Watts to lumens led chart.

To replace the 40w incandescent with a cfl you d be looking for one with about a 400 lumen output. 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. Lumens to watts calculator it is a conversion calculator that is used to convert the luminous flux in lumens lm to the electric power in watts w. Use the chart above to determine exactly how many lumens are in a watt and vice versa.

In the calculator you have to select lumens to watts as conversion type enter the value 1800 and select the item halogen lamp as comparison type. For example if you typically purchase 60w incandescent bulbs which produce about 700 800 lumens consider purchasing a lower energy alternative like a 42w halogen bulb 12w cfl or even a 10w led bulb to achieve the same brightness. In each case the important factor when choosing the replacement is to get a similar lumens rating. Watts chart below to shop for the right light bulb for your space.

Energy saving lamps have high luminous efficacy more lumens per watt. It has two text fields and two controls the calculate and reset buttons. Watts to lumens calculator it is a conversion calculator used to convert the electric power in watts w to the luminous flux in lumen lm. It delivers accurate results based on the values entered in the text fields which makes it an effective calculator in performing the conversions.

Energy saving lamps have high luminous efficacy more lumens per watt. This conversion chart will help you find an led bulb similar to. You would probably want to choose an led bulb that uses 8 to 12 watts and has a lumen rating of 800 to get the same illumination. Lumens to watts calculator watts to lumens calculation.

Watts to lumens calculator lumens to watts calculation formula. φ v lm p w η lm w watts to lumens calculation. Actual light output may vary by product. P w φ v lm η lm w lumens to watts table.

The luminous flux φ v in lumens lm is equal to the power p in watts w times the luminous efficacy η in lumens per watt lm w. Actual light output may vary by product. The light output is 1800 lumens and you want to know how bright it is compared to an old halogen torchiere. Similarly if you want to replace your 53w halogen light bulb with a modern led the led will probably use between 9 and 13 watts of energy.

The power p in watts w is equal to the luminous flux φ v in lumens lm divided by the luminous efficacy η in lumens per watt lm w. 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. After a click on the calculate button you will see the wattage of an equally bright halogen.
