EDIT: Prototype V2 testing has been added on page 3 at Post 63
Ok, as many of you know I have been involved with the BLF Giggles project for some time now (The “BLF GT” for people without a sense of humor).
Well I posted a review in the Giggles Thread but it had not been officially christened at that point. That has been fixed now with a bit of laser engraving.
I present you with Giggles, The ultimate LED thrower flashlight, from this point forward, you shall address it by it’s proper name. 
Here is the Giggles Text that I used in a few different formats. Personally I would stretch it out another mm or 2 to fill out the flat area but otherwise I think it works great.
Here is the review from the Giggles thread:

Ok, my long tube prototype arrived yesterday. I opened it up and promptly dubbed it “Giggles” as sounds kept coming out of me that I had no control over.
So after putting some cells in Giggles I turned it on and it earned it’s name. It is a normal flashlight, except 3x the size in every way, it is a BLAST to use. The beam is very intense.
Time for more pics!
The overall fit and finish of the light is great, exactly as we designed it to be. Only major change externally for the production run is the addition of knurling.
The button is nice with good feedback, the ring was not included, I added that for a shoulder strap. The bezel didn’t want to screw down all the way at first but seems it is just a tight un-lubed o-ring. With some lube that was fixed and will be done on the production lights.
The rotating tailcap is great, very smooth, waterproof and works great. Threads are nice and square as well. Only issue with it is it will need a plastic isolator on the inside of the tailcap to ensure the cell carrier can not short out but that is an easy fix.
The glass lens is a very nice piece, very thick and clear with a good AR coating too boot!
It is a very nice MCPCB, I forgot to take measurements then but I can get some later, looks to be around 35mm and around 2mm thick I would guess.
The heat sinking fins look great, very beefy and functional as well.
The other side from the button has the tripod mount and a plug that can act as another sling connection point
The battery tube is nice and sturdy for sure, you could use this like a bat no problem, good square cut threads.
The cell carriers are a VERY nice start, lumintop has redesigned them for the production lights with double springs that should have much lower resistance and polarity protection. Very good cell carriers for future BLF lights.
They would also be pretty simple to convert to 2s2p or 4P with a simple OSHpark PCB swap.
The driver is working flawlessly, I will let DEL give you all the details on it but so far my testing has mirrored his. A very good regulated output with a low dropout voltage and no apparent heat issues with the driver, which means it should be up to the task of driving an xhp70.2 at upwards of 60W and ~6000+ lumens :sunglasses:
Threads on the head are also very good
The reflector is good for a prototype, but could be improved. The surface finish is a little on the rough side, it looks like machine marks are showing through slightly, Lumintop have told us this was simply a prototype issue and the final lights will have a better finish. So the throw numbers should improve slightly.
The focus is very good as well. Some basic testing showed only very minor gains at differnt focal lengths. Very good for a factory light I would say but I was scared to test it too much since I am out of xhp35 HI’s if I was to damage the LED manually holding the reflector.
Here are some pictures with a sling from my S70 installed on the GT,* it balanced very well with the long tube* but is still a tad head heavy, not enough to be a problem though. With the sling it works great for walking around and lighting things up at distance. Perfect hog light to spot them way off in open country.
I would be curios to see the short tube versions setup like this to compare.
Here it is with both carriers filled:
And here with only the rear carrier full:
Now for some comparisons to my other throwers, they are all using TA FET drivers, From left to right:
Astrulux S2 - C8 XP-L2 - Convoy L2 XP-L HI - Courui D01 XP-L HI - Convoy L2 with XHP35 HI - UF 1405 xhp35 HI - Convoy L6 xhp70 - BLF GT
No flashlight will ever look the same again.
A simpler shot:
Overall I am very pleased with this light as a first prototype!
Now for Giggles beamshots!
Keep in mind the camera was on semi-auto and it was VERY humid out this night, so the beam shows up much more then normal and it doesn’t show the throw as good as normal. It looks cool though!
Giggles blows everything else out of the water by a large margin!
Here is Giggles aimed about 300-350ft away (tried to get some longer range shots but it was way too humid and the beam washed out the image before you could see the reflection, looked cool though, looked like a light saber!).
I edited the pictures since posting them in the Giggles thread in order to make them closer to what the eye saw, not perfect by any means, the humidity just made it impossible to get good beamshots but better.
Convoy L2 with XP-L HI
Pay attention to these 2 Convoy L2 beamshots, they are exactly the same light, the only differnce between them is the XHP35 below vs the XP-L HI above.
Also notice that the XHP35 is a warmer tint and even though the technical throw numbers are about the same, you can see things at range far better. The difference is even more noticeable in person. So keep this in mine, warmer is better for real world throw even if the Lux meter says differently, it sees light differently then our human Eyes.
Convoy L2 with xhp35 HI
Convoy L6 with XHP70 3A and TA FET driver at around 6,000 luemens
Cometa:
And my High CRI Triple XP-G3 3000 lumen Convoy S8 EDC frankenlight for comparison
The GT beam in nearly fog like humidity:
Another GT beamshot from a distance:
Comparison with several other throwers, I think the order goes like this:
XHP35 HI L2 - XP-L HI L2 - BLF GT - Small 2s zoomie - XHP35 HI 1405 - Cometa
Some tent beam shots to show the beam at different exposures:
May the Giggles be with you.
