Ok - update on my test. At 25 hours the output measures at .6 lumen. Below is a photo of an HDS Tactical Rotary XPG2 on the lowest setting (.02 lumen) on the left with the E01 on the right.

I'm going to get it go and see if it'll make the 37 hours that Cerealand's made...

 
Lookin' good, Dan! I just dug out an Arc AAA, a Peak Matterhorn, a NOS E01 from four years ago, and a never carried Vihn modded one from his early days on the Marketplace. I'll start a seperate thread after opening my new ones to torture test tomorrow afternoon. Charging a camera battery, and getting out some Lithium primaries since you and Cerealand have the stock battery and Duracell alkaline runtime tests covered. :) I'm excited to be thrashing on one of these again! Four years later, hoping they are just as bombproof. We've even got snow coming in tonight and tomorrow so I can shovel with one again!!! :twothumbs
 
Update - now 30 hours - .45 lumen. Will still provide enough light to navigate around a dark room. Any of you ultra low lovers know that half a lumen is almost 'blinding' in darkness.

Just received mine. Brighter, but still a purplish hot spot. those of you who got a nice cream color won the tint lotto.

Don't forget, there are two 13 lumen Nichia GS out there. It could be that you got a 510GS and other people have got a 570GS.

Maybe some are whiter than others, mine has some purple tint in the hotspot but not near as bad as older versions.

That sounds more like the 570GS. I have some 570GS that I swapped into a 3 LED light and that description fits perfectly. The 510GS is like the old 500GS in the original E01 but more efficient so will be brighter. At some point, the 510GS version came out and only a few people queried it due to the different packaging and new rating but no-one had made that connection.

Mine came today. All in the 'new' blister pack as Grijon mentions. All have the ugly purple hot spot with blue and white out near the edge of the beam. New one measured 14 lumen in my sphere - one of my old ones measured 8 lumen. Definitely time for some steel wool treatment!

That definitely sound like the 510 or 570 being driven at 3.2V, which means around 50mA over the LED. If the driver is the same, then 3.2V on the old one is around 25mA over the LED and 8 lumen is about right. Where are all our white led testers that used to frequent this forum?

Hmm, if the tint is still purple I'll just stick with my good old 2008 model. Brighter purple with less runtime doesn't do anything for me. :shrug:

Runtime, if it is just an LED swap, will be pretty much the same. The circuit is constant voltage so the 80-120mA draw from the battery results in 50mA through the LED on the new version where as the old E01 means less current through the LED for relatively the same drain.

On March 1st, 2014, I received (from Amazon)
a Blue Fenix E01, which was now carrying a 13 Lumen Rating on the box !

I would guess you have a 510GS in your version.
Burgess said:
Tested it, against my Previous E01 models,
and this new model was more than 1 f/stop Brighter !
( on my Sekonic L-308 DC handheld meter )

Still had that charming blueish tint, however !

Definitely think you have the 510GS. I think I need to buy some more 570GS and show the comparison. Only problem for me was that the 570GS was quite floody for what I wanted but there may be some more focused ones now.

Burgess said:
I would REALLY like to know:

Has the electronics circuit changed ? ? ?
Click to expand...

Can't help you there but I don't think it has changed. With all the observations on here, I would say it was just an upgraded emitter.

3.2V? I'm confused....please explain? 3.2 with an AA?

With an AAA even ... but as Yamabushi said, boost circuit. The E01 is unique in that is uses constant voltage, where as other lights you may know will use constant current. Most cheap lights just use a simple voltage boost so the output will not be as constant as the E01 (down to 1V). After 1V is what they used to call the moonlight mode.

Good deal - thanks for the explanation. Oh, I meant AAA. Typing on iPhone is often an exercise in errors for me!
 
Ok - another update. 32 hours an 15 minutes and we are holding at .45 lumen. Plenty to navigate the dark house tonight.

Another photo comparing to the HDS on .02 lumen low...



Completely dark room - no flash - iPhone 6 camera



I'm thinking it'll still be producing a small amount of light in the morning. We'll see. If so, that'll be getting close to 40 hours.

I've read about your previous torture numerous times and I am very excited about what this thread already has and also where it's going.
Let The Torture Begin!!

Mine should be here tomorrow also. I might do some runtime tests of my own. In a previous E01 thread, I did some tests with older models and my runtimes were nowhere near as good as others. I'm curious to see if I do better with these new ones.

How long did it run before going into the moon mode?

I honestly don't remember for sure, but it seems that it was around 17 hours? It has been a slow but steady drop since then

run4jc,

Did you use the steel wool mod on your E01?
Click to expand...

Yes indeed. Comparison photos posted HERE

This morning with 40 hours and 45 minutes of run time, 'the little E01 that could' is still producing useful light. IIRC, scout24's went 60 hours or so? We may see that with this one...

I cheated and took out the battery just long enough to test the voltage...read .65 and was showing signs of climbing ever so slightly. .22 lumen in my sphere. And again, compared to the .02 on one of my HDS lights. As a reminder, this is one of the "new" models with the slightly higher output - arrived in a blister pack rather than a box.



Last night


This morning
 
Last year in April I bought an E01, having sold my first one a few months before that. Now I'm wondering which version I actually have. Of course, I don't keep my box our manual.I've just contacted the retailer to ask if they have any idea what version they had almost a year ago, lol.
 
Ok, seems like I had the old one, lol. So I ordered the new one :D It'll be here tomorrow, hopefully.
