    Default Zebralight Summary

    Here's what what I've put together regarding the Zebralight H50 1AA headlamp. All information taken from posts to CPF.

    Zebralight ThreadsZebralight Reviews







    Zebralight H50 with GID bracket
    Zebralight H50 Prototype



    CAD Image with pocket clip

    Make/Model: Zebralight H50 1AA Headlamp
    • H50-P4: Standard Model with P4 bin Cree XRE LED.
    • H50-Q5: Limited Edition with Q5 bin Cree XRE LED. Production run limited to 90.
    Cost:
    • H50-P4: US$39 + pp.
    • H50-Q5: US$49 + $5 pp.
    Ordering:
    • Direct from Zebralight's website zebralight.com. From other dealers later. May be a sub-forum over at CPFMarketPlace later.
    • There is no pre-order list for the H50-P4.
    • A H50-Q5 pre-order list is here. List is now fully subscribed. (Update 8/9/07: those on Q5 pre-order list should have received a PM giving paypal details.)
    Shipping:
    • George @ Zebralight is said the H50 can be ordered and shipped from next week (first week of September). Message Link
    LED:
    • H50-P4: 1 off P4-WC bin Cree 7090 X-RE. (For first batch anyway)
    • H50-Q5: 1 off Q5-WG bin Cree 7090 X-RE.
    • Q5 bin: 107-114 lumens at 350mA
    • P4 bin: 80.6-87.4 lumens at 350mA
    • Q5 bin produces an average 32% more lumens than P4 bin (best 41.4%, worst 22.4%)
    Batteries:
    • 1 off 1.2-1.5V AA, Alkaline, NiMH rechargeable, Li-Fe (Energiser Lithium L91).
    • Li-Ion (14500) are not supported.
    Circuitry:
    • All levels output regulated (boost voltage/current regulated). No PWM.
    • Circuit is optimised for single cell (1.5V) operation.
    • The circuit can take up to 4.2V but is NOT supported due to heat buildup.
    • The circuit won't start below 1.1v. However, if the circuit is already on (>= 1.1v), it will work down to 0.9v.
    • If the light is turned off for more than 5.6 seconds, the light level resets to low.
    Performance: H50-P4
    • Low: 2.6 lm for 85 hr
    • Med: 13.0 lm for 19 hr
    • High: 65.0 lm for 2.5 hr
    • Runtimes performed using a H50-P4 model and a Sanyo 2700 mAh nimh battery
    Performance: H50-Q5
    • Low: 3.4 lm for 85 hr
    • Med: 17.2 lm for 19 hr
    • High: 85.8 lm for 2.5 hr
    • Output levels calculated from H50-P4 data x 1.32.
    Beam Type:
    • Flood, 120 deg spread.
    • Small TIR lens used. Most of the Cree rings subdued with the TIR.
    • The optic in the ZebraLight H50 does not do ANY collimation. It's designed to bring back as much as possible the original bare LED beam pattern, which is altered a bit since the LED is now recessed in the aluminum case.
    Length:
    • 66 mm
    Diameter:
    • 18.3 mm
    Form Factor:
    • Cylindrical
    Weight:
    • 17g without battery or headband.
    • 75g total weight, allowing 28g for NiMH battery and 30g for headband.
    Material:
    • 6061 aluminium body, Hard Anodised III (HAIII)
    • Hardened Lexan polycarbonate lens dome.
    Water Resistance:
    • IPX6 (TBC)
    Switch:
    • Twisty tailcap. Tailcap removable to replace battery.
    • Off, Lo, Off, Med, Off, Hi.
    • It will be difficult to operate with one hand.
    Headband:
    • The headlamp is mounted using a silicon bracket, filled with GID powder, to the elastic headband.
    • Headlamp easily detached from bracket to use handheld.
    • The emitter is off center about 27.6mm.
    Light Angle:
    • Headlamp rotates within bracket to adjust light angle.
    Other Models:
    • Planned Zebralight headlamp models:
      • H20 – CR2 (15266)
      • H30 – CR123 (17335)
      • H40 – AAA (10440)
      • H50 – AA (14500)
      • H60 – Li–Ion (18650)
    • After releasing the H50, Zebralight will consider manufacturing H30, H20, H60, and maybe H40.
    • The red LED or filter support will be in the Hx1 series. (Will not be released in 2007).
    • Release dates for these models are undecided.
    Modding:
    • The head is not accessible for any mods. It's sealed with heat conductive epoxy. Head bonded to battery tube.
    Accessories:
    • Pocket clip, Anti-glare device for glasses. Two extra GID silicon brackets, one with a neck lanyard.
    Warranty:
    • 1 year warranty against defects in workmanship and materials, provided that the product remains unmodified and is operated under normal and proper conditions.
    • Shipping addresses in the U.S. and China for returns and warranty services.
    Competitors:
    • Fenix are producing a Cree headlamp. Due end 2007/early 2008.
    Beamshots:



    H50 hanging about 16cm (6 inch) from a projection screen. Higher light level in the center is in part caused by the closer distance between the light source and the screen in the center. There are still some artifacts from the square die LED on the projection screen (or white walls).



    The beam is about 120 degree wide. You can see from this picture that the center area is not much brighter than the rest.





    taken with a 42mm (28mm*1.5) lens. the light beam is much wider than what my camera can handle.



    The hallway picture was taken with a long exposure time of 15 seconds at F8, ISO 640. The headlamp was set to High with some 83 torch lumens out of the front (or the side in the case of the H50).

    Humour:
    • Shakeylegs put together these lyrics as an ode the Zebralight. All together now...
    • To the tune of Money for Nothin’:

      I want my, I want my ZebraLight
      I want my, I want my ZebraLight

      Now look at them yo-yo's, that's no way to do it
      They’re wearin’ headlamps big as ATV’s
      That ain't workin', here’s the way to do it
      Lumens weigh nothin', ZebraLight’s for me

      Now this is workin', here's the way you do it
      Lemme tell ya, ZebraLight ain't dumb
      Got to get my Zebra its a little twister
      Want to twist that Zebra with my thumb

      I want to install lithium batteries
      Flood a campsite, deliberately
      We got to end this, procrastination
      We got to move these little beauties

      I know you really really really want to ship me
      My little Zebra, its only fair
      That mythic Zebra with the steel clip and the headband
      Oh George please show me it ain’t vaporware

      I want to install lithium batteries
      Flood a campsite, deliberately
      We got to end this, procrastination
      We got to move these little beauties

    Thanks a lot, have not even noticed the pic till now.

    not too sure on the beam without any focusing, will there (possibly) be a model with a floody reflector (15-20 deg.)?

    Thank you very much for putting this together, nzbazza. This is probably the first headlamp that I've ever been excited about.

    That is quite nice,
    I like the simple small design.
    Would make an excellent backup headlamp, and be great for reading etc.
    Bet you dont even notice it on your head.

    I still think the beam is gonna be off-center once you put that light on your head.

    It hasn't been released yet. Zebra Lighting is shooting for the end of the month.
    The shadows are darkest during the day.

    Same here. It's the closest to my idea of the prefect headlamp so far.

    i seriously doubt it... as long as its pointing in the same direction as your head... the few inches off center isn't going to make a difference...

    try it... take a SMALL flood flashlight... put it above one of your eyes (not in the center, but straight ahead) its still illuminating your target... the biggest problem MIGHT be seen when reading a map/book (really close work) on a low level...

    Looking forward to it!

    I don't think it will matter either. I used my Nite Ize headband along with my Fenix P2D and the fact that the beam was on the side of my head wasn't really that noticable. It still was lighting up what was in front of me quite well, and it is way more off center than the Zebralight is going to be.

    Great !!!!
    Finally a usefuk headlamp with a flood beam and small size on CR123 (soon)
    Simply cool.

    The pure beam of a Cree XR-E is very useful indoors and close range in total darkness. For those interested you can read the "Mule" threads in McGizmo's forum ... it is a flashlight with a pure Cree beam.

    There is a type of perfection that transcends the quest for lumens. Buying a $250 1-cell light for "lum factor" is like buying a $250 single malt Scotch for the alcohol content.

    Sorry, we have to have the head assembly potted because of space constrain and the way we 'squeeze' the circuit board into it.

    I've heard that the Lumapower LM303 has a floody lamp. Is that incorrect?

    I've added the LED bin information to the summary. WC looks like a neutral to cool-white along the BBR line, according to the binning d/s from Cree.

    If someone just made a universal plug-on mirror that directs the light 90deg sideways and somewhat diffuses it for close-range operation, many small lights could be turned into zebras.

    I gotta say that clip with the silicone thingie looks unnecessarily bulky and clumsy. I'd say just stick with a CMG/Minimag style slide-on clip made from springy metal.

    I suspect it's that way to prevent heat from being transferred from the body, to the clip, then to your forehead :-)

    +1. Just another thing to keep track of or lose. Either have it attached to the body or make it removable by having it slip on at the battery tube junction.

    I really like this little light, I wish there were a few more available so I could get on the list.

    I don't think it is meant to be used when the light is used as a headlight.

    I haven't been around for a while and just found the threads regarding this light. paulr- you must be happy I know you've been lobbying for a decent 1AA headlamp for some time, and this looks to be above and beyond. Regarding availablility- shakeylegs, do you have a link to the manufacturer's site? It seems that I've long missed the preorder.

    We are still developing the ZebraLight.com, which will be used as a information and shopping site.

    Regarding the availability, we'll have plenty of H50-P4s, the preorder is for the Q5 version.
