Need help with an S2+ build

Flashlight Modding and DIY Parts
1

Hey all! I’m hoping you can help me out. This is my first time building a light and I can’t figure this out.

I was thinking of using the Lume1 FW3X mcpcb w/rgb aux lights and FFL350RD 3500k emitters. What 17mm driver should go along with this? I’d prefer something that can run Anduril 2. But it’s not a requirement. However, something that will utilize the rgb aux is a requirement.

If that’s not doable, what’s a better suggestion for 3 of those emitters?

What ya got?

Thanks for any help you can offer!

You can’t run Anduril on a S2+. The S2+ uses a mechanical switch and Anduril requires an e-switch.
Also you cannot run Aux on a mechanical switch light.

You could use secondaries with a Dragon Driver(Link) but it would be single color not RGB.

I’m not completely sold on the S2+. It just seemed the easiest to get. Is there a better Host?

If you want Aux and/or Anduril you’ll need a host with and e-switch and a driver that fits it and has RGB Aux capabilities.
Also if you still plan to use the FW3 MCPCB and Aux pcb it will also have to be compatible with a 20mm triple configuration.

I don’t know of any stock hosts that are setup for this.

For us mere mortals we can get ramping by flashing Crescendo firmware onto this driver

Some Maeerxu flashlights use drivers with rear mechanical on/off switches and fancy aux light functions. (But no aux lights on when the flashlight is turned off.) The UI is quite complex. other Archives - maeerxu

I haven’t measured the pill/ driver size in mine, but it’s bigger than an S2+ AFAIK.

I ended up buying the dragon driver and mcpcb with aux from CWF since I know they will work together and they will slide right into an S2+.

Next build I’ll dig a little more into it and dive a little bit deeper.

You’ll need a spacer if you don’t already have one:

If you plan to use an illuminated tailcap you’ll need to add a bleeder resistor to the driver.
The Dragon Driver has the pads for one.
I recommend a 470-475Ohm Resistor.

Yep. Got one coming

I did plan on that. Thanks for the heads up. Where would I go about getting that resistor?

If i remember correctly it takes a 0805 resistor.
They have them all over aliexpress or if you are in the US digikey.com is a faster option:
