What very many people don't know: The DIFFERENCE between a WARM light (Cree, day type), and the strong white COLD (very ARTIFICIAL) light.
This is what very many people don't know: The DIFFERENCE between a WARM light (similar to the day light, at 5000K even similar to the sunny day light), and the typical light of the old neon tube, w. strong white COLD lighting, feeling/looking VERY ARTIFICIAL.
As bzh_crooks very well put it, the Cree bulbs lighting is much, much warmer (and less 'white').
It's all a matter of taste and CREE is one of many makers of LED chips, though CREE is the highest cost producer and has demonstrated the highest lumens/watt LED efficiency in the research laboratory. Of course, one must really evaluate CREE based on what they sell, not what they can show in the research laboratory.
By test in this case, you meaan that one would not care if its light is day-like (natural-like), or like the neon light in a store, public restroom, or any other cheap/poor lighted place? Try to be honest.
