Rodburner. That sounds like a great solution for your intended application. Very fast and very capable. In this case it’s a light. My thinking is you want a great degree of control over a light. You don’t want it to turn before you need it. A light can very easily give away your position.
The laser saddle doesn’t “have” to be turned on if you don’t need it. I need my glasses to see clearly and fumbling around for them when somebody is kicking in my front door doesn’t cut it.lol I’m sure one of the smarter guys here can tell you how to sight in a laser, but in my case, it was dead on from the factory for any and all shots inside my house. And I won’t give a hoot if they see my position due to the laser, because if they see it, that means I’ve seen them and it’s over. That’s the beauty of this thing. No squaring up on a target, no sighting down the barrel or lining up sights. If the dot swings across their chest, lead surely follows..lol I’m standing in the fire position, finger on the trigger in this pic. This is all they’re gonna get of me..
Just throwing it out there. 
If an invasion is ongoing, I would quietly rack a round into the chamber while I sat in the dark looking over the tritium. Some perp creeping into the "target zone" may only be using a cell phone "torch" to light his/her way but that would be enough to determine if they were armed or not. If armed, the element of surprise is on my side and is fully protected by Castle Doctrine. A very bright white light, perhaps pulsing, would be deployed with a firm order to "GET ON THE f****g GROUND, NOW!!!" command. Ideally, the white light would be in situ while I moved away from it back into the shadows. As mentioned, a laser (or gun mounted flashlight) will, by default, point back at you.
