75,000 watt, 2.4 million lumens incandescent light bulb!

Oh, c’mon. I got a 3AAA tulip-head zommie that can do at least 2.4M lemons.

It said so right in the ad.

Mmm...

Millions of lemons!

Thats a good point, isn’t the record from a Chinese flashlight something like 99 billion lumens.

@Bort

isn't the record from a Chinese flashlight something like 99 billion lumens.

I'm waiting for a flashlight that promises infinity lumens.

Five minutes later, there will be a flashlight promising infinity plus one lumens.

Gotta have that plus one!

Having spoken of Edison, please do not forget Nicola Tesla, who (IMHO) beats Edison in every field.

If it was a single LED it would be amazing, an array just isn’t as cool.

But GE was cheating too, they used a quad filament

[hron61]

Would make for one hell of a mule!!

Fair enough, lol.

It’s not 75k but 20k watts. “It doesn’t have a filament, it has garage door springs”

Now for the big question…WHAT WOULD THIS TRANSLATE TO IN CHINESE LUMENS???

2,400,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,00.2 lumens!!!

[wle]

it may have never been powered

i mean to REQUIRE that many watts, just means you make a big fat honking filament, which it has

the plaque doesn;t say it has ever been used….

and it may not be intended for 120VAC, which would cut the amps

it has 4 filaments and 2 connections, if it had 3 and 3, it could run on 3phase power
but of course EDISON would not have any of that
he was a DC man

The vintage in-situ photo others have posted have a sign which lists lighting times! Probably wouldn’t get away with that nowadays, damn ’elf n safety :sunglasses:

I’d take the infinity lumens since it would sell for 1/10th the price.
This is Budget light forum after all

==oh
huh
so it does

does not show the wires going to it

would like to see

oh well

They probably ran it on 240? It needs really high current to start, but that drops off as the filament heats.

[wle]

312A to run at 240
edison may have designed it to run directly off some crazy generator just for that
though the DC generators usually are not very high

would need to be 750 V to make it 100A
that might have worked

[Rusty_Joe]

Infinity x 2.4 lumens!

[Westie]

BLF: Yeah but is it high CRI? I don’t want it if it’s over 5000k. How’s the tint?

[Lightbringer]

I heard they made the base a left-hand thread, so no one could steal it and use it at home.

[RobertB]

That bulb was definitely used. You can see the frame darkened at the top, and the glass as well.

[Firelight2]

The bulb was powered on.

This link from Cleveland Historical includes a photo taken in 1954 showing it powered up. It’s obviously not running at full power though. Or their definition of “75,000” watts isn’t what I’d expect.
