AnswersDriveTo replace a 100-watt incandescent bulb, look for a bulb that gives you about 1600 lumens. If you want something dimmer, go for less lumens; if you prefer brighter light, look for more lumens. Replace a 75W bulb with an LED bulb that gives you about 1100 lumens.
How many watts does a 100 watt LED use?
The term “60-watt equal” has little to do with any kind of wattage correlation; a 60W equal LED may use as little as 8 watts to operate. It simply means that the bulb, whether CFL or LED, is able to produce as much light as a 60-watt incandescent.

How many lumens do I need per square foot?
To determine the needed lumens, you will need to multiply your room square footage by your room foot-candle requirement. For example, a 100 square foot living room, which needs 10-20 foot-candles, will need 1,000-2,000 lumens. A 100 square foot dining room, which needs 30-40 foot-candles, will need 3,000-4,000 lumens.

How bright is a lumen?
The brightness, or lumen levels, of the lights in your home may vary widely, so here's a rule of thumb: To replace a 100 watt (W) incandescent bulb, look for a bulb that gives you about 1600 lumens. If you want something dimmer, go for less lumens; if you prefer brighter light, look for more lumens.

What is 12w equivalent to?
Beware of LED bulbs on the market which have a lot bigger diameter, some as large as 90.0mm. 12W LED bulb is equivalent to a 100W incandescent. tungsten bulb must have a minimum light output of 700 - 750 lumens.

What is the lumen scale?
A Guide to Lamp Brightness: Lumen Scale. In the past, consumers have used wattage to rate the brightness of a lamp. Wattage is simply a measure of the amount of energy consumed. Light output, on the other hand, is a measure of luminous flux or simply put, the brightness of the lamp. It is measured in LUMENS.
10
How do you measure a lumen?
Lumen (unit) The lumen (symbol: lm) is the SI derived unit of luminous flux, a measure of the total quantity of visible light emitted by a source. Lumens are related to lux in that one lux is one lumen per square meter.
11
What is 1800 lumens?
40 Watt incandescent lamp produces only 380-460 lumens and uses 40 Watts of energy per hour. 100 Watt incandescent lamp produces 1700 – 1800 lumens and uses 100 Watts of energy per hour. Direct sunlight is around 100k lumens and uses no amount of energy per hour.
12
What is the lifespan of a LED light bulb?
LED Life Expectancy. LEDs have a general life expectancy of 50 000 hrs. If you use your lights for 10 hours a day, this should be 13.7 yrs. If this is correct, then LED's are definitely an investment, even the top of the range bulb would work out to cost £2.55 per year.
13
What is lumens per watt?
A lumen is a measure of how much visible light is emitted by a source. Lumens per watt (lm/W) refers to the energy efficiency of lighting: how much visible light you get for a given amount of electricity. For example, a traditional 60 watt incandescent bulb in the US produces 860 lumens.
14
Are all LED light bulbs dimmable?
Dimmable LED Light Bulbs. While many LED bulbs are now dimmable, not all of them are and not all of them dim daylight lighting in the same way. Since LEDs consume such a low wattage, many types of dimmers do not function with LED in the same way that they do with high wattage load incandescents.
15
What is the equivalent wattage for LED bulbs?
(The point, after all, is that they draw less energy.) For example, an LED bulb with comparable brightness to a 60W incandescent is only 8 to 12 watts. But don't bother doing the math -- there isn't a uniform way to covert incandescent watts to LED watts. Instead, a different form of measurement should be used: lumens.
16
Are LED or halogen lights better?
Halogen bulbs are extremely sensitive to skin oils, which can cause them to malfunction or burst. They last approximately 3,600 hours—three times longer than incandescent bulbs—but are not as efficient as compact fluorescent lamps (CFL) or LED bulbs.

How many watts does a 100 watt LED use?
The term “60-watt equal” has little to do with any kind of wattage correlation; a 60W equal LED may use as little as 8 watts to operate. It simply means that the bulb, whether CFL or LED, is able to produce as much light as a 60-watt incandescent.
18
How much does it cost to run a 60 watt light bulb for 24 hours?
If the bulb is operated for an average of six hours per day, then over the course of a year it will use approximately (6 X 365 X 60) = 131 kilowatts of electricity. At an average cost of 12 cents per kilowatt-hour, the 60-watt incandescent bulb will cost approximately $17 per year to operate.
19
Can I replace a 60 watt bulb with a 100 watt LED?
If your socket says not to exceed 60-Watts, it is referring the dangers of high heat output associated with incandescent bulbs. However, LED's do not emit dangerous levels of heat. Thus, if your fixture says “not to exceed 60-Watts” but you want to use a 100-Watt equivalent LED bulb, this would be safe to do so.

WHAT LED bulb equals 60 watts?
LED Light Bulbs - 60 Watt Equal. With an efficiency up to 80% higher than similar output incandescents, it is certainly safe to say that LED light bulbs like the 60-watt equivalent use less energy than similar incandescent bulbs. You can be sure this is the case thanks to the "60 Watt Equal" in the bulb's name.
