I built another one, this time with triple XP-L's. The single XP-L (dedomed) in the stock OP reflector does 27-28 lux ceiling bounce, about equal to what I get with a non-dedomed XM-L2 with a BLF driver. The triple 219B F6 does around 35 lux. Triple XP-L does 73. Seventy three!
A 'SecurityIng' SRK clone with a BLF-SRKDD driver, on four INR 25R's, only does 80 lux. A totally stock CNQG SRK gets utterly trounced at just 43 lux.
That sounds about right, based on my measurements. My original CNQG SRK (stock) measured at about 2200 lumens, which is only 1.3% different than your measurement. That means the triple-XP-L F6 would be getting somewhere around 3750 to 3850 lumens! (which, BTW, is beyond the range of my light box… I need to build an integrating sphere)
No wonder the cell voltage sags so much on turbo. 
That’s a little scary.
And when I get the triple XP-L and a bit of time, I’m planning to build something that bright in a Cypreus host. Not sure I’d trust a Roche F6 to handle that much heat though; it doesn’t have much thermal mass.
It’s not scary ’till it comes on in your pocket. Think of it as a light saber with a focus problem.
With the non-ramping UI, if the button gets mashed in a bag or your pocket and stays mashed it just steps down all the way to off and stays there.
Here is my F6.
Finally it is now the perfect flashlight for me, thanks to @comfychair who helped me a lot with driver, flashing and now with the idea to fill the hole with an 3mm LED that I’ve glued there:
Out of curiousity, what firmware / UI style are you using?
He's using this: http://75.65.123.78/ramp_v07/
Color mixing from the status LEDs works better with the little optical pickup trimmed off flush with the ID of the driver cavity. I used a tiny little ball-end diamond bit, that also leaves a good scuffed-up finish that acts as a diffuser.
@ToyKeeper
Yes, I am using that one with ramping and it is the perfect one because it also has short press for on/off and memory.
Okay, I was just wondering… because I didn’t quite finish tweaking the ramping UI before I got interrupted by a work trip, and I haven’t gotten back to it yet. It’s pretty close; just needs some fine tuning on the ramp curve.
The levels I used in that one linked up above are:
0,1,1,1,2,3,4,5,6,7,8,10,12,14,16,19,23,28,34,41,49,58,68,79,91,103,116,130,145,161,178,196,215,235,255
That pattern, odd as it may be, works surprisingly well - and really well on the SRK-DD boards using the inductor.
The pattern in that one increases each mode over the previous one by:
1 1 1 1 1 1 1 2 2 2 2 3 4 5 6 7 8 9 10 11 12 12 13 14 15 16 17 18 19 20 20
Thanks. I pulled in the changes you made, and included it as a preset in my version.
That ramp pattern you made is a quadratic or “x squared” shape. It’s much closer to visually-linear than the logarithmic pattern I was using, but spends a bit less time at the lowest levels.
The new version I just pushed has a few updates:
The default ramp now is 40 steps, uses fast PWM, uses PFM for smooth steps between PWM levels, and goes extremely low by abusing PWM=0. I’m measuring just 0.1 lumens with a Sanyo 20R at 4.18V. It can ramp to several levels under 5 lumens, yet still goes all the way up to 1800 lumens. However, this extra-low moon is extra-sensitive to voltage, so at 3.6V it’s virtually no different than “off”. And at that low a voltage, the stair-step pattern returns somewhat.
In any case, it should be a bit easier to configure now, goes much lower, shouldn’t have an audible hum if you enable fast PWM, and I’ve tested several predefined configs to make sure they work.
So are you saying the one from BG has more room in the driver compartment than the one from FT?
It’s worth mentioning that comfychair has been absent for about 4 months. You might not get a reply.
Well that’s a bummer. Maybe somebody else can answer?
I accidently crushed my roche f6 microswitch by tightening the brass ring way too tight. Does anyone know where i could buy or harvest a new switch to solder in?
Also, has anyine tried a dedome or xp-g2 on copper to get more throw from the f6?
phsinvent - sorry, cant' help bout the switch, but you may want to consider a whole driver replacement now. I just received my "Roche F6" from FastTech and got one labeled Convoy F6. The glass breaker won't thread in, and when I tried applying pressure to thread it on, the whole SS end cap popped out, and can't seem to securely get it back in and stay. I opened a support ticket with FT on it. Below are pics I included in the ticket.
Also, the way the modes work on mine (seems to be variations out there), is hold to turn on, click to change modes, hold longer to turn OFF. While on in any mode, double click will go into strobe with a click to return to normal mode. Weird - the light works with the end cap removed because the spring is held in by a ridge in the tailcap.
Now I dunno if the Roche OSHPark board I ordered will even fit... Have to check measurements... It's not bad stock though. Mode operation is decent, modes are well spaced. I measured:
On a fresh charged LG HE2: 1.92A tail, for lumens, Hi: 595 @start, 578 @30 secs, Med: 204, Lo: 54, throw: 4.8 kcd - 128 meters
Someone linked this earlier, but looks like BlackShadow is the OEM, but makes several brand names. Light is listed here: blackshadow.en.alibaba.com/StarryLight_SD01
