Another thing that the light does. You can set it on it's back with the beam pointing to the ceiling. It just rests on the clip and the screws that hold the clip on and it works for ceiling bounce if you want.
It's kinda weird how much throw the little light has. With all the flood you wouldn't think it would have any throw but it does surprisingly well.
The light seems well made and has a good finish but I have to say, This thing is ugly. It looks like it fell out of the ugly tree and hit every branch on the way down. It's so ugly it almost makes it's way back to cute.
The heatsinking in the head is excellent, on AA's I don't see heat being a big issue. I don't think it is an issue on any single AA light unless you are using 14500's. I don't remember ever having anything fry on an AA light with Alkies or Eneloops.
Has anyone checked this light to see how waterproof it is?
You're welcome Huny74. Yes you can lock out the tailcap. I would recommend doing so if you are going to carry the light in a backpack or something like that as the button does click on quite easily.
I'm sorry to say that 8 days later, my UF-V4 is dead. Well, maybe not completely dead but it looks like it only has about 20 lumens left. It has been slowly getting dimmer each time I use it. At first I thought it was just my eyes playing tricks on me. After reading about some saying the light will work with 14500 and some saying it won't, I decided to put one in it and check it out last night. I figured that the light was getting dim enough that if I killed it, it wouldn't be a big deal considering what I paid for it in the first place. It was much brighter with the 14500. I only tried it for a few minutes and turned it off. This morning I put a AA NiMh back in and hardly any brightness at all. I changed back to the 14500 and it turned on for a second and then went off. Back to AA NiMh and still very dim.
I'm going to order one from CNQ that says it will use 14500 batteries.
Hmm, so are you saying it was already dying ("It has been slowly getting dimmer each time I use it") on the AA and then you tried the 14500? Or was it fine on AA until you tried the 14500? Clarify please.
Yes that is what I am saying. It may be my fault. Everything changed when I decided to take the light apart and have look under the reflector. I have never modded a light and this was my first attempt at taking things apart. I could be wrong but it seems that when I put the light back together the beam changed. It seemed much more of a yellow color. I thought I was just seeing things and didn't really remember what it had looked like before. I played with the light for a few days and it just got gradually dimmer. It was kind of like boiling a frog in a pot. The frog doesn't know that you keep turning the heat up because you do so a little at a time. Soon it's much hotter than when you began. Same way with my light. When I finally noticed that it was getting dimmer was when I shined the UF-V4 against the wall next to my Zebralight H51. When I first got the UF-V4 I noticed the H51 on the High Low mode was about the same brightness. Now there is no comparison.
Sorry to hear about that! (ordered one two days ago after reading this thread)
Has the tint shifted to brownish? Maybe it's an overheat issue because of the apparantly poor stock heatsinking from the LED to the body (referring to Chicago X's post #8)? If the current to the LED still is OK it maybe worth trying to swap the emitter and improve the thermal path.
