BLF Kronos X6/X5 GB - Group Buy now closed.

Btw, a Cu insert with fins, in a SS body will be an improvement and awesome looking, but it will still not nearly shed the amount of heat that a middle-of-the-road aluminium body can, in which the heat spreads over the body in no time, if flat black anodised it is even better.

(aluminium is just unbeatable for flashlight use: great heat capacity, great heat conductor, lightweight, cheap, machining is a piece of cake, it can be durably stained, it is strong enough for most purposes. If you are a flashlight enthousiast and have a distaste for aluminium, you really make it hard for yourself)

My only stainless steel light is the Convoy S7… and even with its relatively thin walls (half as thick as aluminum lights), it’s heavy and takes a while to cool down after being used. Having air flow doesn’t help it as much as it helps aluminum or copper. I love the idea of a steel X6, and I want one, but I worry about it shedding heat.

But we won’t have to worry about damaging the host! If its parts are exactly the same size and shape as the original it might actually be bullet-proof. It’ll be seriously indestructible.

There’s a common belief that titanium is stronger than steel. And, in one sense, it’s true — a given mass of titanium will support more weight than the same mass of steel. But titanium is much lighter, so it can be a lot thicker at the same weight. And titanium is generally softer so it scratches easier. If you go by volume instead of mass, steel is usually stronger.

Chances are, a steel X6 will still be in pretty good condition when your grandchildren inherit it… Unless you use it for target practice with armor-piercing rounds or store it in salt water when not being used.

BTW, the X6 is a great mod host. I’ve been meaning to mod one of mine for a while, and finally did it today.

I just modded my BLF EE X6 (CW, stock) to use a BLF A6 driver (FET+1) and a de-domed XP-G2 S2 1D. Before the mod (stock X6), it got:

  • 922 lm
  • 18.3 kcd / 270 m

After the mod, it gets:

  • 604 lm
  • 52.5 kcd / 458 m

I’m having a hard time focusing the beam though, so the lux could potentially get a little higher.

I don’t know what the lux would be like with XP-L and a FET+1 driver, or with XP-L HI. At a guess though, probably about 27 kcd for XP-L or maybe 45 kcd for XP-L HI. But these are only guesses.

1) SS/Copper (SS/Cu) set
2) NW
3) One set

Thanks again, for this great GB!

Thanks TK,

You know… what would be really interesting to me, is what would the throw be with a constant output (lets just say) 600lm output - comparing XP-G2 (dome-on) to a XP-L Hi?

How do their actual ‘optical’ die sizes compare?

Regardless, there has to be a winner… Who do you think it would be?

Thanks,

Put me down for
1 SS/Cu NW
1 Al NW

Thanks in advance.

Not a clue, but I bet it would be close (ish).

Please put me down for :

1 SS/Cu NW
1 Al WW

Thanks,
Mike

So your spot is you serial number? I have #20… could I request #57, or if you have #57 would you be willing to swap spots for #20?

1 SS/Cu nw
1 Al nw

Please and thank you! :slight_smile:

I'll take 2 sets of Al

cw and nw

thanks

FTR, I’ve hit 103Kcd before in a X6 with de-domed XP-G2. manxbuggy1 has that light. :wink:

Yeah, I’m actually kind of wondering what I did wrong to get only ~50 kcd. It might just need better focus, but I doubt that’s the whole story.

Regardless, it’s smaller and nicer than my C8 and it throws farther, so it’s a win.

one set of each.
spot #55 for each
NW for each

please include my name
1 ss/cu - NW
1 ss/cu - CW

thank you

If the first set doesn’t make 200, put me down for CW on the second set (that needs a minimum of 100)

1 HAIII Aluminum Set WW may change to NW later.
Watch the engineering specs on the 14500`s the new keepowers are getting fat and long
I have a few lights that they will not even start into the tube.

Krono: think you missed my signup for one alu set in post #93

Why not both? You know you want to .

All kidding aside - no way these lights do not make the minimums ,,,, and then some.

Kronos, Dale and JM put a lot of thought into these lights. It would be very difficult to find ways to improve them :) As a matter of fact if one were to buy the internals alone it would be more than the HAIII set......and when you consider the SS/Cu.....well, just try and buy Stainless or Copper hosts for $20 each - just not possible.

I’m thinking that the 14500 light will have to be an “IMR” only light, because of the amp draw.

IMRs come without protection, so Not fat.

The typical protected 14500 will only allow for about half of the draw for the FET driver.
