Mr. Glow...do you have the Ultra?

Ken...I thought the difference betw. the Ultra and the Arcfinity (Arc) was more than a "slight bump in brightness" from the info on this thread. I understand the tint is sweeter on the LE.
 
Has anyone seen the Ultra leds to say they are tinted differently from the Arc LEs? I heard the Ultra Gs had hand selected LEDs. This may or may not be the case though.
 
If Frank shipped out the preorders as he said he was, than we should know very shortly.

<font size="2" face="Verdana, Arial">The "black dot" as a coating is very sturdy and is "self-lubricating" - in that it's very Slick to prevent wear of the + contact and prevent drag (uneccessary wear) when operating the light. It has a very smooth "feel" and also creates a "soft power" on feature, in that when the head is increasingly tightened, the light climbs up to maximum brightness.

The caveot to all these niceties is that even when fully tight, there is enough electrical resistance from the dot to cause excessive dimness - or as CMG describes it, "long life". Removing the black dot exposes the copper contact (that is then built up w/solder) and easily made my light over twice as bright.

If I recall my current flow readings right, it was 38Ma with dot and 90Ma dot removed..

I wanna see the show down... Original Infinity with the balck dot removed VS. the new Ultra.......

<font size="2" face="Verdana, Arial">Well said. I also would like to see this.
 
I am trying to remember...isn`t the amp draw on the Arc head around 200ma ?

Hello,

Just received the new infinity Ultra-G today. Been playing with it since... comparing it to my ARC AAA LE and the regurlar infinity (with the black dot removed). I didn't have a light meter or any sort of way to measure the brightness b/w the different lights, only what i can perceive with my own eyes.

I usually run the regular infinity with a 3.6v lithium and when comparing it to an arc LE, the two are very very close in light output. The differences can be told with a slightly bluer shade with the ARC LE. Still hard to tell a noticible difference between the two.

Now when I received the new Ultra-G from COUNTY COMM (great service & fast delivery btw) I didn't think there was going to be a much of a difference between the turboed infinity and the new ultra-G. I was wrong.

I started with the a kirkland AA in the ultra-G and compared the beam with the ARC LE and turboed infinity... they were all relatively close in comparison. (the new ultra's don't have the "black dot") A great step for CMG. Now, I remember reading that the new ultra-G and was fully regulated, so there would be no advantages in using a lithium. (in regards to light output anyway) However, curious as i was, I plopped a 3.6v SAFT AA into the ultra-G and...

With the 3.6v, light output was increased by a substantial amount. Quite a distinguisable differene can be made when comparing all 3 lights. (I didn't have a 1.5v lithium to throw in the mix, but it would be interesting.) The new Ultra seems to have a bigger hotspot and does a better job flooding a small room with light than the other two. I was impressed to say the least.

One thing i didn't understand though, was why the inner reflectorish part of the ultra-G was anodized the same color as the body. I understand that the Government issue was hard anodized, but i figured that if the reflector was still shiny, light output could be increased just every so slightly. (every little bit counts

) Speaking of which, was wondering if there was a way of removing/buffing off the green color?

Anyways, I'm starting to ramble now... But i just wanted to share some of my thoughts about the new infinity. If you guys haven't already, i would recommend heading over at countycomm to see if they have any more government issues. You won't be dissappointed. I have to say, this is a great light!

cheers,

Victor
 
The only way to remove the anodizng is to sand it off....
I did it to my regular (yellow) infinity and, it is a tedious job... You can protect the LED with a straw. I didn't bother to do so and buffed it when I was finished with the sanding paper. (not sure if this makes any sense, but the paper's coarse I used were 400, 600 and 800...)
Buffing the whole thing left no marks on the LED, and I ended up with a mirror-like shine on my reflector.
And a very slight improvement of brightness...
 
In your experiment with the 3.6V AA, the output increased over the Kirkland AA with the Ultra G but didn't with the Infinity? That would seem odd, though Lemlux found that his turboed red Infinity actually got dimmer with a 3.6V battery, possibly saturating the step up circuit or something. Seems that the Ultra G can take the increase- that sounds like the hot setup now..
Wonder though, does CMG recommends the use of 3.6V or is it considered overdriving it?

I would think you'd have a very hard time with the new finish if trying to sand it off the reflector- It would be a negligible amount of difference, I'd guess, so if it were me, I'd leave it intact and pristine!
 
I compared a half run down AA alkaline to a fresh L91 Energizer Lithium AA in the Ultra-G. To the naked eye, I was unable to discern a difference.

<font size="2" face="Verdana, Arial">How very true!
 
any run time issues with that 3.6 v lith?...ie is there a loss of runtime cos of the capacity?
 
The Ultra sounds very nice. I wish they had not anodized the reflector.

The Ulta should help CMG make up for any Reactor losses. A lot of our members will no doubt buy one of these including myself.

Wingerr:

My red Infinity brightened with the 3.6V lithium -- more so than with a 1.5 V lithium. I reported that it was still dimmer than my ARC AAA. I recently posted that my red Infinity is equal in brightness to a L.E.D. Club 3AA 4LED rd light with 3 1.5 V lithiums.

I've not yet tried a 3.6V lithium with my ultra as I, too, have noticed no difference between the brightness with an alkaline or 1.5 V lithium in the Ultra.
 
The anodizng of the reflector I was told was to make the light more salt air/water tolerent for our servicemen/women. Bare aluminum would not be condusive to that environment.
 
So -- IS this a regulated light? Anyone left one on and charted the brightness vs. time til it dims down?
