To help you get an idea of the lumen scale, a standard watt bulb puts out around lumens of light. Like miles-per-gallon in a car, the lumens-per-watt rating measures how much light that particular bulb produces per watt of power used, which tells you how energy efficient it is.
Under the new system, when shopping for a light bulb, you should first look for the bulbs that produce the number of lumens you need.
The lumens-per-watt rating is an average, since light bulbs become less efficient as they age. Incandescent bulbs produce around 20 lumens per watt, while some of the newer LED bulbs pack a whopping lumens per watt or more!
To qualify for Energy Star, light bulbs must meet certain lumens-per-watt standards. Hi, I would like to understand how I can choose energy saving lights when I compare the wattage and Lumens.
Current LED and CFL bulbs are still very crude and poor in quality compared to incandescent bulbs. In addition, lumens listed for bulbs appear to worthless in comparing bulbs.
I have a 65W BR30 incandescent indoor flood with a lumen brightness listed which is just as bright as a 60W incandescent bulb which I would expect but has a listed brightness of lumens.
When I bought a LED flood of lumens supposedly a 65W replacement, it was considerably brighter than my other 65W incandescent bulbs.
Not only that, this supposedly dimable LED flood light was still much brighter and the lowest dim setting than all of the incandescent flood lights.
How can consumers make accurate decisions with such lousy markings? Warmer temperatures are closer to candlelight, sunrise, and sunset while cooler temperatures are closer to daylight and pure white.
The issue is that between a warm bulb and a cool bulb of equal lumens, the cool bulb will APPEAR to be brighter because of how humans PERCEIVE warm and cool color temperatures.
The lumen scale is based on the actual light output, not on what different species of plant and animal life perceive the light output to be. Understanding this you can actually save a little by using dimmer lower lumen cool light bulbs when replacing existing incandescents.
TH community members helping other TH community members — we love it. I need lights that will provide as close to sunshine as possible to prevent health problems.
I recently installed four low profile LED fixtures in a customers basement. The ceiling was low and they worked well, nice light and came on immediaitatly.
The customer also bought a LED hi hat for over the stairs. The probllem is there is a delay. The manufacture says that a three second delay is exceptable.
I believe we have a way to go before all the glitches are ironed out. It sure would be helpful to have a chart available to compare watts to lumen.
Untill the consumer gets familiar with the changing of everyday light bulbs. Right now I know that a watt is what I need for a certain job.
If the salesmen would tell me to just use a lumen new led bulb I would have absolute no idea if that would give me the equivalent amount of lighting.
The charts I am thinking of could be hanging at the light-bulb department at stores were you can just take one with you home.
This is my 5cents worth of suggestion. Thanks for giving me the opportunity to suggest this. My question: how many lumens do I need from my new LED fixture to match the brightness of the existing fixture?
Great article! I wondered about lumen selection when I am on a paved trail for bicycles and am caught out in the dark by not preparing for quicker sunsets.
Great article, thank you for the information. An Lumen LED with a color temp of 2,k warm white will not APPEAR as bright as the same rated bulb with a 3,k, or higher, Daylight bulb.
The lumens are the same, but your eyes perceive it differently. It is not an integral part of the bulb as it is in an incandescent bulb.
The color will look a little funny until you get used to it. The warm white may look too orangy, and the daylight may look too blue-white.

CFLs were invented to let users enjoy white fluorescent light despite having regular tungsten-style light sockets. They can last up to 10, hours and release colder light.
LEDs use electrons, photons, and diodes rather than gas and glass. For home use, most people buy 60W tungsten bulbs, which produce to lumens of light.
And from experience, we have a fixed idea of how bright we think a 60W bulb is. So we have a mental image of what lumens look like.
With traditional tungsten bulbs, it takes 1W to release 15 lumens. But with LEDs, 1W produces 60 lumens or more.
So a 60W tungsten bulb may emit lumens of light, but a 60W LED light could release over 2, lumens per bulb. That could easily ruin your eyesight, so you need to be really careful.
Meanwhile, a 60W CFL will give off nearly 3, lumens. That means for the same number of watts, LED bulbs produce four times the amount of visible light.
A 60W tungsten bulb is therefore similar to a 15W LED. But you may be renovating, so you might want your room to have a different set of lights.
Maybe you want to replace a single bulb with a chandelier. Or you might want to swap out the pendant fixture for light strips or string lights.
LED light strips are sometimes backed by self-adhesive tape. So instead of mounting one central 60W bulb, you might opt for a strip of 5 mini bulbs or diodes.
In that case, every LED chip would be 3W so a total of 5 LED cups amounts to 15W. You can get the same lm luminosity from 2 CFLs.
Check the table below to understand the concept more clearly. LED stands for Light Emitting Diode. These lights are known for producing bright illumination through minimal power usage.
So your bulbs will be brighter and prettier but your power bill could be up to four times lower.
These lights come in different configurations. Another bulb style is the LED cup. For example, lumens has brightness equivalent to a watt bulb.
Estimated Yearly Cost: This is based on a set rate of usage each day. While your actual use may vary, the dollar amount noted will give you a good baseline.
Life: The overall expected life of the bulb, often in years. This is also based on estimated daily usage. Warmer light in the K range is way you'd expect from a standard incandescent.
The K stands for kelvin. Energy Used: Here is wattage in its proper place. And with a shift to more energy efficient light sources, you will not see the 40, 60, 75 or watts like you used to.
These days, you will more often see values in the twenties, teens or even single digits. How Do I Choose an Energy-Efficient Light Bulb?
If you love incandescents, look to halogen. It is not illegal to own and use the existing standard incandescent bulbs, but once retailers' supplies are depleted, that's it.
But the incandescent bulb isn't dead. Moving forward, the general service bulbs that will be available will include halogen light bulbs, which is actually a subcategory of incandescent bulbs.
Also, like standard incandescents, they're dimmable and come in a range of sizes, shapes and colors.
Especially in LEDs, the manufacturing quality of the bulb varies, with lesser bulbs not lasting as long as their better-built counterparts.
Lighting experts currently recommend only buying ENERGY STAR-qualified LED light bulbs, as they must pass numerous quality tests to earn that designation.
Look at the bulb's Color Rendering Index CRI. This will help with CFLs especially. You want your fluorescents to have a good CRI , which is the measurement of how true the color of an object looks under the bulb's light.
A good CRI for most indoor residential applications is 80 or above. A really good one is 90 or above, which is an excellent choice for bathroom vanity lights.
