The laser example doesn't even make sense given that it, well, is light speed.
When lasers are called light, they aren't referring to it glowing or being bright, all a laser is is the amplification of light by means of emission of radiation, and then that light is projected outward on the course of the laser. It's actual light made of photons, a chemical laser just refers to the method used to power this.
Beyond this, using the 10th and 15th definitions is beyond nitpicking. Dictionaries are literally ordered in order of how common they're used. So the entire basis of this thread is to take one of the least used definitions of a word to try and change a standard, and then the example used to support this is outright incorrect, as it assumes, with no evidence or explanation, that chemical lasers suddenly aren't actually shining light.
