I like the concept of the A2, but I have one problem with it. It is an incandescent and the bulb WILL burn out. Then there is the price problem. Why would I pay $160 for it, if I can get the L4 for $125 and the L2 for $165. I wont ever have a bulb problem, and Im sure they have a greater light output.

Tom,

Obviously, you wouldn't buy an A2. There is no single best light for all people and all uses. It's a matter of personal taste and the use to which you put your light.

Let me answer your question by saying why I bought the A2 over an L2 or L4. For the record, I have never seen the light output from either the L2 or the L4, but I own, or have owned, an Arc LSH, and a FireFly Mk 1 with TW0J lux III, and I have spent a good bit of time with a Lion Heart. So what I'm saying is that I have experienced good LED beams; I know a little something about LED light. And in fact, I think I know enough to know that I personally prefer incandescent beams. I have complete respect for people who prefer HID or LED. I think I understand why they do. Part of the reason I like incans, I think, is because I routinely need lights with penetrating, good throwing light, and especially lights that will cut through ambient lighting. In my experience, LED beams, lumen for lumen, are not as effective for this task.

Another reason I like incandescents is simply because I like the quality and type of light from a GOOD incan. I don't mind that the light has more yellow and red. In fact, I like it (as long as it isn't the crappy urine yellow of a bad incan). Maybe it's because I grew up with woodstoves and fireplaces. Not sure. But for whatever reason, I see things better with an incan, especially outdoors. The colors come out better and things are more distinct. YMMV.

And yes, the bulb WILL burn out at some point. And yes, bulbs CAN break when dropped or knocked. These are clear downsides to incans. But I think people over-emphasize these things. I have NEVER broken a filament on an incandescent light, and I have not yet burned out a lamp on one of my production lights, A2 or otherwise. And my A2, E2e, M6 and stock TL lamps have seen quite a bit of use. I did blow an MN20 within the first half minute of use, but that was defective, and SF replaced it free of charge. Count it if you want, but either way it adds up to one thing: I am so not concerned with my incan lamps burning up or breaking. If it happens, I always have a spare on hand.

So there it is: these are the reasons why I went for an A2 over an L2 or L4.
 
I respect your views. I have 2 Luxeon lights and 5 Incandescent lights. I use Incandescent lights when I do manhunt or am trying to see something far away.

I do NOT hate incandescents. I just dont understand why get the A2? Why not the E2e?

You are right with outthrowing them. Your A2 will kick their @$$, but the light output is different. The A2 immits something on the order of 50 Lumens, compared to the ~80 lumens coming from the L2 and L4.

My G2 and E2e will outthrow the A2. The have a higher Lux, I think.

Is the A2 bulb really regulated??

The E2e will certainly NOT out-throw the A2. As for the p60, I have never done a direct comparison.

And, yes, the A2 bulb is regulated. Why? Is that hard to believe or something? Regulation for LED's is all over the place, and designing a regulator for an incan is actually MUCH easier and it can be made significantly more efficient. Something like 98 percent vs. 85 percent, IIRC.

As for the L4, SureFire quotes it at 65 lumens. I just checked.
 
Cornkid,

The A2 is clearly better for me than the E2e. Everything is better, but the main reasons are as follows:

1. REGULATED. I hate that nagging feeling that my E2e output and whiteness is failing. I would be constantly wondering if I should change out the batteries.

2. LED's as well as incan. If I do run out of incan runtime or break or burn out the lamp, the LED's will run for a very long time and provide me with emergency light, should I need it.

3. Two levels of light instantly accessible (sort of a part b to the above): I find this to be so very useful.

4. Fits so much better in my hand. I actually like that it is longer. It carries better in the pocket and clips better on the belt. The grip is just right. My hand likes the A2 a lot, but only tolerates the E2e. It's too short. A clicky would help matters, I'm sure.

Those are the main reasons, but the E2e is one fine light as well. It's just that I like the A2 better, and that's saying a lot.
 
I see. I now understand. How the HECK did Surefire get an INCANDESCENT to be regulated? Thats unbelievable. I have never heard of a regulated incandescent. WOW

-tom
 
That is the reason why the A2 is so sweet. I have an E2e-SG and I hate the fact that it dims down. I was looking for a regulated solution, and the only add-on for the E2e-SG is the KL4, and it doesn't even match its color. Now, if Surefire came out with a regulated MN03 lamp, that would be my conversion of choice for the E2e.

The A2 offers all the benefits of the L2 to those with a preference for incandescent lights. It's good to have a choice. Wish I could handle an A2 myself in person.. oh wait, I'm not supposed to spend money /ubbthreads/images/graemlins/grin.gif

PS: regulated incandescents are possible. Willie Hunt's LVR regulator for incans is sheer magic. Now if only I could get a regulated Mag85 /ubbthreads/images/graemlins/grin.gif

I am also building up a collection of LED and Incan lights and have seen a bunch that I dont have. You reminded me of the Pila GL3 passaround that I happen to have right now.

Last night I ran it as a ceiling bouce to light up my room while web surfing. (because that what we flashaholic do /ubbthreads/images/graemlins/smile.gif ) And the light was sooooo much nicer than the standard LED lights that I normally use. Really warm and a LOT of lumens for a while. didnt do runtime cause I was already doing a runtime on another LED light. GL3 did get pretty dang hot, which I noticed when it suddenly went out after what seemed like a hour and I went to grab it. Kinda surprised me. I guess that is why it is so heavy with the thick metal but yet elagent. Not like the Nuwai 5watt I just say yesterday. (tank comes to mind)

Anyway, it's worth a look since the light is still going to a few places in the USA. KLM is next. You can find the thread in the passarounds section. /ubbthreads/images/graemlins/smile.gif

Yeah. The reason regulated incans are rare is simply that incans can easily get along without it. They are inherently stable in that way, whereas with LED's you have to be careful with direct drive. You can easily get into an unstable, runaway situation and fry your LED. Or so I have read, anyway. I've never done any LED experimenting or modding.

But the truth is that the incans are easier and simpler to regulate. Why? Well because they don't need a constant current. Think of the lights in your house. The current is dropping to zero 120 times a second and reversing direction 60 times a second, and yet you don't notice it. Why? Well simply because the filament will continue to emitt light as long as it is hot, and it doesn't cool down instantly. It has a "thermal mass", if you will. So as long as the switching is very fast compared to this time, you don't need to smooth out the output to make it DC (or nearly so). Fewer regualtion components, fewer losses.

You know, for a non science guy like me you just made this very understandable. Thanks. /ubbthreads/images/graemlins/wink.gif

I like the A2. Don't have on but one of my daughters, Carolyn, boyfriend has one. I did a light off ceiling with it, and compared it to a G2, using my LM631, and the A2 produced more light output. I like the regulated feature, and would like to be able to have the option to stuff a LiIon in one, for guilt free hours, as I tend to run my EDC's quite a bit.

Bill

Thought about lower output of G2. It had probably been run a whole 5 minutes, prior to testing, and had lost it's edge over the A2

Bill
 
I was wondering, what if the bulb does blow out? can u just buy another bulb, remove the lens and put in a new one? also, will liion batteries work in it? if i could get cr123 rechargeable to work in it...i think i'd b completely happy
 
Lets also remember who the A2 Aviator was designed for....air crews! The FAA requires the members of the air crew to have in their flight bags a flashlight equivalent to a 2D flashlight. The incandesent is used for preflight checks of the exterier of the airplane and the LEDs are for use inside the plane....LEDs are low enough level to preserve night vision.
 
Regarding that A2 my daughter's boyfriend has. She just dropped it by. Xenon bulb is burned/broken. Filament is hanging vertically. her boyfriend is hard on lights, and probably dropped it, not sure. I checked for her, and bulb is $25.00 + shipping at Surefire web site. I am going to check a store in Santa Rosa that specializes in Streamlights. They also carry some Surefire iteme, and carried more before Surefire got tough with their dealers, price wise.

Bill
 
The lamp on the A2 is easy to change if one blows or breaks. Unscrew the head (NOT the bezel), pull out the old LA, and install the new one. The LA installs from the rear of the reflector. The head unscrews where the octagonal section and the body meet. i.e. at the begining of the clip.

I have no idea if there are Li-ions that will work in the A2. Sorry.
 
I've been using mine for a while now and haven't had a problem, but I try to stay away from butterfinger moments, or at least try to have an LED when I'm slippin. .
 
You might try checking with Somelamps here on CPF...he seems to have every possible SF lamp or bulb....
 
The A2's led output is listed as 3 lumens.
For comparison anyone know what the
output (in lumens) would be for a Photon Microlight
w/ 2 CR2016's in it?

Thanks

MB
