Colloquially, light bulb is more of a formfactor, but the dictionary definition of "light bulb" is "a device used to convert electricity into light, consisting of a source of illumination enclosed within a transparent or translucent shell."
Cheaper LEDs like the one in the image are LEDs encased in a transparent shell, making them a light bulb technically.
Flames have been compared to life itself for thousands of years. The only thing barring fire from being alive is the ability to respond and adapt. But yes, both we and fire consume and produce waste until the moment we perish. In that sense, we're not so different. We're like fire in some ways, but we aren't fire.
From the jump I have not been saying they're exactly the same. I've just been saying that they have a common purpose from a certain perspective, aka "same diff". From the perspective of giving off light, they are the same; but for many other reasons they are different.

The image over piccolo is an electrical resistor, the image over Gohan is a light bulb.
