I migth do that too. Facepalm

I think KawiBoy1428 was the only one that had any smoke (on only one of his two lights). Mine didn’t. I haven’t heard anyone else say they had smoke (from excess flux residue). Hopefully if anyone else sees it, they will mention it.

The bezel is way harder to open then the head was to remove on both of my GT’s. The rubber mat worked to get both bezels off, but man what a PITA! I would have used my big strap wrench but it’s at work. It took everything I had to get those bezels off! Facepalm

Both are done now, I even changed the other GT’s emitter to the E2 3A I bought off Lexel both the de-domed E41A and the E2 3A are more to my liking. Wink

A few of my Throwers… 12 of them are XHP35’s…. Big Smile

Where is the balance point (Center of mass) in the GT?
Good question! I fashioned a simple ‘seesaw’ or ‘teeter-totter’ to find out. LOL

The center of the switch and the center of the tripod hole are exactly opposite each other.

Fully loaded with 8 Samsung 30Q button top cells, the balance point is 1 cm (3/8”) behind the center of the tripod hole.

With 4 cells in just the rear carrier, the balance point is at the rear edge of the tripod hole.

With 4 cells in just the front carrier, the balance point is at the front edge of the tripod hole.

This means the center of mass moves just 1.5 cm (5/8”) in the cases of both extremes.

In short, the balance point is at (or just behind) the tripod hole or switch.

… ToyKeeper …

I do lots of stuff on BLF, but I’m not on the BLF GT team.

For the GT I’ve mostly just chatted in this thread sometimes, and I’m hoping to port some firmware to the GT soon (FSM and its UIs). This will allow it to operate like a Zebralight, an Olight, a Meteor, or run Anduril (my current favorite UI, similar to Narsil).

We already have a Team account for the GT, it is what was used to post the support thread.

The issue now is that making a new thread at this point would lead to more work for the team with minimal effects on the usefulness for everyone else. I mean people still ask to be added to the list in my review thread, who says people will find and read a separate thread for the GT?

Plus there is the case of it needing to be put together and none of the team has time for that right now. I just started eating solid food again, it will be a little bit before I am ready to do anything more then try to keep up with reading the posts.

I think it would be easier if anything to add a FAQ to the support thread with the latest status updated, since that thread already exists.

After all the nice photos people have posted of their BLF, I might want to order another. When is the cutoff for the $157 price? I want to see if my first arrived before I order another.

Ceiling bounce is not a very good way to judge lumen output, its not going to be very accurate

This is another point, the concentrated beam of the GT could also effect the way the light bounced and cause less light to reflect at all, skewing your readings further.

Basically the LED in the GT is driven as hard as is practical for a production light, harder then most other lights, including the tn42 (it is driven at 2.25A IIRC). So you won’t get much more out of another LED, I wish we could. The only real improvement is going with an E2 bin LED for a 7% improvement. Which we could not source for the GT due to a shortage of NW E2 LED’s.

That makes sense to me. Thanks. I found it impressive that i still hit 1.2 million cd even with a NW emitter. I wonder what it would read with a led closer to cool white. my meter is crazy bias to cool white leds for measuring throw. but i LOVE the NW emitter so ill leave it as is. That is till i can get a CFT 90 in there. 5000 lumens and 1.6 ish million cd sounds amazing(just a guess). it wont be cheap but if a driver can be made for it to drive it to its max potential im all in.


a VERY NW emitter to boot.
it makes my other nw lights look cool white

UPDATES: It appears that the first shipment went out by region instead of the exact order in which we paid for cost reasons. Initial quality has been fantastic.

The first shipment of lights (168 total) shipped on Dec 23. This was a pallet going to the USA from the first 576th person on the paid list that did not include batteries. Tracking numbers went out on Dec 27 and lights started arriving to customers on Dec 29th. DHL shipping was very fast.

There should be a European order going out in January.

The next group to purchase lights (#1000 and up on the list) will get their emails mid January instead of early January in order to let Neal get caught up with current orders.

Here are 2 beam shots in my usual location.

That hotspot is tiny compared to the L6 with xhp50.2 and xhp70.2. I’m also surprised by how big the corona is.

While admiring our GTs shortly after unboxing, my friend wondered how the tailcap and its spinning lanyard ring worked. I don’t recall seeing photos of it disassembled.

As I mentioned earlier, mine was much more difficult to turn than my friend’s. It certainly was not ‘twirlable’ like the prototype in VOB’s video.

Click play to watch the section of Matt’s video that shows the tailcap lanyard ring.

Curiosity got the best of me today, and I decided to find out how the tailcap was constructed, and why mine was hard to spin.

Click the photos to embiggen.

The sticker inside the tailcap hides four blind holes. The scratches are my fault.

I used my small needle nose pliers to loosen the inner piece. It’s reverse threaded.

The tailcap is made of three parts and two o-rings.

The large piece has an o-ring that the spinning ring slides along.

The o-ring was not seated properly in the groove and was partially pinched. I had removed and reinstalled it before these photos.

I removed both o-rings, lubricated them, and reinstalled them.

After reassembling the tailcap, my lanyard ring spins much easier. I think it has just the right amount of resistance.

I reinstalled the sticker inside the tailcap to help protect the anodizing and to further insulate the rear carrier.

Hahaa did you not read what T/A said about LUX numbers?

The LED in the GT is overdriven already. It is run at 2.5A in turbo which is about as high as is practical before rapidly diminishing returns.

You could swap the sense resistor and raise it to 3A if you really wanted but you would only gain a small amount for the first little bit until the LED heated up.

The biggest reason for the lower readings then other lights is that the GT is using a Neutral white 4000k emitter vs the CW ~6500k emitter in most other lights.

The lux meters we use are biased to the cooler white range and will artificially inflate those numbers.

The stock LED is a D4 bin. The highest bin that Cree lists in the data sheet is E2, which is 1 bin above D4. Or about 7% higher output. So 7% higher is about the most you can expect with another LED, everything else should be the meter bias.

So my LUX numbers are pretty meaningless since they are CW now and not NW. Facepalm

Too freaking cold for beamshots, but I’ll see what I can do once the temp gets back above zero one of these nights! I do have to travel a bit to the country to get good ones Wink Thumbs Up

Think they weren’t getting the numbers they were looking for. And narrowed it down to efficiency/passthrough/flow through the carriers.

Yes, they got canned. The extra springs under the half circle pieces added too much electrical resistance. They were probably cheaper to produce since the ends were made of plastic, but in the end the went back to their older style carrier. Similar to the one from their SD75 model seen below.

Coyotehawk will add your name to his sign up list. You’ll see your name when he does the next update. It will be sometime mid January when you are emailed with the details of where to go and how to order.

You can also buy 8 of the Samsung 35E batteries for $40 at the same time as you buy the light. No sign up necessary for those. There are plenty of batteries in stock. 

Welcome to BLF.
