An average 100-watt incandescent bulb, for example, produces about 1,600 lumens. As benchmarks, for an incandescent bulb, an average wattage for 1,500 lumens is 100; for a CFL, the average is around 25 watts; for LEDs, the average is 18 watts. With low energy LEDs, you get more light with less power consumption. Direct sunlight is around 100k lumens and uses no amount of energy per hour. You will no longer be able to find or buy 100 watt bulbs. A lumen is a measure of the amount of brightness of a lightbulb -- the higher the number of lumens, the brighter the lightbulb. Do the kids like to spend a lot of time there? With the improvements in technology, people are becoming more accustomed to measuring visible light rather than energy. 1600+ 23-30 watts. 18-25 watts. Today, there’s a myriad of bulb options. The number of lumens will also be determined by the color of the walls and fixtures. 230-270. Equivalent Watts and Amps at 120V AC Can you notice anything in front of you? However, you can install many bulbs that produce 100 lumens until you reach the required amount of lighting. In general though, 5000K or cool/daylight white will a appear brighter than 2700K all things being equal but this is due to the higher contrast of such light. Find the efficacy rating. For instance: 40 Watt incandescent lamp produces only 380-460 lumens and uses 40 Watts of energy per hour. This is good brightness for medium-sized 2x AA flashlight. Because 1 kilowatt is equal to 1,000 watts, it is possible to use the formulas above to also convert kW to amps, but watts need to be converted to kW first. Do not sell my personal information. Telephone: (913) 888-0808 The light output of LED lamps continues to increase exponentially year by year. To replace the 40W incandescent with a CFL you’d be looking for one with about a 400 Lumen output. 100 lumens in CFL bulbs give 5-6 watts On average, one watt of compact fluorescent gives 67 lumens while an incandescent bulb produces 14 lumens per watt. Brightness: This is measured in lumens on the label. This is where lumens come in. 100 watts. Divide the lumens rating by 12.57, using your calculator. 150 watts. (See References 2.) The formula for this conversion is lumens = watts x (lumens per watt). Estimated Yearly Cost: This is based on a set rate of usage each day. Kelvin is not a measure of brightness rather it is a measure of color temperature. A good four tube 4 foot T8 fixture will give about 10,000 lumens after fixture losses while consuming approximately 110 watts. The luminous flux Φ V in lumens (lm) is equal to the power P in watts (W), times the luminous efficacy η in lumens per watt (lm/W): Φ V (lm) = P (W) × η (lm/W) Watts to lumens calculation A few years ago, there were only a handful of lighting options. 1000-1110. You may have to consider other requirements like motion sensor lights, step lights, etc. If your lamp is rated to 25.14 lumens, it has an output of 2 candlepower. To get this right, you should be sure of the different spaces you want to enhance the lighting. Because lumens measure brightness and watts measure energy output, there is no simple method for converting wattage to lumens. Depending on the situation, you might be able to use an LED fixture that outputs only 7,000 or 10,000 lumens. The conversion of watts into lumens for a halogen bulb is a simple calculation once the efficacy of the bulb is known. One lumen of light is barely enough to light a trail in the middle of the night. A 72 watt bulb will now be referred to as a “1,500 lumens bulb” or a “2,600 lumens bulb.” Here’s a quick reference guide to see all bulb conversions. Toll-free: (800) 848-4307, Privacy Policy. Check whether there’s big furniture or a desk. You want to find out how much lux the table is illuminated with. Lightbulb brightness in general is measured in lumens (not watts). During a six-hour day, a 60-Watt LED costs only $17.00 a year to operate versus an equivalent 175 Watt MH that costs $77.14 a year. 800-850. In addition to this change, you will now find that light bulbs will no longer be categorized by wattage, but rather by lumens. If you want to light your way to avoid those potholes, you need at least 30 lumens. Multiply your room square footage by your foot candle requirement. To know the number of lumens you need for your living room, you should calculate the square footage. Provides an alternative. Similarly, if you want to replace your 53W halogen light bulb with a modern LED, the LED will probably use between 9 and 13 Watts of energy. This means that you get 10 lumens per watt. A decade ago, 100-lumen flashlights were considered bright enough for soldiers and police officers. 60 watts. Generally, you can use 100 lumens to light the path around your house. If you have a square room 10-feet wide and 10-feet long, then the room is 100sq ft. Let’s say you want to light the room with candles. Thus average lumens per watt figures are 15 for an incandescent bulb, 60 for a CFL and 83 for an LED. The luminous flux result in lumens will be; 5000 lumen (lm) Formula of converting watts to lumen Фv (lm) = P (w) x η (lm / W), which means that the luminous flux in lumens is calculated by multiplying the power in watts by the luminous efficacy in lumens per watt. A standard 40-watt (40W) bulb is equal to 400+ lumens. As a consumer, you should understand the difference to help you make a well-informed decision. 10000 Lumens: Assuming 25% fixture losses overall it’s 45,000 lumens, or about 55 lm/ft².That is kind of dim for a showroom. How bright can the room get when a candle is one foot away from the source? You would probably want to choose an LED bulb that uses 8 to 12 watts and has a lumen rating of 800 to get the same illumination. Of course, you don’t need a lot of luminosity in your living room. Watts to lumens calculator Lumens to watts calculation formula. LED Night Construction Lighting – Requirement and Guide, 100 lumens in Incandescent bulbs give 20-25 watts.

Ten (10) lumens can be enough for backpacking, camping, and hiking activities. Formula of calculating Lumens to watts P (W) = Фv (lm) / η (lm/W), which means that the power in watts is calculated by dividing the luminous flux in lumens by the luminous efficacy in lumens per watt. Therefore, 100-lumen can be used in urban and suburban areas to scan a small backyard, blind attackers, etc. 40 watts. But today, most flashlights go as high as 1000 lumens. Example: A spotlight with a beam angle of 110° and a light output of 470 lumens is mounted at a height of 6.5 ft above a table. Use our kW to amps calculator to solve for kilowatts. The more lumens, the brighter your light will be. 100 Watt incandescent lamp produces 1700 – 1800 lumens and uses 100 Watts of energy per hour.
