Re: ZebraLight H502 X-ML
So, not to put too fine a point on it, there are no plans here for another 18650 headlamp. Maybe the H60w was the end of the line.
Frankly I don't blame ZL if so; who wants the potential of a lithium accident a few millimeters away from a person's brain?

You know mobile phones and a lot of modern devices also use li-ion batteries...

Re: ZebraLight H502 X-ML
That was what I thought too but we can't omit the fact that there have already been a few cases of Li-Ion batteries exploding in flashlights. Personally, I try to use batteries from AW which are known to be safe and reliable so as to minimize any chance of an accident happening.

Re: ZebraLight H502 X-ML
Correct. Li-ion isn't inherently dangerous. But with a cell phone, it generally isn't up to the user to find and purchase the cells and the charger as a do-it-yourself project; charge/discharge rates aren't generally a choice given to the user; and circuitry and battery quality are often tightly controlled by the device manufacturer. I'm aware that there are millions (or whatever the number is) of perfectly safe usages of li-ion to every venting episode, and venting episodes are rarely ever life-threatening. The risk is very, very low, especially if the user is moderately careful with a single cell 18650.
My post is more a question about the business risk-management calculations that ZL may or may not be making, rather than the inherent safety of the 18650. I'm not intending to go Off Topic on 18650s. For my part, I hope ZL DOES make an H601 or H602; I'd buy it! But I'm curious whether they're making a liability calculation at the same time, and if so, it wouldn't surprise me. Remember, it's an American company, with most of its product made in China, one of which is designed around a powerful energy cell that's not completely idiot-proof. Could you find a higher-profile target for litigation...I can hear the lawyers drooling. We Americans are not big on personal responsibility when something goes wrong; it's S.O.P. to sue anyone remotely involved in an accident that I myself may have caused...more's the pity.

Re: ZebraLight H502 X-ML
ZL's roadmap only goes out to Q1 2012. If there were no plans for an XM-L H61, ZebraLight would have responded negatively to HIDblue's question. Instead, he answered affirmatively, but with either a release date in mind that exceeds the timeline in the provided roadmap, or with thoughts of adding it to the roadmap later. The roadmap is, most likely, a fluid document.
(edit: However, any chatter regarding tort law may reduce the likelihood of said light - so
)

Re: ZebraLight H502 X-ML
This is such good news. I recently got a H501w, and love it....just wished it was brighter. I almost bought two (one for my wife to read with.) Glad I didn't cuz I will hold out for the new one.

Re: ZebraLight H502 X-ML
Hope the 502 reverts back to 501's small form factor and light weight. 501 is an ideal light for running, not so much for the H51. Really the 501 is as big as I would want to go for use running. Improvement could be made to the head band as well to minimise bounce. The straps should connect to a stiffer material that is then backed by a soft foam to conform to the head. This would distribute the force from the head band over a larger contact area.
Would rather see a push towards longer runtimes in a smaller package then more lumen output with large heatsinks.

Re: ZebraLight H502 X-ML
But isn't the whole point of the XM-L emitter that IS higher output ? Along with that goes higher current consumption, and more heat being produced, leading to a larger, heavier light with shorter run time. Not what I am looking for, but it may appeal to others
My preference would be for the same size H501 with better driver efficiency and more mid levels of illumination (and yes, I'm quite happy to have any disco modes shoved of somewhere in the UI where I won't come across them unless I want to)

Re: ZebraLight H502 X-ML
You wouldn't have to run the XM-L at full power all the time. Increased run-time with the lower modes will be nice. Higher efficiency rulz!

Re: ZebraLight H502 X-ML
But Higher output mean larger heatsink, therefore bigger and heavier headlamp.

Re: ZebraLight H502 X-ML
I found when working on something like an engine which is dark, while kind of huge for s headlamp, the H60 had the output I wanted. I think this will be lighter weight than that.
I have a feeling this is going to be a GREAT headlamp because it brings back the near field flood beam, with enough output that it will be really useful in all sorts of situations. It's about balance and ZebraLight seems to have a design sense that I appreciate and respect. I think they'll get it right.
...But we don't know the max-output yet. As I understand it, this emitter combined with a new optic will provide more of a floody beam like the first ZebraLights. I'm sure it will be bigger and heavier than those initial ones, but if it's only running on a single AA it's not going to be that big and heavy.

I agree. The H51f for me was a major let down, and I quickly sold mine. Compared to the beam of my much loved and used H501, it was not in the same league.
H502, if kept like the H501's beam, and small enough, is a must buy! That's right, must

The H502 dimensions:

The H502 dimensions:
- Bezel diameter: .9" (same as the H51)
- Length: 2.9" (right between the H31 at 2.6" and H51 at 3.2")
