I think Al has a point here. He wants us (anche io) to think before we say something here. 🙂

It's not an official statement. It's just my personal experience testing SureFire products and reading countless reports, reviews, I.S lab tests and comparisons since day one in CPF.
I've never seen or read about a single SureFire flashlight or weapon light delivering less than the factory claimed output. Quite the opposite: they all seem to deliver more than the stated output.

Yeah... I am not comfortable with such inflexible and unscientifically-evidenced phrasing as "will have" and "minimum guaranteed".
I am more comfortable with a phrase such as "it appears to be the prevailing opinion/experience on CPF that SureFire tends to under-rate the lumen output of many of its products and that for some products the rating can be considered more like a 'minimum' rather than a representative average."

I just re read the web site it says "capable of producing 200 lumens".
I would be concerned about such advertising were it not SF and it's reputation on the line.

Thanks for all the good advice! I just dropped them a mail. Expensive international calls and time differences sure are problems. I do hope they can handle this as professionally as what was reported by many others on CPF.

Well im kinda bummed. I just ordered my light the other day only to get an email letting me know that their stock had run out along with Surefires stock and it will take Surefire 2-3 weeks to get some more out to them. So i should have an LX2 in about a month :sigh: Maybe my EDC-P7 will come in sometime soon since it was supposed to have been in a week ago? Man am I impatient! But I can say im extremely happy that the LX2 is EDC style (Low then High) 
All my other lights to date are "tactical" Style other than my twisty and let me be the first to say it get's old blowin 200+ lumens in your face off a white wall or snow with night adapted eyes I guess you can say im becoming enlightened.

OK I gave up on the LX2 adoration and got back to regular business. Today I cracked into it more than just putting 2 trits into the clip. There is AR on the lens and down in the pocket of the optic. Inside the build looks just the same as any other E series Cree.
I took off the lanyard ring but it can go back on if I need it, I probably won't.
I put a stripe of SOLAS reflective tape in the former lanyard ring space, looks nice and is recessed deep enough so nothing will ever bother the tape.
I opened the head and centered the emitter properly, throw increased a bit.
I also put a glow disk down in there and the fit is perfect, I think there are more OTF lumens now thanks to the higher reflectivity and the afterglow is impressive.
In the small bezel gap that these all have I put a 1/2 inch GITD O-ring in there before I put the head back together, it couldn't look nicer and does not stick out at all!
An A2 tailstanding ring is enroute as well, it will fit just fine.
I took a half hour walk with it on high after the tinkering and all is quite well. NOW this is really MY LX2! 😀 Tomorrow I will have to toss a pic up here.

Al,
While I understand your concern the box does state: Low-15 lumens, High-200 lumens. Are you suggesting that the clear statements made on the package are no real indicator of the actual performance of the light itself? If they are not to be taken as a guarantee, then what exactly is the point of stating a specific number (as apposed to a range, etc.)?

Looking forward to seeing the pics of your updated LX2.... Sounds interesting...
BTW, how did you recognize the LED was off center? Did you just look into the bezel or was there an indicator by looking at the beam? Both my LX2 appears center when looking down into the head directly at the led....

As with many ratings, they are indications of nominal performance rather than an exact value. There will be variation due to a whole host of factors.
Measuring light output is difficult enough for manufacturers. The rating is not given with the expectation that the customer will be able to measure it either.
Also, the way we see light makes it extremely difficult for us to compare light output even though we tend to believe we can.
Perhaps the most important issue here is that we as Flashaholics place very different expectations and importance on output ratings. We like to have details and specifics and can sometimes forget that companies are not set-up to meet our niche needs/desires.
The difficulty is that some companies do see CPF as a community in which they market their products and will target our wants and expectations. SureFire is a high-profile (and high-interest to us) company that doesn't which leads confusion and sometimes disappointment.
I realised a long time ago that lumen output ratings have little value in the use of the product - the light is either sufficient or too little/ too much and this measure of a flashlight is often difficult to separate from the usefulness of the beam profile.
The product is either suitable for the task, or it isn't. The only real way to know is to try it for yourself.
Sometimes the CPF community does discuss various uses for light rather than concentrate on the light itself. Often other online communities based on activities rather than products being used can be helpful in finding fit-for-purpose tools.

Fair enough, and I don't really disagree with the overall sentiment - but I'm not sure that this argument would hold water with any other product. For example, a customer won't be able to measure miles per gallon on a car under the same conditions as the manufacturer, but we'd still expect the published specs to be accurate and meaningful.
The numbers should allow a meaningful comparison between products, otherwise there's not much point in publishing them in the first place.

Well crap! :mecry: I just ordered mine on Monday and got an out-of-stock notice too, but they said they should have more sometime this week (hopefully they really will get some in this week).
Even better than being merely a Low/High or High/Low light, it gives you instant access to either level! :twothumbs IMO, this is the very best UI of any flashlight I've ever used (I love it on my Aviators).But I can say im extremely happy that the LX2 is EDC style (Low then High)

Just got my LX2 in the mail today! YAY!
Great looking light, love the new switch, and lucky me -- perfectly centered LED behind the optic.
It's morning here, so I've only had a chance to do some indoor tests, and unfortunately, I don't have an E2DL to compare to -- which is what everyone seems to be using as the benchmark.
**I did have a chance to do a whitewall test against the Nitecore Extreme on high (w RCR123), and the LX2 is significantly brighter than the Extreme on high! (Nitecore Extreme is rated at 200 lumens, and AFAIK Nitecore measures OTF?)**
Can't wait until dark! Will try and get some beamshots if I'm not having too much fun...

The spot on the wall was not perfectly round. There was an odd shaped spill emerging from one side of the hotspot. Looking down the optic things looked lined up but with a TIR is doesn't take much for things to get screwy.
Open the head on both sides by applying heat, remove the screws, mark one of your wires as + or -, unsolder the 2 leads, pop the LED and board from the sink from the back side, add acrtic silver 5 in good amounts after tidying the sink up and then put the board back down with the screws, then solder the wires back. Now you have to put the head top and bottom on and put it back on the body. Turn it on and take a look. From here it's just a process of taking the top of the head off and slightly moving the LED back and forth till you get it right and snugging the screws down. A little time consuming but it pays. Plus this is a great time to swap LED's and add trits or something GITD in the bezel. You could also add stronger LDF between the lens and optic if you'd like.

Play in the tailcap threads
When i press the momentary switch i can feel some play in the tailcap threads. Any proven way of fixing this? Anyone try a larger o-ring or teflon tape on the threads? Don't want to make it much harder to turn, but would like to firm up the action a bit. Thanks.

Teflon tape has always worked in the past as long as you don't cover the very end of the tube. I will go check now for you just to be sure.

the Nightcore is a one cell light, no?
If they can get regulated 200 lumens OTF one primary cell, that would be something. Remember many import lights claim "225 lumens extreme tactical!!!!" when they are only putting out 90-150.
Ah the wonders of marketing.

Re: Play in the tailcap threads
Go for it. :thumbsup:
OK tried it and it works just fine. Made my action really stiff but then again mine does not have any thread play.
Go for it. :thumbsup:
