so is the board copper? that grey always makes me think of the aluminum ones
I want to engrave this logo on the side like you did…
The mcpcb is most assuredly DTP copper. A VERY nice mcpcb for sure. Heavy, flat and solid.
The gray laser engraving is the aluminum body, the light body is aluminum, copper would be insanely heavy and super silly expensive, like $1000.
Interesting design, could look good. Obiously it could not have the colors if it is engraved but I suppose you could have it printed on the light as well. Lots of places do that but printing doesn’t last as long.
In fact places like Fastsigns and other made to order sign shops might be able to do laser engraving locally now days, they say they can print on anything.
It is worth checking into for anyone that wants to get their own light engraved. I will include the text I used for engraving below for anyone to copy.
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.
yes i’m on the first list and saw the specs but i always freak out when i see a light with the led on a grey board. thank you
When I saw this post, I thought “CRAP! Yet another light to buy.”
When I realized I was already on the list, I thought, “CRAP, one less light to buy!” 
Keep safe in all the crazy weather, TA and the rest of the BLF ohana in Texas!
MaxToch makes some really nice DTP copper MCPCB’s, and they are white to grey in color of the masking that is on top. Don’t see where the color has anything to do with it.
no big deal, relax. just double-checking. like i said, i’ve seen many aluminum ones that same color.
It’s ok. The masking on the mcpcb can be a whole array of colors. We are used to seeing red simply due to that being what we have seen the most around here. White and other colors are usually cheaper though so thats why you generally see these colors on production lights. Plus white will not cause any funny tint shifts if for some reason it is exposed.
Awesome light, but too expensive for me… :cry:
Sorry, I do not want to de-rail the extensive BLF-GT thread of The Miller any further but I would like you to know that:
Not only is the Giggles thread on the other forum closed, what you already knew, but now it is also removed.
Some members on the other forum are discussing this in the giggles thread
They are also discussing when the discussion about it will be removed (I could not bring myself to add a smiley).
All I can see is “batsignal ” when flashed in the clouds
Interesting, already closed.
For the record, I have not and will not make a penny off the sale of these lights. The only compensation I am getting for my work on the GT (along with the rest of the team) is a free GT to keep. Turns out it looks like I will end up with the prototype to keep as well. So I have no reason at all to care about how many sell except for an improved relationship with lumintop.
I did indeed PM Bullseyebill, I was waiting for a reply but now that the thread is removed I guess that answers my question.
Basically the between the lines explanation is that they can’t stand the idea of CPF members creating an account on BLF in order to sign up for the light. Which I can’t totally fault them for considering they are a for profit website. It doesn’t make sense to send people to an alternative website.
He did say that if a GB thread was opened on CPF then the thread could remain open but Miller doesn’t have time to deal with that with the Q8 just going live along with the GT and FW3 all going on already.
If things slow down and Miller has time it is possible we could open a GB thread on CPF for it and try again. Or if a CPF member wanted to volunteer to maintain a GB list on CPF you could contact miller about it, it is possible we could work it out that way but it is up to Miller since that is his department.
The end result is that it is their site, I will abide by their rules. I hold no hard feelings, just disappointment.
Just stick around here, we got cold beer and good company all day long :+1: :sunglasses: 
you are right, i was CPF member first when im searching for some reviews, their review is great and clear, i have to admit that
but when i want to go higher, deeper in flashlight, i move to here
take some time to get used to this forum, but now i feeeel great to be here
Well (maybe) except by some newcomers nobody here even plays with the thought that you (all) are being paid for all your hard work. But to outsiders it is maybe a strange concept that a small group of people work hard in order to give a large group of people some nice moments with their hobby. For which the large group is very gratefull, at least I am :+1:
First gut reaction when TA send me the PMs: “Let Vin buy them at full retail tweak focus a little, add a dedomed XHP35HD so they can buy what we make for $120-$160 with a Vin seal of approval for $500-$700”
But that is not fair, their house, their rules, simple as that.
So if a better down payment method then PMs with Paypal info can be found and the BLF PMs for the $111 price are send I see no reason not to offer it up there for the $150
+ 1 :+1:
As I live very close to the main Dutch airport I can get in serious trouble if I use this light when airplanes pass. The good thing is if the airport lights fail, the dutch giggles owners can take over with their new GT's.....
Here are some prototype V2 updates:
Condensed cliff notes version:
- New reflector is much improved, has some minor specs that don’t affect the beam that are already being worked on by lumintop
- Centering ring is good, just needs to be careful when installing
- Kurling on battery tube, fantastic, could not ask for more
- Lighted switch, 223ua of parasitic drain, about 3 years of standby time with 8 cells
- New Battery carriers are all metal now, double springs, much lower resistance and better design. The button top spring could use a brass or copper coating, needs arrows on all 4 rods
- Tailcap sticker for protection against reverse installed cell carriers could be improved but is acceptable as is if it had to, going to see if they can make a cutout to prevent the V+ from even being able to hit the tailcap, that would fix it
Overall I would say that Giggles is almost ready for approval with minor tweaks that would not need another prototype.
The last thing that needs to be settled is the LED. I am going to try to test those out later today or tomorrow.
Ok, here are my initial impressions of Giggles V2 as I start breaking it down.
The reflector is a massive improvement, while there is still some minor ringing when held close to a flat surface it is much much better then before. The surface smoothness is now good enough to go into production IMO. Not perfect but really good for such a large reflector at this price point. Further improvements would have minimal if any noticeable improvements to the beam.
There are some minor imperfections on the reflector, minor specs, looks like some dust got caught in the coating process, Lumintop has already confirmed that they are working to fix this for the production run. They are just cosmetic though, they are so small they would have no effect on the actual throw.
So how does this boil down to real world use? VOB still has the V1 prototype (I plan to send him the V2 proto once I am done with it so he can compare them on video), so I can’t compare them side by side. I am going off memory but the hotspot does seem more defined, kind of like the difference between a very mild orange peel and a SMO reflector.
I took some throw readings but due to the very high humidity in Texas my readings are never as good as others and they can vary by quite a bit depending on the day.
In this case it does seem to be averaging roughly ~5% higher than the V1 reflector, which is about what I would expect. Although this LED is different then the V1 so take these numbers with a grain of salt.
Overall I would give the reflector an A, still minor improvements to be made in getting rid of the specs but a passing grade none the less.
The new centering ring also appears to work good, although they will still need to make sure that the production versions are careful with the install. My LED had some minor damage to the silicone but luckily I checked it before tuning the light on and after cleaning it was fine. This is just from being removed and installed several times I am sure, this light has obviously been used for a lot of prototyping.
The next biggest change is the Kurling. All I can say is wow, it is amazing. Somehow it manages to add a surprising amount of grip without feeling abrasive. In fact it feels really good to hold. It also looks fantastic.
A+ on the kurling, could not ask for more.
The tailcap has an added sticker on the inside to provide electrical isolation from the cell carriers, it looks good as well. Not sure how well it will hold up over the long term though. Luckily even if it is missing it would not cause an issue unless the carriers are inserted backwards.
With the new carrier design I think the best option would be to make an indention in the tailcap to prevent the button top of the carrier from being able to contact the tailcap even if it was inserted backwards. There should be plenty of room and would be a simple fix.
It would be acceptable as is if needed though.
I think they forgot to install an o-ring in the tailcap ring, so it rattles a bit but that is just a prototype issue. This needs to be in the final version for sure.
Now for the carriers.
They are very nice, all metal construction and double springs this time.
The polarity protection is also very well done, I like the U shaped cutout, it makes it easier to insert and remove the cells. They did end up soldering the protection PCB to the base PCB for some reason. Not sure why they did this. It can be undone easily with a soldering iron through so not a problem for those that don’t want it. All you need is a $2 iron to do that.
Spring testing is very good as well. The losses in the spring > trace > contact for next cell is only around 40mv at full height (no compression of the springs). If I compress the springs that drops down to around 15mv at max compression (aka, if you used protected cells) or it looks like around 30mv at “normal” cell compression heights.
So voltage loss at 2.5A is less then 0.2v for all 4 springs. Much better then the first carrier.
The “button top spring” on the top of the carrier is not quite as good as the others but about the only improvement it could have is a copper/brass coating, otherwise the spring is about as good as it can get in the space it has. I measured about 75mv voltage drop for the complete connection from the bottom of the carrier to the top.
So grad total the voltage drop in a single carrier at 2.5A should be less then 0.3v and with springs compressed in actual use it should be closer to 0.2V.
That is perfectly acceptable and once again a passing A grade. A brass or copper coating on the button top spring would be nice to see. Also it needs arrows on each “rod” showing the correct way to insert the carrier.
This is the button top spring that could use a copper or brass coating:
The threads and all the other parts of the light are still just as good as the first prototype
The driver firmware appears to be the wrong version, it looks to be using the Q8 ramp table if I had to guess. This should be easily correctable, I am waiting for Tom to get back to me on what version I need to flash to it, otherwise the driver appears to work fine. I will test further once I have the correct firmware.
The indicator LED’s work good. I measured a total of 223ua of parasitic drain with the driver in sleep mode and the indicator LED on. This means that with both carriers full it will have around 3 years of standby time before draining the batteries. I think that is acceptable. It is also not nearly as bright as the Q8 which is nice for night time use. It can be adjusted by the end user by swapping a resistor if they wanted it brighter or they could switch to a clear cover.
Overall an A grade here, this is the most universal setup I can think of, brighter would drain more power then I would like and some people don’t like it that bright and dimmer would make it less useful in some cases.
It does not look quite this bright in person:
So overall this light is basically ready for approval. Just a few minor details to hash out.
Here are a some random pictures to keep you entertained while that happens:
