Mine is also ~4000K, which I generally don’t like that much, but somehow it fits this light. I saw nice reds and generally vivid colors with it - I like how it turns out so much, that it will be a keeper.
As soon as my UT01 arrives I will measure it. Of course I ordered NW. I feel something that will be similar to the UT02 that I got a few days ago. From the measurements, 4350K came out instead of 5000K. The measurements are done with the eyeone Pro calibrator, so it is a fairly accurate measurement. I also get a spectrum of timbre.
I feel the same, it has nice color rendering. Sometimes I like a warmer tint using around the house inside late night when I’m sleepy, also in a movie theater etc., anytime colder white could be somewhat “offensive” to the eyes.
Also I only ran mine on an Alkaline primary, I’m wondering if I’ll see slightly different or cooler tint with higher output when running it on 14500.
Thanks for doing this. I’m really liking this little light, would be interesting and useful to know the actual CCT.
Please also let us know if it has only 3 programmable modes instead of 4, as I described in previous posts, (HI mode factory set - not programmable) and what your date of ordering was.
beam0. Your light is almost certainly programmable in all four modes. The problem you are likely having is that an AA alkaline can’t deliver enough power for the turbo mode, so they all look the same. I’ve seen the same thing with an Eneloop once it discharges a bit.
As brought to my attention by several people in the review thread the problem was the battery, the HI mode will not program with an alkaline cell, even a new one with 1.6v, it will go to HI but remains steady and doesn’t ramp.
With the 14500 I’m now able to program all 4 modes.
Today I received my UT01. Color NW.
First conclusions:
The color is much warmer. 3789K came out of my measurements. I would prefer closer to the declared value.
I am waiting for a battery of 14500, so the first tests with eneloop AA.
The amount of light from 1m is 2209 lux. Pretty good.
The switch is very unstable. Works, does not work, works again in a moment. Evidently the fault of the switch because I measured the circuits.
How bad is the parasitic drain on this light? I have it on order as a gift to my parents as a backup light and they will leave battery in the light for sure.
