Using the 6:1 ratio, simply divide 30 watts by 6 to get 5 watts. But efficacy varies wildly from manufacturer to manufacturer, so it’s best to check the Lighting Facts label and try to match lumens. Also, a label will sometimes (but not always) tell you that an LED bulb has an equivalent brightness.
How much light does a 6W LED bulb produce?
So a 6W LED bulb will produce between 0.9 and 0.48W of visible light. The claim that a 6W LED bulb produces as much light as a 40W incandescent bulb requires the efficiency of the LED bulb to be 12.7%, which is well within the range of efficiencies that LED bulbs can achieve.
What is the LED bulb wattage equivalent to a 40 watt bulb?
If you have a 40-watt incandescent light bulb that you wish to trade for with an LED bulb, you can divide the wattage by 5. The quotient of 8 would be the LED bulb wattage equivalent. See it’s that easy.

So a 6W LED bulb will produce between 0.9 and 0.48W of visible light.
How many lumens does an LED bulb have?
According to the advert you posted, that LED bulb consumes 6W (power) to get a luminous flux of 500 lumens (lumen is a photometric unit, like candela or lux): https://en.wikipedia.org/wiki/Luminous_flux
Do LED bulbs need 40W?
On the other hand, an incandescent bulb would need to consume 40W (power) to get the same luminous flux. That is what the advert is telling you. You don’t “need” 40W to lighten up a room, that is the power you invest to get the light. LED bulbs have a better return of investment because they are based in a completely different physical phenomenon …
Do you need 40W to light a room?
That is what the advert is telling you. You don’t “need” 40W to lighten up a room, that is the power you invest to get the light. LED bulbs have a better return of investment because they are based in a completely different physical phenomenon (incandescence vs. photoelectrical effect).

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 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 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.
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.
How many lumens per watt?
Now that we understand watts and lumens, we can use both terms to come up with lumens per watt or “efficacy.” 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. LED technology typically produces 70-100 lumens/watt, which means LEDs are about 5-6 times more efficient at producing light than incandescent bulbs. Use this 5:1 or 6:1 ratio as a rough guide when selecting an LED bulb to replace an incandescent bulb.
What is lumens in LED light?
A lumen is a measure of visible light energy. The higher the lumens, the brighter the light. All lighting manufacturers are starting to tell us how many lumens are produced by each of their lighting products. We see these lumen numbers on the Lighting Facts labels found on all new LED bulb packages. It may take a while to get used to using lumens instead of watts, but it’s important in order to make the best lighting choices.
What is lumen in LED?
A lumen is a measure of visible light energy. 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 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.
What is the most efficient way to light a room?
Today’s most efficient way of illuminating and lighting is undoubtedly LED. When compared with older lighting technologies such as Incandescent, Halogen and CFL bulbs, you will find that LED is by far the most energy saving and smart solution.
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.
How many watts does a flame tip LED bulb use?
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.
What is the replacement for incandescent bulbs?
LED light bulbs are quickly taking over as the bulb of choice, replacing incandescent bulbs at a rapid pace now that many countries have instituted mandatory phase-outs.
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.
What is the difference between warm and cool light?
Choose between warmand coollight: new LED bulbs are available in ‘cool’ white light, which is ideal for task lighting, and ‘warm’ light commonly used for accent or small area lighting.
How many hours does a KWh use?
KWh of electricity used over 25,000 hours
Can LED bulbs be dimmed?
