50,000 Watt incandescent light bulb!!!
|
Now that's a BIG incandescent!
My parents went on vacation to the New England area...and went to a museum and saw this lightbulb and thought of me and took a pic to send to me! Now I am sharing this all to you! Enjoy!

@gailgrove a 100w 750-1000 hour bulb emits about 1600-1750 lumens. Remember the efficency increases with wattage. I seem to remember this bulb getting 20-25 lumens per watt so that could be up to 1,250,000 lumens!
this has to have a Special Fixture i bet....its such a Fire Hazzard if it were to be used improperly....and since it requires such high amperage no way you could run this thing at a typical house with 200 Amp Service.

If this needed 420 amps then the wire size would be 350 if using a 75 degrees wire rated type THHN copper.
But when say the wire numbers...if you said "I want # 4 wire" that means you refer to 4 AWG....but if you say "I want 4 "aught" wire" that means you are refering to 4/0!
I have read that, In 1954, the largest light bulb, rated at 75000 watts, was lit at the Rockefeller Center in New York, to commemorate the 75th anniversary of Edison’s first light bulb. The huge bulb was 3-1/2 ft high and about 2 ft in diameter. From high above, it illuminated the entire skating rink. It was allowed to cool for five minutes after burning for three minutes. In Jan 1879, at his laboratory in Menlo Park, NJ, Edison had built his first high resistance, incandescent electric light, though its thin platinum filament in a glass vacuum bulb burned for only a few short hours. He then tested thousands of substances before coming up with a more useful carbon filament which he presented in a public demonstration of his light bulb on 31 Dec 1879.

Question is: Why they made it for 115v instead of higher voltage?
