Thanks for the welcome Henk4U2 !

In a few years I could have a screw or pin in my hip, then I could attach something really heavy, like a car headlight.

Hello Steve. Welcome to this forum. I'm sure we can find something to attach to your other hip  ;D Ever considered a head-light? Maybe not on your hard-hat, but from the breastpocket of your shirt.

Flashlight Reviews / XTAR MAGNEMITE H3R Headlamp Review
« Last post by rookiedaddy on November 20, 2017, 06:30:25 AM »
XTAR MAGNEMITE H3R Headlamp



Reviewer's Overall Rating: ★★★☆☆

Summary:
Battery: 1 x 18650 or 2 x 16340 or 2 x CR123A
Switch: Electronic Switch
Modes: 6 Modes (Moon, Low, Med, High, Turbo, SOS)
LED Type: CREE XP-L V6
Lens: Orange-Peel Reflector
Tailstands: Yes
Price Paid: N/A (Retailed at US$69)
From: XTAR Magnemite H3R Headlamp
Date Received: 13th November 2017

Pros:
  • Good runtime
  • Instant access to Moon mode and Turbo mode
  • Good white tint
  • Strong Helmet Clip
  • Side switch is easy to activate
  • Fast 1A USB charging
  • Non proprietary battery support. Any 18650 LiIon battery, protected or unprotected, button-top or flat-top can be used.
    ^^ however, I do not recommend using battery with proprietary positive and negative contact point at the same side as the contact spring might risk creating a short.
  • Consider lightweight for its size
Cons:
  • No battery included (although XTAR is kind enough to include a unit of Protected 3500mAH 18650 for testing)
  • USB Charging cable hazard
  • Side switch is too easy to activate (I know it's one of the Pro, but hear me out later)
  • Turbo mode is memorized
  • Magnet strength is weak.
Some photos:








The model name is printed at the tailcap.


Features / Value: ★★★☆☆

Note that the battery pictured above is not included in the retail package, laid out is what I received from XTAR directly (I was holding the user manual when taking this picture, yes, there is a user manual included)

At a retail value of US$69, I do expect a battery to be included to sweeten the deal. XTAR H3R headlamp offers the convenience of recharging the battery in-light via the exposed charging contact located at the top of the head...

although an usual design choice, it still works but with a caveat. The Turbo mode does delivers close to 1000 lumens in my home-made lightbox. The manual says H3R will step-down to 60% brightness after 3 minutes on Turbo, but I'm glad and pleasantly surprise that it doesn't work/follow what was written in the manual. LOL!

charging in action...


charging completed...


Use with headband:


Use with included Helmet Clip:

this helmet clip is pretty strong, and also a first for me as I have never seen such a strong helmet clip.


Design / Build Quality: ★★☆☆☆







The build quality is consider above average. The anodizing is most definitely not up to HA standard (yeah, called me spoilt child of the SureFire HA finishes, I don't mind). Modes switching is stable via the side switch. However, when using together with the included headband, I found that the side switch gets in the way of rotating the headlamp as the only usable way to rotate is by grabbing the H3R by the head when rotating because if you grab it by the tail-end, the tailcap is easily loosen. This is a design shortcoming in my opinion.



I'm puzzle by the decision to memorize the Turbo mode when we can just double click in any mode to go straight to Turbo mode. It would be better to leave the Turbo mode out of the memory group in my opinion. The circuit reset will defaults to High mode upon turning on the headlamp after 10 seconds or more of open circuit (meaning no battery power provided).


With the push to provide flashlight and headlamp with recharging function, it is no surprise that XTAR has join the latest craze. However, with all the rush to push the product out the door, very few has manage to pull it off safely with fast charging. Given XTAR track record with huge line-up of LiIon and NiMH charger, it's no surprise that XTAR is among the first few that provided 1A fast recharging via USB. However, I was shock at the compromises made for the USB recharging cable. Now, H3R by itself is quite safe as I cannot detect any live Voltage nor current readings from the expose charging contact at the H3R head. But the USB charging cable is what I would call an electric hazard. There are live Voltage and ~1A current running through the USB cable contacts, it triggers the short-circuit protection mechanism of my USB charging station and powerbank when the USB cable contacts are shorted. I can't believe how easy and frequent this happens and this worries me lot. I have also tested with a USB power adapter without short-circuit protection, it allows ~1A current to run through constantly when shorted... needless to say, it easily lights up some steel wool too.

XTAR should really redesign or put some protection in the USB charging cable. In the mean time, I strongly advise users of XTAR H3R to immediately remove the USB recharging cable from your powersource once you are done recharging. I on the other hand, made a protective cover to "reduce" the chances of it coming in contact with any foreign conductive objects...



The magnet at the head charging contacts is good only for "attracting" the USB charging cable contacts. Don't expect to be able to use the headlamp horizontally while attaching it magnetically to ferrous metal surface because the weak magnetic strength cannot support the weight of XTAR H3R together with battery.


Battery Life: ★★★★☆
Although the user manual says that XTAR H3R will step-down after 3 minutes of Turbo runtime, in my test, it doesn't do that...

With XTAR 18650 3500mAH battery, I manage to get the Turbo mode to run for over 5 minutes before stepping down to ~80% of its initial brightness, and subsequently another drop to ~60% brightness at slightly over 10 minutes. H3R then continue to run at this brightness for ~1.7 hours before it sees another drop and it continues to step-down afterwards. After ~2.5 hours of runtime, it finally drops below 10% of its initial brightness.
Runtime on high sees ~3 hours of constant brightness before H3R takes a step-down, and goes a little longer than the claim 3.5 hours to drop below 10% output (10% of the claim 500 lumens)

I think this is a much better runtime behavior than other similar flashlight/headlamp where there is only a minute or two of extreme output (accompanying with scorching heat) before dropping to a more manageable output to sustain the runtime. But don't get me wrong, this H3R at Turbo mode do run hot at its Turbo too, it's just not scorching hot.


Light Output: ★★★★☆
My home-made lightbox gives the following readings:
Manufacturer       My measured lumens
53
6058
240239
500454
1000977
The above measured lumens are by no means authoritative nor an indication of over-stating the output by manufacturer. It's calibrated against some known output lights (e.g. Fenix, SureFire) so take it with a grain of salt and just as a relative reading.

measured current to be:
moon13ma
low0.11a
med0.46a
high1.04a
turbo2.4a


Some outdoor beamshots:
Moon mode:

yup, nothing much to see here...


Low mode:



Medium mode:



High mode:



Turbo mode:



and comparing to Olight's H2R output
Olight H2R CW High mode:



Olight H2R CW Turbo mode (accidentally shake my monopod while taking this pic, but should still be able to gauge the output):





Summary: ★★★☆☆
XTAR Magnemite H3R is a headlamp with so much potentials to be great... a 3 stars headlamp for now, hopefully they would incorporate more safety features in the recharging setup and make small changes to the Turbo memory mode (that is, don't put Turbo in memory). A circuit reset (battery change/replace condition) to Low or Medium mode is also a welcome change.


Is this a headlamp that I would recommend? Well, that depends on whether you can get a good deal on it or not (e.g. a free 18650 3500mAH battery included). The H3R headlamp is by itself pretty good discounting the hazardous USB recharging cable. So if you are getting this headlamp, I highly recommend that you use your external charger and ditch the USB recharging cable and reserved it for only emergency use if and when you absolutely needed it.

Hello from South Carolina, USA.  My wife & I live out in the country on part of an old farm, without a utility company supplied pole light (our part to save the planet). I am older 58 & play with electricity for my living by testing medium voltage switchgear, up to 80kv  :o.  I use a flashlight every day at work.  Right now that light is a Thorfire10s on my hip, & a Big Larry when I need my light to stick on the metal enclosure or Little Larry on my shirt pocket.

I was checking this Acebeam flashlight. But, its size is too big. I need the best 18650 flashlight but that should be compact. Please recommend your favorite flashlight name. My budget is $70. I don't waste money by purchasing junk flashlight.

Flashlight Collections / Re: The Bykfixer collection
« Last post by bykfixer on November 18, 2017, 02:12:59 AM »

E addiction continued to 4, but now I'm cured
I acquired an LED body for my Defender and have discussed with "Tana" a nichia 219 module that puts out like an original beam with 17 available configurations.
An olive drab click Executive and a natural finish clicky was too. The NA clicky will get a Tads setup, and the olive will stay stock-ish using a 6 volt Lumens Factory bulb.

Being it's mid November there's still time to add to the collection , yet there's nothing on my radar until Maglite releases the ML150 3C sized Magcharger number touting 1000 lumens. Eh, if I stumble across a 2 cell ML300 or an XL version at a local store I'll but those. But the SureFires might just be the last ones for 2017.....

Battery discussion / Re: Nebo Slyde King battery
« Last post by robo819 on November 13, 2017, 04:40:20 PM »
I am not trying to stir any arguments but , the Nebo cell looks like it works in the same way as a couple of other proprietary cells I have gotten in lights.
The little black ring looks like it is actually an insulator , keeping the Positive and Ground currents separated and if you use a regular button top or flat top in the light It will probably work (although I wouldn't swear to it) as far as operating the light , but it would not charge using the light itself as a charger for common cells , as they have the Ground portion of the cell covered with some type of insulator and only the positive portion exposed to make contact on that end.

One thing I would be afraid of  is (IF I am correct about this) is if you touch the center portion of that Nebo cell and the outer portion at the same time to a solid piece of metal , you will get a short from the 2 areas touching  as explained above with the center being Positive and the outer part of the black ring being Ground.

An easy way to test it is just take a very fine piece of wire , like a single strand from a piece of solder wick and touch it to both areas at the same time to see if the wire burns in half. This will act like a tiny breaker and will not carry the current more than just maybe a second , so no danger of overheating or a dangerous short using this method.

The second thing that would worry me about trying to use the Nebo cell in another light .......IF I am correct with my theory of the Positive and ground being insulated at that little spot where the black ring is at.......
Would be that some of the lights out there have the spring reversed , or upside down. By this I mean the little end of the spring is on the driver board and the big end of the spring is making the contact with the positive on the cell. With some of the larger springs that are oriented in this manner , you could possibly have a direct short , because the wider end of the spring could easily touch both the Positive and Ground of the Nebo cell , if it is in fact an insulator on the top of the cell dividing those 2 areas.

The last concern would be if you were to put the Nebo cell in an external charger , (again IF my theory is correct about the insulator) , with the top of the Nebo cell being flat , it could easily make contact across both Positive and Negative of the cell through the tab on an external charger.

A little long winded , but that's my 2 cents and my theory on these cells.

EDIT: I can not find a picture of the other end of the cell , but from reading a couple of things it seems this Nebo cell could be made with the Positive and Negative both on the "normally" Positive end of the cell and the normal Negative end of the cell is covered , or insulated?

The Nebo cell looks like a protected flat top. At $8, why not pick up a couple to keep on standby?

I'd venture to say the Nebo cell is nothing all that special in terms of propietary, just a low output protected cell more than likely.

My suspicion based upon the picture in the link I provided you with is substantiated by a customer review on Amazon. Please observe the black circle on the bottom end of the battery and read what this gentleman has to say about it  https://www.amazon.com/gp/customer-reviews/R270N3IB2U5856/ref=cm_cr_arp_d_rvw_ttl?ie=UTF8&ASIN=B01JRCR4P0
 
But then again: I'm always willing to adjust my perception if someone comes up with better definition of proprietary.
