Mine came today and wow is it a terrible blue/purple tint. My first zoomie to play with so I guess for $3 it is ok.
Easy to tear down - work from the bezel down, simple press fit driver. See the rough edge of the driver? That's what is a little flexible, easy to press fit in and remove. Yes, ol school budget modding 
Pretty much classic SK68, but that switch - might be better than regular SK68's, not sure. The switch's on the low budgets can kill the deal at times - difficult to replace with better low resistance parts, etc. OL used to re-build the switch from hand cut copper - a challenge for many.
I think KB is missing showing the plastic ring that holds down the LED/MCPCB - keeps it in it's place. On some of these I used to swap the LED/MCPDB and use some thermal epoxy to keep it down and dump the plastic retainer thing, which usually gets torn up from removing ti anyway.
Did any y’all happen to measure the diameter of the driver? Hell if I can find my calipers, and a ruler’s not terribly accurate…
Yep, Angry Blue™ with a touch of Hateful Purple™.
Yanked out the press fit metal retainer holding mcpcb down. Drilled holes into the rollo pill to facilitate removal, the bezel wouldn’t grip the o-ring enough to help and drilled holes into the plastic press fit switch retainer, it was pretty tight. Removed the mcpcb, popped the driver out. Easy Peasy…
Driver diameter 14.86mm Driver pocket in pill 14.82mm on my fine example.
Ahh, yeah - brings back memories... I got mine but didn't tear it down yet. Tailswitch is super stiff - just like the SK68's - don't think I fixed that before. Ohh, I see the drilled holes in the tail switch now - I've done that before too. The ZeusRay had a terrible switch, but at least they had the real thick shelf and decent LED, least at some point - quality was hit&miss.
Oh, bugger. So it’s not a 16, then. Wondering if I could just shave it down a fractional-mm and not kill it. Hate when They™ put hair-thin traces so close to the periphery…
Screw it… might just stick in a N×7135 dumb driver (ie, 1-mode, just hardwired 7135s and a diode) and not worry about it. It’d be a 14500-only light, no more alkaleak/NiMH support, but who cares.
Yes, that is what I will do.
Not marketed as a deal but this is a very good 4 port charger for 5.99, originally 9.99:

Olight X7R now a Lightning Deal. From $279 down to $209. I will pass but thought others might want to be aware.
That deal appears to have expired, but when I clicked on the linked Amazon ad yesterday, it appeared to be for the original version with the higher moonlight and unimproved tail switch, rather than the newer version with .5 lumen moonlight and improved tail switch.
I could find next to nothing on the PF04 in regards to reviews, just one video.
Even at the regular price of $14.99, it seems like a decent deal, if it’s a decent light. I’m tempted, though I don’t know if it would kick my Nitcore MT06 (now out of production) out of my pocket.
Yeah, it does appear to be the version with the 1 lumen moonlight. Which personally is just fine with me. :+1:
But I’m curious, how do the switches differ between the two versions?? What was upgraded switch wise??
I don’t know the details of the switch upgrade - I read some references to it in the Amazon reviews.
Most of the poor reviews referred to switch failure.
/\ . Thanks for the reply. 
Just got the silver one delivered today from the vipon deal.
Observations compared to my older silver PF04 ;
New one has more of a shine and almost a metal flake finish, older one is more like duller aluminum color.
Old one still has better creamy tint but have just come to realize it is just the tint lottery as the other 5 PF04’s that I have in different colors do not share that tint.
It is still a nice tint with no blue or green.
New one has wider spot/more flood. Reflector appears the same so do not know what the diff is, maybe focusing.
See no difference in the moonlight they all are nice and low and would venture that they are under 1 lumen,
Regarding the tail switch I have only had one with flaky switch and that was from over 1 year ago so whatever the issue was it was random.
The switches are still stiff and that will probably never change but they are usable once you are used to them.
These penlights are very nice for the money and remains my most used flashlight. 3 modes, no blinky, no BS.
I set up different heavy shirts for winter with a PF04, Reading glasses and a pen so the shirt is always ready to rock and roll.
Later,
Keith
Thanks for the PF04 rundown Muto, good info.
How does the head come off? What other emitters do you suggest to replace this XP G?I’ve got a XM L2 from a C8 that is less blue than this one.Would that work?
Extend the head all the way and keep pulling outwards while you unscrew counterclockwise (left). I think Kawi said his was too tight to do this (at least I assume this is what he meant), however, it worked fine for my light.
Thanks , I will give that a try.
Edit: Yup, that worked.
Unscrew the pill. Mine (pill) was tight so the friction between the head and o-ring on the pill didn’t work, when I tried unscrewing the head. The board is 15.65mm on mine, don’t have the pill with me it is at work, was going to make a press fit slug for it, but I think a 16mm board will work? So what ever you got on a 16mm board…I have yet to mess with the resistor on the driver, so I don’t know what the driver is capable of yet. On a 14500 Purple Efest I think I got like 60-80lms stock, IIRC?
Edit:
With the (1R5) 1.5ohm resistor 2” 22awg leads, I got .83amp High, .20amp Low and ,43amp Strobe measured at the emitter.
Jumped the resistor got 1.45amp at the emitter then went single mode. It did got thru the levels twice, then went single 
Now to wipe it clean and piggy back a 12mm FETDD driver…That I have had (a few of them) bought at RMM’s Garage Sale years ago…
