You can't without knowing the source of the light as candelas have an allowance for human eye sensitivity built-in, and that varies from light source to light source. For any given light source you can find a lumens per watt figures and work back from that as a lumen is adjusted to human eye sensitivity as well.

How many lumens are in 60000 mcd?

There is no direct conversion between lumens and millicandela (mcd) as they measure different things. Lumens measure the total amount of visible light emitted by a source, while mcd measures the intensity of the light emitted in a particular direction.


What are 13000 MCD in lumens?

13000 MCD (millicandela) is a unit of luminous intensity, not luminous flux like lumens. The relationship between lux and lumens depends on the beam angle of the light source. You would need to know the specific beam angle of the light to convert MCD to lumens.


What is MCD brightness for solar lights?

MCD is short for millicandela But the convertion to other ligthing unit is not simple There is no definitive answer. A millicandela rating is determined by an on-axis measurement of peak intensity at a specific current, not by measuring total light output. Since the light emitted by a diffused LED is spread over a wide viewing angle, the on-axis value may actually be less than a non-diffused LED from which all light output is concentrated in a narrow beam. Thus the total light output of a 20 mcd LED may be greater than that of a 100 mcd LED though the on-axis reading is less. This link provides a wizard to help you http://led.linear1.org/lumen.wiz


How many giga watts is a exa watts?

there is one Giga Giga watt in one Exa watt. So one Exa watt = one Giga Giga watt or 109 Giga watt or one Exa watt = 1018 watt and one Giga watt = 109 watt then one Exa watt = 109 Giga watt or one Exa watt = one billion Giga watt = one thousand million Giga watt


How many milliwatts make one watt?

I think mini watt is an alias for milli watt, so 1000 mini Watts equals 1 Watt
