Thank you for the opinion.
It would be great to hear of the first protected cell to be used in this light of any type as I am (still) trying to wrap my mind around 800 lumens ‘bursting’ from this XP L (?) vs the 500 I am enjoying presently from my ZL SC52 L2 (XM L?) with the same 14500 cell.
Is this merely a result of the higher (?) unprotected cell giving this LED more power…a more ‘powerful’/efficient LED…or both?
…showing my ignorance ‘big time’ here, I know… :person_facepalming:
I remember (now) once buying/trying an AW IMR unprotected cell in a ZL that I had and why.
What threw me was my ZL SC52 L2 putting out 300 lumens using an Eneloop and 500 lumens using a protected 14500 (which seemed almost impossible not long ago)….vs the UT01 putting out 500 lumens (AA) and 700 something using the unprotected cell.
Whatever I gained by using the protected cell seemed worth it for whatever the lumens turned out to be north of 500 (which seems twice as incredible as I thought the SC52 to be using an Eneloop driving 300 lumens).
Received it today, unfortunately the switch on mine is very bad. It only works if I press it in a special way with the nail of my finger. So far it is unusable. I hope I can get it fixed.
Please keep us updated and thanks for the heads up.
I would also like to hear from anybody on the difference in output between protected and unprotected cells if they (both?) fit in your light (thanks in advance)…
With a Xtar 14500 protected , i read about 100 lumens less than using the Efest .
(For all batteries : )
Also , highest mode seems to be able to perform better , it is programmed in the 1st or 2nd level from the factory ( from the 3 output leves of the highest mode , see “Light has programmable output levels for every mode” section in the OP ) .
I have been on holiday travel spending time at various relatives houses the past 1.5 weeks with the UT01 and its been great. I have my modes set up for the two lowest modes and then the two highest modes. Perfect for me… CANDLE > LO > HI > TURBO. So I don’t really have a MED mode. Love the cream white, green-free tint. Of all my NW cree tints this one has the least yellow too… which is good. My cousins friend has a black lab and we went out on a night hike along one of the local creek-side trails, and the UT01 did a great job. I mostly had it on hi and used turbo for short bursts, where it doubled up as a hand warmer too. (win-win !!!)
Travel rig. Solid performer with eneloops too, particularly around the house and I don’t need that much light.
EDC, compact and lightweight with a 14500 cell.
