modern lamps should have a practically infinite shelf life. Certainly a good 20 or 30 years. As long as they aren’t stored in damp conditions, and aren’t physically abused or vibrated or shocked, there is nothing to go bad.
Do unused light bulbs expire?
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?
Typically, LED bulbs can last between 35,000 and 50,000 hours. This is over 17x more than the lifespan of an incandescent bulb!
|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.|
Do LED bulbs expire?
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!
How long do light bulbs typically last?
Typical incandescent bulbs last 1,000 to 2,000 hours. But in speaking about LED replacements, lamp life is routinely quoted as 25,000 to 50,000 hours.
Why do light bulbs go bad?
There are many possible reasons why a light bulb burns out quickly: The power supply voltage may be too high. Bulbs may be loose or connected improperly. Excessive vibrations may be causing the filament to break.
Do UV bulbs have a shelf life?
UV Bulbs are widely used in aquariums and florescent bulbs. According to General Electric the average UV light has an unlimited shelf life as long as it is kept in a dry, dark area at a moderate temperature.
Will leaving a light on cause a fire?

Why do my LED bulbs not last?
Though you may not know what is causing the problem, there are a couple of reasons why your LED lights keep burning out before their time. The most common reasons for LED blowing out are high voltage, bad contacts, use of incompatible dimmer switch, or recessed lighting.
Does LED light cause fading?
LEDs do not fade artwork when used within the specified luminosity and duration of time. Without infrared radiation or heat from the bulbs, it becomes a factor. Some yellow pigments used decades ago might be prone to turning green due to the blue light in LEDs.
What light bulb lasts the longest?
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 often do light bulbs need to be replaced?
As a general guideline, an MH bulb will reach that 50% light degradation mark in about 6 to 10 months, depending on how many hours per day it’s in use. An HPS bulb will last longer; the replacement time is every 10 to 14 months.
Which type of light bulb lasts longer before burning out?
Compact fluorescent (CFL) bulbs and LEDs (light-emitting diode) typically last much longer – about 10 thousand usage hours for CFLs and 25 thousand hours for LEDs.
