Seeing as they are probably up to 500 plus units sold, only 10-15 seem to have issues. Overall that’s not too bad a ratio. Like 3%.

When my mother had knee replacement surgery—They assured her only 1 in 100000 had infection problems—very low percentage—Low and Behold hers got a bone infection—-It really SUCKS when you are that percentile——- Facepalm Facepalm

Darn… hope she recovered OK. And your right….. it does suck when “you” are the percentile.

Saw the Tigers pull out another one…. good luck this coming week. Wink

Hopefully we will keep the ‘big head’ at bay & continue the course to #18. Wink

Yeah, I know…
……. It is waaayyyy to early to mention that, but I just couldn’t resist. Big Smile

I have a feeling Monday & Tuesday were long hard “days of learning” spent on Thomas Field, for several players in Tuscaloosa this week. Big Smile . Wink

I was told anything under 10% is considered acceptable. So right now the current lights can be fixed without much problem.

“They” must have got their zeros wrong. Officially it’s more like 1 in 100. I worked in radiology for a few years, and especially with ortho surgeons. Infection can occur up to around two years after the surgery too, but the percentage goes way down.

Can someone confirm my suspicion on the tint of my two lights for me? I ordered two NW but believe I received one CW. I guess I hadn’t compared them side by side until now and it’s pretty obvious to me but I’m just looking for some confirmation from the professionals. What say you?

Sorry for the crappy pics. I don’t own a professional camera.

Geez, thanks Robert… one more thing to worry about. Would a ti plate with 6 screws on my spine qualify for that or is more related to joint replacement issues?

I am interested in what Robert says because it sounds like he knows, but what from what I have been told; that applies mainly to joint.

For what the pictures show, I do not see a big difference in colour temperature, they may well both be neutral white, but there is certainly a tint difference. Tints within one batch of leds can differ a lot if not a tight tint bin is ordered by the flashlight manufacturer (ususally that is not the case so I’m not surprised).

I don’t think they specify the exact led bin. The more yellow one could be a 3B or 3C and the pinker one a 3A or 3D. The pinker one might be under the BBL and the yellow above it. Or maybe they are both a 3A or 3D just at opposite ends of the scale. That would be my guess.

hm it looks like 2 different tints in my opinion… i think someone else also got 2 different looking colors so who knows… send pics to Neal and let him decide if they sent wrong or not?

If that are 2 of same then thats not acceptable to me when u clearly can tell them apart.

@mortuus: both tints seem to fall in the category “neutral” so you may be demanding more than what is promised.

For us flashaholics there are a few sellers who deliver single Cree tint bins, but that is the exception, a luxury that costs extra, it is not how the leds are normally sold by Cree. Normally it is a grab bag of tint bins around a specified colour temperature, containing 4 or more tint bins. So receiving tints this far apart is a normal thing to happen.

Looks like those two lights fall in the Neutral White normal range, like Jason said probably a 3D and a 3B, but a Cool White would normally show much brighter with a cool blue-white look to it, not the slight yellow or brown color of that cooler one. The one sure looks like 3D though.

I used to order from Mouser and they would send mixed lots of stuff like this, quit buying emitters from them for the most part for this very reason.

That’s truly horrifying. Looks like it’s the very last torch manufactured by Lumintop I bought Sad

To me if this is acceptable ratio then it was my last Lumintop light also if thats the kind of quality the offer then no thanks, feels like the replacement head wont come either, been 3 weeks now almost but i will wait a little more, then i will just pack the light in its box and it will collect dust i guess and 40$ wasted on crap…

This could be all China flashlight manufacturers, not just Lumintop. It’s all about keeping production cost as low as possible. You save more money than loose it by fixing a small percentage as opposed to doing lots of quality control checks and getting it right the first time.

As far as the GT MINI and Lumintop is concerned, they are only at 3% which is quite good. They are not loosing much money fixing 15 lights out of 500+. As long as they fix it, I’m okay with it. There are other companies that don’t like fixing things at all.

Keep in mind that even if you do spend extra money doing more quality control checks that there are still always going to be a certain percentage of lights with problems. This is the same for Acebeam, Olight, Nitecore, etc…

Where did you get your numbers (3%)? I think that if you see a lot of complaints here, there are a lot more we don’t know of.

Don’t see complaints in this amount for instance with the D1s.

Seems to me lumintop does has quite some quality issues with this light.

15 ÷ 500 = 3%

I don’t think BLF has ever done a group buy on the D1S lights. So I would imagine that if there were any complaints about it, the people would be complaining directly to International Outdoor Sports Store rather than to this forum. Maybe some people would mention it in a review thread? I don’t know.

For sure the defects rates vary with every model of light regardless of the brand. Like the Haikelite MT09R. Pretty much all of them had problems. Even the BLF Q8 had issues with the switch lights in the first batches. Some light models might be 0.5%, some 3%, some 20%, some 100%.

In my opinion, it’s not so much what the percentage of bad units is, it’s how the company responds to the issues. Like the Fireflies ROT66. All the xpl-hi versions had crushed emitters. They took care of the problem quickly. This can be an inconvenience to customers, but at least it was taken care of.

Other companies like Imalent may or may not fix the problem. They seem reluctant to fix anything. Or else they will charge you for a new head, etc…

Right now Lumintop seems really good about fixing their products. It took them awhile to fix some of the GT issues, but we are currently at 7 out of 1500 needing an issue taken care of, most of which is related to missing or damaged shipments which you can’t even say is a defect. If we count all 7, this is 0.5%. We hope to get it to 0% soon.

Bottom line, I don’t see how you can really bad mouth Lumintop when there are other companies that are much much worse.

Not badmouthing, I have some lumintops that I am really happy with. And I am sure Lumintop will make things right. Just getting the impression that there are some QC problems with this model, that people should take into account before purchase.

Probably it’s just me being grumpy, but having to return a light or waiting for replacement parts just spoils a lot of the fun for me. Trying to avoid it even since the S41 decapitated led versions.

I also thought there might be a big defect once we heard leds were turning blue and some falling off the mcpcb, plus some switches where acting funny. I told M4D M4X there could be a big issue back on Aug 27, but he assured me it’s just normal stuff and a small percentage. It seems he’s right.

BTW, achieving a less than 10% defect rate was over a 1 year period, not just when it comes out. Keep that in mind.

I believe that 10% is shedloads even after a year.. I bought a bit of electronics in my life and the failure rate is nowere close 1/10 and we have to remember that flashlights are relatively simple devices.

Anyway, did anyone try changing the switch themselves? I never disassembled any flashlight apart from Solarforce L2P and don’t want to make the situation even worse, so excuse me basic questions.
Basically I got to the LED after removing bezel, lens and reflector, do I need to unsolder wires from the mpcb and push the driver out? Is that it?

I’m still waiting for banggood to come up with a solution. I did actually email Lumintop service themeselves but they don’t seem to care enough to reply (another reason not to bother with them).

That is it. The switch is soldered to the driver so you have to swap the driver out.

I think they will send you a new head as people can’t be expected to completely disassemble a flashlight and solder stuff.

Did anyone hear anything from Lumintop service though?
Or are you talking about people who bought directly from Neals? I unfortunately ordered mine from BG.

FWIW, Hank runs the store called Intl-Outdoor, there is no Sports at the end of it.

This is the home of the now legendary Noctigon MCPCB emitter board with Direct Thermal Path. And the Noctigon Meteor M43. Wink

I guess it was Store instead of Sports. I think of it as IOS as in RampingIOS. I guess he dropped the last part of the name. It’s confusing for me. Lol
