Comparing LEDs to CFLs
HISTORY OF CFLs
• CFL = Compact Fluorescent Light
• Invented by Ed Hammer in 1976 (but shelved by General Electric)
• First real challenger to the incandescent bulb (~1995)
• Popular lighting choice to replace 100-year old incandescent technology as
a result of:
• energy efficiency/cost savings (uses 1/5 to 1/3 of electric power)
• superior lifetime (last 8-15x longer)

Are they still the best lighting technology choice today?
While CFLs do outperform a 100-year old technology, how do they compare
against newer lighting technologies, such as the Light Emitting Diode (LED)?
This presentation examines both CFLs and LEDs to see how they stack up
against one another.
Note: For all performance-related categories, the output of a standard 75-
watt incandescent bulb is used as a basis of comparison.

EFFICACY
March 2014
Comparing lumens per Watt (lm/W)
www.LeapfrogLighting.com
LAMP WATTS LUMENS EFFICACY
LED 12.5 1000 80 lm/Watt
CFL 20 1150 57.5 lm/W
Benefits
• Lower electricity bills
• Less greenhouse gases

LIFETIME
www.LeapfrogLighting.com
LAMP LIFETIME (HOURS) REPLACEMENT FREQUENCY
(40,000 HOURS)
LED 40,000 1
CFL 10,000 4
Benefits
• Fewer bulb replacements
• Less landfill
• Lifetime not shortened by power usage patterns
(see “On/off cycling effects”)
• Lifetime not shortened as a result of installation method
(for example, when a CFL is inserted upside down in a
hanging, enclosed fixture, the power supply heats up. As
a result of inadequate heat sinking capabilities, CFLs
tend to bake and die much faster than their published
lifetime).

ENVIRONMENT AND HUMAN
HEALTH
www.LeapfrogLighting.com
IMPACT LED CFL
Contains Mercury (toxic to both environment and
health)?
No Yes (~5mg)
RoHS-compliant (Restriction of Hazardous
Substances – directive in controlling the use of six
hazardous materials)?
Yes No
Carbon Dioxide Emissions (CO2 is the main
greenhouse gas)?*
4.4 kg/yr (1300lm
@ 2 hrs/day)
7.3 kg/yr (1300lm
@ 2 hrs/day)
Infrared or ultraviolet radiation emissions? Extremely low IR Yes
*source: http://www.green2light.com
Benefits
• Less environmental contamination
• Less personal exposure to hazardous material
• No degradation of artwork, furniture, carpets, etc.
March 2014
ROBUSTNESS
www.LeapfrogLighting.com
IMPACT LED CFL
Turns on instantly? Yes Delay
Light flicker? No Yes
Heat emitted? Very low (3btu’s/hr) Medium (30btu’s/hr)
Temperature sensitivity? Slight
Sensitive where unable to vent
excess heat, but much less sensitive
than CFLs
Yes
-Low/no in freezing temps
-Lifespan significantly shortened depending on
how bulb is installed (ie. Upside down or within
enclosure traps heat)
Durable? Yes Fragile
On/Off cycling effects? No Yes
March 2014
www.LeapfrogLighting.com
Benefits
• Immediate light (no wait period)
• No risk of triggering migraines or epilepsy attacks (no light flicker). NOTE: The relationship has been
contended, even though cases have been reported (see http://bit.ly/PTUA23 for more information).
• Minimal risk of fire
• Superior lamp performance in all weather conditions
• Less risk of breakage
• More dependable – lifetime unaffected by frequent use
March 2014
ENERGY CONSUMPTION
Benefits
• Reduced electricity bill
Comparing lumens per Watt (lm/W)
www.LeapfrogLighting.com
LAMP WATTS KWh/yr (@24 hours/day) COST/yr (@0.119/KWh)
LED 12.5 109.58 $13.04
CFL 20 175.32 $20.86
March 2014
www.LeapfrogLighting.comMarch 2014
The math is pretty simple: Less energy used  greater electricity savings
Return on investment is recovered quickly (from a few months to a couple of
years, depending on usage).
Note: While dimmable LEDs do cost slightly more than non-dimmable LEDs of
similar wattage, you can scale back the light to ~10% of its full output, thereby
reducing the amount of energy required.
There’s also a hidden savings: that which is achieved through cost avoidance.
A longer lamp lifespan means you don’t need to spend valuable time
performing maintenance tasks (for example, buying new bulbs or replacing
dead bulbs).

As a result of inadequate heat sinking capabilities, CFLs tend to bake and die much faster than their published lifetime). March 2014

  • 16. www.LeapfrogLighting.comMarch 2014 The math is pretty simple: Less energy used  greater electricity savings Return on investment is recovered quickly (from a few months to a couple of years, depending on usage). Note: While dimmable LEDs do cost slightly more than non-dimmable LEDs of similar wattage, you can scale back the light to ~10% of its full output, thereby reducing the amount of energy required. There’s also a hidden savings: that which is achieved through cost avoidance. A longer lamp lifespan means you don’t need to spend valuable time performing maintenance tasks (for example, buying new bulbs or replacing dead bulbs).
