LEGION II: A 3*18650 SSC P7 light with advanced UI [COMING]

[neoseikan]

Hello All. I got the idea about a P7 light about one year ago, and started this project in the summer of 2008.
Many things changed now.

*It's no longer a SSC P7 light. The led in Legion II is CREE MC-E.
*It's not a thrower like single die DBS/A10. but it can beat all the other MC-E lights with its powerful output.


Bezel diameter: 53mm (Wolfeyes storm: 62.2mm)

More specs will be here later.

There is a video about it:

Enjoy it before I post more!

3 X 18650 seems to be abit long in the hand to me perhaps a 2 X 18650 with the option of an extenstion tube like the C3 offers ? no idea if it is possable but jut a thought

good luck with the light, i look forward to seeing it.

WF-400 3W Cree Q2 LED Flashlight (18650) is one of my favorite lights

[KRS1]

Yeh two 18650 is long already, i prefer 1 but two i can forgive.

Run time ~2 hour or more is a bonus.

atleast 700 lumen is preferable.

throw

when would this project happen ?

im so interest in SSC p7 thrower

I believe we are talking about 3 18650s side by side, not end to end. That was the main complaint of the Legion I 6 RCR123s(3 rows of 2) instead of 3 18650s. Sounds very interesting.

Yes. 3*18650. Side by Side.
The tube dia. is about 43~45mm, I think it is acceptable, but your opinions?

[Wolf359]

Maglite d cell torch is approx 40mm and that feels a tad big in my hand, maybe because i am now use to smaller dia lights like the wf-400. what is the approx length of the tube . fancy mocking one up to see what it feels like properly.

The Wolf-Eyes Storm has 3 18650 side/side and it is a great fit in the hand. I'd love to see a light like this with a P7 and a new UI ! Go for it!

[Steve L]

With the new UI, no tail cap switch needed(a ring controls everything - including variable brightness), SSC P7, and 3 18650s(side by side). It sounds very promising indeed!!

+1. Yeah, make the battery arrangement similar to the wolf-eyes storm and you've got a winner. 2 x18650 would be insufficient power to drive the light to its fullest potential.

[Grumpy]

This light sounds like a great idea.

I really like the side by side battery configuration which makes the light shorter.

[LEDninja]

Why 3x18650? That is ~10V. You only need <4V to drive the LED.
Elektrolumens has successfully built 4xSSC_P4 with 3xC (Quadstar Phaser) and 3xSSC_P4 (Firelion-III) with a single 18650.
Maybe it is time to redesign the circuitry.

[neoseikan]

Hi, LEDninja, it will be 3.6V, not ~10v.
What we need is a 2800mA output circuit.

One of the problems with your lights is the # of batteries required. When you 1st joined CPF and proposed a 4xCR123A light there was a lot of resistance because people only have 2 bay chargers. 4xCR123A or 2x18650 was better because 2 bay 18650 chargers are available. But 3x18650 means 2 chargers!

You need to find a circuit that is 6V in 3.6V 3A out. Instead of 9V in 3.6V 3A out.
Or use PWM. Finding the right power switching transistor/IGBT to switch 3+ amps might be a challenge but I have bought adjustable frequency drives running 100+HP motors so I know they exist.
Anyway it is time for your circuit designer to go back to the drawing board.

[jirik_cz]

LEDninja: With only one 18650 battery you will get less than 1 hour runtime on full brightness with SSC P7. If you want high brightness and decent runtime you need more than one 18650 battery. 3x18650 is good for me.

[greenstuffs]

Can't wait to see the pics i'm deffinitly very interested for 1.

[jzmtl]

How about 3x 18650 end to to end, then make the whole thing out of stainless steel with thick tube wall, then epoxy everything to make it completely shock proof?

You can see where this is going.

Oh yes - I like your thinking

[Grumpy]

3x batteries would make for great runtime an still have a small package.
The chargers that AW sells work great and don't cost much.
I would not be interested if this were a 1 or 2 cell light.
I would not be interested if they were end to end.

With the batteries side by side as originally intended one could place this light in a coat pocket easily like Mac's Sceptre. That is what I liked about the Sceptre so much. A lot of light in a small (short) package.

There are many who produce lights with the longggggggggggg tubes.
They do not interest me.

Maybe it would be possible to design the circuit in such a manner that it would work off 1,2 or 3 cells. Depending on how the light is designed to hold the batteries, you may not even need dummy cells. Just put as many batteries in it as you want.

If runs from 3.6 volt this probably would not be hard to do.

[sledhead]

The WE Storm charges the batteries right in the magazine, no seperate charger needed! Just plug the AC adaptor into the battery magazine. This would be a great feature to have.

+1. Yeah, make the battery arrangement similar to the wolf-eyes storm and you've got a winner. 2 x18650 would be insufficient power to drive the light to its fullest potential.

Two batteries would easily run the P7 flat out but I do agree a three pack similar to the WE Boxer/M300 would be a great setup.

Here's what I want to know... Is it possible to make the light EXTERNALLY rechargeable via charging jack? That would solve the 2 bay, 3 battery dilemma. Also, parallel LiIons would self balance during charging.

[KRS1]

How much would this gem cost as in just a ball park ?

Interested in this puppy

[Stereodude]

I'd like to know this as well. Is this a ~$300 light?

[Jarl]

My thoughts: 900 lumens, throw. (come on, you've got 43mm diameter! How can you not turn this into a laser )

Sounds great if the price is reasonable.

[rizky_p]

I think instead of paralel 18650 i prefer a single D size lithium, it is not available other than from KD at the moment but it would be quite nice IMO as an option.

WF-400 3W Cree Q2 LED Flashlight (18650) is one of my favorite lights

that is one of my favorite as well, bright with full battery and throw like crazy for the size. I wish it has a constant current driver..

[saabluster]

The original one(which I own) cost $200 when it first came out if I'm remembering correctly. So I would expect the new one to be in that ball park.

[neoseikan]

We have started the works on reflector and batteries holder.
P7 is a great LED,
Even at 700mA, it is much brighter than a Q5 at 700mA.

[monanza]

This looks to be a very light. The UI is pretty . If you were to provide a D-cell adapter then users can choose a 3x18650 or 1x32600. 3x18650 have the runtime and availability advantage at this time.

Charging in the magazine is a great idea but what would the charge time be I wonder?
