Would that also happen in a vacuum or does the spark need a medium in order to jump?

You won't have that luminescent arcing, just cathode rays.

A lightbulb has a glowing wire, not a jumping spark. Dumbass.

You could also generate electron positron pairs with a high enough energy and use those to conduct.

OP here. So a spark in a vacuum is possible, it would just look different?

Also, the EPA, Home Depot, and even flippin' General Electric refer to CFLs as light bulbs.

To be a bulb, it needs to be bulb-shaped.

>> No.5006534

>>5006513
It doesn't. It requires that reasonable people understand your intent when you use the term. Given that major producers, retailers, and therefore users of 'light bulbs' include CFLs under that heading, CFLs are light bulbs.
