it right.
LED modules, strips, lamps and more
Need to make a lot of different measurements and don’t have the budget or space for a large sphere? GL OPTI SPHERE 500 offers an excellent entry into the laboratory test & measurement space for LED modules, lamps and components that you use in lamp manufacturing. This integrating sphere can be combined with any of our spectrometers for accurate flux and color testing. Now you will be able to check components, diffusers, control the influence of new electronic drivers and produce reports immediately and frequently. Get photometric results for prototypes, verify the LEDs and components from your suppliers and get your light quality under control!
GL OPTI SPHERE 500 Features
Reliable measurement of light
All GL Optic spheres are delivered spectrally calibrated when purchased with the measurement instrument. Our spheres are universal and can be used with any GL Optic spectrometer. The inner walls of the sphere are coated with barium sulfate (BaSO4) which ensures high reflectance properties up to 97%.
CIE compliant
Measurement of LEDs compliant with CIE 127:2007 and new CIE S 025/E:2015. This sphere also complies with other global standards and all American IES LM and European EN requirements for professional LED light measurement instrumentation.
Configurable
Use the standard GL OPTI SPHERE 500 system with universal lamp post for optional mechanical breadboard for 4π measurements of small lamps and modules. All spheres also include a side port for accurate measurement of 2π sources.
Additional adapters, mounts for temperature control or specialized holders are also available on demand. Please contact us to share your requirements.
Automated self-absorbance correction
The integrated LED auxiliary light source is fully controlled by the GL SPECTROSOFT software to enable quick corrections and deliver optimal results.
