Watts is a measure of a light source’s power output, not the level of brightness. However, new energy-efficient technology now means that using watts isn’t an accurate indication of a bulb’s power. As technology continues to improve, more lumen will require fewer watts, improving energy efficiency. Lumens are the specific measurement for how much light a bulb emits, while wattage measures the amount of electrical power.
Well-planned lighting can enhance the functionality, aesthetics, and mood of a room, making it essential for architects, interior designers, and homeowners. Lumens have replaced watts as the standard measurement for light bulb brightness, offering a more accurate representation of light output and efficiency, particularly important for energy-efficient LED bulbs.
Lumens indicate the brightness of the light emitted from a bulb, while wattage measures the amount of energy a light bulb consumes. The higher the wattage, the more energy the light operates, and the more it will cost. Lamp wattage is the amount of energy needed to produce an amount of light, and the higher the wattage, the brighter the light but also the more power it uses.
In summary, wattage is a critical parameter in lighting design that influences brightness, energy efficiency, and electrical load. A lighting device with a high wattage value consumes more electrical power and increases your energy bill significantly. Lumen output is the specific measurement for how much light a bulb emits, while wattage measures the amount of electrical power.
📹 Difference Between Lumens and Watts? – THE BRIGHTNESS OF LIGHTS
A lot of people still use wattage to talk about the brightness of lamps, when in reality lumens are the measure of light output.
What is the purpose of watts in lighting?
The wattage of a light bulb indicates the amount of energy it consumes over time. While a higher wattage generally corresponds to a greater electricity usage, this does not necessarily correlate with the bulb’s brightness.
What is the significance of watts?
Watts and watt-hours are two different units of measurement for electrical power. Watts measure the rate of power at a specific moment in time, while watt-hours measure the rate of power over a specific period of time, such as an hour. One watt-hour is equivalent to one watt of power flow over an hour. To determine the number of watts needed to power an RV or boat off-grid, first list all the electrical devices you want to run, then calculate the wattage and running time of each device. This helps you determine the appropriate number of watts for your needs.
What is more important, watts or lumens?
A higher lumen rating signifies a bulb with greater luminosity, whereas a lower wattage rating indicates a reduction in power. Consequently, a bulb with a high lumen count and a low wattage rating is more energy-efficient. In order to ascertain the energy efficiency of a given bulb, it is necessary to determine the lumen per Watt value, which represents the number of lumens emitted by the bulb for each Watt of power consumed. For illustrative purposes, one may consider a 10-Watt bulb emitting 1, 000 lumens as a point of reference.
Does higher watts mean brighter light?
A lumen is a measure of the amount of light a bulb produces, or light bulb brightness. A standard 40W bulb has 400+ lumens, indicating a higher output of light. Watts measure energy output, while lumens measure brightness. Energy-efficient bulbs like LED or CFL use less wattage than standard incandescent, halogen, or fluorescent bulbs. However, LED bulbs have more lumens than standard bulbs, as they use less energy to produce the same amount of light.
For example, a 4W LED bulb has 220+ lumens, while a standard 25W bulb has 220+ lumens. This shows that a standard bulb can achieve the same brightness with less energy, making the light bulb more efficient.

What is the importance of wattage?
Wattage is a crucial factor in determining a device’s performance, efficiency, and safety. Higher wattage can lead to more power but also energy consumption, heat generation, and potential hazards like electric shock, fire, or damage to sensitive components. Lower wattage may result in lower power output, slower operation, or reduced functionality. It’s essential to choose the right wattage for your needs and use it correctly and safely. Highlighting functionality is a technique that emphasizes the most important features of a device or system, often using visual aids like diagrams, charts, or illustrations.
Can I use a 9 watt LED in a 40 watt lamp?
The installation of an LED bulb that exceeds its fixture or socket wattage rating is generally safe as long as the actual wattage of the bulb is within the limits of the socket or fixture. This is especially true if the socket has a maximum wattage rating of 50 WATTS, as this can cause potential safety hazards. Therefore, it is essential to ensure that the LED bulb is properly sized and installed within the specified wattage limit.
Is it better to have higher watts?
Appliances with higher wattage are capable of delivering greater power and heat than those with half the wattage. However, this increased capability comes at the cost of greater energy consumption.
Does wattage matter in lighting?
The right wattage light bulbs are crucial for maintaining a home’s electrical system’s efficiency. Overloading the system with higher wattage bulbs can lead to overheating, electrical malfunctions, and fire hazards. By following wattage recommendations, you can optimize energy consumption of your appliances, reducing daily energy waste and utility bills. In essence, using the right wattage bulbs not only ensures safety but also saves money on energy bills.
Is higher watt light better?
Wattage refers to the energy required to produce a certain amount of light. Incandescent lamps were introduced to improve efficiency, producing 380-460 lumens and using 40 Watts of energy per hour. However, advances have been made since then, including the introduction of fluorescent and compact fluorescent lighting, metal halide, low pressure sodium, and high pressure sodium. Fluorescent and compact fluorescent lighting produce better lighting with lower wattage, but environmental factors must be considered.
Metal halide, LPS, and HPS produce better lighting than standard incandescent but are typically higher in wattage and use more power than CFL or LED counterparts. As a result, 40 Watt incandescents are now replaced with 9 Watt CFL or 4 Watt LED, 60 Watt incandescents with 13 Watt CFL or 7 Watt LED, and 100 Watt incandescents with 32 Watt CFL or 15 Watt LED.
📹 How To Understand Watts vs. Lumens
There have been some major changes in lights in recent years because of the intro of power efficient LED bulbs. Acquainted aged …
I’m normally a big fan but you kind of blew it on this one. Mostly kidding! A few clarifications if you don’t mind. 1. You left out that MOST fixtures(luminaries) before LED are rated in specific watts or maximum watts. 2. A 120 volt lighting branch circuit that is 20 amp rated, can be connecting up 1920 watts, not 2400 watts. Lights are considered in NEC a continuous load and circuit breakers are rated at 80% for continuous loads. (20x.8= 16×120=1920). 3. Us (as you called us) old timer” designers did care about lumens! We had to do the lighting calculations as well as branch circuit calls! We had to make sure the correct amount of light was in the right places!! 😊😊. Having some fun with the last one. Be careful, I’m perusal to make sure you do not mislead someone. Respectfully, Kevin
Watts is a function of the applied voltage & the current through a circuit. A heating element in a ceramic sleeve might be rated at 500w but there would be no light emitted because the energy is radiated as Infra Red heat, beyond the visible part of the spectrum…Lumens or LUX indicate how much of the applied energy is converted into light in the visible part of the spectrum.
Hey, Good article btw. Quick question. So my parents have some lamps and light fixtures hanging from the roof (In the kitchen) that say “60W Max To Avoid Fire Hazard” or something like that. I bought an LED Lightbulb with the 100W written on the outside. Can I use those light bulbs (LED’s 100W) even tho the roof fixture and one of the lamps say “60W Max” for example? I’m just afraid to install them and use them and then a fire breaks out jaja. Idk. I’m just sketchy about using them. I thought maybe since the house was built like back in the 50s it wouldn’t handle the new Lightbulbs (LED Lightbulbs) measuring 60W, 70W, Or even 100W+. Thanks in advance and I hope my question made sense to you😅
Damn it Justin! You sure know how to say what you mean, and mean what you say…and I can definitely relate😂🤣. Hi Justin, I’m feeling that same energy as it relates to the term “Luxes” as it relates to desk led light swing lamps, but also, blacklight UV flashlights for authenticating documents. However, I notice that lux numbers are hardly acknowledged (hidden), but strongly considered when purchasing work tools for the field of work described above. Is there a way to determine “lux” measurements based on the amount of lumens “advertised” without having to purchase a lux meter? Thanks, Linda.
You made good points on lumens and the kelvin scale, but you understated the importance of watts the first thing to say when making recommendations for light bulbs should be watts. Wattage Max labels on fixtures are important to avoid fires or overheating to understand how many lumens you want In that fixture you have to understand the max that it can handle in terms of watts before lumens.
Really good stuff. Yesterday my buddy and I filmed our first sketch and I used some random lights from home to make a 3-point lighting setup and after everything was filmed and I imported articles to my laptop I discovered that a lot of the shots were underexposed. So I started to google lightning specific stuff and found out my poor little lights had 500 lumens. This article helped me clear out some stuff. Since studio lights go way higher in lumens, then it now makes sense.
I like it to be bright in my room, 150w, so I got 4 x 15w LED bulbs, hacked them down to around 12w, as the people that make them over clock them and they run to hot, I have already taken 2 back as the casing had cracked, after 6 months, that is before I hacked them, I had to get 2 B22 male to B22 female Y junction, they are hard to get, lots of B22 to E27, by hacking the bulbs, they will last around 5yrs plus instead of 2yrs,
So I have a light fixture attached to my fan and each spot for a bulb (there’s three spots) says 4W max… I just ordered some led light bulbs that can change color and stuff from Amazon and there rated at 5W each… does this mean I can’t use these bulbs or since they are leds and the bulbs that are in there I’m pretty sure aren’t leds mean I can use these. Or could I use only two of them so in total it would be less Wattage? Thanks I’m advance and sorry for the long comment/question!
Please do not get offended by my suggestion, I’m only one opinion out of all your followers and viewers. But here goes, pro’s, this is great, I can use my imagine the way you use your arms when you explained 40,000 lumen Niagara falls truly give a great idea of how bright lumens in lights is. Con’s I think you reslly do not need to use such profanity to describe or explain how good something is or how great it is. I wanted to subscribe to your website but I dont appreciate the foul language, though you do a wonderful job of explaining electrical lingual.
Great article!! Well spoken with clear information. I’m just getting started about lights and I clearly understood the concepts. Question: So, when calculating how much light I need to illuminate a space, do I simple add up how many lumens outputted by each light bulb or is there a special formula for that?
