In terms of led vs cfl in energy efficiency both cfl and led bulbs are good for conserving energy with led conserving a bit more.
Led cfl light bulb comparison.
Led bulbs are more energy efficient than cfls.
Bulbs needed for 25 000 hours of use.
Light bulb projected lifespan.
Fluorescent bulbs are generally less expensive than led options but they have a shorter lifespan and must be carefully recycled due to their mercury content.
Watts per bulb equiv.
Compared to traditional incandescents energy efficient lightbulbs such as halogen incandescents compact fluorescent lamps cfls and light emitting diodes leds have the following advantages.
Cfl bulbs are cheaper than led bulbs but they cannot be dimmed and it may take some time after switching them on for them to become fully bright.
Similarly cfl bulbs may not turn on or reach full brightness in very cold climates making them less suitab.
The primary difference between them is led bulbs are durable and long lasting as compared to the cfls.
Other replacement lightbulb choices consume more power than led bulbs and have shorter rated lifespans but cost much less upfront.
Equivalent 25 000 hours bulb expense.
Fluorescent bulbs vs led bulbs comparison.
Unlike incandescent compact fluorescent cfl and halogen bulbs which have a very wide beam range leds have a narrower lighting angle and are thus best suited as spotlights.
The life of a led bulb is usually up to 50000 hours or more while the life of a cfl bulb is up to 8000 hours.
A lumen is the measure of the brightness generated by a light as seen by the human eye.
How to understand this table look at the lumens brightness in the far left column then compare how many watts of power each light bulb type requires to produce that level of brightness.
Cfl and halogen bulbs.
The inherent design of leds makes it give off directional light.
The led bulb consumes less electricity than its counterpart cfl 75 a year in energy cost.
Kwh of electricity used over 25 000 hours.
The led bulb stands for light emitting diode and cfl stands for compact fluorescent light.
Cost of electricity 0 10 per kwh 21 25.
While the math for the cfl bulbs is simple the led bulbs are even more energy efficient and durable than compact fluorescent light bulbs.
Typically use about 25 80 less energy than traditional incandescents saving you money.
Led bulbs require much less wattage than cfl or incandescent light bulbs which is why leds are more energy efficient and longer lasting than their competitors.
