If you are used to an incandescent bulb of 100 Watts in your living room, the LED wattage equivalent will be an LED bulb between 15 to 20 Watts. Take a look at the table below and keep it handy when you make your next purchasing decision about replacing your old inefficient bulbs to energy-saving LED bulbs. LED vs Incandescent vs CFL Wattage Conversion Since incandescents are being slowly phased out, and the newer generations are shifting onto LEDs and other energy-efficient bulbs, the conventional measure of wattage will eventually die out. Almost all of the lower watts in an LED are converted into light output.īasically, wattage does not reflect the truth anymore, purely because LEDs are so efficient that 60W LEDs will be massively bright, compared to the 60W incandescent bulb. ![]() This is why a 90% lower watt LED bulb will shine as bright as a high wattage incandescent. Only 10% makes it to your room as light if you are using an incandescent bulb. Specifically, around 90% of wattage, power, or energy conversion is LOST as heat. This is because the wattage to light and heat output conversion is highly inefficient in incandescent bulbs. ![]() With lesser watts, an LED can give you the same brightness as an incandescent bulb of higher wattage. The wattage of a bulb is simply a measure of how much power is being consumed by your bulb. Going by wattage to predict or determine brightness is not the standard anymore. Why Is Wattage Not An Important Measure Anymore? The LED uses 1/10th the wattage, which directly translates to 1/10th the bills you will be paying and the savings you will enjoy due to the energy-saving technology of LEDs. An LED bulb will use around 1/10th the wattage (6 Watts) of an incandescent bulb to give you the same, or equivalent, 800 lumens bright light.Īn LED will have a wattage between 7 to 10 watts only, and that is the watt equivalent you need to look for if you are in the market for a ‘conventional 60 Watt light output’. So an incandescent that outputs 800 lumens uses 60-Watts to power itself. That level is, in fact, 800 lumens approximately speaking. You associate 60-watt with that brightness level. Now let’s suppose you have always known a 60-watt incandescent bulb to be a certain brightness in your experience. Now, brightness is best and most accurately measured by lumens, and color temperature is measured in Kelvin degrees. It does not now, or has ever before, measured brightness, color temperature, or any other specifications that factor into a purchase of a light bulb.īrightness was associated with the wattage due to an acquired experience of judging the brightness of a 60 Watt incandescent versus a 120 Watt one.īut now, if you go out and buy a 60 Watt LED bulb, you will most likely end up lighting up your whole street! It is just too bright for the same watts. Merely stating, watts only measure energy consumption. How much of this output is heat, and how much is light, is the big energy-saving difference between LEDs and incandescents. But in the setting of electrical circuits and application, watts easily translates to current into voltage.įor example, a 40-watt bulb would convert 40 joules of energy into light output and heat output per second. Watts, or wattage, is the measurement of electrical power, where 1 watt is equal to 1 joule being transferred per second. Let’s take a quick trip down memory lane to science class in high school. LED watts equivalent of an LED bulb is the wattage needed for an LED bulb to tally to the conventional bulb’s wattage and the associated lumen rating, in order to get that same brightness in the LED bulb. The new measure is lumens or watts equivalent to help with the transition. With the everyday use of LEDs nowadays, using wattage to predict brightness does not make sense any longer. In contrast, watts have little to do with brightness, and everything to do with power consumption. Similarly, the wattage of a bulb has been conventionally associated with how bright the bulb will be. And they are still used, but they don’t necessarily mean the same thing anymore. Measures and units like horsepower and candlepower have an apparent history of how the measurement must have come around. What we once used to measure quantities may no longer apply as more and more strict standards are devised with time. As technology improves, our language around it evolves as well. ![]()
