The BLF GT70 "Giggle Monster" is here! 7,500lumens, 1,500m throw! Group buy Closed!

I know my 4” tube is a bit small for the blf gt. I am getting 5850 lumen @ turn on. ( 5 seconds )… is that what you guys getting ?

Button tops are sold by different companies and can vary in height slightly.

Here is a pic where I removed one from a different battery. You can see they are made from a thin metal and are fairly easy to dent or bend.

It’s total height is about 1.5mm. I think about 1.3mm is what sticks out, but it depends on the wrapper.

The GT carrier needs about 1mm. I don’t think I actually measured it. It’s not a big gap.

If your not sure it is making contact, just measured the carriers voltage. If one or more are not touching, there will be zero voltage.

I have the 3.5in and I get around 5200 lumen at turn on, so your numbers look good to me!

Yep… I noticed the exact same thing T18. The button tops on those were to short for my liking too. They barely make contact…
And I mean barely. :wink:

Is there a group buy for that Tshirt?

Neal wearing a UI diagram I made, because of a joke which went a bit too far during the BLF A6 project. I think he was going to send me one, but never did.

Anyway, it must have been a prototype or something, since it seems to be missing some dotted lines.

How old is Neal? He looks like he’s 12.

TK, yes that was supposed to be the proto and the shirts were to be made for sale here at BLF in your honor and the proceeds were to go to you and Neal to the best of my recollection,
He was still at BG then and I think they got word of it and Neal stopped responding and the shirt just fizzled out and we never heard anything about it again, what a bummer it was. You sure hit a home run with that A6 UI.

I spent all night trying to figure out what happened with that one cell of mine and I found out but it’s nearly 5:30 am here and I am beat so I’ll tell you later what I found.
I didn’t know there were two springs and all springs I’ve seen have a 90 degree bend on the end, but not these outer springs so I got a huge slice on my finger and a big bloody Sunday for me, so heading to bed, will explain later about how sharp that spring wire is.
Good night all… :confounded:

Sorry if this has been answered, but any updates on the warm tint option?

There will not be a dedicated warm tint anytime soon. It is about a 50/50 chance of 4000k (which some might consider to be on the warm side) and 5000k at this point.

Okay how about neutral?

The neutral tint LED’s should be ordered this week. How long it will take them to get to lumintop is unknown at this time as it will depend on how and where they are ordered.

With this new shorter battery cradle, will a flat top battery make good contact/connection in it?

No, the new carriers still have the polarity protection boards installed. These would have to be removed to use flat top batteries.

Better to solder blob the batteries IMHO.

Hi.

My GT70 has the “new carrier” and battery over 67.30 mm will NOT fit…

If somebody else has measured something else please update.

I have an extra set of Stock BLF GT35 battery carriers (better fit for protected batteries) if someone in the U.S. wants to trade for their GT70 shorty carriers, they are like new…?

So what do you want to change?

If Lumintop keeps the new shorter carriers, I will remove “protected”.

Thank you!

Writing the manual and checking if everything is OK would be easier when the writer has a lamp to compare.
But there is never one. Only asking stuff via emails.
:wink:

I only mentioned that because there are some minor grammatical errors. Not because of the carriers. I was unaware a forum member wrote it. :smiley:

@TK
Oh, you made the shirt the wrong way.
Text and pics on a shirt like this need to be upside down, so you can read it.
