Multiple drivers per emitter analysis

Flashlight Modding and DIY Parts

Hello!

Well, some hours ago a newb on forolinternas requested some advice with regards to building some sort of high battery life custom headlamp intended for spelunking.

Not gonna dive into the details about the colour temp of the 2 XM16 XM-L2 U4 1Cs emitters he had already bought, but I warned him that was a BAD decision for such an absolutely dark environment.

By the way:

Onto what matters, since he wanted efficiency/range, I proposed him the use of two different drivers per emitter. That way, if I am not mistaken, a combination of three levels of light output efficiency could be achieved. Linked him to Simon's store for the drivers, and my example proposal was to use 2 different Nanjg units/each:

  1. A 3×AMC7135 so 1.05A non-PWM plus derived available PWMies and disco stuff.
  2. A 6×AMC7135 so 2.1A non-PWM plus derived available PWMies and disco stuff.
  3. 1 + 2 = 9×AMC7135, thus 3.15A combined high mode plus all of the combined PWM and non-PWM-messes and strobes.
  4. A classic reverse clicky to feed each driver.

Sounds good?

I post this just to share the concept, I really doubt he's going to take the route, yet this seemed a nice idea for setups which could afford to have multiple ON/OFF switches and driver boards.

Cheers ^:)

I have considered multiple custom drivers for modding lights that have two e-switches. Such as some sunwayman and nitecore flashlights. My purpose was aimed toward controlling multiple emitters though. Probably 2 white and one red in a triple setup. Anyway, I never moved forward after the initial thought. But it’s still not off the table:)

Be simpler to use an LD-02 driver.

Or a triple channel with 3 banks of Amcs. It can give a number of pure constant current modes.

Just buy a simmple CC driver
