Photon Freedom Review

Photon Freedom – The best button cell flashlight!?




Before I went AWOL, I had planned to do a review of this little flashlight.  To this day, out of all the keyring lights that run on button cells, this has been my favourite!  I have taken the Photon Freedom all over the world with me on various travels.  You can see here an example of a keychain setup I take for travelling HERE.  While the Photon Freedom is not overly bright, it's light weight, flexible, reliable and has a good runtime.  It crams a lot of versatility and hidden features into a very small package.

At the Grand Canyon


Pros:

-Great UI – has adjustable brightness levels that ramps up or down.  Gives you instant access to full brightness with a single click.  Or if you want to preserve you night vision, you can hold down the button and ramp up from low to high.  Sos/blinky modes are available, but tucked away for emergencies
-Unlike some cheap fauxtons, I haven't had any issues with it accidentally turning on.  If it does become a concern, you can set it to signal mode where it will only turn on whilst the button is pressed down.
-Comes with a neck lanyard and cradle for the Photon Freedom.  The cradle comes in handy as a way of storing the light that also prevents accidental activation.  See HERE for an example.
-Comes with a hands-free magnetic clip.  The magnets allow you to attach it to anything metallic.  You can clip it to things such as your hat, becoming a make-shift emergency headlamp.
-Quite a few hidden features/modes – will go into that later
-The ''white light version” uses 2xcr2016 lithium batteries – I feel these lithium button cells are better than the alkaline button cells in the streamlight nano/egear pico light.  I haven't done any objective tests, but I feel the lithium batteries maintains it brightness for longer.  They also work better in extreme temperatures.
-Comes with a life time warranty:  https://www.photonlight.com/pages/Photon-Guarantee-and-Warranty-Service.html
-Comes in a variety of colours (including pink!) and different coloured LEDs.
-Specs suggest 12hr+ runtime.  I wouldn't be surprised if this were true, but I would assume the later stages would be at a much, much reduced output than at the start.

Photon Freedom, hands free clip, neck lanyard with cradle.  The original quick-release clip is quite large.  I've switched it to a smaller mcgizmo clip (see above).


Cons:

-I feel the keyring clip included is a little too big – I've switched to a smaller mcgizmo clip instead
-I got a special version that is camouflage in colour (I don't think they make this style body anymore).  Aesthetics aside, this probably wasn't the best choice in colour, if you drop it in grassland it could be hard to find.  However, there is a “Doug Ritter” version that is bright yellow in colour, which should make it easier to locate when dropped.
-Very prominent PWM if not at max brightness.  But considering it's size and other features, I'm pretty forgiving of this.  Most of the time, I'd be running it at max brightness anyway.
-Not very bright (~5 lumen), but generally enough for keyring use, especially with a fairly fresh batteries.
-Beam fairly ugly, typical of most other 5mm LEDs.  Has a purplish tint and quite 'ringy'
-Costly compared to cheap fauxtons you can buy from many of the chinese electronic webstores

Camoflauge colour probably wasn't my best choice.  More difficult to see in nature environments


Photon Freedom hidden modes:


These were found in various threads in CPF and EDC forums, which I will link to at the end of this article.

Signal/morse code mode:
Keep clicking the button 5-6 times until the light only stays on momentarily. In this mode the photon freedom will only turn on whilst the button is pushed down.  To turn it off signal mode, hold down the button until the light turns off.

50% mode (potentially useful if you want to prolong your battery life using blinky modes):
From OFF Push until “first light” and then Release quickly. You can now Push & Hold until it reaches the level you would like. It will be using half the power as usual, so “full power” is 50%. This effects all levels and the blinking modes as well. You can check that you are using this mode by setting it to “full power” and waving it back and forth. In 50% mode it will look like a dotted line (strobing or PWM). In normal mode it will be solid. It will return to normal mode when it is turned off.

Demonstration mode (light turns off after ~6 seconds):
This is the way the light comes when new. You can also return to this mode by removing the battery(s) and then Pushing & Holding the switch as you put the battery(s) back in. In this mode none of the blinking modes will work, but all the ON/OFF and brightness controls will work. The light will also turn OFF after about 6 seconds. To exit this mode Push & Hold for about 20 seconds (till it turns OFF) or remove and replace the batteries without Holding the switch.

“Auto off” after 3 minutes:
1) press the button rapidly 6 times, which puts the light into "signal/morse code mode."
2) Then press and hold the button for about 5 seconds until the light goes out (this takes the light back out of "signal mode").
3) Continue holding the button for another 5 seconds until there is a brief flash of light.
-Now the light is in "auto off" mode.  At ~3minutes the flashlight will slowly ramp down in brightness until it is completely off.
-To return the light to normal operation without auto-off, Repeat steps 1 and 2 above without doing step 3 (ie. Let go of the button before that brief flash of light)






Conclusion:

If you want something small and light, and don't need more than ~5 lumens, the Photon Freedom is worth some serious consideration.  Personally, I like the brighter modes and nicer beam available with 10180 lights, so that remains my format of choice for a keyring light.  However, the 10180 batteries don't last very long on higher modes, so you'll need to recharging them relatively regularly.

This is why I like having the Photon Freedom as my keyring travel companion.  The batteries usually last the duration of the trip (provided your not TOO heavy with it's usage), and I don't need to any extra chargers that I'd need with a 10180 flashlight.  I'll often EDC an AA/AAA flashlight when travelling, so usually ~5 lumens is enough for keychain usage and an emergency backup to the EDC.

ABITAX 0510 Tag Light


This was another toy I came across in the New York MoMa Store.  Initially, I was hesistant to buy this keychain light, at $18 USD I felt it was overpriced for what it was.  Nevertheless, I ended up getting it anyway. 

The ABITAX tag light is sort of similar to the 'fauxton' lights, but what intrigued me about it was the design and smaller size.  Instead of two CR2016 batteries which are found in the fauxton/photon lights, it uses two smaller CR2012 batteries.  As a result this, the light is slightly smaller and very lightweight.  In fact, it's probably the smallest and lightest flashlight I own.



Size comparison.  From the top: Photon Freedom, ABITAX Tag Light, Egear Pico Zipper Lite
 
Comparing the ABITAX tag light to my Photon Freedom, the ABITAX is slightly less bright.  However, it does have a nicer tint which is more blue as opposed to a purple tint.   The beam also has less rings and artefacts than the Photon Freedom.  The ABITAX has a clear frosted section over the LED; I believe this helps to smooth out the beam.

LED is protected by a frosted translucent cover.  However, the centre area is not frosted.


To operate the light; you push the red button to turn it on momentarily.  If you want to leave the light on, you need to slide the red button forward.  I do find the side button a little too sensitive to pressure, and it is likely to accidentally turn itself on.

Another downside of this light, is that it's not waterproof. 

On the upside, the batteries in the ABITAX are easier to change than the photon/fauxton lights.  There is a small panel on the back, that can be slid open to change the batteries.  No need for screwdrivers or other utensils.

Panel on the back is flipped open to change batteries

Another thing I like about this light is the clip that it comes with it.  It's really sturdy, lightweight and well made.  I wish I could get more of these to use on my keyring.

I really like the clip that comes with this light!

 Overall this keychain light has a few shortcomings, but if you are looking for something very small that weighs next to nothing... it might be something to consider.

PINK STREAMLIGHT NANO REVIEW

PINK STREAMLIGHT NANO REVIEW





The LED light on my keyring is probably one of my most used keychain items.  I find a small flashlight comes in handy for those times you drop something in the car, or for opening the house door in the dark.

So obviously, I wanted to equip my wife with a keyring light as well.  Unfortunately she doesn't share my enthusiasm for flashlights and wasn't particularly interested.  If I had to subject her to having a keyring light, here conditions were; (a) it had to be something small and light weight (b) not too expensive (she doesn't want me to 'waste' money on something she doesn't appreciate).  Surprisingly she wasn't too concerned about aesthetics.

I've come across the streamlight nano in the past, and having seen a pink version, I thought this would be ideal.  She has since had it on her keyring for over a year now.


DESIGN AND BUILD

The elongated 'bell-shaped' streamlight nano is made from an aircraft-grade aluminum with an anodised finish.  The original streamlight nano comes in black, but since then, a pink and blue version have also come out.  $1 from the sale of the pink version goes towards the breast cancer research foundation, while the blue version goes towards 'concerns of police survivors' (C.O.P.S)

There's no mention of what sort of annodisation the streamlight nano uses, it does not feel very thick and I doubt it is HAIII. From over a year of usage on my wife's keychain, it's developed some wear on the edges and corners of the flashlight.  I feel this is normal wear characteristics for annodised aluminium... it arguably adds character.

The streamlight nano is one of the smallest keychain lights around, measuring only 3.73cm in length, 1.3cm in diameter at the head and 1.09cm at the body.  It adds minimal weight to your keychain, weighing only 10 grams.


The light is rated as being weatherproof, so if you get a few splashes on it, it should be okay.  It has a small o-ring to help keep out moisture and dust.

The streamlight nano comes with a clip that makes it easy to attach and detach the light.  The pink and blue versions also come with a FOB that features the logo of the institution it supports.  If you want to minimise bulk and weight, you can take the FOB off.

BEAM AND OUTPUT

The streamlight nano contains a 5mm LED rated with a lifespan of 100,000 hours.  This 5mm LED provides around 10 lumens of light, which is enough for lighting up objects at short distances.  Unfortunately like a lot of other 5mm LEDs, there is a blue-purple tint to it's beam.  The beam is also quite 'ringy' and has a lot of artefacts.



Beam at ~5 metres

Beam at ~0.75 metres

5mm LEDs have their limitations, they can not provide a lot of lumens like the 'CREE' powered LEDs.  However, the 5mm LEDs are more resilent and do not need a lens to protect the LED.  The LED itself can focus the light, avoiding the need for a reflector.  Both these last two points, help to reduce the size and the cost of the flashlight.

According to the streamlight specifications, the nano is meant give 8 hours of 'usable' output.  However this output is not at a constant brightness.  The streamlight nano is direct driven, meaning as the voltage in the batteries drop, the brightness will also drop.   So if you notice the light seems less bright with time, you may consider changing to a fresh set of batteries.


4xLR41 button cells on the right

Streamlight advertise this light as running on 4xLR41 batteries.  LR41 batteries are alkaline button cell batteries, they can be bought fairly cheap from internet sources.  If you are willing to pay a premium, consider getting the SR41; the 'silver oxide' version of LR41.  Silver oxide coin cell batteries tend to have a higher capacity than the alkaline equivalent.  They also have a flatter discharge curve and are better at providing a constant voltage.  To simplify... in theory, the SR41 should not dim as quickly compared to using LR41 batteries.

Be aware there can be a difference between SR41W (also called '392') and SR41SW (also called '382').  The SR41SW are low drain while SR41W are high drain.  Flashlights would be better suited for the high drain version (SR41W/392). 

You should also be aware of fake silver oxide batteries!  Have a read here  and here.


POTENTIAL ISSUES/CONSTRUCTIVE CRITICISM

One of the most common issues that people report with the streamlight nano, is the light has tendency to come apart by itself. The o-rings and threads provide little resistance to twisting, so it is not suprising to hear this happens. 

Some suggested solutions to this problem are:
-adding some telfon tape (the sort that is used in plumbing), around the threads of the light.  This creates more friction and resistance to turning.
-adding some sort of swivel to the keyring attachment.  This means when the light accidentally rotates, it will hopefully rotate at the swivel, rather than untwisting between the head and body.

I have read some complaints that the light is difficult to operate one-handed.  I guess this is one of the trade offs of having a very small 'twisty' flashlight.


CONCLUSIONS

If you are looking for something ultra small and lightweight, the streamlight nano is a good contender.  It's not the brightest light around, but it will do the job for short distance applications.  The pink colour would be popular with most of the female population... and maybe some of the male population to boot!  If you get a pink version, its nice to know that little bit of the money is going towards a good cause.


OTHER LIGHTS TO CONSIDER

There are quite a few button cell/coin cell lights around, with varying degrees of price and quality.  Some that come to mind are:

- egear pico zipper lite - I would consider this the direct competitor to the streamlight nano.  It's slightly larger as it has a battery carrier.  The manufacturer reports a longer runtime than the nano.  Comes in a wider range of colours
http://www.essentialgear.com/store/p/117-PICO-Zipper-Lite.html

- '2x2016 coin cell lights' - in this category are the photon 'micro' range, inova microlight and the cheapo 'fauxtons'. From this range of lights, the photon freedom stands out the most to me.  It has variable brightness control and beacon modes included.
