For those that don't know, that's geek-talk for "it's really stinky when it burns".

Must be those long polymer chains.

Unspectacular with a single AA?! It's easily the brightest single-cell AA flashlight out there, LED or incandescent.
 
Yeah, what he said!
The LS puts out a lot of light in the "single AA mode" - i find it very useful. ARC is one of the few lights, or products, for that matter, which allow the user to set the desired performance level.

Quite true. But like with Surefire, you have to take along all this clutter to change the performance level. Hmmm. Wonder if anybody would like to see a dimmer switch?
 
Good point about the "clutter," but I just love the LS utility. I can't think of any other way to allow multiple battery formats without multiple battery cases. An expandable battery case doesn't seem practical.

About the dimmer, I'd like to see more features in the new LS and/or LS5W, but don't want to see the size increase much.
 
Oh, I'm in complete agreement. The new LS should be smaller, brighter, lighter weight, longer runtime, waterproof to 2,000 feet, with more features like a dimmer and momentary on, and most importantly, *cheaper.*

Sorry Peter. Couldn't help myself.
 
I'm SO excited to see the new Arc!!

Are we there yet? Are we there yet? Are we there yet? Are we....
 
Just received four first run Arc LS`s today that my wife had ordered
wink.gif
many months ago. Two white and two cyan.

Very, very nice! Thank you, Peter, for some truly spectacular flashlights.

I`m now retiring both of my original beta units, and will be using one of the new white Arc LS`s for EDC...along with an orange-red HD Arc LS (both with the 123 power packs), and three Arc AAA`s: white LE, green and turquoise EV.

Hey...it doesn`t get much better than this!

For those of you that have made the Newbeam conversion to your MiniMags....save the plastic cup the Newbeam came in! It makes a good end cap for those ARC LS battery tubes! Just cut the lid off the cup and presto...instant battery cover. Nice way to keep a battery in those spare tubes.

So Ted is your the #140 or the #146 I have? I am amazed on the difference between the 2 heads.
David which of these two is the more common one? The 140 has the more common Nichia color, sort of purplish, and the 146 has a very white color to it. The 146 is noticeably dimmer though.<HR></BLOCKQUOTE>
(edit) oops again, I thought I was on page 36 but I was on page 2! (d'oh!) I'll just let the following stand---;>P
--the ARC thread kinda slipped out from under me for a while there...-- ahh yes good ol' #146, it was very white was't it? Now you see why I posted at least once about not understanding what all you guys complaining about the various tints the LS's had..;> ) ..well, now #146 an LSS (Second)I guess, since I long ago sent it to Peter for replacement since it wasn't playing well with the 123 batteries..2 days ago I got the replacement; #209, and I am very pleased. Completely silky smooth turning, a seemingly more blinding light when I looked directly into it (my scientific test; 'it hurt more' ;> ) -- and plenty of travel after the light goes on (instead of coming on just at the very end of the thread travel)
The old bodies work with the new heads..and I'm not certain but I think what I thought was 'grit' in the threads causing some roughness on turning in the beta models, may have actually been the battery itself scraping the inside of the (old) bodies..I'll leave the final explanation of this to Mr. Gransee or another more expert than I to confirm...
Also got the KemKoted aaa, also flawless, so far...;> )
(Any one out there get 'ol whitey, #146??)
Brock, and all, if you don't get an answer from me in any particular post, feel free to pm or email me ;> )
 
One question for Peter G.:

How does the regulation / matching of the ARC LS electronic to the actual LS used work ? What I want to ask is if you do match them or not - if not this might be the reason / explanation for the quite different brightness results people had been reporting from ARC LSs against each other and against other LS torches.

To make my point clear let me give an example - LS1 does drop 3.3V to draw 350ma while LS2 does so (draw 350ma) at 3.2V and LS3 does draw 350ma at 3.4V - now does the ARC LS booster/regulator set the current or the voltage to the LS at your specified levels - if you set the actual current all three LS1,2,3 will be pretty much at the same brightness level while probably consuming different amounts of power - whereas if you regulate the voltage the light output will probably be quite different.

Let me add that I think my ARC AAA LE and ARC SLS are the two best LED flashlights I own (had to add the LED as the SF E2e is nice too) and that I´m just curious and don´t want to disrespect you or ARC in any way with this question.

One other question though - did you saw my separate email to you regarding those plastic holders ?

TIA

Klaus

Oh no, I may have damaged my LS. When I first got my SLS white, it was very bright, way brighter than the inova x5. One day I had it in my pocket and it was on for a long time because when I leaned against the chair I felt something really hot. So I took it out and let it cool. It didn't seeem bright anymore so I thought the batteries were just low. So when I finally ran those down, I put in a new set of batteries. But now it doesn't seem bright anymore. It's barely brighter than the X5 now. Did the heat damage the LED so quickly? Anyone else experience their LS dimming compared to when brand new?<HR></BLOCKQUOTE>
just reading over the string.....did any one answer bc's question? All I can say is that something similar happened to one of my Arc aaa's, it seemed unusually bright for a while, then went to very dim...then out, for good. Mr. Gransee of Arc Flashlight kindly replaced it, and will probably replace yours too, if you haven't sent it in and gotten it replaced by now already!;> )

No, they are presently not matched Vf to set point. That would require different PCBs for each ranking or hand soldering of each board. The next version will be current regulated which will improve consistancy- both between units and over the life of a particular battery change.

Seperate email about plastic holders? Sorry, I have no recolection, and can't seem to find it. My apologies, please post here or resend.

I will say that what customer service I have had has lagged a little lately because of the workload. Mostly heavy R&D. There is a light at the end of the tunnel though!

Carpe Diem,

How do you like your Cyan Arc LSs? I'm still anxiously waiting for mine. Any info would be nice.<HR></BLOCKQUOTE>

Hi LEDagent...

The two cyan Arc LS`s are very nice. The craftsmanship is flawless.

The LED`s are for all practical purposes a green color, with a diffused and round...but extremely bright...beam.

The green color is most evident when you compare the beam of the cyan LS side by side with the beam of the Arc turquoise EV AAA. Also, I was fortunate to buy Aragorn`s green Arc LS, and the color of that beam is pretty much the same as the cyan`s beam.

I have a cyan "second" LS, and that beam is a little more tuquoise in color, but not as round or diffuse.

I don`t have the ability to post any pictures, otherwise I`d gladly do so.

In any event, you`ll really like your cyan LS when it arrives. If not, I`ll certainly take it off of your hands!

Best wishes.
 
Thank you Peter for your explanation of the current ARC LS design - guess with the new regulation and the new HD 1W LS in the future I just will have to get new heads then - talk about addiction - did you got your license from the DEA on these LEDs ?

Here´s the email I sent to the MSN address

Dear Peter,

sorry to bug but the question came up lately if by chance you have some of those collimator holders available as spares - I´m talking about those black plastic parts holding the collimator optics on top of the LS and which you remove from the LS w/O to have them fit into your LSs - not shure if you are using the original LS w/O to use in the ARC LS so you would have those holders or if you are using the Stars or emitters only. I kind of remember in one of the very old ARC threads on CPF that you talked about how you were removing those holders so I thought you might have some and I just ask.

TIA

Klaus
