5 Myths About LED Lighting

by Michelle S. on February 21, 2014

What makes LED lamps different from their fluorescent and incandescent cousins? Just how efficient are they? Here we separate fact from fiction to reveal five common myths surrounding LED illumination.

Myth #1: LEDs Don’t Produce Heat
LED light sources actually do produce radiant heat, although dramatically less than conventional incandescent lamps. Proper thermal management is required to achieve optimum efficiency and intensity.

Myth #2: LEDs Aren’t Worth the Cost Over Incandescents
With the 2,000 hour lifespan of incandescent lamps versus the lifespan of LEDs – which easily reaches the 30,000 hour mark – LEDs are the very clear winners.

Myth #3: Fluorescent Is As Good As LED Lighting
Every fluorescent lamp contains highly poisonous mercury, so if the lamp breaks the surrounding environment will be exposed. Linear fluorescents have a maximum lifespan of 20,000 hours – 10,000 less than the lower-end expectancy for LEDs.

Myth #4: LED Life Spans Can Reach Over 100,000 Hours
Only in perfect laboratory conditions. However, if designed properly, LEDs will work for decades without catastrophic failure. The lifespan of the LED depends on thermal management of the lamp system.

Myth #5: LED Lamps Are Hard on the Eyes
Properly designed LED lamps are fully dimmable, and easy to adjust for users who find their brightness too harsh. LED lamps without dimming capabilities may have a shortened lifespan.
