Thanks!
More shots from a better camera will follow in time.
After being broken for the last half year, the light has now been fixed. The insulation of the cables running through the copper cylinder to the LED had been damaged by sharp edges which led to a short circuit. This killed the LED.
Michael (RC-Lights) used a steel rope coated in chalk and tooth paste to smoothen the edges of the holes after re-drilling them at an angle by pulling it through a few hundred times. The new cables were also put into shrink tube to make the insulation more robust. This should be enough to never have this problem again.
I sent him three more Black Flat LEDs which he tested and compared with one of the older ones. One them was better than all of the other LEDs (so it's the best of nine). He also switched out the sense resistor to reduce the current from 5A to 4.5A. This keeps the LED from going blue.
After refocusing the light now does 1.7Mcd measured at 14m! 
In addition to this Michael did the following things:
- Replaced the second electronic switch with a different type. Now both of them are used for the ramping, one for ramping up and one for ramping down
- Following the recommendation of the manufacturer, a 4.7uF capacitor was connected in parallel to the leads going from the battery to the driver to prevent voltage spikes
- Additional cables were soldered to the Stripe dimmer module to make connecting it to the USB programmer easier
- A new firmware was flashed onto the dimmer which raises the PWM frequency from 2kHz to 14kHz to prevent the high-pitched buzz coming from it when the light was dimmed
- Repaired the cracked, plastic bezel with epoxy
- Replaced the UCLp lens with a new one which no longer has a hole in the middle and doesn't have any cracks
The dimmer connected to the USB programmer:
After this the light was finally finished. It was time to use it.
Here are some beamshots comparing the light to Michael's Superthrower, which has an Olight SR-90 reflector (88mm) and a Cree XP-L HI. It does around 650kcd. The performance of Michael's light is very similar to the Thrunite TN42.
First a shorter distance, maybe around 100m:
Next, the main target was an unlit cell phone mast at a distance of 1.2km (0.75mi).

At last a pic with 30s exposure just for fun:
Surely more pictures will follow. :)
Nice pictures…
I am sure that ladies will like look of Michael superthrower.
Nice 
Unfortunately your light is still #23 in longest throwing flashlights because there was nobody else between 1.5 and 1.7Mcd 
lol
Still a great improvement for using the same LED.
Thanks guys!
Well, yes. We didn’t do this to be higher up on the list. The best remaining LED of the first six did not reach the same luminance as the dead LED. I wanted the light to be as good as it was back in the summer, when it was first built.
Any chance you might sell your new toy? Just asking. It looks amazing. How does it compare to the GT? Performance wise? Would you guys be willing to make another monster thrower for sale?
Nope, never! I waited years for this to become reality and it has now taken 10 months since the project started. I only had the light for close to two weeks before it broke and haven’t gotten it back yet since it was repaired.
It weighs about half as much as the GT (only three batteries instead of eight, the head is lighter), throws a bit further, has a hotspot 1/5th the size and a much darker spill. It also never overheats and is perfectly regulated with any kind of 18650 until the batteries are empty. The driver of the GT has more U.I. features you can activate and play around with though.
Building another one would cost at least 1500$, probably more. Why would you want that when you can just buy the BLF GT for 1/10th the price and get similar or better performance?
I already have the GT. An amzing light indeed it is. But I just love throwers. I like collecting the best and brightest throwers out there.
I’m still waiting for someone to built a 3/4 million candela super thrower, with a least 6/8 K lumens, any chance you might be working on something like that? Most importantly, is the LED needed for such a project even exist yet?
6000-8000otf lumens with 3Mcd from one LED is currently only possible by combining a Luminus CFT-90 or Cree XHP70.2 with a very large optic or reflector. Those are practically the only LEDs which are that bright. The CFT-90 is the much better suited of the two. It reaches almost the same luminance as the Black Flat I used in my light here, but with 8-times the die size.
I finally have the light back in my hands. Before sending it back Michael also took some "artsy" beamshots. The light is great for long exposure times because of the rather dark spill.
Nobody up there has answered yet...
They are addictive, the pictures that is. :+1:
It's time for more pictures. The plug in the lens is finally gone!
closer:
even closer...
Here you can see two fine details - the Osram Black Flat is a very thin LED, the Die is lower than that of Cree LEDs. Because of this Michael used especially flat screws and copper sheet metal (insulated with shrink tube) instead of round wires to block the smallest amount of light possible.
What follows is something that I really wanted to do with this light even though it's quite difficult: a picture where the yellow reflection of the LED die fills up the entire reflector (from this point on the real lumunious intensity can be measured because the beam has assumed its final form).
The camera was over 10m (32ft) away.
With 150mm tele
The money shot:
Here the light was dimmed to 1% and the Camera was at its absolute darkest settings (during the day!):
This is what it looks like to be lit up from this distance during the day at max brightness (not very nice):
Amazing flashlight and pictures! A lot of time, effort, and (a little) money spent on a truly one-of-a-kind flashlight. Do you have plans for another one, or are you just going to admire this one for awhile?
Thanks. I don’t have the need or want to have Michael build another one. Also he wouldn’t do it anyhow (it took much longer than anticipated) and I don’t just have spare Maxabeam heads lying around. 
Now that is a flashlight and one tough mod. Michael is very talented guy.
Still missing were the dimensions and the wheight:
- Length: 32.4cm (12.8in)
- Diameter of head: 14.5cm (5.7in)
- Diameter of tailcap: 4.9cm (1.8in)
- Wheight with batteries: 1.445kg (3.2lbs)
Wheight of some of the parts:
- Head: ~600g (1.3lbs)
- Body: ~541g (1.2lbs)
- Tailcap: 103g (3.6oz)
- Battery holder: 56.7g (2oz)
- Batteries: 144.1g (5.1oz)
The BLF GT is around 60% heavier, mainly because of its five additional batteries and the material around them.
Time for more beamshots. I'm getting gloser to my goal of 2.6km (1.62mi) beamshots.
To make these shots seem more realistic they need be viewed in fullscreen mode on a large monitor in a dark room. This way much more detail can be seen.

Cell-phone beamshot very close to the light (makes the beam look wide):

A darker target next to the building (1500m - 0.93mi) (with my own eyes I couldn't see this being lit up):

Great job. Beautiful light.
Show them direct comparison with 300 kcd Brinyte you have?
This?
It's a bit too close actually, the beam of Excalibur isn't fully formed yet.
