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.
Ordered one of these 9 days ago at GB and our postal services mailed me that I will get it today. But the 14500 batteries are not here yet so can’t test it fully
Actually ordered 2, the second one was ordered couple days later.
