However wattage simply represents the amount of energy needed to use the bulb.
Fluorescent light bulb wattage comparison.
Ge high output rapid start recessed double contact 55 watt 48 in recessed double contact t12 4100 k cool white fluorescent light bulb item 1484974 model 10559.
Of course not every fluorescent incandescent metal halide etc lamp will give its lumens.
The annual energy cost of an led using a lighting control is 11 28 compared to 27 83 for.
The greater the lumens the brighter or more intense the light.
Lumens not watts tell you how bright a light bulb is no matter the type of bulb.
Through the increased use of fluorescent and led bulbs we use less watts to produce the same amount of lumens saving us money on energy bills.
To save the most money on your electric bills replace your bulbs with the lowest wattage for the desired lumens brightness.
The more lumens the brighter the light.
The amount of energy a light bulb uses.
In it we compare the annual energy costs lifespan and light output among a few other features of an led compared to a t12 t8 and t5 high output fluorescent lamp.
A 40 watt fluorescent tube for example is rated around 2300 lumens.
Designed to replace fluorescent tube bulbs these led tubes are available in 8 and 16 watts which replace traditional 25 watt and 40 watt t8 t10 t12 fluorescent tubes.
To compare different light bulbs you need to know about lumens.
The lumens scale indicates the brightness of a bulb and should be used when selecting your new led.
Lumens measure the amount of light created by a bulb whereas watts measure the energy used by the bulb to produce lumens.
An incandescent light bulb s longevity is 2 000 hours on average.
For example a correct replacement for a 60w incandescent bulb would be a 15 watt cfl bulb 60 1 4 15.
Standard 100 watt bulbs produce about 1600 lumens.
Traditionally we ve referred to light bulbs by their watts because most people used incandescent light bulbs and knew difference between a 60 and 100 watt bulb.
On the other hand fluorescent light bulbs provide much more lumens per watt making this type of lamp much more efficient than incandescent bulbs while providing a comparable light output.
Because fluorescent lights are often installed in high ceilings in commercial sites there are additional savings because the frequency of changing bulbs is greatly reduced.
Labels on the front of light bulb packages now state a bulb s brightness in lumens instead of the bulb s energy usage in watts.
If you re wondering how much more efficient leds are than t12s consider these results.
The lower the light bulb wattage the lower the electric bill.
Compact fluorescent lights cfls and leds have a lower wattage than incandescent bulbs but emit the same light output.
