Re: No really, what IS taking Arc so long?
Same here.
Interchangable heads of varying runtimes & power would be sweet!
I bought & like the Arc-P because it was small enough to fit on a key chain without breaking, having a decent runtime to get through most of a shift or night continuously on 1 battery, but still be bright enough to be useful. There were already lights out there much brighter & whiter with significant shorter runtimes, or require bigger, or more expensive batteries (or more batteries). There are also dimmer lights out there that will run 11 or 12 hours on a single cell, or 70-100 hours on a low setting.
I'm not a flashaholic. I need decent lights a lot (at least daily) to do some of my work. I bought the ARC-P because it was a practical, economical, useful, & durable light... not because it was cool or particularly fancy. It gets the job done well.
I would not give up it's place on my key chain to something else with less runtime, or takes weird expensive batteries even if it was brighter.
If they can make it brighter or whiter without sacrificing efficiency or price, that would be cool.
To make a brighter power hog, perhaps an AA version would do, so it still would have the power to last most of a work shift or most of the night if it had to.
If Arc-P didn't exist, I'd probably have a practical, small Shorelite Vx1 or Vx2 on my key chain for the long run time. If it broke, they're cheap... I have a few of 'em.
I won't buy any light that doesn't take common inexpensive cells, & won't keep lit for most of a night or shift.
I bought the Arc-P for 2 co-workers for Christmas & they love them. They're still on their original cells!
From 1 - fully & freshly charged 900mah rechargeable, I get about 6 hours of bright usable light, a 7th hour of fair dimmer light, & an 8th hour of very dim light to get one through a dark room or staircase if I really had to.
As LEDs get brighter & more advanced, I see LED flashlight runtimes become shorter... in some cases as short or shorter than their incandescent ancestors, losing the advantage LEDs originally had over them. If I have to pack large batteries, extra ones, an extension cord or charger, it kinda defeats the advantages of an LED light.

Re: No really, what IS taking Arc so long?
Is the Nichia CS really anything like 90 lumens/watt? That's up there with the latest and best Crees and the CS is around 2 years old now. I thought it was more like 50/watt and the old (BS?) was maybe half that.
Now that the new LS is complete can we talk about this update again? And how about an Arc AA revival? For the AAA update I'd simply replace the led with a neutral colored one, and make incremental improvements to the electronics. For the AA, I'd use a Luxeon Rebel but keep it set at the old power level, 50-60 ma.
