Howdy gang. You may recall my post about the L1 light, and it's low beam rating of 13 lumens as printed in their 2004 catalog, and "as confirmed by a SureFire rep on the phone this Thursday." Well here I go again opening that can of worms. But this time I have in my arsenal my very own experience with this light. Read on.........

Today, I had my first "hands-on" experience with any SureFire lights, at the store location of an internet reseller. All of the models I examined were beautifully constructed. I am impressed in a big way. Upon examining the "fresh out of a new box L1", I engaged the high beam in momentary-on mode with the end button, and then in locked-on mode with the twist of the tailcap. All internet posted and catalog printed sources rate this at 20 lumens. The L1 was about the same brightness as my ARC LSH-S light, which I had in my hand for this "A/B real time" comparison. This similarity showed me that the battery was new. The ARC is rated between 14 and 17 lumens. I very much like how both of the L1 switching mechanisms worked. So far, so good.

Then I engaged the low beam in the same manner. To my surprise, I was looking for the light to appear, and until I looked at the LED head on, I could not see anything, even when I shined it on my hand and shirt. Even though there were lights on, I should have seen "something." What a disappointment this was for me. When you guys say time and time again, that this is what you all have found, and that there is no way that the SureFire claim of 13 lumens is valid, it makes me wonder what SureFire's numbers game is all about. I would say that this low beam level is "almost unusable." This low output would explain their published 50 hours runtime, wouldn't it?

Now I am on the warpath again, and will re-question SureFire for an explanation on Monday. You guys have used figures of 1, 2, or 3 lumens as the low beam rating. My honest and final opinion, based on my own examination of this light, is that this discrepency is an example of persistent and dishonest advertising. The more that I call SureFire and get the same response from them with their 13 lumens figure, the more obsessed I become with making them re-evaluate a cross section of these lights in their QC department, and posting an amended specification for the low beam, "somewhere." And this can be done very easily on their website. According to the reps I have spoken to, their website is the only source of accurate and complete information, and that anything printed at any time is not in a finalized state and should not be used to make any buying decisions. It should be done on their website ASAP, for just this reason. I am not expecting them to republish any documents that have been released. They would not do this anyway. They have been more and more arrogant to their dealers, and I have heard many horror stories about how they promise shipments to them and then keep them hanging and wondering when the lights will be shipped. And the dealers in turn, keep their pre-order customers hanging as well.

Since I would not be interested in the L1, even if it had a 13 lumen low beam rating, and since I would like to own the soon to be released L2 with 15 low and 65 high outputs, I am very worried about whether either of those ratings are "exaggerated." And if they are, whether I discover it myself or from a number of you, I will resume my crusade with that light as well, and pressure SureFire to change their policies and ethics.

I know that my good buddy "gadget_lover" will get on my case about this, as he has in the past. But he has no grounds to defend SureFire on this issue. Let's get real, people. The human eye has the ability to distinguish the difference in light output between a 1 or 2 lumen source and a 13 lumen source. And I am very tired of hearing the argument about the bins, the lots, and the specialized picking of Luxeon LEDs. A company of SureFire's magnitude, can do better to tighten up the tolerances of their Luxeon LEDs' output levels? To expect the masses to accept 2 lumens actual, and imply that the Luxeon LEDs have variable outputs due to the imperfection of the intricate manufacturing process, is a continuing charade, and an insult to my (our) intelligence.

OK, does anyone want to spar with me, point by point on this issue? I challenge "gadget_lover" to resume the debate! For those who are tired of getting into this issue again, you can always ignore me. There are endless topics to discuss in the lighting world at CPF, to keep each of you busy for a lifetime.......... Enjoy the ride!

it is trange how much fuzz can be made over one little error in a printed number. and an error it is, we're all set on this.

if you really wanna get one Surefire's case about this, then you'd have to do the same with just about every other company that releases a luxeon light aside from Arc and Elektrolumens.

Edit:
but i do agree with you that companies should post true numbers.
 
If you'll do a little research, Surefire is one of the more honest companies when it comes to lumens output and runtime. Check out some of the claims from some other companies and then compare their lights and you'll see. One typo (maybe it is supposed to be 1.3 lumens on low) and you bash the whole company? Wow. Kinda harsh. I've used the L1 frequently and find the low output of the L1 to be quite useful. Try using the L1 on low in the dark, and you'll see what I mean.

You want a 13 lumen low output on the L1? What use would that be? The high ouput is 15 lumens, and a 13 lumen output would be very little difference in output or runtime. I think 50 hours of usable light on low on the L1 is very usable in some circumstances.

"I would say that this low beam level is "almost unusable." "

Heartily disagree on this point. This light level is perfect for working in the "real dark" where very little light is needed. I use it all the time to get up at night and check on things/use the bathroom. Just enough light to get around but not enough to cook the retinas.

As to it being 13 lumens, you won't get any argument out of me on that. My Lightbox apparatus, although not scientifically perfect, shows that the CMG Infinity is producing just slightly less light overall than the L1 on low.
 
It appears that english is not Luxlover's native language, and that he (or she) is simply asking the wrong questions and mis-interprting the answers. It's not a big deal once you handle the light.

I've tried to point this out to luxlover, but to no avail, so I gave up long ago. Heck, I like the L1, especially after modifying it for higher output. I don't defend any manufacturer, but I do look for reasonable explanations. The paragraph above is a reasonable explanation of why luxlover may be confused and why he's getting answers that don't agree with common knowledge.

A valid question and answer:
Question: What is the light output of the L1?
Answer: From a low of 13 to a high of 20.

100 percent correct and not at all the information that was desired.

Examining my L1's output more closely shows that the output on "low" is just a bit dimmer than my CPF 2003 Arc AAA, and on "high" it is a bit dimmer than, but comparable with my Arc LSHP-F. This is consistent with what I know about the SureFire L1.
 
True numbers are all that I ask. But based on how I am getting killed for my post by everybody and his brother, others may not feel the same, and do not wish to tackle this issue.

And yes, I will go after every company who manufactures a light that I am interested in, and posts false data to encourage sales. I enjoy the challenge of confronting "the big boys", wherever they may be! Where is all the fight in you people? If any of you have any involvement in the ARC Forum, you must have seen how powerful the members of CPF were when the hard anodizing process on hundreds of LSHs left stripes on them and Peter Gransee changed policy because he got a huge amount of negative publicity about selling them as first run lights? I don't mind fighting for myself. If I win, you win. If I lose, you don't care either way.
 
It would make no sense to have a low setting of 13 lumen if your high setting is 20. Without seeing the catalog I must agree that this is either a typo, or more likely a misunderstanding of a range of high output.

Edit: I should have looked at the catalog first. These are clearly low and high ratings. Surely a typo. This often happens if MS Word is used to prepare a docuemnt because they assign two very different charaters to the two - keys. They look almost the same in Word but not if exported to anything else.
 
Surefire may be one on the Big guys of lights, but I hardly think they are out to deceive anyone just to sell the L1. Heck you have a hard time finding one to buy if you wanted to.

The Surefire website doesn't give a Lumens figure for the L1 on "Low" and gives a Lumens figure of 15 on "High".

Surefire Website L1 information

The L1's "Low" output is useful for digging around in a pack at night, checking on sleeping kids or making a head call...but it's hell clamping the L1 between your teeth. /ubbthreads/images/graemlins/icon15.gif /ubbthreads/images/graemlins/yellowlaugh.gif

All of you SureFire loyalists are fantasizing about an impossible error. There was not, there is not, and there never will be a rating with a decimal point. You are trying to defend the company, and you are accusing me of bashing it. Today is the first time I held any of their lights in my hand. Until about February 14th, I never knew they existed. Look at any one of their catalogs. Can you see anything other than whole numbers in their specs?

I am wondering what would happen if the L2 was released, and their specs had something wrong with them? What if the 15 lumen spec was really 1 or 2 or 3 lumens? What if the 65 lumen spec was really 45 lumens? Would anybody apologize to me? Would people ignore my posts after that, because I embarrassed the shorts off of their bodies? Would people apologize to me in the form of a private message, to save face?

I am more worried about whether my $165 is buying an L2 light that has an actual 15 lumen low beam, and an actual 65 lumen high beam. That is all. I don't know where everybody has been, but my discussions with internet resellers of SureFire lights, from coast to coast, don't have many wonderful things to say about the company. What I am obsessing about is only the tip of the iceberg of what is going on there. SureFire is not interested in appeasing us. They have multimillion dollar contracts with the military everywhere they turn.

As for your recommendation to use the low beam in the dark, I agree and will do so at my earliest opportunity. I may have been hasty in my assessment of the output as being "almost useless." Any light that provides usable light for 50 hours is a gem.

For sure, when I saw the closeness of outputs in the L1, I immediately wondered why they would be so close. Then I started looking at many internet sites and noticed that SureFire posted the high beam rating and runtime, but conveniently left out the low beam rating even though they did post the 50 hour runtime. How can this be explained "to me?" I may need to put on a pair of boxing gloves, the way things are going around here! Who's next?
 
From Surefire's website:
[ QUOTE ]

Output/Runtime - High beam runtime approx. two hours with 15 lumens maximum output. Low beam runtime approx. 50 hours


[/ QUOTE ]

Unless that's changed recently, there's nothing there about low beam intensity.

I don't have an integrating sphere, so I can't measure lumens. But the mcd measurements are:
168,000mcd on "high" and 1,430mcd on "low".
Both measurements taken from 12" on a Meterman LM631 light meter.
 
I retract my statement about the low beam being "almost unusable." I was hasty with my assessment. It would bring me great joy, if such a low output level could serve a great purpose in a dark room.

I think that I have an analogy concerning the usability of very low light levels. My new Pelican SabreLite LED light is supposed to put out 35 lumens with new batteries. This output is great at 875mA and 3.56 volts (3.12 watts). But the output of the light at 280mA and 1.05 volts (or .30 watts), with what would be called "dead" batteries, is still very useful to me in the dark. I was amazed at this. I imagine that the batteries at this point have many hours left in them.
 
I think someone needs to get a hobby or something... /ubbthreads/images/graemlins/jpshakehead.gif Just think of what else you could be doing instead of beating this non-issue to a pulp. Just my opinion of course.

But please do us all a favor and don't mention CPF in your "warpath" rantings with SureFire's CSRs. /ubbthreads/images/graemlins/rolleyes.gif

OK,I'm a surefireholic but I dont like the L1. I got the A2 and for 1w LED light I got the LSHP. One of the reasons I didn't get the L1 is its low beam is not satisfactory to me.
 
I don't think the SF catalog was missing a decimal point.

I think it may have been missing a DASH.

As in 1"-"3 lumens...
