Important notice:
I updated the luminance values for all LEDs shown in test chart including XHP35 HI C4 / E2. I used another E2 sample for luminance testing due to destroying the sample used for first light flux / luminance test.
To ensure more realistic values for 'real-life' conditions (flashlight use / secondary optics) I established a new testing method to determine the luminance with a SMO reflector. All upcoming and already existing tests will use this method!
Updating of my other tests will be done in the next hours / days.
