What is electrons? How do you convert them to light? Doesn't this make the flashlight lighter?

Yeah, pretty much.

No, they don't weigh less. The electrons flow through the battery, none are "eaten up" by the lightbulb. Energized electrons move into higher energy states. This is called an excited state. It is not stable, and the electrons will eventually move back down to their lowest energy states (except in some cases, such as phosphorescence). This move creates an electromagnetic disturbance we call "light". This light has energy equal to the energy released by the electron moving, which is equal to the energy it took to move the electron to an excited state. This energy comes from the potential difference on either side of the batteries, which causes electrons to move. When they move through a resistant filament in the bulb, they heat up the filament, causing the atoms to become excited. The voltage of the battery is created because of chemicals of opposite charge in each side of the battery. One of these chemicals has free electrons, the other can receive them. In rechargeable batteries, the chemical reaction between the battery fluid and the terminals attached to the wire can be reversed by adding energy to the system.
That's how flashlights work.
tl;dr no mass is displaced because there are the same amount of electrons in the flashlight at any given time, and light has no mass. The energy required to make light was already present in the battery.

Hey man, he could be serious, give him a break.

No, photons are said to have zero mass.
Samuel Peterson
the electrons go through a potential energy change, this is the energy used to make the light.
But the electrons themselves just end up in lower energy state in another chemical on the battery. They literally flow from the neg to pos nodes.
Dylan Jones
Electron theory is nothing but a complete bullshit. Here is the correct answer.
As an empty space filled with air molecules, the vacuum filled with luminiferous aether. As you know, when you heating up an object, its atoms start moving faster. That oscillation is realy like a pulled string that pushed aether and create waves.
Elijah Bennett
potential energy manifests itself as inertial mass
Colton Kelly
they have zero 'rest mass'
