How Many Lumens Is A Fluorescent Light Bulb

The greater the lumens the brighter or more intense the light.

How many lumens is a fluorescent light bulb. Average initial new lumens out of the package for a 32 watt bulb at 3500k color temperature is 2850. As a rule you ll replace a standard 75 watt bulb with an energy saving bulb of about 1100 lumens. For example a 4w led bulb is 220 lumens while the same amount of lumens can be found in a standard 25w bulb. Rely on new bulb labeling standards to show lumen output and help you choose the right brightness for your needs.

Leds require less wattage than cfl for the same amount of light. A 40 watt fluorescent tube for example is rated around 2300 lumens. For example a correct replacement for a 60w incandescent bulb would be a 15 watt cfl bulb 60 1 4 15. Lumens are the measure of total light intensity from a single source in this case a tube.

It provides cool white light with an output of 2600 lumens. A rapid start system starts smoothly without flashing. Light bulb color temperature is represented in the unit of absolute temperature kelvin noted by the symbol k. Household fixtures are commonly found in color temperatures on the kelvin scale of 2700k warm incandescent 3000k warm white halogen and 3500k household fluorescent.

A 100 w incandescent bulb produces about 1750 lumens or 137 foot candles a 23 watt fluorescent light produces about 1600 lumens or 125 foot candles. On the low end replace a 40 watt bulb with an energy saving bulb of about 450 lumens. To replace it with the same intensity led just look for one that rates around 2300 lumens. This bulb features alto technology for low mercury content.

While the math for the cfl bulbs is simple the led bulbs are even more energy efficient and durable than compact fluorescent light bulbs. Energy efficient bulbs such as led light bulbs or cfl bulbs use less wattage than a standard incandescent halogen light bulb or fluorescent bulb. Initial light output a lamp s light output in lumens after 100 hours of seasoning. For the home or office the philips 40 watt for the home or office the philips 40 watt cool white linear fluorescent light bulb f40t12 cw supreme is a great lighting source.

But even though an led bulb uses less wattage it ll have more lumens than a standard bulb. How to choose the right kelvin color temperature. The incandescent light for most of us can provide a comparison we know about how bright an old 100 watt light is it produces 1750 lumens or about 17 5 lumens per watt.
