Laser drop-in?

[Sgt. LED]

Has anyone ever heard of such a thing or think they could make one?
Does anyone think they would sell well if made available?

Tossing a green laser into a flashlight body when desired would be really cool! What's the runtime on an 18650?

Good idea.
Maybe this in a drop in 5mW Green Laser Module (5V) .
Not sure of the size, it looks small enough.

What's the runtime on an 18650?

Wow, that boggles the mind. Laser pointer, ~0.001 Watts, 2600 hours runtime. Balloon-popping laser ~0.125 watts, 21 hours runtime. Or are my calculations flawed, I am assuming output power from the laser, and ignoring the inefficiency of a diode laser (which should actually be pretty efficient, right?)?
