LS27 2 x 123 or 1 x 18650 Light?

[:)>]

Don,

I know that you get kind of cranky when people talk about stuff like this and I blame it mostly on your advancing age and senility:nana:

I am just kidding with you... I think you are tops even if you scold me for this thread:devil:

I would love to see a 2 x 123 or 1 x 18650 Lunasol 27 w/a body like the 27LT. For me, the 27 mm head is a little bit too large for EDC pocket carry, but it works wonderfully for so many other uses. I also don't think that I am alone in this secret desire

I am still sore at you for not making an updated HD45 too

The worst are those that know their deeds are evil and they do it regardless.

I am sure Don will kick your sorry rear end for this thread :nana:

This was really more of a selfless, altruistic act on my behalf. Knowing full well that there will be consequences, I posted it anyway to benefit the community

Goatee,

I have a LunaSol 27 Cx2 and find it a bit cumbersome with the level selection via head twist and momentary or constant on activation via tail. I think the PD system is much more appropriate for the x2 converters including the LunaSol driver pair. I think there are some who would be happy with this package but I believe the single cell and smaller package of the LunaSol 20 would be preferred by the vast majority. Given that I have plenty inventory of the LunaSol 20, I can't imagine that a more expensive and less well received LunaSol 27 Cx2 would fly and I can't get behind it personally regardless of its market acceptance or lack there of.

I still think about a 2x123 PD light on occasion and the one aluminum proto I have is real nice in hand and use but this would be a really expensive light in titanium and a certain mistake and not starter in aluminum.

I do want to do a 2x123 light and I have a proto that I have been using a lot lately underwater, during the day, for photo illumination. My criteria is for a high flux "ram" of light that has a large spot and narrow spill without too great of intensity variation from spot to fill; a concentrated flood if you will. I think the design would have the greatest range with a three speed driver and this rules out the x2 drivers.

I would be willing to consider an 18650 if I was aware of one that was available in the general market and qualified to meet the safety standards governing the other batteries being sold to general consumers. I am not aware of such a batery so it is likely that I will move forward with 2xCR123 as the battery system for this light. I still have a bunch of homework to do with this light and in adition to identifying an appropriate driver, I want to make sure I pick the best 4 die LED as a basis for it. This is not the light you are sugesting but it is one that I believe in and am interested in bringing forth.

Sounds Neat Don! How has the Piston held up? I ask because I assumed that the reason for not creating a 2x123 PD light was due to the added length and stress on the body.(harder to activate the momentary on such a long piston...)

Remind me to never have a suggestion.

Mayo,
My proto is a "stretched" brass piston in a 27LT body and the piston action is possibly better than that of the single CR123 pak. I am not aware of any additional stress and the longer piston in longer sleeve seems to reduce the friction and issues of a piston unsupported at the front end.

I am quite happy with the performance of the LunaSol 27 on a single battery and the one I have on the Cx2 driving the Cree at 917 mA is brighter than the stock LunaSol 27 but I am not certain that a smarter package on 2x123 wouldn't be with the drive at the same level as the single cell LunaSol 27 and gain in runtime as well as a larger and easier to hold light. I think this is a point Goatee is making and I agree with him. I think the 27LT is a good light in the hand and having one that is PD as well as twisty is really nice. I discussed the concept in detail with the machine shop probably over a year ago. Had things gone as planned and anticipated this year and were the economy still welcoming, a 2x123 PD pack might have come to be. As it now stands, there is a working sample in my drawer that gets me excited from time to time when I see it or a thread like this brings it to mind but beyond that, reality sets in and the clock keeps on ticking with new technology changing everything.

Thank you for the correction McGizmo, I await your next awesome creation!

Don,
Thought I would throw in my two cents.
I was thinking about the perfect beam for me yesterday and I think you have described it perfectly. I think a three speed is okay, but I don't like clickies. The UI like the Nitecore D10, would be a bit better for me.
Happy New Year,

back when i had a 27lt-s i always wanted to figure out a way to make it a pd

Frank,
Understood. Obviously I have to work with what is available to me in regards to electronics and with the small waves I do, I am in no position to dictate custom electronics. I personally don't like lights that don't go off completely when there is no light coming our the front and consequently that limits me to the PD design as I have been using it and a clickie switch if I seek more that two levels. I might even decide with this one light I have in mind that limiting it to one level makes the most sense. As I said, I still have much homework to do. One idea I keep coming back to is a simple twisty that can cycle through three levels by twisting off and on three times.

If the beam in my head is what you have in your head ... then I am really looking forward to this one.

You mean this one Bernie:nana:

See I told you I wouldn't blast it

Please excuse the empty trit slot, I haven't decided what color to use 2up Ti piston is a beeyotch to make:sweat:

[maxspeeds]

That is a beaut! It's just missing the long McGizmo ti clip

 

[dmdrewitt]

Beautiful Scott!! :thumbsup:

 

[TranquillityBase]

Me want long clip and yellow trit :twothumbs :help:

I had to give the Goat a little sumpin sumpin to look at

 

[easilyled]

Some more TB perfection based on the 27LT design but with a piston. Doesn't get much better.
