Eagletac D25c XM-L2 U2

Eyerelief · Oct 4, 2013

Hello All,
I have been a member for a couple months, read what you good folks have to offer often. This is my first post because I'm not smart enough to contribute intelligently, I still have much to learn. I do have a couple questions that I would appreciate some guidance on if convenient:

1) I just purchased the D25C. I had read that if a 4.2V LI-Ion battery was used it could be driven to 700 lumen output. I purchased the Eagletac Li-Ion 16340 RCR123A battery to go with it. I charged the battery using a Nitecore 4 slot charger that claims 4.2 volts output. After installing the battery I did not experience the two mode function, one being low, the other being 700 lumen out. Is this because I failed to get enough charge in the battery or because even though I purchased the original D25C, it came upgraded with the next gen LED? If the newer gen still has the 700 lumen function, what battery / charger combination should I be looking at for the higher output?

2) I have a 1980's vintage 6D cell Maglite that I am looking to modernize to LED. What would you folks recommend for an LED modification to make this light a long distance thrower. I have an Olight SR90 and don't expect the Maglite to throw further, but would like a similar beam pattern with as much throw as the old light will allow.

Thanks in advance.

I'm going from memory here but as far as the D25c goes, I believe you have the 2nd gen version with the XM-L2 and new driver first introduced in this light w/the 2013 Ti version. As such, it is now fully regulated and you'll now maintain high-medium-low with high toping at around 400/450 lumens or there about. I have two of the 2012 D25c's and those will indeed hit 700+ lumens with 3.7v Li-ions (*they're only at 4.2v hot off the charger...3.7v is the nominal resting voltage) That 700 lumens however, comes with the trade-off of losing medium altogether and getting very hot, almost too hot to use without risking emitter degradation or failure within 30sec to 90sec. IMO you're actually better off with the more fully developed driver of the 2013 version you now own. Sorry...can't offer anything re: the Mag mod.

I would suggest reading all of page 14 and page 15.

Hi guys, new flashlight guy. Bought two so far, cheap ultrafire 502b and the very nice and small edc Eagletac D25c Ti 2013 (with rcr dimmable). Here's my issue, in a direct comparison to the cheapo ultrafire 502b, which seems to put out a solid 500 lumens (based on readings on internet), my brand new d25c Ti is about the same or less WITH rcr123a EagleTac branded batteries. I don't have any cr123a yet to test but is it possible that the ET branded rcrs are not sending the Ti into directdrive? I bought the 2013 Ti version with the upgrade led (450 lumens before overdrive) because it has all output modes with RCRs but I am doubting that is throwing 750 lumens.

Eagletac's website is a mess, as they updated some of the 2013 XM-L2 information, but left in a bunch of 2012 information that is now incorrect.

Both the 2013 Titanium XML and the new 2013 black aluminum XML2 D25C models have the A950RC III driver that has dimmable Li-Ion support with regulated Low<Med<High levels, but the direct drive Turbo mode does not hit 770 lumens like the 2012 D25C does.

Thank you both. Looks like I was a little late getting on the 700 lumen light, but after reading, doesn't sound like I'm missing much. Still a very nice little light.

Thanks,

You might look at the D25A Clicky version of the light if you are not tied to the CR123 format. It's a bit longer but thiner (AA) and on a 14500 the XM-L2 version is about 750 LED lumens. On med and low it's current controlled but on high/turbo with a 14500 it's direct drive. It does get warm fast on high but is very impressive overall. My most carried EDC. The XML2 and XPG2 versions are 2013 and support three levels with the highest being direct drive with a 14500.

I have not heard of a D25A 750 lumen model with 14500. Is there a link with documentation and proof?

The claim is on Eagletacs web site - see quote extracted below from the D25A clicky product pages

"CREE XM-L2 U2 LED
141 ANSI lumen, Fair far projecting performance, excellent (relatively floody) beam profile

Offers up to 750 LED lumen when direct drive with 14500 li-ion battery."

While I have no measurements my D25A Clicky appears brighter than a few other lights I have that are speced between 500-600 ANSI lumens.

Exactly when and from whom did you buy your D25A XM-L2 U2 light?

Have you had a chance to read pages 14 & 15.

It appears Eagletac might have recently gone back to the original A400RC and A950RC drivers for the D25A and D25C model. They have removed any mention of "Dimmable Li-Ion Support" on their website, as far as I can see.

Got that particular light (Aluminum 2013 Eagletac D25A Clicky XM-L2-U2 Cool White) in early September 2013 through Amazon (from Lumen Tactical). The packaging had the older XM-L-U2 numbers on it and an "Updated 15% brighter" sticker with the XM-L2-U2 reference.

But I also have a late 2012 XM-L-U2 version and a 2013 XP-G2-R5 version and all feature "dimable 14500 support". That is you have low, med, high (not sure if turbo is any different than high). Each of these levels are somewhat higher than with non 14500's and you can't get the moonlight modes, just the three standard modes.

I can't imagine they went back to previous driver versions, but I guess anything is possible. I imagine its just not a "new" feature anymore so they omitted it on purpose or its just a pure omission with the site update. The link you provide looks like a discussion on a D25C which does not )or did not) use the same head or driver as the D25A.

Hope this helps

So as a newbie, I've read all (I think) appilicable posts and reviews for the Eagletac D25C Ti XM-L U2 which I have just purchased but have not recieved.

Looks like I can buy any one (but not limited to) of the following batteries:

Protected AW 16340 3.7V
Eagletac 3400 mAh 18650 cell
Eagletac RCR123

Question is which one and which charger? So many choices it's overwhelming. :faint:
