Thanks for chiming in and too bad you don't like it. If you want more throw, the h600w xhp35 is probably a better option. Is there alot if variation in tint across the beam of the h600c?
Actually I did not say that I did no like it, I said I was surprised. Basically that surprise was the result of my failure to do the homework before ordering this particular model. I read that High CRI is great for true color reproduction, I knew that the light would be yellowish since this is 4000K CCT FL, I also read that due to High CRI the efficiency will be 10%-15% less in comparison with cool white but in reality I simply did not know what would it give (all factors combined) in real world test. May be if I could find some beamshots and read some reviews when I would be more prepared for the first usage of this particular FL.
All I all, since I am going to keep it I will definitely find a use for the FL and most likely it will be something like working on my car in the garage or on different electronics projects when extra light is always beneficial.
To answer your question: I did not notice any variations in tint across the beam, it is steady yellowish (obviously, brighter in the center but still the same color). So, no rainbow on the (reasonably) )white wall of my garage or other artifacts.
And finally: I dont know if I am allowed to post here links to different FL related sites but I will try. There is a web site that allows you to see beamshots for ZEBRALIGHT H600FC MK4, which is also High CRI, 4000K - I found it after I already ordered my FL. Check it out and you will see what I mean by saying that the light is yellowish:

Switch interface to English, click on "Search flashlights in the database", select "ZEBRALIGHT H600FC MK4" -> "Cave". Now you can choose different levels (High, Mid, Low) and check the picture. My h600c is very close (if not identical) to the shown beam pattern and the color.
Have a good weekend.
