Cave Johnson here, ever try to throw a torch? me neither. You know why? it lights things on fire. Things we don't want on fire, like expensive lab equipment instead of test subjects. That's why the boys down at the lab came up with this, the brand new Aperture Science Flameless Light And Radiation Emission Gun, or F.L.A.R.E. GUN. Just give it a steady supply of adhesive(Sticky Resin), then fire harmless light emitting devices at any range. Of course, they fall apart if you try to remove them, but who needs renewable light sources with technology like this at your fingertips? Use it to light caverns from afar, prevent monsters from falling on you, or make glowing graffiti of your favorite company logo! Cave Johnson, we're done here.
you sir are a genius, seriously your rank should be "awesome aperture science rep". UUM to you
