Almost all light bulbs can stay on for at least 40 hours straight. :)

It depends on the type of light bulb and its wattage. Typically, LED bulbs can last up to 25,000 hours or more, while incandescent bulbs last around 1,000 hours. It's recommended to turn off lights when not in use to prolong their lifespan.
