Let me start off by saying that, regardless of it's obvious runtime shortcommings, I am definately going to get this light. Although, i am going to wait until dealers have them in stock. Judging from past Surefire sale prices, it looks like the prices will not get any lower than around $140. But i don't mind, i believe it is work the price, considering the technology involved.
Okay...here are my questions.
After seeing and reading the reviews, graphs, pictures, and color temerature measurements, I still have a few questions about the A2's functions.
Here is the critical data i have seen so far.
General A2 vs. E2 runtime comparison
Graph of Runtime
Color Temp:
A2: 3200K
E2: 3100K
This data, for me, give me the closest interpretation of an A2 without actually owning one.
But after reading the Surefire 2003 catalog, it says that, due to the regulation properties of the A2, "the Aviator's microprocessor saves enoegh power from the batteries to still run the LED's, even after they have been depleted to the point that they will no longer power it's incandescent lamp. Plenty of energy remains to power the LEDs. for MANY MORE HOURS, thanks to the peculiar property of LEDs..."
Having read this straight from the catalog, and not seeing this consistant with the online reivews, it makes me question if this is true...so far i don't think that it is.
From what i've heard, the LEDs stay on with the incadescent bulb. And judging from the light comparison picture (pic.1), I'm getting the impression that the LEDs die when the incandescent dies (at around 40-45 minutes). If this is true, it does not hold consistant with the catalogs claim, that the LEDs can last for many more hours after the incand. dies.
So what is the truth? Does the LED die at 45 minutes too, or does it keep burning for "many more hours" after that?
If it does or doesn't, will not really affect my purchase decision...the thought of having CONSTANT WHITE LIGHT for at least 35-40 minutes overides all it's shortcommings. But, if the LEDs do indeed stay on after then incandescent breathes it's last breath, then it would just be iceing on the cake. /ubbthreads/images/graemlins/grin.gif
