How much time Lexel do I have, to give you the numbers and details of what I want?

Basically I will ask people that had replied here as there is interest for at least 25 drivers, to give me a final number how many they take and send the payment instruction
When I have confirmation of people with the final number of drivers they take,
Then I will start ordering parts, and also as last time more for people who join in later

So if you tell me as early as possible a number you take for sure its better than a number higher than you take in the end

the 22mm Board fits up to 10mm base diameter springs

Ok, no spring on the 22mm. I have some be-cu springs I can cut down and bend a bit to fit.

I got some Be-Cu springs as well, dont need to be cut and bend, they simply fit
but as you solder the positive wire to the top of the spring there is no need for low resistance spring, you can use thin steel springs
The Be-Cu springs are not nearly as flexible as steel springs, first time compressed they get shorter

We got interest on 30 drivers

a lot more information needed on Narsil version, Temperature and configuration as well if you want springs

When I am ready with it I will send out payment instructions and will order boards and parts

Manual for Narsil v1.4
http://www.metronixlaser.de/bilder/flashlight/Narsil_Triple_Manual_v1-3.pdf

NarsilM got released, it is a bit different with temp. calibration in User settings
The only improvement I see in LVP for 2S lights, but it lost some setings to get the UI Settings easier

Ok we met the minimum number of driver to start ordering parts and boards
I will order from digikey this time later when the first Oshpark boards arrive, so the number of drivers is not limited by an early order from digikey parts

Priced for Bistro HD OTSM and NarsilM updated

Option for customized modespacing/modegroups added or you give mne a customized HEX file

For the lights 60-70°C for single LED should be OK

for Triples in small hosts it should be less as the head can get hot fast while the LED driver is relatively cold

Lights like the L6 with tailswitch can be set up to go in turbo when battery power is applied, or 2 low blinks or nothing at all
It might be also possible over the advanced setting interface to get the light come up at last memorized level

For the temperature setting I would like 50 C on both of mine along with the standard mode spacing. I like starting on low

Thank you.

I am trying to figure out how to get the code working to start at low, when the light gets powered on with tailswitch
I hope those settings can be achieved
tailswitch PO: moon (M) low (L) Turbo (T) 2 blinks (2B) mode memory (MM) no output (NO)

On last batch when people did not specify a temperature for protection I set 60°C, not too aggresive but also a temperature where Triples on a Host like Eagle Eye X6 does not overheat
Its a protection if the light gets turned on unattended, lowering the output of the light, not a temperature control keeping the light on that temperatue

50°C is quite low for temperature protection, my nitecore P12 gets to 60°C and it is still comfortable to hold on the tube
Lights with DTP star have no problem to survive over 70°C head temperature,
there should be enough time that a good portion of that heat gets to the driver, of course the driver will always stay a big cooler than the head if its not potted to the shelf of the emitters
so the longer the light needs to heat up the more heat the driver will get as well, so the temperature can be set high

on Convoy S2+ Triles that draw like 12-14A the head gets very fast very hot, while the driver is still on a moderate temperature, there I would go for 50-55°C
