Efficiency of led vs.
Comparison of incandescent and led light bulbs.
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.
Since most household bulbs are 40w 60w 75w or 100w you may be able to memorize their equivalent lumens.
While the math for the cfl bulbs is simple the led bulbs are even more energy efficient and durable than compact fluorescent light bulbs.
Led bulbs last longer than traditional incandescent bulbs.
Incandescent lights similar to led do not generally flicker and or cycle on and off as the bulb reaches the end of its useful life.
Some of the common wattages vs.
40w equals 450 lumens 60w equals 800 lumens 75w equals 1100 lumens and 100w equals 1600 lumens.
Examine the label of the led bulbs at the store.
Lumens for incandescent bulbs are.
The department of energy reports that a 60w incandescent bulb will last for approximately 1 000 hours.
Leds on the other hand are energy efficient light bulbs that consume 25 to 80.
When electricity flows through the filament it is heated to over 2 200 degrees.
For example a correct replacement for a 60w incandescent bulb would be a 15 watt cfl bulb 60 1 4 15.
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.
You can expect a similarly bright 12w led bulb to last around 25 000 hours.
Rather incandescent light again like leds tends to emit less light prior to total failure at the end of its useful life.
