Watts To Lumens Led Chart

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.

Watts to lumens led chart. 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. Click the equivalent wattage in the lumens vs. φ v lm p w η lm w watts to lumens calculation. Lumens to watts calculator watts to lumens calculation.

Output and wattages based on most common products available for each medium screw based light bulb. The light output is 1800 lumens and you want to know how bright it is compared to an old halogen torchiere. 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. After a click on the calculate button you will see the wattage of an equally bright halogen.

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. 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 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.

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. To replace the 40w incandescent with a cfl you d be looking for one with about a 400 lumen output. 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. 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. Watts chart below to shop for the right light bulb for your space. You see an offer for an led torchiere. Energy saving lamps have high luminous efficacy more lumens per watt.

In each case the important factor when choosing the replacement is to get a similar lumens rating. P w φ v lm η lm w lumens to watts table. It has two text fields and two controls the calculate and reset buttons. 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.

Energy saving lamps have high luminous efficacy more lumens per watt. Use the chart above to determine exactly how many lumens are in a watt and vice versa. Watts to lumens calculator lumens to watts calculation formula.
