This driver, designed by Alex Wells (wight), is a great option for a regulated 22mm driver.  With LED current options ranging from ~1A all the way up to 6A, you can easily dial in your LED current.

Because each driver is custom built to order, there is a 3-10 business day waiting period after ordering this driver.

As usual, there are plenty of different firmware options available! (See below)

Increase/Reduce Driver Current 7135 Option

By default, the 22mm 7135 driver comes with 16*380mA 7135 chips.  You can decrease the output current by removing 7135 chips, each chip removed subtracts around 380mA. 
 

Features:

*Input voltage: 2.8V - 4.5V

*Default Current: 6A (without removing any 7135 chips)

*Constant current

*PCB diameter: 22mm

*PCB thickness: 1.6mm

*Components height: 4.7mm

*Reverse polarity protection

*Gold plated contacts

*22 AWG Silicone+Teflon Leads Pre-Soldered

Spring / Contact Options

• No Spring or Contact Soldered
• QLITE Spring -  This short but stiff option works well for most lights.
• Copper Braided Spring - This is a taller and wider spring that has been copper braided to reduce electrical resistance.
• Brass Button - A short brass button to help raise the battery contact surface 2mm.  Low resistance but no spring action.  

FIRMWARE OPTIONS --- CLICKY SWITCH (Normal Rear Switch)

All 22mm 16x7135 Drivers now come with guppy3drv as the only option (attiny25 MCU)

guppy3drv is a very configurable firmware that offers a lot of advantages.
