Mount the proven Ledil Seanna in this light (or similar) and have a true giga thrower. Purchased in quantity should drop them to a fairly reasonable price. It could be surface mounted fairly cheaply, and with a bit of thought could be made into a decent looking light without a huge aluminum bowl to contain its 152mm width. Then considerations towards a true functional heatsink could finally be addressed once and for all, rather than another high powered light that overheats in 3 minutes at max power (which they all seem to do).

Thoughts?

Playing with my new TN42 yesterday (YAY!) One thing became clear pretty fast, with this much aluminum heat is not an issue, the GT has even more Wink

heheh
highly doubt it

BTW reaction of family to this thrower: wow, impressive. We could light up the castle at 820m easy.
They look forward to the GT.
Holding this bulky TN42 gave a better idea of the sheer size of the GT, dang it is gonna be big!

Isn’t that just a big fresnel lens with a mount?
From the specs sheet it seems much worse than a 100mm aspheric.
600cd/lm for the XP-G2, even driving it at 6A near 1500lm wouldn’t get the 1.45Mcd that I get with my aspheric.

What is the weight of the aspheric?

@TheMiller – Firstly, I appreciate all the effort that has gone into conjuring this light and the amount of time and resources you and many others have poured into it. For a conventional reflectored thrower, I truly hope it turns out to be the masterpiece everyone ever dreamed it would be. I apologize if this was the inappropriate thread to mention the Ledil Seanna. It would certainly be a departure from the conventional flashlight build, but I believe it can not be ignored when considering the maximum range potential of the XHP-35.

A quick search confirms there have been several frankenlights already built using the Ledil Seanna/XHP35 combo that approach just under 1 million cd using older binned 35 emitters. Cracking the 1M or 1.1M barrier should be a no-brainer with the latest bins, carefully tweaking the max current level at the bench, a sufficient direct thermal path utilizing a 1 piece integral heat sink, while enjoying the HD version of the XHP35 emitter (more lumens and better beam pattern), which this hybrid “reflector” seems to prefer. In a build using the Seanna, the heat sink should protrude as part of the floor-plate assembly, not part of the bezel. Then the thermal path will be direct and without any thermal bottle necks. The Seanna and heatsink are already proven off-the-shelf parts, easily attainable and simple to mod on a CNC. I think there is enough brain-power in this forum to make it not only highly functional, but also aesthetically pleasing… if not just plain bad-ass looking. The concept and production steps are far more simple than the conventional flashlight, if one has the tooling to implement it.

Unless I missed it, and someone actually tested a reflector + lens + XHP-35HD or HI that beat 1 million cd AND produced a pleasing and usable beam pattern, it looks like the Seanna with the HD emitter will completely murder any other option that I have yet to read about. Im still in for your light if it beats the range of the TN42 in real world performance, and doesn’t suffer the usual myriad of unforeseen congenital problems most other BLF derived flashlights have suffered. So I realize its a tall order with a very difficult path to success. But I think it could be so much more with the Seanna option. Granted, it would be a large departure from the style of huge “flashlight” we are all used to lugging or slinging. Most anything with 4 or more 18650’s is unwieldy by any standards. If you own one or even several dozen chunky lights (as many of us do), you typically chose the light for the task at hand to satisfy the anticipated situation. Among the larger variety, size and weight is usually a secondary consideration… which may be why we own so friggen many of the darn things!!

If this isnt the time or place, please feel free to shelf my blurbs and rethink it in a future project at your option. I hope someone at some point can make a go of it in a production flashlight. Then we can all enjoy something that just might force the flashlight industry to rethink their direction in order to compete with a new level of unmatched performance in this fun niche market. I wont go into great detail, but I have already approached several of the large manufactures to consider unlimited flagship thrower models, featuring pre-culminators that focus spill beam back into the emitter to further excite the phosphor, in conjunction with a Seanna style hybrid Fresnel and variable focal length for beam angle adjustment, removable emitter mounted copper pills for different tint emitter quick-changes and swappable conventional reflector and lantern head assemblies (just to scratch the surface). These are all well proven technologies that have been proven many times on several forums. The obvious benefit of a real heat sinking solution that isolates heat to only the heat sink itself would also be a first outside of the frankenlight world (excluding the extremely well executed and expensive Olight X6 Marauder).

Olight X6 Marauder

If youre interested, here’s a link to the Seanna datasheet PDF.

Concept from M4D M4X:

If anything else, maybe someone else will read this in your highly visible thread and have a go at it.

Thank you for reading.

Welcome to BLF!
Will update the list later.

About weight, I think that most zoomies with glass lens I have are a little bit heavier then similar sized reflector lights.

I am also very interested. If I can afford that monster of a light (and buying 8 new 18650s) im totally in.

Catadioptric is also an interesting matter. Someone could make bigger than Carclo

Good Find!

Might be a similar or same exact optic used in this flashlight: https://www.silentthunderordnance.com/shop/eye-of-sekhmet

The EOS is spec'd as having incredible throw from a package the size and shape of a cell phone, in a wood case no less - 260 kcd rated!

Catadioptric would be awesome, if one can be found or made better (suited for XHP35) than the Carclo.

Yep, 2.5 mcd would blow away a stock or modded TN42, that's for sure.... Interesting throwers...

It's a pricey aspheric lens, not your typical catalog Edmunds for example. He didn't specify the LED, just that it was a high luminous density. Maybe a dedomed XP-G2 or Black Flat?
