ZORTECH LED owns and operates a 1.5 metre Integrated Sphere (Photospectrocolorometer).


The sphere allows us to test any light source from as small as a single LED to as large as a 4 foot long fixture. The sphere performs 13 separate tests including Lumens (Lm), Colour (K), Colour Rendering Index (CRI), RGB %, Lumens/watt, Color Spectrum Graph, etc.

We test all lights that we sell. Based on the test results, we can provide our customers with lighting products tailored to their needs.


Light deterioration is a very common problem with HPS and Metal Halide lights especially. We can test your existing lights, find out how they perform, and if they need to be replaced.

If you have any questions about technical aspects of grow lights or any LEDs, science of light (Light Spectrum, PPFD, light efficiency, etc.) and/or LED applications for your needs, we will provide you with knowledgeable advice, and a solution that would benefit you.  

Testing of any third party products is available. Ask us for details.
