For another rifle, I got the kit off ebay of Perst 3 Green +, Klesch-2 dual band light, and the KV-4/2U dual control switch. The switch just arrived, because they forgot it originally so I have used the light and laser, only just started playing with the switch.
Went with this setup to get a bright white light. If they had a dual band bright white light in the Perst 4 I'd have done that. Also, this is still cheaper!
They include several spare mounting bits, and their weird picatinny canteliever ended up being very useful for my strange gun. Photo with wires and switches not in final position:
White light is as bright and clean as any other bright lights I have, but seems a bit dimmer as it's a much wider beam. Feels on par with the 500 lumen X300s at the target, but lights up the whole back yard, not just 25% at a time.
IR illum is similar: crazy bright, and very wide spread. This is a CQB or nearby surveillance light, not for illuminating targets hundreds of yards away.
The dual switch has:
- A rotary dial up top with three positions. Left, right, both. Left and right control whatever you plugged into them. Same controls, same plug, your choice.
- Button works as usual for remotes. Power dial works as usual just can be for whichever or both.
- Lockout cross-bolt at bottom is weird. Turns off everything, and also locks out ALL the light controls even on the light itself. It doesn't lock out the on-laser controls. Fine, but weirdly inconsistent.
- Button is a little too small for me. Too fussy a control set so hard to find, I might rely on the lockout and add a big protruding button (adhesive rubber bumper, etc) to make sure I can push it when I want.

This is set to lockout, and controlling the left hand device. Up is both. There are icons but they aren't meaningful until you already know what they mean.
