“I used to think that top environmental problems were biodiversity loss, ecosystem collapse and climate change. I thought that thirty years of good science could address these problems. I was wrong. The top environmental problems are selfishness, greed and apathy, and to deal with these we need a cultural and spiritual transformation. And we scientists don’t know how to do that.” (Gus Speth)

Very nice!

If I were to swap the current driver of the Q8 to one of these Lexel drivers, what would I gain?

Keep dreaming.
Super saiyan powers.
sigh……. i wanted god powers
Don't give up on your dreams,
Keep dreaming.
What is the advantage of the BLF GigaThrower Treiber XHP70.2 or Oslon Black Flat up to 8A over a modified GT driver with resistor mod?
What we really need are DTP copper MCPCB’s in XHP-70.2 format!
The Buck driver would support XHP35s, but also the tail board has to be modded to a fixed position as well the tube secured on the head
The Q8 driver is good, it is still possible to get the one with 16AMCs for regulated output up to 5.6A, the MOSFET I use is a bit better than the original, but mst gain comes from taul spring bypass

Nice lexel.. you are adding more new driver..
Can you guys tell me estimate lumen and lux for thr blf gt? Xhp70.2 and oslon black .. jason, we need you!
Excellent work Lexel.
My current and or voltage measurements are only relevent to anything that I measure.

Hi Lexel, do you have any Eta on the 22mm buck driver?
I will order first prototype boards this weekend
I make them 4 layer for better heat dissipation, but this also makes the order in china expensive and I just odered a bunch of 4 layer 2 weeks ago, so I need to fill the 10×10cm with more boards before i do a new order

How many Lumen/Kcd can we expect for L2 with XPL hi with 1/2 LK50 ?
That Buck driver is targeted to drive XHP50.2 basically in that light
for throw you will have to wait for the Boost driver for XHP35 at 2-2.5A
this Buck should do fine up to 7A output but is limited to 2S input

Nice one Lexel,
how much are the buck drivers for the L2 / Xhp50.2 ??
Can Bistro be used with these drivers?
sure it is designed on Attiny25/85 based footprints

Looking forward to the 20mm/22mm buck drivers. I got Jaxman Z1 and a Convoy L2 that could use the drivers.

Outstanding! Way to GO Lexel!
KB1428 “Live Life WOT”
Supported firmware?
Price?
And where can I buy them?
I second this request
Firmware as usual NarsilM v1.2 Gigathrower
ramping to 100% also possible
Bistro HD OTSM I have to look into to modify the firmware to have right modes
Prices:
for the Buck 20 and 22mm will be 17.5€
for the 17, 20-22, 23mm and 24-30mm Boost I have to calculate when they are fully tested, but parts costs about 5€ more than the LM3409 buck
for CFT-90 drivers 75-80€ depending on additional current and high current parts
this is not a cheap one just the parts cost more than 35€
