Well, Thrunite sure has exhibited an apathetic attitude towards the issues expounded upon in the beginning and has now seemingly addressed them albeit to a “senior” member like yourself JohnnyMac. I find that somewhat disturbing to say the least. Having to “drag out” a response from a business is a sign of less than stellar business practice IMO.
I’ve got mine working alright but still experience an occasional misfire due to the SLOPPY threading/contact issue. I think they should send all of us a new light and re-laser them too.
ETA: Or better yet like JM mentions…remove the pill from re-placement Saber and put it in existing lasered BLF head.
My BLF light still misfires and in high mode will sometimes flicker even when the head is snugged down and all contacts (incl. battery) just cleaned. The contact problems are worse than my T10, as that light misfires but once solidly “on” won’t then start to flicker when laid down on a table or moved around. I have received the same email regarding replacement, but no follow-up with shipping notification, no info about paying for shipping for the requested return to Illumination Supply, etc.
Why doesn’t Thrunite step up to the plate right here on Forum?
Seems like they are just ducking and hoping the problem will go away.
They know BLF’ers are pissed about these skeletons from their closet.
I just spoke with David a few minutes ago and he said that Thrunite will be replacing the defective BLF Sabers with new lights. If you haven't done so yet, or have already sent an email to their sales department, send an email to either service@thrunite.com or service@thrunite-store.com. I sent the email to both. He told me that they will ship out the replacements ASAP.
Sorry to hear about the problems with some(how many?) of these lights. I have to say after using mine daily since I received it that it is a very nice light. The threads are tight and smooth, the fit of the pill is much better than my Mini 01, the knurling and anodizing are flawless and the beam is narrow with useable spill. The only improvement I would make is a more evenly spaced medium and I may swap in an XP-G2 R5 3D and even that will be simple due to how the emitter is installed.
….but execution and/or QC undermined that. It’s interesting that several people have posted about having no trouble at all with their BLF Saber. Makes me wonder if the “BLF” printing went on lights from different batches.
I’ve gone over mine completely twice now: cleaned all contacts, made sure the pil is tight (it arrived loose), removed the tail spring and cleaned all contact points on spring and tube, tried different batteries, etc. It’s much better now, but I will still sometimes snug it down in “high” mode and the light will flicker or run dim. It’s hard to imagine that this is just a contact problem. And as I noted above, the head thread tolerances mean that the “misfires” of the original T10 are repeated here, which is a pain if you’ve turned the light off on “low” so you can turn it on again on “low” to check on your sleeping children and it skips to “medium”, which is very bright in a darkened room.
What a contrast to Rey’s “Bonny” that has been in my pocket for the past couple of days, working just fine (except for the faulty protection circuit on the batteries - but that’s not a reflection of the light’s quality).
I still think it’s the bottom contact spring that’s causing most of the issues. Since I bent the spring on my saber there have been no issues. I took a few pictures to try and show the problem.
Here’s the way I bent the end of the spring. Sorry for the blurry picture.
Here’s the bottom of the battery tube. I don’t know if you can see it here (kinda hard to take a picture down the tube) but there is a small step near the base where i think the spring was sitting and not making contact with the bare aluminum.
I have got my replacement today.
It works, the threads are clean, no sand, no lube but it is easy to operate and switches on every time without even thinking of a flicker.
The head has a BLF logo, the structure is a bit different on this one. The tail has a even sharper edge as the defective one but I can live with that.
I just have it for some hour but I have twisted it a million times and not even one problem orcurred. :bigsmile:
Reckon I must have been lucky as mine seemed ok straight from the off.
Beam is pretty good, rather cool, but not too much. Led is well centred and it seems to work as you’d expect.
That said I have mixed feelings on this torch. It doesn’t tailstand very well at all due to massive recesses in the tail. It has some really sharp edges on these tail recesses too.
The knurling is massively over aggressive and it feels like you are holding a file and makes your fingers/hands sore to hold and use the torch.
It has the nosiest threads I’ve ever heard on anything (even after lubing them). I wouldn’t say they are rough, but compared to my Tank007 EO9 which is silent and smooth in operation, this Thrunite makes one hell of a racket.
You also have to unscrew the head a long way to prevent the light flashing on, there seems to be a fair amount of play and slack in the threads that allows you to push the head down and activate the light. If you don’t unwind it far enough it’ll flash on and off in your pocket and of course lose your last mode memory setting to whatever it last flashed on with.
-horrible sharp edges on tail
-file like knurling that litterally sands you hands during use
-very noisy threads
-unwillingness to tail stand
-have to unscrew the head a long way to prevent accidental activation
I accidentally shorted the circuit on mine when taking tailcap measurements. I asked Thrunite if they could send me a new driver. They said if I sent if back they could replace the whole light for me, but I explained that I had swapped the emitter to Nichia 219 and re-wired the old circuit to direct drive and that I really only wanted a new circuit.
They just sent a whole new replacement and told me to keep the old one. Top service in my opinion.
I have interchanged the parts and compared them, the new one has a slightly cooler tint. The old one with new tail, makes no difference still doesn’t work proper, but it can’t be switched on with pushing the parts together like the old one. So I guess the thread on the tail is a bit different but I can’t see difference with bare eye.
I like the machining of the old one more( new one is rougher perhaps they used a bit worn out cnc drills)but the switch on mechanism on the new one works every time(for a twisty it would even be ok if it sometimes doesn’t work).
It feels like if the old one needs to be screwed further in to light up and that it then often makes no real contact or so…I haven’t unscrewed the old pill yet as it was really tight as I tried it and after that I threw it angry in my parts box…I will try that again as I am really curious what the issue is.
I just took a small walk outside with a TF flame( nitecore is too fat) and wow that little light is way more than useful, it pulls 1.7A!!!. It is almost as bright as my mini01. I am so happy that I ordered one.
Hope they follow through!
