Question: do these flash lights use rechargeable batteries?
Document: This will be a great light. If on the other hand you want a light for tactical use with your sidearm consider the P2XFURY which is 200 lumens brighter on high for short periods at the expense of the battery life but has the same low setting, I just chose the 6px pro because I primarily use my light indoors as an EDC light and overly intense lights are somewhat overwhelming for that purpose and just waste batteries. BTW got to love the SF switch...
Have a couple of Surefire lights already but not with dual output. Handy for when you need light but less intensity. Batteries last much longer. Excellent lights. A little pricey but you get what you pay for. If you need a little or a lot of light this is for you. Highly recommend.
It out shines and out performs my big bulky Mag Lite. Which goes to show, bigger is not always better. The Surefire 6PX Pro is the perfect size, very durable, light weight, and well made in the USA! I also purchased the rechargeable batteries and charger. If you're looking for a great flashlight that will last a long time...look no further...well worth the extra dollars you spend on it, and through Amazon.com I thought I got a pretty good deal.
I am a tactical firearms instructor and have used many of the 2x 123-battery powered lights available.Pros:Good quality.Rugged construction.Perfect balance of bright enough for tactical use, but not so bright it also blinds the user.Option of low-power beam for general use (map reading, etc. )Cons:The only con is related to the last "pro".
All of the Surefire lights are very high qualityon low 15 lumens the light will run for manyhours, and on high only an hour or so. But15 lumens is not really bright enough formuch, it would be nice if the low setting wassay 30 lumens for about 10 to 15 hoursinstead of 15 for 30 hours, that would giveenough light to do most things withouthaving to use the high setting. All in allyou can't beat Surefire's warranty andquality.
I got some new batteries and all was good.Great price on Amazon!
this is the first flashlight i've had that has survived 6 months at sea without giving me any problems. i've dropped this thing 30 ft onto steel deck plates and accidently dunked it in bilge water and oil and it's still going strong. the only caveat is that the batteries are expensive. i bought some rechargables that were less-than-reliable, but they got the job done. i'll have to try surefires rechargables.
This is my fourth Surefire flashlight (aside from ones I purchased as gifts for others). Fourth because the others broke? No way. Fourth because, despite their price, Surefire lights are so well built, so high-quality and so useful that I find more and more uses for them.
I like the 15 lumen feature for using in the house and other places where the light will be needed in close quarters, then when you need the &#34;Spotlight&#34; feature, the 320 lumens really lights things up. IT will light up my entire back yard area which is good enough for me.
Some of their other lights have just 5lumens on low, which is too low in my opinion. What I want on low is the kind of output of the 2D incs of yesteryear, just enough to walk around with. I would not consider the low great for getting up in the middle of the night to pee while camping, because it will still hurt your eyes once they are well adjusted.Over all I am satisfied with my purchase.
