Update 11/29/2025
The list has been comprehensively updated to show all LED tests performed to date. Tests, diagrams, and spectra are linked in the table as usual!
Hello!
Here are all my LED tests listed. I already started with them several years ago but had to make a break for some time. Since the end of 2022 I testing both modern and older emitters for performance and color properties.
If tests are only available in German, these are marked along with the link. These are listed for the sake of complete documentation. You can read them with DeepL or Google translate, if necessary. If English test is available, it is linked directly in this table.
The newer tests are all done with following measurements:
- light flux and electrical characteristics to absolute maximum, in integrating sphere
- luminance measurement
- color measurement (spectra, CRI and other numbers)
If you would like that I test a specific emitter or provide test samples, please contact me via PN.
Tip: for searching press Strg+F to look for specific emitter name.
