Lumens to Watts Conversion Formula Energy-efficient bulbs are known for their high luminous efficacy, which means they provide more lumens per watt of power consumed. The formula to calculate power (P) in watts (W) is straightforward: P (W) = Luminous flux ΦV (lm) / Luminous efficacy η (lm/W)

Watts: The Ultimate Conversion Guide Lighting Guide Decoding Lumens vs Watts: Your Essential Guide to Understanding Light Bulb Brightness When selecting light bulbs, you may wonder what matters more for brightness: lumens vs watts? Understanding these terms is crucial. Lumens measure the actual brightness you see, while watts indicate energy use.

Lumens (lm) 230 - 375 lm. 400 - 500 lm. 700 - 900 lm. 900 - 1125 lm. 1300 - 1500 lm. Using the chart we can see that if you want to replace a 40W incandescent light bulb with a compact fluorescent (CFL), you will likely need a 7W CFL. Similarly, if you want to replace your 53W halogen light bulb with a modern LED, the LED will probably use.

Formula of converting watts to lumen Фv (lm) = P (w) x η (lm / W), which means that the luminous flux in lumens is calculated by multiplying the power in watts by the luminous efficacy in lumens per watt. The watts to lumen calculator delivers accurate results based on the values entered in the text fields.
Determine the watt rating of a bulb to get the same brightness.
Compare that too LED's where well over 50% of the power consumed produces visible light. Lumens, on the other hand, actually measure the amount of light that a bulb gives off, so it's a much better measurement. In the chart below, we've outlined the light output that you'll get in lumens that you'd expect to get from watts.
Lumen to Watt Comparison
The fundamental issue at hand is how many lumens a 60-watt led light bulb produces. You must divide 60 watts by 5, which equals 12 watts, in order to replace a standard 60-watt bulb with a contemporary LED light. This procedure is standardized. There are 700-800 lumens produced by a 60-watt bulb.
