Fluorescent Light Bulb Wattage Vs Incandescent

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.

Fluorescent light bulb wattage vs incandescent. Differences will also occur between types and sizes of light bulbs. One of the most common incandescent bulbs that is used is a 60 watt bulb. When cfl bulbs were first introduced in the 1970s they were expected to spel. Dimmable from 100 to 10 these bulbs have a 200 degree beam angle to cast light in a wide area.

When it comes to choosing the right light bulb knowing the differences between them can be helpful in guiding your buying decision now that you know what an led is i bet you re wondering how they compare to traditional light bulbs like fluorescent cfl s halogen and incandescent. The fluorescent lamp and cfl are more efficient in converting electrical energy to light than the incandescent bulb. Watts of electricity used equivalent to 60 watt bulb. To achieve the same brightness as a 60 watt bulb you would only need a 13 15 watt fluorescent bulb or a 6 8 watt led bulb.

Annual cost of operation based on 800 lumens for 2 hours per day at. Bulbs only come in certain wattages which make equivalent versions slight different. Incandescent bulbs produce a direct light from the heating of the filament whereas the fluorescent bulb produces a secondary light through fluorescent material. 6 8 watts.

For example a correct replacement for a 60w incandescent bulb would be a 15 watt cfl bulb 60 1 4 15. A fluorescent light bulb s longevity is significantly higher from 6000 to 15000 hours. 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. Due to a physical process that is utilized in incandescent bulbs they are sensitive to voltage changes.

Leds require less wattage than cfl for the same amount of light. Around 20 to 20 watts in a fluorescent bulb is the same as 100 watts in an incandescent bulb. While the math for the cfl bulbs is simple the led bulbs are even more energy efficient and durable than compact fluorescent light bulbs. Kilo watts of electricity used 30 incandescent bulbs per year equivalent 329 kwh yr.

An incandescent light bulb s longevity is 2 000 hours on average. A 9 watt fluorescent bulb in this case is equal to a 40 watt incandescent bulb. Leds help reduce greenhouse gas emissions from power plants and lower electric bills. While fluorescent cfl bulbs generate light by sending an electrical discharge through an ionized gas incandescent bulbs emit light by heating the filament present in the bulb.

Designed for bathroom vanities or anywhere a globe bulb is required these bulbs produce light equivalent to a 40 watt incandescent bulb yet only consume 10 watts of power.
