Review: Ultrafire UF-H2 Infinitely Variable 1xAA Headlamp

But then when you compare it to the competition....

http://www.zebralight.com/H50b-Headlamp-AA-Flood_p_35.html

And that is on clearance and costs $45. I have one of the original Q5 ones of these, I think it cost $59 at the time and was worth it.

I have bought only two headlamps since the H50 about 4-5 years ago. A gimmicky flood-throw 14500 only light that didn't work and the 18650 version of this light. The H50 really is excellent.

The Ultrafire is more flexible and cheaper. But if the price can be brought down a bit more, I could probably be persuaded to buy another headlamp.

For a lot of people in the EU, a price of $28 or less removes import duty hassles and big Customs clearance fees.

Hmmm, how many estimated lumens by eye? Not sure, but it's about as bright as my Trustfire F20 on high, both with an Eneloop.

14500 support? I honestly don't know. It seems there are various versions of this light out there, in typical Ultrafire fashion. These two links at Kaidomain make me think that there are two versions- one is only AA with variable output. And the other is only 14500 with a single mode. But I don't believe any of KD's descriptions.

There's also this description on eBay. It claims to support AA and 14500 and be infinitely variable.

And finally there's this review on CPF, which claims that a 14500 works fine.

I think there's hope that we could probably persuade Manafont to get their price down a bit on this light, if we ask politely. ;-)

mmm similar to F20 on High, so about 130 chinese lumens. Probably 100 fenix lumens

Sounds about right. Thanks Fran!

The UF-H3 which could well have the same driver varies from about 3-120 lumens. I happen to have some 65mm long NiMH cells lying around if i can find them - they weren't where I first looked.

11

I also suspect that the UF-H3 does have the same driver, in which case it supports 3.7V, right?

12

That's what I'm thinking, which is why I'm looking for my 4/3A NiMH cells (Essentially 18650 in NiMH) which came from a laptop battery pack. Trying to make up a test adaptor for an AA Eneloop isn't working so time to play hunt the cell. I really must tidy up in this place.

13

Ah, 4/3A, I wondered if an 18650-sized NiMH battery existed. Thanks Don, please let us know if you get a chance.

14

fer18gts from ForoLinternas owns an UF-H3, he tried with one AA eneloop, and even with two in series, and it didn't light up..

15

Here you can have it for 29$: http://www.hkequipment.net/index.php?p=6&id=444&lang=en&msg=Session%20Expiried!&s=

Shipping 2$!!

Manafont should be convinced to sell it at that price.

16

Found the cells. Now where did I put the charger?

17

Yes, Fran is right, it must be a lithium only circuit. Which could mean there are two variants on the UF-H2.

18

Thanks for the great review. Very interesting light indeed and already added to my wishlist.

Just one question: If you lock out the tailcap to securely prevent the parasitic drain, how big is the risk that the tailcap comes off or closes the circuit accidently when carrying the light in a bag/pocket? Is this something that could be adjusted with a suitable o-ring?

19

Exactly none. There are two O rings - keep it between the two and no problem. At least on the H3

Pity it is $90 from Shiningbeam. I do doubt whether 360 lumens from a headlamp is actually useful but that's another story.

21

It depends on what you do with the headlight, I use a XM-L C2 as a headlight when skiing. Nice and bright, though I'd rather take my less bright Zebralight when viewing stuff at a closer distance : )

22

True.

For what I do with headlights, this is way past useful. |Others do different things.

I walk splay-footed. For me, skiing is an expensive way of hurting myself.

23

Thanks for the info.

Looking at the pictures at manafont there seems to be only one o-ring on the H2 tube but I think there is a second groove for an additional ring so it should work out fine. Well, I'll see when it arrives. Moved from "wish" to "ordered" ;)

24

Huny74, I think that there's very little risk of losing the tailcap if you carry it slightly unscrewed. It requires very little turning to break the connection, it still remains almost totally screwed on.

Let us know how you like it when you receive it!

25

Thanks for the info. I already like the light, mostly because of the UI. It will also be my first light shining sideways. Can't wait till it arrives (well, I'm afraid regarding this I don't have much choice...)
