If a light bulb is off; how can you tell that It has been used recently? ANSWER ASAP

If you have a second fixture around, you can use the same test of putting a tube in a working socket and see if it lights. It is not uncommon in fluorescent fixtures to have the ballast burn out. You may detect a burnt smell or see the bulbs flickering.

Touch the bulb, if it is hot then it has been used recently if it's cold then it hasn't been used recently.
