How many lumen are in 1 Joule?
1 lumen = 1 candela per steradian.1 candela = 1/683 watts per steradians (assuming 540nm light wavelength).Assuming that the light is collected from a single steradian:1 Lumen = 1 Candela -> = 1/683 Watt -> Watt = 683 Lumens1 Joule = 1 Watt per Second -> Watt = Joule/SecondHence:683 Lumen = 1 Joule/SecondUnder the above assumptions1 Lumen = 1/683 Joule/Second
How many leds and watts to replace a 250 watt metal halide?
It depends. The Wattage ratings do not indicate how bright any type of bulb is, just what its power consumption is. In general LED lamps put out more light for the power used than metal halide bulbs, but there is no standard as to how much more. Most lamps indicate their candlepower or 'candela' ratings on the package, and the vary by type of bulb and manufacturer. The 'candela' is the SI base unit of luminous intensity.
What is te SI base unit for luinous intensity?
Intensity is measured in Candela. Candela is its SI unit.
How many watt hours does a 2300 watt bulb use?
2300 watt-hours for every hour it operates. Watts x Hours = watt hours.
How many milliwatts make one watt?
I think mini watt is an alias for milli watt, so 1000 mini Watts equals 1 Watt
How many lumen are in 1 Joule?

Light bulbs are measured in units of what?
Light bulb are measured in Candela (Cd) for its luminous intensity and Watt for its power consumed.
What is the unit of luminious intensity?
candela--------------------------------------------The official international definition of candela (1979) is:"The candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 x 10e12 hertz and that has a radiant intensity in that direction of 1/683 watt per steradian".
How many meters are in a candela?
The meter is a unit of length, the candela is a unit of luminous intensity.
How many Watts heat power does a typical candle deliver?
It is reported that a typically candle will deliver approximately 0.981 candela of heat power. Watts are used to describe electricity.PS:That (candela unit) still evades the (universal, desired, direct) "power conversion" (answer) to Joules per second (=Watt, standard, also of heat).It's common sense that a candle's flame, will deliver 1 candle of power (=candela),& tells nothing more.Meaning the question was NOT answered (correctly).
What is Candela Corp's population?
Candela Corp's population is 406.
When was Candela Corp created?
Candela Corp was created in 1970.
What is the population of Candela Municipality?
Candela Municipality's population is 1,672.
When was Culcha Candela created?
Culcha Candela was created in 2001.
When was Tía Candela created?
Tía Candela was created in 1948.
How tall is Vincent Candela?
Vincent Candela is 180 cm.
What is scientific name of candle?
Candela is the current SI unit of luminous intensity, which is equal to 1/683 Watts per steradian with a frequency of 540 THz (lime colour as a specific fequency corresponds to a specific colour of light). A watt is 1 joule of energy per second, a steradian is the 3D equivalent of a radian.
