[PART 1] Official BLF GT Group Buy thread. Group buy officially closed! Lights shipping.

The die is centered on the holes, so if you use screws to mount it then it doesn’t matter that the board is offset.
Or you could simply read the datasheet and do some measurements and use math to center the LED properly on the shelf.

So it seems like a Neal’s crush or a just a sensitive personal without empathy……

I got some “rude” too when I posted the print of the sarcastic reply of this guy I think I’m the wrong here and I did should thanks neal for his outstanding work here….

I understand that,I’m very ungrateful personal and another one was G_sintornillos how he can expected a better reply than “its expensive to send to Uruguay, so it sent to usa”……

For those who are getting problems with the shipping I will share my experience: both paypal and credit card have 180 days protection and after that you cannot place a dispute or charge back anyway, so keep an eye in this, paypal requires time and not affect the charge back which is your last attempt to get your money back!

Knowing the board or emitter Center Lines of it’s layout is one thing, laying it out on the emitter shelf by hand and then machining or drilling and tapping the hold down holes is a different matter. I didn’t see any milling machines like a Bridgeport in Vinhs work shop. where he could indicate the diameter of the heat sink and coordinately use the handles or a read out to put the holes in for the board? Unless he is having it done on the outside, he does have a buddy that owns a machine shop. Or he could of had a jig made, where all you do is drop the jig in and then drop the board into it and transfer the holes that way, either way it would have to be some what precise because just a bit off makes a really big difference with this very large reflector.

How many Big Reflectors have you tuned Enderman in a fixed head/reflector light?

It’s simple, you know the dimensions of the MCPCB, and the diameter of the shelf, so you just do some math to measure the distance you want between each of the 4 sides of the MCPCB and the side of the shelf.
All you need is a calculator, a caliper, and scribe or pen/pencil.
The hard part is not centering the MCPCB on the flashlight, it is centering the reflector over the MCPCB, since there is no centering ring, so it can easily shift when tightening the head.

It actually does not need to be perfectly centred either to get the highest intensity either.
The amount of lux projected into the spot is uniform, so it really only makes a difference to how straight the beam appears to your eyes when exiting the flashlight.

Oh, it’s also possible to simply mark where you need the holes on the shelf, center punch, and drill+tap them on a drill press.
I don’t think vinh used screws though, it seems like just thermal adhesive from the pics.

From the last batch of reflectors, only 50 got used.
The other 75 to 100 reflectors?

They are supposed to be stockpiled for the upcoming Group Buy.


Yeah I read some of your build, you should/could have external adjustment with your recoil light seeing that the emitter is on the OUTSIDE of the reflector, didn’t you have to open up the holes in one or the other (the reflector) or both to make adjustments because your design, drawing, machining, or was it errors in the dimensional stack up of tolerances was off, to cause the need to tune your light better?? Or did the machinist just center punch and drill all the holes in all your parts he made for your lights? :smiley:

Once it’s glued you could be screwed, unless you have a way of keeping it in place while it’s curing…I tried glue once! :person_facepalming: Now I glue it after it’s been set and cycled hot enough for the thermal paste to hold it and just glue the edges.

I centerpunched and drilled the holes myself.
The reflector can be adjusted, the LED cannot.
The parts were cut by waterjet, there was just some holes I had to do by hand and I punched one in the wrong place :smiley:

Hi T_A, did Neal answer you already?

I can show all the information that I have

What I meant was - we need more info from Neal.

Has your light shipped or not?
Why did he send that email?
How much extra is the faster shipping option for you?
Did he already ask you for half of this extra amount?
If so, and you paid it, why is he now asking for more?
Does he think that you did not pay that extra shipping fee earlier?
Are his accounting records correct?

I don’t think there is anything you can do on your end. It is all up to Neal to answer these questions.

Your issue is one more thing on the spread sheet list he has to investigate.

Oh no, the old measure twice (before you center punch and drill) rule jumped up and bit you in the ass? :person_facepalming:

Are you still in Therapy or are you over this major error in common sense (you of all people) and are moving on with your life now I hope? :smiley:

Haahaa just messing with ya Enderman, Damn Fine job you did on both your lights! :beer:

It was always said that:
The shipment was included in the price
It would be sent by DHL Express in a single package or by registered mail in two packages

It is convenient that I clarify that:
I ordered it by DHL Express
I want it for DHL Express
Neal asked for half of the shipping fees and I paid it
Neal may be suggesting indirectly that I pay more but have not yet asked for it directly

Lumintop sells the GT for €330 incl shipping on AliExpress and €396 with batteries. Led color is cold white

Special method of centering and focusing take Vinh two days for each GTvn. That’s what i read from his thread.

Sorry i didn’t click on it, i didn’t know there is official Lumintop store there.

To all those who already receive their GT, stay calm please. You should stay calmer than us who haven’t received any tracking number yet. Stay cool everyone, it’s just flashlight. You can always request refund if you already don’t trust Neal or Lumintop.

This was talked about here yesterday.

BTW, I don’t think it is cool white. That might be an error under the option list.

The description lists it as neutral white.

Plus they are using Texas_Ace’s emitter chart for the 4000k stock led. So I don’t think they changed emitters.

I don’t like the green rings.

All the last 50 orders have been sent, does anyone have this information? I still have not received a track number, no response from Neal, no reports of additional payment for shipping, nothing at all, only one incorrect dhl track number sent to the US …

lol I actually did measure twice and see that the line i scribed was in the wrong place, then scribed a new line, then forgot I had made a new one and punched on the old one :C
hahaha
