I have had an original run of the Xlight that I got at the 2006 SHOT show. It was given to me by the folks at LRI. This was before they were on the market. It has been on my keys since with no issues.
Just remember it is a keychain light and is not meant to be bombproof.

As far as water-proofing don't bother; lights that run on low power don't need to be waterproof. Just turn on a photon and toss it in a glass of water it will keep working.

You can get cheap batteries from here:
http://www.dealextreme.com/details.dx/sku.832

You can also get keychaing flashlights (Photon knock-offs) for less than $0.50 at the same place:

It does take close to a month to get your order, but the stuff is coming from Hong Kong. They are not the absolute best quality, but they are great at geocaching goodies.

I also carry an X-Light on my keychain. I decided to remove the Arc-AAA after the hard-anodize finish wore off the ridges on my keys. It actually killed one of my car keys. After that, I decided that a plastic-body light was the way to go for keychain use. I **LOVE** how the light is dimmable. This is a great feature for those worried about battery life: only use the power that you need.

I had a problem with my X-Light recently. I found that ONE of the two batteries had died. My guess is that the bottom battery shifted and shorted out against the "spring riser" battery contact. Fortunately, I had over a dozen 2016's lying around and was back in business in no time. I could probably rig a permenant fix with a bit of tape, but it didn't seem worth the trouble at the time.

I use a CR2032 (3V) in my X-light and its still fairly bright. Someone mentioned the runtimes were greatly increased as opposed to using the standard two cr2016's so I'm trying it out. Plus I use mine as a night camp light so I don't mind it being 50% dimmer.

I did not know you could use a 2032 in an xlight. Good to know thanks.

You can even put a lithium rechargeable 3.7V 10440 battery in to the Fenix LOD CE to get an absolutely astonishing 120 Lumen output from the tiny AAA flashlight. Thats more than the Surefire M600A Tactical flashlight output.

Does anyone else here wish they had a little more education in the electronics field?

You mean I could have bought the EOD instead of the P2D-CE, and saved $15??

I'm pretty sure the P2D CE has much longer runtimes. A CR123 I think has a lot more capacity than a AAA size 10440. Please someone correct me if I'm wrong.


Bentirran, isn't the max imput voltage on the LOD CE 3.3V? That output is pretty amazing but how long can it maintain that level of output without damaging the led?

Yes the P2D CE will have much longer run times. A typical CR123 has a capacity of about 1200 mAhrs and a nominal voltage of 3V. A AAA sized 10440 will have a capacity of about 300mAhrs to 500mAhrs at 3.7V. Therefore the run times would be (1200x3)/(300x3.7) = 3.24 times less. The P2D CE in turbo mode runs at 135 lumens for 1 hrs. I would therefore expect the Fenix LOD CE with a AAA 10440 cell to last about 1/3 of an hour or about 20 mins.

The LED in the LOD CE is identical to the P2D CE both being Cree 7090 XR-E LEDs. Therefore the LED in the LOD CE is easily capable of out putting 120 Lumen. The driver circuit (pulse width modulated) may be different but I suspect that Fenix would have used the same driver MOSFET as the others in the CREE series to keep costs down. I wouldn't use the LOD CE with the 10440 continuously as the smaller LOD CE would have a greater problems caused the heat generated by the LED. The Fenix store website states an input voltage of 0.8V~3.3V although the thread on
http://www.candlepowerforums.com/vb/archive/index.php/t-149453.html
indicates that it can be used OK. In operation I would turn the power down if the little LOD CE gets too warm.

A note of caution though, the 10440 cell is unprotected and care has to be taken when charging and discharging the cell. Short circuiting the cell would also have a fire hazard. (or depending on your viewpoint another survival means of starting a fire)

Oh the P2D CE is a superb flashlight also and I would consider it to be much more flexible in use than the LOD CE for general use. It can give nearly 32hrs use at a similar light level as the Photon X-light and nearly an Hours use at 135 lumen (greater output than the Surefire M600A Tactical light). Its just too large for my PSK.

Tyrell to Roy

The light that burns twice as bright burns half as long - and you have burned so very, very brightly, Roy.

I agree. It almost made complete sense to me (that's a small joke) The P2D I bought is sort of a first step into EDC of a flashlight for me, besides the Fauxton on my keychain. I really don't need it for much, though. I think it'll also be my 2nd flashlight while camping. I discovered, after being followed by some creature for 15 minutes, that I'd like a light with longer reach than an LED headlamp. crazy
