After a long wait I finally received my 2 GT’s. Almost 180 days after I paid the whole amount, almost 120 days after shipment.
I was 269 on the interest list, 185 on the payment list, I am one of the last people who receive the lights. I know that LT was not looking at the list order when doing shipments but I received my 2 lights almost 4 months after shipment. This would surely take even longer if it wasn’t for my interventions which were a humiliating task for me especially that a part of the GT Team was on the LT side instead of keeping the side of the people who ordered. Some were trying to imply to me (and not only to me) that the lost/damaged packages are my fault or the local post office fault, some of the packages arrived in their destination in a horrible state. Others asserted that the lost and damaged packages are less than 1% of all the purchases so everything is in order according to them. From the GT Team only Texas Ace has expressed understanding and was helpful for which I am very grateful. The way LT has dealt with people who got their packages lost or damaged was condescending to say the least. Problems which should have had priority in resolving were put off and taken care of as last.

Now a few words about what has been delivered vs. what has been agreed on with the GT Team. Maybe some people from the 4th round do not remember or are not aware what has been initially agreed on but I’ve been following the GT from the very beginning so let me refresh everyone’s memory:
- Packaging is different and a lot worse than what was shown in Neal’s video where the packages were drop tested for damage.
- Instead of 2 boxes, first for protection and the second with the GT light, I received just the main box taped with packing tape and an address sticker.
- The reflector is inferior quality than in the V1 prototype, you can clearly see the OP layer.
- Both of the GT’s I received have badly centered emitters.

To wrap up, this was my first and last purchase from Lumintop.
Not only do they make problems with damaged/lost goods but also deliver inferior quality goods from what has been agreed on.

Packaging & 1 box instead of 2 is no big deal as long as the GT got to you undamaged.
My last one had only one box also. No big deal, a non-issue.

Pictures of your inferior reflectors please…. good ones.

After reading the above (now deleted Alamo) editorial comments…. I do indeed see how hilarious it is. Thumbs Up . Wink

Frankly, I was offended by Alamo’s response to me trying to help him out. I don’t want to help people who act like that, calling me names and being insulting. We try to keep BLF a very friendly place for everyone.

Once I saw he quoted my post with Neal’s contact link I decided to erase my post as it was no longer needed.

Then his bizaare sounding response to ToyKeeper in post #1963 I knew I made the right decision.

I don’t know why I came back a day later to try and figure out his order. I probably shouldn’t have.

After his most recent post (#1986) he’s still calling me names as well as making accusations now. I wash my hands of him.

I don’t think he’s insulted Texas_Ace, yet. Maybe he can help him with any future questions.

I’m not a good judge of reflector finish, but if you want to try and center the reflector you would need to loosen the upper head from the light engine. The threaded section right above the switch. When you loosen it there you can wiggle the reflector some to get it centered, then tighten it back up. If you completely unthreaded and separate the two parts you need to make sure to put the black centering ring on the emitter first and then thread the head down onto it.

But I hope that Lumintop is working on a next version of the centering piece, it is not that hard to make one that actually does center the led, and if there is one flashlight that demands a well-centered led it is the GT. And trial and error DIY wiggling a reflector is not what you hope for in a high performance flashlight (I had to do that too often already in my budget cheapies).

I presume I should polish the reflector myself too?
I know how to center an emitter, this is irrelevant though. This should have been done at Lumintop not in the buyers garage.
95% of the splendor of this flashlight is a reflector and just this most important thing is screw up.

Thank’s djozz I too have cheaper flashlights with better quality of reflector.

No, don’t try to polish it or even touch it. The shiny finish is ultra thin and it’s very easy to damage it.

There has not been much news to add to post #1. I did a small update:

Quote:
All of the missing and current orders should have shipped the week of May 23rd. So they should now be on the way. A couple of the replacement lights have already shown up. If you are needing a replacement part due to a defect or damaged shipping please contact Neal to work out the details. His contact details are down below in post #30.

Okay.

It beats me how Lumintop can’t get it centered just right. The design of the black centering ring is pretty much fool proof. Maybe the screws are not the best thing to center it on. Maybe their tolerances are not tight enough. Maybe they switched to screws with a smaller head so now the centering ring can wiggle.

I think the reason they switched to using the screws to center it was because the emitter corner would sometimes gouge the black plastic and create a black plastic shaving which could then fall on top of the emitter and smoke up the reflector.

All they really need to do is cut the center hole with a taper on the bottom so it self centers. Done.

Thanks for that video Jason. I didn’t know what you meant by the light engine. I didn’t know there were threads there. Very helpful.

Not a flashlight guru, but like them just the same.

Ok, I don’t have time to address each post but first off lets all take a step back. The GB is over now, lets not start up drama after the fact.

I will freely admit that mistakes were made in the GB, particularly early on.

Lumintop’s choice in how to ship out and handle orders was not what anyone on here wanted but trying to change it was just not easy to do and most of it did make some level of sense from a business standpoint. It was a case of pick our battles.

Retrospect is 20/20. Would I have done things differently given the chance? Yep. Heck at many points getting involved at all seemed like my biggest mistake. lol

I like to think we corrected most of the issues by the last 2 batches, they went off very smoothly IMHO. These were also how the entire GB was supposed to go. The reflector delays threw a massive curve ball in the whole process no one saw coming.

I apologize to all those that got lost in the cracks throughout this GB. That is something I never wanted to happen.

When this was started the entire GB was only supposed to take ~1 month start to finish. So in that time frame it was understandable to take care of the big issues before dealing with the small ones.

Had we known it would be a 6 month long ordeal, things would of been handled very differently.

The issue with the centering rings was that the first style would melt after extended use, which I did see evidence of in my prototype light. This could smoke up the reflector and cause lots of issues.

I have told them to more to a white centering ring a few times but never really got an answer about it.

Smaller flashlights have centering rings that fit snugly around the led and are centered by the led itself. I can understand that with a reflector this heavy you don’t want that in fear of shearing off the led when the flashlight is bumped against something. Their solution is not bad: position the two screwholes for the ledboard very precisely and use the screw heads for precision-positioning of the centerpiece. But those holes must be indeed positioned precise, the screws must have precise heads (preferrably not round but with a straight edge), and the screws must be screwed in with some care so that they go in straight without cross-threading. One or the other was off in part of the GT’s.

Good informative video Jason, I noticed that you haven’t cleaned the soldering flux off the contact wires, you might want to do that before running your light at full power for long periods of time to prevent it from smoking the reflector.

This is how mine was before I cleaned it with alcohol and a Q-tip being careful not to leave any strands of cotton afterwards.

I don’t have any liquid under my centering ring. Are you talking about the flux residue around the solder points? That is dried up and hard. It should not cause any problems.

Good video Jason! Thumbs Up

Excellent info & pics AlexGT!! I remember when you first posted this. Your pics convinced me to clean all of mine before heating them up real good. None of mine were as bad as yours appeared to be… but better safe than sorry.
Thank you!!! Thumbs Up . Beer

Are you saying the mcpcb can heat up enough to liquify the hardened flux residue?

Jason…. Look closely at AlexGT’s pictures. Look at all the liquid crap that was under & on the bottom of his black spacer. Look at what is on his fingertips also.
I am pretty sure that mainly is what he is referring to.

He said I need to clean my light, but I never had excess flux under my centering ring. Nor is there any visable in my video. So I’m just confused why he would tell me that.

What I meant is that I think the dry solder flux might liquefy by heat if you use the light on turbo for longer periods of time creating a smoke hazard for the reflector, I cleaned mine up using alcohol, not hard to do…

Now I understand. I have never heard of this before. I thought once it dried and hardened/crystallized that it was no longer capable of becoming liquid again. I can remove it, no problem.
