Modifying laser to have white LED light.

Crimson Trace LG-431:
Battery:
Manufacturer Recommended:
1x 1/3N Lithium (3V, 11.6x10.8mm)
Or 2x 357 (SR44) Silver Oxide Battery (3V total, 11.6x5.4mm)
Possible alternatives to alter available voltage:
SR54: 11.6x3.1, 1.55V (4.65V Max)
SR55: 11.6x2.1, 1.55V (7.75V Max)
365/366,S16,608: 11.6x1.65, 1.55v (9.3V Max)

The sky is the limit for available voltage, but the device components have voltage and current limits.

Laser:
Output: ~5mW
Wavelength: ~650nM
Operating Voltage: Unknown, need to check.
Constant Voltage Driver: Unknown, need to check.

Switch:
Pressure Operated, connected to Laser housing via PCB ribbon. Not amenable to modification outside of housing.

I have one V=IR'y good reason to take caution with this project...

You do realize that laser probably draws around 20ma max? And at 3v you'll get a keychain LED levels of light output. Stop being a poorfag and just buy a Surefire.

Tape small pen light to laser.

Keychain LED levels of light is the target for this modification. This isn't intended to be blindingly bright, but instead to provide a usable amount of illumination for target identification. A separate light would be a superior option, but the objective is to integrate it into the laser module for convenience sake (e.g. one-handed operation).

Believe me, I looked into that. The main issues are holster compatibility and switch actuation; the LG-431 has good aftermarket holster support and already has an intuitive, ergonomic, automatic pressure switch.

There are companies that make good lights and good lasers for the LCP, but not that have both functions. This would add a weak LED to the LG-431 without adding any extra bulk and only adding a few grams (max) of weight.

It wont unless your target is 3 inches away from you. You could have gotten the same result by putting a diffuser over the lens.

Surefires have pressure switches too

>aftermarket holster support
You do realize that you can have holsters custom made?

>LCP
At the ranges you're using this gun you'll never need a light or laser. Practice on point shooting because thats what you'll end up doing.

Why would you pay the surefire premium when nitecore exists?
