Pro Tip

LED lifespan is affected by heat and power fluctuations. Using quality fixtures with good ventilation can extend bulb life by up to 30%.

Understanding LED Lifespan Ratings

LED manufacturers rate bulb lifespan in hours - typically ranging from 15,000 to 50,000 hours. But what does that actually mean in years? It depends entirely on how often you use them.

LED Quality Tiers Explained

Quality TierRated HoursAt 5 hrs/dayTypical Price

Standard25,000 hrs~13 years$5-10
Quality35,000 hrs~19 years$10-15
Premium50,000 hrs~27 years$15-25

Factors That Affect LED Lifespan

Heat Management

Enclosed fixtures trap heat and can reduce lifespan by 25-50%. Use "enclosed fixture rated" LEDs when needed.

Voltage Fluctuations

Power surges damage LED drivers. Consider surge protectors for valuable lighting investments.

On/Off Cycling

Unlike CFLs, LEDs handle frequent switching well. This has minimal impact on lifespan.

Dimmer Compatibility

Using non-compatible dimmers causes flickering and premature failure. Always check compatibility.

LED vs Other Bulb Lifespans

  1. LED: 15,000-50,000 hours

    The longest-lasting option. Up to 25x longer than incandescent bulbs.

  2. 2

    CFL: 8,000-15,000 hours

    Decent lifespan but contains mercury and takes time to warm up.

  3. 3

    Halogen: 2,000-4,000 hours

    Short lifespan and runs extremely hot. Being phased out in many regions.

  4. 4

    Incandescent: 750-2,000 hours

    The shortest lifespan. 90% of energy wasted as heat.
