Fluorescent Light Bulb Wattage Comparison

The lower the light bulb wattage the lower the electric bill.

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. The annual energy cost of an led using a lighting control is 11 28 compared to 27 83 for. 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. 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.

The more lumens the brighter the light. The amount of energy a light bulb uses. 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. An incandescent light bulb s longevity is 2 000 hours on average.

However wattage simply represents the amount of energy needed to use the bulb. 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. To replace it with the same intensity led just look for one that rates around 2300 lumens. A 40 watt fluorescent tube for example is rated around 2300 lumens.

Standard 100 watt bulbs produce about 1600 lumens. 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. 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. To save the most money on your electric bills replace your bulbs with the lowest wattage for the desired lumens brightness.

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. In general a simple rule to follow to replace an incandescent with an equivalent in light output cfl bulb is to select the cfl bulb that has 1 4 watts compared with the replaced incandescent bulb. The lumens scale indicates the brightness of a bulb and should be used when selecting your new led. The greater the lumens the brighter or more intense the light.

Lumens measure the amount of light created by a bulb whereas watts measure the energy used by the bulb to produce lumens. To compare different light bulbs you need to know about lumens. Compact fluorescent lights cfls and leds have a lower wattage than incandescent bulbs but emit the same light output. Of course not every fluorescent incandescent metal halide etc lamp will give its lumens.

If you re wondering how much more efficient leds are than t12s consider these results.
