Very nice, like the modes. I had only one problem - I have some vapex instants (no laughing at the back) and they don’t fit the tube, eneloops and duraloops do.
Duracell and Energiser AA fit too.
On the Flats mine has Thrunite T10 on one side and Saber 1A on the other
So overall I’m happy, as has been said before nice smooth threads and very nice modes
EDIT : Looks like the spare o rings are for the Ti AAA though
Thanks. Was worried mine wasn’t normal. Maybe the noise is used to chase small little bugs away from the firefly light?
Mine arrived today, and since I came home for lunch I took a few minutes to check it out.
First, there were major contact problems, even after an alcohol cleaning: light wouldn’t fire, or would flicker, or go on and off by itself after tightening. There was more manufacturing grease and sloppy, thin thread grease than on my original T10, and the threads were rougher. Another cleaning and 760G application and no better, I wondered about the contact spring and reached in with a pair of needle-nose pliers and rotated it half a turn. That seems to have done the trick, as it’s running correctly now.
The beam is like my original XPG T10, but a little bluer (and just barely brighter). Although it’s rated at 169L it’s noticeably less bright than my ET D25A, rated at 121L (ANSI), and still less bright after the D25A drops down to around 100 ANSI lumens after 3 minutes (of course, maybe EagleTac underestimates their output, as has been suggested elsewhere). And the CW tint of my D25A is much nicer. Moon mode is nice. I’ll run a few duraloops through it and see how it looks after a little burn-in.
All in all, not a bad little light, but considering what else is out there it’s far from mind-blowing. The coolest thing about it is that it has “BLF” on the head.
EDIT: My D25A is an XPG2 R5
Not good! Not good at all. 
WTH has happened to Thrunite?? These quality control issues are popping up way too much on this light. Starting to look like they crapped out a bunch of seconds and pawned them off on us by engraving “BLF” on them. Poor LEDs, weak drivers, poor assembly, inferior machining, using battery tubes from a different model…simply inexcusable! Starting to not look forward to getting mine. 
I don’t want to be a downer. At this point I’m used to a clean-up and relube with Nyogel 760g on any new light, even those costing north of $100 (it blows away every factory lube I’ve experienced, and it’s conductive). The light is now burning fine (I grabbed it and a case of NiMHs to keep it running the rest of the day). I wish the tint was different and the output a bigger step up from the old T10 I have, but I knew the XPG2 would only give about 15% more than the XPG. I do wish the threads weren’t rough though, as I like the smooth one-handed operation of my old T10. I’ll see how I feel after a week of use.
Should probably be a $12 light, not $20.
I hear ya JM. I hope Thrunite is listening. Could be end of road for me and Thrunite. :~
Mine will be here in couple hours.
I was under the impression that the xpg2 was a clean neutral white and noticeably brighter than xpg.
ran home on lunch found my 2 sabers in the mailbox. i unscrewed the threads (felt like they were about as smooth as sand paper) and put a battery in the first one and nothing. can’t even get it to turn on. I put a battery in my second and it wouldn’t turn on either. pissed, I smacked the light on my hand and it finally lit up. I put an eneloop in it (which barely fit) and its shorting out and flickering.
what happened?? and I don’t know any lights I can compare the tint to besides the fenix e01 if that says anything. except the saber’s beam is a lot more ringy than my e01s have ever been :~ LEDs are both off center in mine (which wouldn’t bother me so much if they would actually light up!). so glad I bought two of these…my group buy archer comes tomorrow I hope it’s not going to be like this…these were my first and last ever purchases from thrunite. I hope they will at least fix or replace these lights
lol i didn’t expect much in the first place besides them lighting up. that would have been nice. i don’t know what to do with these…the pill/drivers are all the way tightened in the head. i tried tightening the contact spring in the end with no luck (although i’m not sure how that would help…it appears to be making contact regardless?). I guess my next step is to email thrunite. i’m going to try cleaning up and properly lubing the threads and hopefully that will fix something
This is not sounding good. I hope Thrunite are willing to sort out these issues else there might be quite a number of PayPal claims.
I guess I’m a lucky person. I’ve been playing all day long with mine and works great.
So sorry for those who have problems. I have a t10 and this Sarber 1A and both seem great flashlights.
(are good flashlights in a mid range 15-20 $, not more expensive)
Isn’t the step-down from turbo on the D series supposed to be around 20%? That’s certainly what it looks like to me……
I’m surprised at the small but noticeable differences in build quality between this BLF Saber and my older (2012) T10. Everything on the older light just seems to fit a little better. I wonder if they are from the same factory? And why in the name of God didn’t they make the tailstanding platform a little better?! (Well, I knew they hadn’t, but still…. 
)
Interesting comparison.
My BLF Saber works fine. I can’t See anything wrong with it.
Well, I guess I’m lucky with the BLF Saber. Worked perfectly out of the box. LED centered perfectly also.
Compared to my T10, the threads on the BLF version are rougher but acceptable.
Also, xpg2 tint is a tad warmer (pinker) than the xpg T10 and as a result the colors pop with the xpg2
Othere than that, no difference really between the two to warrant one besting the other. However, I do prefer the slightly warmer tint of the Saber.
Oh, there is no whine in firefly mode on the BLF Saber….there Is on the T10…never knew the whine existed til I read about it in this thread. And you have to stick it in your ear to even hear it… 
LOL….look at Johnny Mac’s Avatar…he does it all the time… :party:
ok so after playing around with these for a while they are working fine. I had to clean all of the threads out, lube it up, and play around with the spring a bit to make sure it was solid and they seem to be working fine now. as long as these work I am completely happy. my main complaint is the off-center led’s on both of mine, but this doesn’t make a huge difference either way. as long as they continue to work i will be happy with them. I think they were just rushed and threw them together in the factory…hopefully they will read some reviews/complaints and take the extra few minutes to clean up their products next time before sending them out.
i have an eagletac d25c xm-l u2, so it can’t be directly compared, but the d25c isn’t much brighter than my sabers. i also have 2 foursevens mini ml xp-g2’s, and they are pretty close in brightness. the foursevens have a tighter hotspot are a bit brighter, but they are also using cr123’s instead of eneloops so that isn’t a big surprise. i will say that what i used to think were nasty blue tints on my foursevens look completely nw now when put next to my sabers. (to be fair, the foursevens and eagletac lights are over double the price of the tn saber as well…so even the fact that they’re close is pretty impressive)
overall, for what it is and what i paid i am pretty happy. i was pissed when i first opened up 2 broken lights, but after a little tlc they turned out decent.
I’ll be checking the beams tonight of the xpg2 vs xpg when it gets dark.
I saw a comparo of the beam here a while back…in that comparo the xpg2 did best the xpg.
Waiting for darkness…… 
Before Step-down with full eneloop, for my eyes a little brighter D25A XP-G2 (the difference luxmeter 270 lux at 1 meter). With eneloop emptier (use half), the difference increases to my eyes (for luxmeter the difference is 375 Lux). The D25A is brighter (also costs twice) 8)
0:) I agree with you, but others also been disappointed to me, lie about runtimes, is lying on lux … even some people say that man has landed on the moon …… :bigsmile:
