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

any info about off-center led, i’m really sad if they both reduce quality and speed

Congrats! Good news. $25 is under the €22 Why on earth puts Lumintop $30 on my packet? Neal wrote me before shipping it's $25 With 30 invoice you have no change to slip through customs.

Almost all of the prototype lights suffered a piece of the centering ring being scraped off and landing on the LED and caused it to burn.

It looks like to fix this they decided to center the reflector to the mcpcb instead of the LED itself. Which is a good idea and something we considered when this started.

This works fine in the vast majority of cases but in some the LED will reflow slightly off-center and cause an issue like you saw. The good news is that yours is about as bad as it can get and sometimes reassembling the light can fix it like it did in your case. It also should not be enough to make any noticeable difference in the throw of the light.

Seeing as the LED burning would kill the light, I would say this is a worthwhile tradeoff to make sure that doesn’t happen and completely kill the light.

I have replied to his PM. It is being handled.

Not to worry, nothing to do with the light itself.

Also, there would be no need to file a paypal dispute, you can simply request a refund at any time before it ships and we will be happy to send a full refund.

It is not an issue. It is by design. The carriers must be pressed against the driver in order to complete the connection, so there is some extra thread depth to make sure that can always happen.

So not to worry, your light is perfectly fine.

Yes, they ordered one of the lights I signed up for but never ordered.

Still waiting for it to be shipped like everyone else. No idea if I will hear more from them once they get it or not.

The black centering piece is machined from Delrin, oddly enough it isn’t perfectly symmetrical… if it’s touching the emitter it needs to be flipped around. All 4 that I have seen this has been true on.

I have paid on 2 dic 2017 03:37:29 PST time printed in the email from Paypal
The point of no return is 2 may 2018 04:37 PDT, frrm the transaction in Paypal

BUT…
I have paid the “reserve” on 26 ago 2017 13:18:53 PDT, the deadline is 22 feb 2018 12:18 PST

I have finally received my light yayy

It’s been a while since I visited this thread, and even longer since i remember reading this but iirc turbomode is entered by double clicking and should be visibly brighter than the top of the ramp? Am I remembering correctly? If it isn’t (which is my case) any reason that you can think of? To head off the question im using the cells from Neal that i purchased with the light

Thanks in advance

Sooooooo…… I signed up for the forum after the initial purchase group. I have yet to receive an email asking for down payment, etc. So am I just wasting my time at this point? Thanks.

Don’t worry, they would send you a refund if you requested it, there would be no need to file a paypal dispute.

You’re on the list. #1091.

Yes, the ramp stops at 2A and turbo goes to 2.5A.

Visually the difference is very minor and hard to notice unless you are looking for it (which is why we set the ramp to stop at 2A).

If the cells are low or have excessive voltage sag, then turbo will not be any brighter then the top of the ramp as it would have already dropped out of regulation.

This is where high drain cells do have benefits, they voltage sag less and allow it to maintain regulation longer.

I have yet to manage to open the head to adjust the centering ring, as it is on too tight.
The hotspot seems to be very far from a perfect circle so it might actually affect throw in this case, still thinking of how to remove this oversized head with whatever I have at home.

For those that have done so, any tips?

The 3rd batch of PM’s has not been sent out yet. It is looking like it might have to wait until after the Chinese new year at this point. Hopefully they can “stockpile” some reflectors to make shipping faster.

Thank you TA. I’m getting older and it may be my eyes aren’t sensistive enough to pick it up. There is a momentary dark period when it switches from the top of the ramp to turbo and it appears the same to me but im sure it’s just my vison.

Let me guess that only orders “with batteries” were declared as 30$ value …

I just sent a new email reminding Neal that it is absolutely necessary to have the AWL DHL for the customs declaration
Without doing this procedure I can not enter anything to the country

Just a thought… Use a large rubber band with a large pipe wrench. The Rubber Band protects the surface and also provides extra grip. The Pipe Wrench I am talking about is the one with the chain…

Zip Ties may also fill in for a similar “tool”
