Will the final kcd typical to all lights of this monster be posted before we are given the go signal pm thereby starting the 5-day buy window? The reason l am asking is, for me, being already an owner of much smaller, lighter 1.034mcd aspheric thrower, l would hopefully expect this light to exceed it handily to justify the purchase of this light. Perhaps at least 1.2mcd as earlier mentioned?

Would be interested in what this mystery smaller, lighter aspheric thrower is. I know it's do-able, but probably not for this price. Also, probably it will not have a spot as big, or put out as much lumens.

Right now you can buy lights that throw further for sure, but cost and beam size tradeoffs.

The Deft X (Supbeam/Acebeam K40 as host, though much more expensive).

Ahhh - the Wrath of Ra right now seems like the best deal for a compact 1,000 Kcd aspheric, way cheaper than the Deft X was, and think'n smaller. But of course Michael has some stuff in the works, so should be exciting to see what he comes up with. He's also signed up here for a GT smile.

If you are talking about this one;

That looks just like a modded uniquefire 1508 to me

Yep, sure is. It is using the UF-1508 as the host, he even states that clearly. If you can mod, or know someone who can mod a 1508 host for 1 Mcd, go right ahead - I sure can't. A Deft X was just a modded K40 also...

We discussed them a while back, here: http://budgetlightforum.com/comment/1119365#comment-1119365, post #3023

BLF user scianiac is one of the partners. I've had some pm discussions with him - all seems legit, though haven't seen any independent reviews.

Thanks for the info Tom, i must have missed that.
Since i am not experienced in candelas and the rating (last time was in high school, which was a long time ago) it seems i have something to refresh and/or learn

If i understand you correct it is not as simple as changing the led, mcpcb, driver, bypasses, all the usual finetuning and even then it will not give 1Mcd?

1Mcd is best case scenario, you can see in the options that is is on average between 800 and 900 kcd.
It’s head diameter is pretty similar to the K40 so yes it should not be too difficult to mod it with a collar and Black Flat LED to get those numbers.
It’s a much smaller light though, so it’s heat dissipation will be potato-like and I doubt it can sustain 1Mcd for more than a minute or two.

Uhh, I'll disagree a little, but still it's all speculation. His higher model, more $$$, is a minimum of 900 kcd and he's built ones that measure 1,000 kcd. He actually measures and documents each individual unit made, like what Michael at OSTS did, and his #'s are taken at 30 seconds, measured at 6 meters. He's probably replaced the lens to something better, and they can cost some decent $$$. Also he's probably using a 3-4V LED, much lower power and lower lumens, and using a buck driver, so his setup will do much better in continuous runtime than typical.

For example, if he has a dedomed XP-G2 in there bucked down and at 5 amps, it's a pretty nice light engine for low power, low heat, longer runtimes, compared to other LED options, and can get really high throw #'s with proper optics.

I’ve built over 400 lights, the TK62 gave me fits, I managed some 535Kcd and traded it to Richard. The most I’ve ever acheived in Kcd, in any light, is 665Kcd. That was in the Olight SR-90 Intimidator. 1 million candela is not easy at all. Not at all.

That was with an Oslon Black Flat.
Obviously if you put such LED in a GT you will get far more than 1Mcd.

It is not only about the throw, but also about the usefulness. The GT has an xhp emitter, which is by no means the furthest throwing led, but is usable in the real life. IMHO there is no point in having a pencil like beam which is too small to actually illuminate anything and all it is good for is lux measurement.

One of my flashlights has a pencil thin beam but at 1km it has a nice usable spot about 10m in diameter.
It’s also good as a sky beam, lots of fun to look at.

You could argue that the usefulness of the GT is also very little due to it’s huge weight and size, but that’s not the point.
Everyone has a different definition of “useful”.

If someone wants to put a tiny LED in it to make a superthrower, let them.
We already know the GT will have an XHP35, that’s not what the discussion is about.

The nice thing about Giggles is that it is designed to be mod friendly. If you want to swap in a Flat Black for a major Lux boost, go for it!

If you want to swap in (or possibly buy direct at a later date if there is enough interest) an XHP70.2 for max lumen output, then go for it!

This will be the ultimate thrower host that is for darn sure. I could easily see modded versions getting 1.5mcd or much much better.

You are right guys, to each his own. While I can imagine modding mine with an xhp 70.2, there will surely be other BLFers willing to swap in an oslon black flat to turn the GT into a laser.

Michael Johnson (aka saabluster), the maker of my Deft-X, has the Rev Victor as successor already reaching 1.4mcd (same host, using the newer S4 bin XPG2 at that time) and both models are not over-driven and will run MORE than a minute, sustain it, at turbo, so doubt no more.

All the above are nice lights no doubt but the difference being they are all modified. This light is available to everyone as a stock light.
I cant wait to see what these wizards do with this light. Smile

Yup, but it is a much bigger light with a ton of cooling fins compared to the UF1508.
This is probably why the UF1508 is only 800-1000 kcd while the rev victor is nearing 1.4M.

At the beginning it was clear a smaller die led would give higher CD
The GT is not a pencil beam, it is a sharpie beam, not max CD, but easy to mod , not max lumens, again relatively easy to mod.
Yet stock throwing more then the king, TN42, making the GT the emperor Big Smile

Can’t wait for the mods, it ought to be a really nice foundation to build on Wink

I have accsess to a laser engraver locally but they are becoming more and more common. If you look around it is usually not that hard to get it done.

Check with your local community college. They may have a laser engraver (as well as other fun toys). I had to take a 2 hour class, but can now play with their toys. Smile

there is a local shop that has Co2 laser cutter(60w i guess), not sure if it can engrave on this light

The one I use is 50W so it should work fine. Doesn’t take that much power to cut through the ano.

Another place to check are “maker spaces” They can have laser cutters. Libraries are also starting to offer these kinds of services in some areas. Also check Craigslist, there is usually a shop that does it in most metro areas. Post a wanted ad if nothing comes up.

Laser cutters will get to be like 3D printers at some point, still a bit too costly to make them super common right now.

You may also want to check out “Fab Labs” which spun off of an MIT class called “How To Make (Almost) Anything”.

The following link is to search for Fab Labs around the globe.

i just remember i have a 3d printer, if i stick a 2.5w laser module, will it work?

Looks like there are two Fab Labs in Ho Chi Minh City, both with lasers. (One 40W and one unspecified.)

thanks mate, but as i said i want to do this myself, i have some lights that i want to engrave them too, the fablab you mentioned is quite far from my house, it takes about 1 hour to come there
