How much vacuum inside a fluorescent lamp? « on: September 19, 2021, 11:08:04 AM » Author: LightUpMyLife
One of my YouTube subscriptions justs did a new science experiment where he breaks open some fluorescent lamps to show how much vacuum is inside them. He breaks open a 4 foot and 8 foot tube underwater to show how much they fill up.

They are typically filled to around 3-5 torr, so about 99.5% vacuum
