The Shelf Life of CFL (Compact Fluorescent Lamp) Light Bulbs
CFLs typically have a rated service lifespan of 6000–15,000 hours , whereas standard incandescent lamps have a service lifespan, of 750 or 1000 hours.
How do you know when a fluorescent bulb is bad?
- Check the ends of the tube. If they appear darkened this indicates the bulb is burned out.
- Rotate the tube in the fixture if the bulb is not darkened on either end.
- Remove the bulb from the fixture if the bulb is still not illuminating.
Do fluorescent light bulbs expire?
Fluorescent bulbs can go for years without replacement —even when the ends start to blacken. Don’t worry about them until the light they put out starts to weaken.
How many years does a fluorescent bulb last?
LED tubes last an average of 50,000 hours (roughly 16 years) while fluorescent T8 tubes last an average of 25,000 (roughly 8 years) .
Can unused fluorescent bulbs go bad?

Do car bulbs have a shelf life?
Registered. Light bulbs do not expire , they do have an average expected lifetime in hours used. They are safe to use untill the filament breaks and should have the same brightness as a new bulb.
How long can a light bulb stay on safely?
| Type of Bulb Average Lifespan When should you turn it off? | LED 35,000 – 50,000 hours Can be left on 24/7 | Incandescent 750 – 2,000 hours Turn off when not needed. |

How often should fluorescent bulbs be changed?
Typical lamp life for a fluorescent bulb is about 20,000 hours , but this can degrade as a consequence of frequent switching (turning on and off). Burning life is extended if lamps remain on continuously for long periods of time.
Do both fluorescent bulbs need to be replaced?

Why do fluorescent bulbs burn out quickly?

The diode itself will begin to emit less and less light as the years pass. Still, LED lamps can last over 25,000 hours .
Why do light bulbs go bad?
