How do I figure out how long a light bulb will last?
By testing the light output every 1,000 hours for 6,000 – 10,000 hours, you can determine how much light will be lost (or fade away) over time. By connecting the light output “dots” at 1,000 hours, 2,000 hours, 3,000 hours, etc.
How do you know if a light bulb has gone?
how to tell if a light bulb is blown:
- it doesnt work in the light socket.

| Plug-in | 10,000-20,000 hours |
| Screw-based | 8,000-10,000 hours |

LEDs are the longest-lasting light bulbs, working for years longer than their counterparts. The average LED bulb lifespan is about 50,000 hours.
How long does an average LED bulb last?
Many LEDs have a rated life of up to 50,000 hours. This is approximately 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen, and 8-10 times longer than a typical CFL. Used 12 hours a day, a 50,000 bulb will last more than 11 years. Used 8 hours a day, it will last 17 years!
Are T12 lights being discontinued?
In effect since July 2012, the legislation eliminates nearly all 4-foot T12 lamps, some 4-foot T8 lamps, most 8-foot T12 lamps, and almost all standard halogen PAR38, PAR30 and PAR20 lamps from the market. T12 technology is over 80 years old. Since that time, lamps and bulbs have been developed that just work better.
