Candlepower (abbreviated as cp or CP) is an obsolete unit of measurement for luminous intensity.It expresses levels of light intensity relative to the light emitted by a candle of specific size and constituents. The historical candlepower is equal to 0.981 candelas.In modern usage, candlepower is sometimes used as a synonym for candela One candlepower would then equal 4*pi lumen. If the wavelength of the light is 555 nm, then 4*pi/683 (or about 0.0184 watt) would be the equivalent power. In the case of white light, that number.. ›› Definition: Watt. The watt (symbol: W) is the SI derived unit for power. It is equivalent to one joule per second (1 J/s), or in electrical units, one volt ampere (1 V·A). ›› Metric conversions and more. ConvertUnits.com provides an online conversion calculator for all types of measurement units. You can find metric conversion.
The candela (/ k æ n ˈ d ɛ l ə / or / k æ n ˈ d iː l ə /; symbol: cd) is the base unit of luminous intensity in the International System of Units (SI); that is, luminous power per unit solid angle emitted by a point light source in a particular direction. Luminous intensity is analogous to radiant intensity, but instead of simply adding up the contributions of every wavelength of light. One lumen is = 0.001496 watts. This is pretty simple, after you have your total number of lumens from step 2. You take the total number of lumens and multiply it by 0.001496 watts (538 x 0.001496 = 0.805 watts/square meter)
Candlepower (abbreviated as cp) is an obsolete unit measuring luminous intensity, equal to 0.981 candela. The candela is the luminous intensity, in a given direction, of a source that emits.. 1 candlepower = 0.079 lumen Thus, to convert from candlepower to lumen, you can multiply the candlepower measurement with 12.57, and to convert from lumen to candlepower, you can simply divide the lumen measurement by 12.57. For example, a 40-watt lamp rated at 500 lumen has a candlepower of (500 ÷ 12.57) = 39.8 cd A measure of radiant light from a standard candle that falls on one square meter of surface area one meter from the source. Micromol: One micromol per square meter per second (umol.m.2 s 1). A unit of measure of the amount of light hitting a surface that is in the range of 400-700 nanometers. WM.2: Watts per square meter (WM.2). A unit of. The next thing that you can do is to calculate the number of watts. This is very easy to do once you have converted into watts. One lumen is equal to 0.001496 watts. This means that you simply need to take your answer to step 2 and multiply it by 0.001496. In our example, 538 x 0.001496 equals 0.805 watts per square meter
The term candlepower - now mostly obsolete - was coined in 1869 according to Merriam-webster, and refers to a unit of luminous intensity. Between 1869 and 1948, a unit of candlepower was measured from a candle that was made from pure spermaceti (wax from sperm whales), weighed one-sixth of one pound, and burned at 120 grains per hour Watts and candlepower are two very different measurements. Explaining watts and candlepower help to provide the reason. Watts. Watts is a measurement of the current draw. A watt is the unit of electrical power equal to 1 ampere (amp) under a pressure of 1 volt. (Its also equal to 1/746 horsepower for what it's worth) Watts are also a measure of power (volts x amperes) input into an electric lamp. I notice that physicists seem to avoid using the term candlepower, but I'm taking the unit of candle power to be the candle and 1 candle is 1 lumen per sterradian One fixture is a light at 130 lumens per watt. The other is a light at 180 lumens per watt. To produce 20,000 lumens, the first light needs 153.84 watts. The second light only needs 111.11 watts. That's a difference of 42.73 watts. This is what saves you money on your lighting bill
One foot-candle equals one lumen of light density per square foot, while one lux equals 1 lumen per square meter. To better understand lighting levels and what these figures mean, think of some typical natural lighting situations. Full daylight typically equals about 1,000 foot-candles, while an overcast day would have only 100 foot-candles of. . To put it another way, a standard 60 watt light globe produces around 750-850 lumens of light. 1,000 lumens flashlight is able to produce a beam range of 150 to 200 meters
Foot candle (lumen per square foot) is a non-SI unit of illumination. 1 foot candle (fc) is equal to 10.76 lux. The other common illumination units are flame, lumen per square meter, nox, phot and watts per square centimeter Picture a candle set in the middle of a sphere measuring 0.60 meters (2 feet) in diameter. If we cut a hole that measures 0.09 square meters (1 square foot) in the centre of this sphere, the light that shines through is what we define as a lumen. A foot-candle equals one lumen per square foot. This is a British measurement
One fixture is a light at 130 lumens per watt. The other is a light at 180 lumens per watt. To produce 20,000 lumens, the first light needs 153.84 watts. The second light only needs 111.11 watts The answer is that energy emission of a candle is the equivilant of somewhere between 160 and 210 watts
A tungsten (or other) lamp will convert electricity to light, but the conversion ratio or equation is not linear, or even first order. Lumens = MSCP x 4 Pi. Or, 1 MSCP=12.57 Lumens (MSCP is Mean Spherical Candlepower) 1 watt for 1 second = 1 Joule How Many Watts Is a Foot Candle? In order to calculate your number of watts, you must know that one lumen equals 0.001496 watts. After you have your total number of lumens calculated, you take the total number of lumens and multiply that by 0.001496. For example, 538 lumens x 0.001496 watts = 0.805 watts per square meter
One lumen is about the same brightness as a one birthday candle from a distance of one foot from you. To put it another way, a standard 60 watt light globe produces around 750-850 lumens of light. 1,000 lumens flashlight is able to produce a beam range of 150 to 200 meters Watts (W) and Kilowatts (kW): Watts are the SI unit of power. Kilowatts are equivalent to 1,000 Watts and are the most frequently used unit of electrical power. Power in general is defined as energy over time. Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s
lumens (lm) x 0.079 58 = spherical candle power lumens (lm) x 1.496E-03 = watts (W In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V) 50 W HID gives you 20 million candlepower and 4500 HID lumens gives 15 million candlepower, so your light puts out somewhere between 20 and 15 million cp. Let's say 17 million, but because there is a wide tolerance on this value Step 1. Understand Watts. Watts are a measure of energy consumption. When we pay our electric bill, we pay for the number of watts we 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
Candlepower (abbreviated as cp) is an obsolete unit measuring luminous intensity, equal to 0.981 candela. The candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation that has a radiant intensity in that direction of 1⁄683 watt per steradian. a sphere measures 4π ≈ 12.56637 steradians 1. Lumens, Candlepower & lux confuses the heck out of me, and 2. It seems apparent that not all 3-watt bulbs are equal Watts is the only measurement available for a flashlight unless it specifies the background color and distance from an object (preferably a volume is given or assumed infinite) Quantity : Reference Unit : is equal to : Conversion Factor : Unit : 1: foot-candle = 0.00107639104167 : centimeter-candle: 1 = 0.25 : flame: 1 = 1 : foot-candle The electric power P is equal to the energy consumption E divided by the consumption time t: P is the electric power in watt (W). E is the energy consumption in joule (J). t is the time in seconds (s). Example. Find the electric power of an electrical circuit that consumes 120 joules for 20 seconds
A kilowatt-hour (kWh) is 1,000 Wh, so 400 kWh is 400,000 Wh. In some cases, MyEnlighten will display energy as megawatt-hours (MWh), which is one million watt-hours. So what is the difference? In a nutshell, watt-hours measure amounts of energy for a specific period of time, and watts measure rates of power at a moment in time. A common analogy. candlepower. One candlepower is the radiating power of a light with the intensity of one candle. This unit is considered obsolete as it was replaced by the candela in 1948, though it is still in common use. 1 candlepower is equal to about 0.981 candela Divide the watt figure by 1,000 and multiply the answer by your utility's kilowatt-hour price. For an average incandescent, at 16.5 cents per kilowatt-hour, 1,500 lumens for an hour runs 1.65 cents. A CFL and an LED would average around 0.41 cents and 0.30 cents, respectively
A measurement of 1 lux is equal to the illumination of a one metre square surface that is one metre away from a single candle. The diagram below helps to visualise this more easily. One lux (1 lux) of light is a measure of the light density, equivalent to 1 lumen per square metre (lm / m^2) - 1 square meter (M 2) = 10.7638 ft 2 - 1 LUX is defined as 1 lumen/ M 2 of a surface; thus 1 LUX= 0.0929 FC, - 1 foot candle (FC) is 1 Lumen/ ft 2 of a surface; thus 1 FC=10.7638 LUX - There are 12.57 square meters on the surface of a 1 meter radius sphere. In real life objects are illuminated and measured in LUX New Rechargeable 1 Million Candle Power Superbright LED Torch With AC/DC Chargers.

Good spotlight for the price. 1 million candle power is good enough for a boat spotlight. Light draws 8 amps making the light approx 96-100 watts. Not bad for something that can shoot light that far. Heavy-duty cord of modest length. Not too bulky. Good grip. I like the trigger action with the trigger lock - like a power tool A person in the hottest times from the year for churches to deliver out candles is for the duration of the Xmas season. In the end, Xmas represents the day when baby Jesus was born in the manger. This is certainly linked to 1 million candle power equals how many lumens. 1 Million Candle Power Spotligh A quick Google search yielded an article that says 1 lumen = 1 foot-candle, and that to an approximation, dividing the lumens by 0.07958 will give an approximation of candlepower. Some 60 watt soft white long life bulbs here claim 780 lumens with a 1500 hour life Table of Power and Heat Flow Conversions . Note that you must first complete the operations in the Multiply By column in order to have the correct factor. For example, converting calorie per hour (IT) to watts, 4.1868/60/60 is 4.1868 divided by 60, divided by 60 which is equal to 0.001163 A foot candle is the light intensity (in Watt/steradian) of such a light source at a distance of one foot. A steradian times a radius of one foot is a square foot of area. So a foot candle is 1/683 Watt of light per square foot. Edit: The total output of an omnidirectional one candella light source is 4 pi/683 Watt or .0184 Watt. Wolfram Alpha.
A standard candle has radiant intensity equal to 1/683 W/sr. [The unit of measurement is watts per steradian. The steradian (sr) is the standard unit for solid angles: If a patch on the surface of a sphere of radius r has area A, then the solid angle subtended by the patch at the center of the sphere is A/r^2 Proof of 1 hp equal to 746 watts. HP = Horsepower . HP and Watts are both units of power. Power can be electric or mechanical, and can be converted between the two. Any conversion will be less than 100 % efficient. It is only for historic reasons that electrical power is measured in Watts not hp, like the way that tyre widths are in mm but rim.

This practical unit of electrical energy is equal to 1 watt of power used continuously for 1 hour. The term kilowatt hour (kWh) is used more extensively on a daily basis and is equal to 1,000 watt-hours. The EFFICIENCY of an electrical device is the ratio of power converted to useful energy divided by the power consumed by the device Though the two terms may be easily confused, it's relatively easy to understand lumens and what to look for when shopping for light bulbs. The word lumen is the standard term used to describe light output—for example, a candle gives off about 12 lumens, whereas a 60-watt soft white incandescent light bulb produces about 840 lumens. However, not all 60-watt bulbs are alike Unit Descriptions; 1 Ton of Air Conditioning: Defined as 2000 lb m (1 short ton) ice melted in 24 hours.

BTU of a candle Now, how many candle do we need to produce 10 kBTU/h? It turns out that the energy output of candles is well studied: From measurements of the mean mass loss rate (0.105 g/min) and hceff (43.8 kJ/g), the steady-state heat release rate from the candle was calculated as 77±9 W Which can be converted to be 263 BTU/h. Sourc The amount of light generated by 32-watt T8 fluorescent lamps varies considerably from one lamp model to the next and from one manufacturer to another. Figure 1 shows the range of values for rated initial light output that are presently published for 121 lamp models by nine manufacturers for different correlated color temperatures (CCT) How many calories per second are in 1 watt? The answer is: 1 W equals 0.24 cal/s. 0.24 cal/s is converted to 1 of what? The calories per second unit number 0.24 cal/s converts to 1 W, one watt. It is the EQUAL power value of 1 watt but in the calories per second power unit alternative Watts Watts are how much electrical power the lamp consumes. If all lights were equally efficient that might be useful to know, but they aren't, so it isn't. What matters is how much visible light is produced, and that's measured in lumens. I said it isn't useful to know the watts. I lied. It is useful to know if a dynamo lamp is compatible with a generator and slightl Thanks. If I grasp something out of the definition, the candela is 1/683 of a watt through I totally have no idea about the steradian d even less concerning the lumens. 1500 candela is 2.19 watt i.e for 60 watts, i need 41095 candela
