Input:
Question: What type of batteries do you recommend to use with this model of flashlight (SureFire Fury P3X Click Switch Dual Output LED Flashlight)?
Document: All the Surfire.com site says about it is &#34;Dual-output tailcap switch&#8212;press for momentary-on low, click for constant-on low, return to off and then press or click again for high&#34;. Umm, no I don't think so, unless mine is defective.Also, holding it in the manner it seems to be meant, through the middle of the fist, with thumb over the tailcap, does not work well for me.
What a sturdy very bright flashlight. I've had it for about 3 months before I wanted to review it. It is my first surefire light and I am very impressed with its build quality and performance. It is quite the thrower wow! It's like holding a miniature sun in the hand. It does use three cr 123 lithium batteries which can be spendy if you use this flashlight a lot. A great light if you want a lot of throw which I like.
Very nice light, like all Surefire lights. Just a note for anyone that would like this info, fromcandlepower forums.During the first three minutes of operation, the P3X uses step-down regulation to reduce output to 70% and settles at 50% after 30 minutes. Output is regulated at 500 lumens for 1h 45min, crossing the 10% mark at 2h 30min. Compared to the P2X Fury, the P3X has an extra hour of output at 500 lumens.
I do like the flashlight but would like it better if I could figure out the dual modes. I cannot for the life of me figure out the pattern if switching between low and high mode. It is NOT just simple matter of pressing it again to switch modes. Sometimes I go through 6 or 8 rounds of on/off before it will switch to the other mode. Other times it switches immediately as expected.
It weighs 7.2 ounces with batteries installed. While the P2X uses 2 CR123A lithium batteries, the P3X uses 3. It uses the same dual brightness system, with 1 press turning on the 15 lumen setting and a 2nd press turning on the 1000 lumen setting. Supposedly the batteries on the high setting will last 1.5 hours, however I noticed that the light begins to dim noticeably after about a half hour.
;  There you will find the Surefire Fury P3X in stock and for $175. I ordered it there at 3:00pm and it shipped out the same day.
While no one can deny the superb quality of Surefire flashlights, it's also true that no one can deny the superb quality and far superior features of its less expensive competitors. The P3X has only two outputs, high and low. The quality is decent, light output so-so (not anywhere near 1,000 lumens) and runtimes mediocre.
This surefire is perhaps the best flashlight I have ever used. While having one more battery (and thus slightly longer) than the P2X Fury, it has twice the lumens at 1000 compared to 500. Buy this flashlight over any other!
Good light worth the money. Very bright light love the dual output low/high setting. Comes in handy when 1000 lumens is not necessary! !
I bought a Surefire P2X Fury a little over a year ago and it was my first foray into high end flashlights. I originally balked at the price of the P2X (about $112 here on Amazon), but when I finally got it I was blown away by its build quality and brightness. When I heard rumors that Surefire was coming out with a 1000 lumen P3X, I started saving my pennies.
