Is LED equivalent wattage to traditional light source?
09 Mar, 2018. LED equivalent wattages to traditional light sources can only be approximate, as they will vary depending on the colour temperature and quality of the bulbs being compared. When comparing different light bulbs and lamps, it is better to compare the lumens that each bulb produces, in order to gain a true like-for-like comparison.
How many lumens is 4 watts?
Luminous efficacy and energy efficiency are measured by the unit lm/W. A 60 watt light bulb can produce 900lm, giving it a Luminous effacy of 900/60, which is 15lm/W.
What is a 3 watt LED bulb equivalent to?
The 3 watt rated bulbs use less power than 4 watt bulbs. A 30 watt fluorescent lamp can be replaced with a 3 watt light. White light, warm light, and colored light can be used.
What is a bright LED wattage?
The brighter the bulb is, the more wattage it has. A 60 watt led is not the same as a 60 watt bulb. It is possible that a 60- watt light may blind you. The lower watt rating is due to the fact that the LEDs are designed to use less energy. This means that using watt to determine brightness is useless.
How many Watts does an LED bulb use?
Now, LED’s have changed the game as an LED bulb the uses 15-Watts is no way similar to a 15-Watts Incandescent. Nowadays, companies rate bulbs through lumens as these give you a more accurate indication of how much light to expect from an LED.
What is an LED lamp?
LED lamps were the most recent lights to be introduced and since then a new method of rating was required since the wattage no longer determined which bulb had the superior brightness.
Why are light bulbs important?
Light bulbs bring objects to life, different lighting temperatures set the mood, they make it safer to walk across spaces and can even decorate and highlight specific locations. There are three main categories of electric lights, each with its advantage and disadvantage.
Do LED lights use less wattage?
Watts do not measure brightness but the amount of power used. Since LED’s use lesser wattage and produce the same amount of brightness, they save much more energy. Other than helping lower the electric bills; most LED bulbs are also dimmable and don’t contain any Mercury.
How many lumens does a 60W bulb produce?
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.
What is the new unit of measurement for light bulbs?
Lumens are the new unit of measurement for light bulbs. For decades, we’ve been buying light bulbs according to wattage. But as energy-efficient, low-watt light bulbs like CFLs and LEDs have become readily available, watts have become an unreliable metric for selecting bulbs.
What does lumens mean in light bulbs?
Instead of focusing on wattage, which measures power or energy use, manufacturers are indicating the brightness of their energy-efficient bulbs according to lumens, which measure light output.
How many lumens does an LED bulb produce?
The old technology of tungsten incandescent bulbs only had an efficacy of about 15 lumens/watt; LED technology can produce about 60 lumens/watt. In other words, LEDs are about 4 times more efficient at producing light than incandescent bulbs.
What is lumens per watt?
Sometimes the term “luminous efficacy” is used. This is a measure of how well a light source converts energy (watts) into light (lumens). The old technology of tungsten incandescent bulbs only had an efficacy of about 15 lumens/watt;
How much energy does a 60 watt bulb use?
A 60-watt bulb consumes 60 watts of energy. Since we used 60-watt incandescent bulbs for so many years, we associated a certain level of brightness with 60 watts. But we can’t do that anymore, since modern LED technology produces more light while using fewer watts.
What does more lumens mean?
More lumens equals a brighter light . All lighting manufacturers are starting to tell us how many lumens are produced for each of their lighting products. We see these lumen numbers on the Lighting Facts labels found on all new LED bulb packages.
How many lumens does a 60 watt LED bulb give?
For example, a 60-watt incandescent light bulb gives approximately 800 lumens; therefore, to replace a 60-watt incandescent bulb with a LED bulb of the same brightness, one should purchase a LED bulb that also gives 800 lumens. A 60-watt incandescent light bulb can be replaced with a 10-watt LED.
What is the difference between wattage and lumens?
Wattage measures the amount of energy used by light bulbs. Lumens measure brightness. Therefore, when replacing traditional lighting with LEDs, the lumens of the old and new bulbs should be matched, not the wattages.
How to contact Superior Lighting?

Do LEDs match wattages?
Many people looking to replace traditional lighting with LEDS assume that the wattages of the old and new bulbs should match up because they, like many others, mistakenly associate wattage with light brightness; however, wattage does not represent the brightness of light bulbs.
How many watts does an LED light bulb have?
Designed to replace fluorescent tube bulbs, these LED tubes are available in 8 and 16 wat ts, which replace traditional 25-watt and 40-watt T8/T10/T12 fluorescent tubes. 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.
What is an LED bulb?
In this style LED bulb, clusters of LEDs are covered by a lens which spreads the light over a wider area, like standard incandescent bulbs. Available in standard Edison bases, these bulbs are used as area lighting for rooms, porches, reading lamps, accent lamps, hallways and low-light applications where lights remain on for extended periods.
How many watts does a globe bulb use?
Designed for bathroom vanities or anywhere a globe bulb is required, these bulbs produce light equivalent to a 40-watt incandescent bulb, yet only consume 10 watts of power. Dimmable from 100% to 10%, these bulbs have a 200 degree beam angle to cast light in a wide area.
How many watts does a flame tip LED bulb draw?
Designed to replace incandescent candelabra bulbs, these flame tip LEDs deliver the equivalent light of 25 – 35 watt incandescent while only drawing 3.5 watts of electricity. Because of the heat sink in the base, light doesn’t disperse downwards as much as a typical incandescent candelabra bulb.
How long do LED bulbs last?
Some manufacturers claim the new LED bulbs will last up to 25 years under normal household use, but this is not proven. Bulb breakage and bulb replacement costs have not been factored into this comparison chart. Incandescent bulbs and CFL bulbs are more easily broken than LEDs, which increases their cost of use.
Is LED dimmable?
Several models are dimmable. Also, because they are 90% more efficient than incandescent bulbs and last 10 times longer than CFLs, the frequency of changing LED bulbs is greatly reduced.
Do LED lights build up heat?
Available in pin base or standard (Edison) base, LEDs are ideal for track lighting. LEDs do not contribute to heat buildup in a room because no matter how long they remain on, they do not get hot to the touch. Also, because they are 90% more efficient than incandescent bulbs and last 10 times longer than CFLs, the frequency of changing LED bulbs is greatly reduced.
How much energy does a 5 watt LED bulb use?
A 5 to 25 watt LED lightbulb can give off the same brightness as a 40 to 100 watt lightbulb. Traditional incandescent light bulbs waste 90% of their energy by giving off much more heat than an LED bulb.
How many lumens does a 60 watt bulb produce?
For Example: A 60-watt incandescent bulb may produce 800 lumens of light, while an LED equivalent would produce the same brightness with only 15 watts.
How do LED lights save energy?
In any commercial building, retail space, school, or residence, replacing outdated lighting fixtures, and installing LED’s can considerably reduce the amount of energy that a building consumes annually. Not only are LED light bulbs more energy-efficient, but they can also save you thousands of dollars in overall maintenance and operating costs.
What to consider when replacing an old incandescent bulb with an LED bulb?
When you are replacing old incandescent or fluorescent light bulbs with a more energy efficient LED bulb, there are a few things you should consider: The higher the lumen, the brighter the bulb! The lower the lumen, the dimmer the bulb! Wattage: Energy use of the light bulb.
