I sure hope these will be available for purchase some day, this is amazing. Great job.
Here’s my money… please take it from me for several drivers! :bigsmile:
OK, I am interested 
but, it would really be nice to have –8.4V input
I would be really happy to have a 2-cell version of this driver.
Sounds great. Hoping you branch out to a 2S version.
Very nice! I am looking forward to this driver.
You should sell this driver through Mountain Electronics. I’ll buy several.
I want one! How much? PayPal ready! :heart_eyes:
Very cool.

It’s a near perfect driver but since I’m not from USA and wonder how much does it cost to get one if you are willing to send it to my country.
…and the BLF custom driver parade marches on.
Pilotptk explained it and I’ll take his word for it. LEDs are also more efficient at lower currents and pwm is high current, high frequency. Low modes are simulations of low current output but with high Vf issues. 100 % of 1.5A is more efficient than 50% of 3A.
Definitely interested in a couple of these if you offer them for sale here.
Plus it’s less stressful on the LED
interesting.
Everything is the most awesome thing ever, sorry to have rained on anyone's parade.
Low modes are simulations of low current output but with high Vf issues.
I don’t want to fan any flames here but I don’t understand this statement. Can someone put it in layman’s terms for me?
20% with a 5A output driver using PWM will do 5 amps for 20% of the time, and 0 amps for 80% of the time. The Vf required to get 5 amps through a XML2 is 3.75-3.80A. Tailcap amps will be a measure the average current, around 1A.
But, a non-PWM constant 1 amp into the same LED only needs an output voltage of 3.05-3.10 volts.
How preliminary is this preliminary? 2 weeks off or 2 months?
Do you have an approximate price range?
Can you expand on how the user can change the modes? IE programmed through the switches or through hardware programmer like the Atmel chips?
BTW: SOOO COOOL! :-D Looking forward to seeing more of these. A lot more!
