Great job Kronos! Your light looks great! But the thicker floor plate isnt going to help a whole lot in transferring heat through the head because its not the thermal bottleneck. What are the chances of making the head a solid 1 piece unit for a few dollars more, and keeping the aluminum walls thick to follow the contours of the reflector to better transfer heat through the head? All that dead air between the reflector and the head should be solid aluminum, as thick as possible, without any right angles, using only radius cuts, and of a 1 pc design to assist in maximum cooling. Any compromise here limits heat transfer, which heats the base of the floor plate assembly… which in turn heats up the battery tube and the cells. Then we wind up with another powerful light, where the battery tube is almost as hot as the head after a full power run. This has been the limitation in almost every high powered light sold up to this point. Now you have a chance to address that problem directly before its too late. As it is now, the light has the same thermal bottleneck as the S70 (and most others), which survives at 5 amps. Since you’re almost doubling the amps, I think you’d do much better in asking ThorFire if they can accommodate us. Every little bit is going to count at those power levels, and cells shouldn’t be used as heat sinks for such an awesome light that you’ve created!

Thoughts?

It is an idea we can certainly look into. To make it happen would require a redesign of the head/reflector and possibly a new round of samples/prototypes (potentially more delays)…but we’ll see what we can come up with!

Here are some simpler to employ ideas. Just leave some extra mass where avaliable (the red areas) assuming the driver cavity is not filled up by a big coil.

Then more surface area below the fins on the bottom part of the head. These are small changes, but could really help with cooling.

Check this out.

And also make the head in one piece, as most of the fins are just cosmetic…justbuyanL6

Maybe do a factory bypass on the springs like the L6. Possibly use braided copper instead of a wire.

You could even offer a hot rod version of this light with a FET driver. 11 or 12 amps would really be spittin out the lumens.

9 amps is not bad, though. What would that be in lumens, over 5,000? Pretty decent.

Also make sure the battery tube is long enough for both short, 65mm, and long, 70mm, batteries. I’m sure some folks would want to use the protected KeepPower 5200 cells which were a bit too long for the L6. They are good for at least 9.7 amps.

[Team_KRONOS]

There a lot of good ideas that have been posted…some of which we are looking at. I won’t make any promises on anything…but we are certainly open to improvements on this or future lights.

As far as the request for more information…much of that is up in the air and dependent upon how the latest prototype performs.

We will attempt to answer what we can in the next few days, and then provide much more information after we have tested the latest samples.

Pricing is not yet set in stone. We will price it as aggressively as possible considering features of the light.

Cheers,
krono

I do like what’s been done design wise with this K70, some tweaks for thermal management could allow it to become quite a flashlight.

K70 in for two

[SteveMidwest]

I would like to be added to the list for one as well. Team KRONOS.

Nice Kronos, thanks for addressing some questions, ecting to see what comes out of it!
it puts lots of questions on hold.

In the mean time, could you address these questions please?

1 question that has nothing to do with the expected prototype:

@The Miller

Who made these nice renders by the way?

1 question:

@ReManG

any chance on a ~4000K NW tint option?

thanks

Renders were done by TF. I think you mentioned something about us only having renders in your earlier post that has since been edited…but check the OP again…they’re not all renders. There are some pics mixed in of the protos that will be sent to us. :+1:

As of now, a different tint is not an option, but we would consider if there were enough interest.

[chrisc]

I’ve got to say I wasn’t sure if the below image was a render or a photo that was blown out with too much light - I thought it was a really good render.

[gregor]

Put me down for one please, thanks!

[Joat]

Put me down for one.

[gorb507]

interested depending on price, specs & UI

[The_Miller]

The renders look very life-like.
Ah yes so right now they left the top part of the head as used on the S70(s) makes sense.
Hope you get your prototypes soon!

[KawiBoy1428]

I like what I’m seeing, and I think I really want one of these, that Full Round Diamond (i detest flats) battery tube and tail cap really sets this light off, great job, please keep it up!

I would like to see you guy’s come up with something truly outrageous in the near future, because your team is not lacking in the talent department that’s for sure! :+1:

So put me down for one please!

Thanks and Rock On Team KRONOS!

[Tete]

One for me, please!

[uqs1000]

One please.

[pirate_joe_22]

in for one

@Muto

Feel the Love in the room

Yup…seems like old times…lol

[Team_KRONOS]

@stephenk

So let’s add a fan then for longer high output runtimes?

Or fill the void between the head and reflector with Prestone

Come on Dale…what’s a GB thread without a little drama and controversy?

Thanks. We’re working on some tweaks that the factory can live with.
