iTP Light H01 Headlamp

ooooh!!!

Early adopter territory. It is brand new. It has been noted on Candlepower Forums, but I am not sure anyone even has one yet and I do not think there is even an informal review yet.

Definitely bears watching, though.

Looks great and sleek as a flashlight. But the picture of the attachable belt seems… well not UL.

And is that metal? It could be plastic.

50 g though, less than 2 oz?

With a AAA battery that would make it…?

Would love to see how it tests against my petzl zipka

edit:

thanks for the heads up on the headlight, john. pun intended

You can see it listed for sale at $29.95 at Going Gear. I have seen it listed elsewhere for the same price, but claiming that is introductory and the regular price will be $39.95.

Would love to see how it tests against my petzl zipka

It will be interesting to see the beam.

The H01 should be tougher — it is dustproof, waterproof, and shock resistant (Zpika is just splatter-resistant — IPX4):

* Water and Dust Resistant to IP68
* Mil-spec: MIL-STD-810F

For another, I’ll be surprised if the H01 is not regulated (the iTP Ax EOS lights are), while the Petzl Zipka is not.

Weight, with belt & lithium battery = 58.4 gm / 2.1 oz, making it lighter than the Zipka.

>Weight, with belt & lithium battery = 58.4 gm / 2.1 oz, making it lighter than the Zipka.

Ah, ok. Makes sense, as it only uses one AAA, as opposed to the zipka which uses 3 AAA batteries.

But that begs the question, will it be "lighter" to use my petzl zipka or the iTP Light? again, pun intended.

Petzl zipka plus w/ 3 AAA = 65 g ~~ according to http://www.trailspace.com/gear/petzl/zipka-plus/

Just to be safe, I always carry 3 AAAs with me on trips with the zipka, so maybe carrying 3 AAAs with this light would simply be a better option.

Wow, I've become such a gram weenie.

Oh and what does this mean:

>Water and Dust Resistant to IP68
>Mil-spec: MIL-STD-810F

and this:
>For another, I'll be surprised if the H01 is not regulated (the iTP Ax EOS lights are), while the Petzl Zipka is not.

Weight …
Petzl web page has no Zipka Plus any more — it does show a “Zipka Plus 2“. That weighs 71 grams, including alkaline batteries. If you carry spare batteries, we should compare weights with one set of spare batteries. The following figures include lithium batteries (both initial and spare):
*) H01: 66 grams (50.8 + 2 * 7.6)
*) Zipka Plus 2: 82.1 grams (71 – 3 * 11.5 + 6 * 7.6)
*) the comparison would be worse for Zipka if I assumed alkaline or NiMH batteries

But that begs the question, will it be “lighter” to use my petzl zipka or the iTP Light? again, pun intended.

I presume you mean lumens:
*) H01: Low 1.5 lm (50 hrs), Medium 18 lm (4 hrs), High 80 lm (55 min)
*) Zipka: High 50 lm, they do not give lumens for other modes, and their time are not comparable (since they are not regulated)
*) H01 bright is brighter than Zipka.
*) We have not seen any H01 beam shots yet, so we can see how the two compare in the real world.

Oh and what does this mean:

>Water and Dust Resistant to IP68
>Mil-spec: MIL-STD-810F

IPXX ratings are dust and waterproof. See the Wikipedia explanation. In a nutshell, Zipka is resistant to splashing (IPX4), while H01 is both waterproof and dustproof (IP68).

MIL-STD-810F covers resistance to all sorts of things. The claim may or may not be meaningful — see this Wikipedia article about it.

and this:
>For another, I’ll be surprised if the H01 is not regulated (the iTP Ax EOS lights are), while the Petzl Zipka is not.

Oversimplified, regulation keeps the light output level as long as the battery is capable before then letting it drop off. Unregulated drops right from the word go. In the cases we are discussing:
*) Tikka will be 50 lumens initially, and then steadily dropping over the life of the battery.
*) H01 will hold whichever level you set it on as long as the battery is able to do so.

Petzl makes good headlamps, and many people like the Zipka. They either like the lack of regulation, rationalize it away, or do not know there is a choice. For others, that lack of regulation is a deal-killer. Those who prefer regulation can always turn to something like the Princeton Tec EOS or Remix Pro (or now the iTP H01).

How does this compare to an eos w/ rebel?

How does this compare to an eos w/ rebel?

If we are busy comparing lights, don’t forget the Fenix HL20. Also see Mark Verber’s flashlight info on his web page. He picks the HL20 as #1, with EOS being #2. (He has not yet included a description of the H01.)

Weight — assuming the PT spec’d weight of 105 grams with batteries is with alkaline batteries. If you carry spare batteries, we should compare weights with one set of spare batteries. The following figures include lithium batteries (both initial and spare):
*) H01: 66 grams (50.8 + 2 * 7.6)
*) HL20: 79.5 grams (49.5 + 2 * 15)
*) EOS: 116.1 grams (105 – 3 * 11.5 + 6 * 7.6
*) EOS is heavier than either, including one set of spare batteries. The comparison would be worse for EOS if I assumed using alkaline or NiMH batteries.

Brightness — comparing lumens and runtime — one will have to wait for beam shots to compare H01 thow/reach and spillage. Here are lumens and runtimes:
*) H01: Low 1.5 lm (50 hrs), Medium 18 lm (4 hrs), High 80 lm (55 min)
*) HL20: Low 4 lm (56 hrs), Medium 48 lm (5.5 hrs), High 105 lumens (1.8 hrs)
*) EOS: lumens not stated, except for max
…Low: 50 hours, Medium 10 hours, High 70 lumens (1 hour)

It’s hard to know just what that means — could be pretty comparable, with EOS having a less bright medium and HL20 having the brightest maximum.

Regulation: all are current regulated (good)

Environmental:
H01: IP68 (waterproof, dustproof)
HL20: IPX8 (waterproof, X=no dust rating given)
EOS: IPX7 (almost as water resistant, X=no dust rating given)

Note: I am not a lighting guru — the above information is just what I have gleaned from the Internet.

I just ran across a CPF posting on the H31 that I thought interesting. But first, a weight comparison — as I calculate it, the respective weights, including a spare battery for each (assuming Eneloop batteries) are:
H01 — 2.8 oz
H31 — 2.9 oz

The CPF posting says “I have been using the H31 for two weeks now, and IMO this is the best headlamp that I have ever used. Period.” (Follow the link for more details.)

The H31 uses a CR123A battery. If you prefer AA, its H51 sibling is due out shortly.
