So far so good, so screwed and turned the thing into a white paper balloon light. The brightness was very good, the lighting also, but as this part shall have a CRI of 85, I do not know. In addition, my lamp was also very blue before, ie whether it can agree that the white balance is actually only just over 6000K, I do not know. Came to me actually rather even higher before (it had however not measured it).
So, but now my impression of Light quality: Skin tones look like risen directly from throwing up, totally flat and pale, also the color contrast is generally so bad that I almost dizzy under this light. In addition, the white suits absolute zero to my monitor (as said calibrated at 6500K) because this lamp is a good bit bluer than the monitor - a blank page on the screen appears a so suddenly beige-yellow. It is frankly much easier to work on the monitor with halogen lighting in the room, although the 3200K halogen lamp actually much more different from the White Point.
The Tiwin lamp did not work for me so, because the color reproduction and the light quality is so bad that I do not even want to have in the workshop that thing. I will as I said almost dizzy under this light, because the contrasts act so strangely unnatural.
I have to say that I myself as a cameraman with light a little familiar, I know what color temperature and CRI is, and have also seen some LED lights (for home and as headlights), so I know you're with LED definitely can put a better light.
Whether this light matches or with the type of the chip test, the big question, because a CRI of 85 is should not look so cruel in principle. But perhaps worse acts indeed a relatively poor CRI at a higher color temperature? Maybe I do not know. With prof. Headlights they say in any case that the CRI should best be above 95, and looks quite different! Such LEDs because there are also, but not for 14,95 ...
