Not getting any brighter than ~medium sounds like the LVP doing its thing…. at least thats what mine does.
Mine at that point will turn on and off however.
I am guessing there is a tolerance or window for the circuit, so the actual voltage level may vary from light to light. 1.1V - 1.0V might be within range for the LVP.
It sounds to me like you just have an over-protective LV circuit.
I have some 5A tints in other 1xAA lights (emitters that I got from Intl-Outdoors), and these ‘alleged’ 3D UT01’s are remarkably close - which is fine by me. :+1:
I have Astrolux S1 3D (neutral white), the tint of which I like.
Comparing the UT01 neutral white (supposedly “3D” tint), this is a much warmer — in fact I compared it with a Convoy S2+ (XM-L2 T6-4C tint), and the two tints are closer to each other, or the UT01 “3D” could even be very slightly warmer…
Thanks, I only use eneloops so I don’t want to know 14500. I’ve been reading a lot about UT01 in this forum and it seems there are problems when using NiMh so I guess I won’t be buying this and go for Sorfirn SP10B instead.
That would probably be wise.
I am not sure what the current draw is. FWIW I leave my UT01 on candle mode overnight all the time… many nights in succession. I use it as a nightlight with a 2000mah eneloop.
