To some of us, this is a relatively new debate. Some people are even shocked that they won't be able to purchase replacements--so shocked that they are stockpiling light bulbs.
However, this light bulb war began almost as soon as the incandescent bulb was invented in the late 1800s. Thomas Edison's revolutionary carbon-filament light inspired many others to try improving the bulb or find alternatives. One such person was Nikola Tesla.
Whichever side of the war you, your parents, your grandparents, your great-grandparents or their parents were on, there is no denying the genius of Thomas Edison and the fact that he changed the world forever with the bulb that truly made him look like the "Wizard of Menlo Park."
The light bulb war was fully underway in 1896. In the following newspaper article, Thomas Edison defends the energy efficiency of his incandescent bulb while Nikola Tesla touts the efficiency and superior light of his phosphorescent lighting. D. McFarlan Moore also weighs in with his gas-discharge based lighting.

ELECTRIC LIGHTS.

There are many indications that we are soon to have electric lights so cheap that anybody can afford them. At least this is the promise of three noted electricians who have been working on the problem for some time past. The fact that Thomas A. Edison and Nikola Tesla are two of the three referred to gives strong assurance that we may look for a revolution in our system of illumination in the near future.
A writer in the Washington Star has had an interview with Edison from which the following is taken:

"I started out with ten incandescent lamps per horse power," said the wizard, "and after a while succeeded in bringing these up to such a state of perfection as to string fifteen of them on a line for each horse power employed. Now I have practically succeeded in improving my incandescent lamps so that I can put twenty lamps where I could only put fifteen before."
"Then you are not experimenting with etheric or phosphorescent lighting," I said.

"Would you care to state just how you have improved your new lamp?"
"Not just yet. I have still some finishing touches to make on it. You see, when Prof. Roentgen made his wonderful discovery of the X rays, I dropped everything in order to repeat the experiments here. These rays open up wonderful possibilities in the electrical world, and may make it necessary for us to completely reconstruct the undulatory theory of light. Just think where we are now! Photographing through wood and metal, talking by telephone a thousand miles away, telegraphing under the ocean, despite of storms and tempest--why, one of these days we shall perhaps see by electricity."
"You will keep your carbon filament in the improved incandescent lamp and not dispense with it, as Tesla proposes to do?" I asked.

"Then you think your latest improvement will cheapen electric lighting?" I asked again.
"I don't see how it can help it," replied Mr. Edison. "If I can run twenty lamps where I now use fifteen, don't you see that there will be a considerable saving?"
"Have you taken out your patents yet?"
"No--nor shall I. I don't believe in getting things patented any more. It doesn't protect you. The only safe way is to keep the secret yourself as far as possible."
I had a pleasant chat with Nikola Tesla the other day, and learned from him that he has about perfected his new phosphorescent light, which will come as near artificial daylight as anything yet attempted. There will be no filament in the glass bulb; nevertheless it will glow with all the brilliancy of an arc light. The current employed will be of low voltage, but it will be changed into one of high potential by induction coils. In this way three improvements will be erected over the present incandescent lamps--brighter illumination, no deadly wires and cheaper cost.

The third electrician who is grappling with the problem of cheap illumination is D. McFarlan Moore, who claims to have solved the secret of the fire fly. Following close upon the heels of Roentgen's rays, the discovery promises to work a revolution in electric illumination and foreshadows an era of one unbroken day.
There are no hairpin filaments in Mr. Moore's system, as with the incandescent lamp, and the illuminating agent is disturbed through water and gas.

Mr. Moore's new light, owing to the absence of heat, requires little power to generate it, and can be produced from a battery the size of that which rings the front door bell. In other words, an ordinary glass jar, containing pieces of zinc and carbon immersed in acid,

Mr. Moore's apparatus is not much bigger than an ordinary size teacup, and the little machine that breaks the circuit and corresponds to the electric bell is not bigger than one's finger.
