So they almost doubled the output!!! :) Can't wait to do my side by side runtime tests. I hope the increase in output is solely the result of a more efficient emitter and not at the cost of efficiency. Heading out to purchase some USA made Duracell AAA's today. I have a pile of Energizer lithiums at home, so I'll run old and new on both side by side.

Absolutely count me in as very much looking forward to your findings!
 
Looking at the old runtime graph Fenix had for the E01, it does look to reach 10% at around 16-17 hours, so I'm willing to bet that all that has changed is the LED and theuse of ANSI specs.

Tell ya what - while scout is testing the run time, I'll pop mine in my sphere and give out the front lumen ratings for both "old" and "new" versions. USPS says mine will be here Saturday 1/31. Let's see - bullet proof, long run time, output increased, price reduced? What's not to like? Sure, they aren't the most technologically advanced lights out there but proven reliability trumps bling every day (IMHO).
 
Anyone ever thought of asking Mythbusters test the bomb-proofness everybody keep claiming? :)
 
Jamie seems to be ignorant of the basic engineering aspects of flashlights.

I have an aspheric lens.

This is the best shot I could get.

Yep, guess the other shot looked like a parallax issue. The wire is slightly off for the larger substrate but straight down the middle. With the tint through the aspheric lens, hmm, still can't tell if it is a 510 or 570 but now thinking 510 looking back at the white wall beam pictures. There is more of a hot spot. The 570 is quite a wide beam.

I didn't get a very good photo with the aspherical lens so I don't think it will help much in making a determination.
 
Just to correct my earlier speculations about a few things,

with the drive current, I forgot that our fellow CPFer Chimo showed that the driver is constant voltage at 3.2V. This results in around 24mA for the old E01 and 48mA if this was the 570GS. That would result in the 13 lumen spec.

The other thing, I just put a 510GS in a battery junction freebie keychain light and oh was it blue. So blue. This is not a 510GS, so I am almost certain that this has to be a 570GS.
 
So I think this is the third iteration of the E01, all using the Nichia GS starting off with the 500, then 510 and now 570.

A couple of years ago, some users had mentioned that the packaging had changed and it said 13 lumens rather than 10. Didn't occur to me that they updated the LED back then to the 510 and now we have finally have a version with the 570. It also makes sense now why Vinh's warm white mod looks brighter than my stock, as that probably had a 510 warm white.

Only problem now is to let all the stocks of the old E01's sell out so I can get one with these latest LED's. Or hope Fenix finally makes an AA version of this. Would displace my Gerber Infinity Ultra if they did.

I always feared that Jamie is a bit of an *ss. They try to dress him up as the mysterious walrus-man, but in reality I think he's just an a**.

ON TOPIC:
Since when is the latest update? I've got a Jan 2014 E01, at close range the beam is ok, but from a few feet it is definitely purple.

I got mine from Fenixgear for less than $10 shipped with the coupon code "WORK". I would like to see an AA version myself, it would go well with my Gerber Recon which can run on an AA or AAA.

I don't know when they updated them, I don't think Fenix made any announcement of an upgrade, they have recently changed the specs though.
 
Flashaholics have been hoping for a AA version of the E01 for years. The closest I've found is an Arc P with a AA body, or, even better, I have a Peak Kilimanjaro SS with a single led.

I ordered a new E01 in olive, can't wait...into the B.O.B.

It may be easy to tell which iteration is which by the packaging. When they updated the lumen output for the 2nd iteration, it was still advertised as having that 21 hour runtime IIRC.
