Fluorescent Light Bulb Wattage Comparison

Lumens measure the amount of light created by a bulb whereas watts measure the energy used by the bulb to produce lumens.

Fluorescent light bulb wattage comparison.

A 40 watt fluorescent tube for example is rated around 2300 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. To compare different light bulbs you need to know about lumens. 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 lower the light bulb wattage the lower the electric bill. A fluorescent light bulb s longevity is significantly higher from 6000 to 15000. However wattage simply represents the amount of energy needed to use the bulb. Compact fluorescent lights cfls and leds have a lower wattage than incandescent bulbs but emit the same light output.

The amount of energy a light bulb uses. 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. 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.

An incandescent light bulb s longevity is 2 000 hours on average. The annual energy cost of an led using a lighting control is 11 28 compared to 27 83 for. Standard 100 watt bulbs produce about 1600 lumens. To replace it with the same intensity led just look for one that rates around 2300 lumens.

The lumens scale indicates the brightness of a bulb and should be used when selecting your new led. Lumens not watts tell you how bright a light bulb is no matter the type of 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. Of course not every fluorescent incandescent metal halide etc lamp will give its lumens. The more lumens the brighter the light. For example a correct replacement for a 60w incandescent bulb would be a 15 watt cfl bulb 60 1 4 15.

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.
