P1's in all it's glory: a small comparison and some thoughts.

I've always been a great fan of the Fenix P1 series, so much that my current EDC is the P1CE. Until today, when the mailman produced a package from fenix-store.com: a brand new P1DQ5!

Let's take a small look at what I have on this series:
P1 - 64 x 20.4 mm, Luxeon III, smooth reflector, black
P1CE - 67.5 x 20.7 mm, Cree P4, orange peel, natural
P1DQ5 - 71.6 x 22 mm, Cree Q5, orange peel, black
Small size is a constant, although it keeps growing. But even the largest one is a very small single-cell flashlight, very light, going unnoticeable on any pocket.

Relative brightness order:
Q5 low - P1 - P1CE - Q5 med - Q5 high
I was amazed to see that the Q5 medium mode is brighter that the P1CE. When white-walling the beams, the Q5 going from med to high seems brighter, but not by much. But moving outdoors, the difference in throw is truly amazing.

Beam quality:
P1 - smallest spot, widest (although weaker) flood, very smooth, with a hint of yellow. Very nice.
P1CE - wider spot, smaller flood, but better distributed, very smooth, also hint of yellow. Highly usable.
P1DQ5 - beam shaped like CE, but cree dark halo still noticeable at short distances, despite the orange peel. Whitest beam of the bunch. Almost perfect.

Smoothness of action:
Outstanding on all three, very easy to operate with one hand, even for mode switching. The first two have foam pads, Q5 has a spring at the bottom.

In use:
Even the standard P1 is a great user, providing more than enough lumens for 95% of my EDC needs. When I upgraded to the P1CE, I was bordering on more light than I need, but since runtime was the same... Now with the Q5 I still have the simplicity of use, a great twisty on a very small form factor, with some cards up the sleeve: lots of lumens on high, which I doubt I will ever use, and lots of runtime on low, qualifying this light for some emergency scenarios (and bedtime reading). Strobe and SOS are just futile, but being last on the cycle, I'll just forget about them.

Something strange about runtimes, a few weeks ago I did a full run of the P1 and P1CE with freshly charged AW protected 3.7s, and the P1CE ran for longer. The brightness increase compared to primaries was great, but the runtimes were quite disapointing.

Nevertheless, with primaries, runtimes are enough to last me a few weeks of standard EDC on one battery. Considering that I rotate frequently, and that at home I use rechargeables in other flashlights, each cell on a P1 variant should last me quite a while.

The P1DQ5 is a definite improvement on my previous P1's, and I reflect this with folders I like to pair my flashlights with:
P1 - Benchmade MiniGriptillian (154CM)
P1CE - Spyderco Endura 4 Wave (VG10)
P1DQ5 - Spyderco Military (S30V)

If you mod the P1 with SSC, you get this nice hotspot/corona, almost So17x like, without the definition between hotspot/spill

That should be great, but I don't think I'm up for the job. Never modded a flashlight before, and couldn' risk ruining mine.

But... any way to find a how-to?
 
Need bare emitter, arctic alumina glue, solder and iron, heat and 2 thick leather padded vicegrips. Heat up head and twist apart, then de-solder leads. Scrape off old emitter, clean up glue spot. Solder leads to emitter first then attach to heatsink with alumina while centering. Reverse can cook led while trying to gain enough temp to overcome heatsink and melt solder. Leave head open while curing to prevent lens fogging. It has worked for me well. Hope you get it centered properly, it can be tough. Try the old strings across the top method and mark the spot where they join with a sharpie.

I have a P1 CE and I am thoroughly impressed every time I turn it on. The small size and big output make it a great pocket light.

What was the runtime you got on a primary for your P1 CE? Does it get hot? I haven't used mine for extended periods. Maybe a couple of minutes at a time.

When my P1 drops out of regulation it falls hard. It must drop to under 3 lumens within 5 minutes.

Copy from my post elsewhere:

"Some time ago I got four AW Li-ion 3.7 protected bats (750 mAh), and an Ultrafire WF-138. They have been through no more than four or five cicles of use.
I've been using them with good results to power up my babies, but today I did a more exhaustive test: fresh charged bats, dropped onto these lights, with the following results in runtime:

SF C2 with Lighthound Cree drop-in (750mA): 1h04m
Fenix P1 CE: 0h55m
Fenix P1: 0h43m

I know that primaries would give less lumens but more runtime. Even so, the times I got were quite low, even for guilt-free lumens."

I haven't run them to the end on primaries (only have a couple left, and no light-meter), but from what I've seen here on CPF, an increase of a little over 50% should be expected. I guess with primaries, heat will not be an issue. Running 3.7s gets them a bit hot, but still manageable.
 
As of Today, I have EDCed my P1D for a year. Used it for about 20 minutes today working on my truck. It still works like the day I bought it.
I love this light.
 
The P1 is STILL my EDC. I wear a business suit to work everyday and I carry a P1 in a holster that rests behind my (tiny) cell phone. It just disappears! I LOVE the thing, even if I have a bunch of higher-powered lights. Now, it does not replace my DBS/A9/MRV for serious stuff, but as an emergency backup in the workplace (and at home) it STILL rules. Great beam from that Lux III too.
 
Will Fenix ever make a P1 CE Q5 (or higher bin), keeping the output around 90 lumens and using the improved efficiency of the emitter to extend runtimes? What a light that would be!

I too waiting for P1CE Q5... *crossing fingers* I really hope Fenix produce it. Keep the 90lm, that's really bright for many jobs..just extend the battery life.
