683 lm/w for a pure monochromatic green light source at a single wavelength of 555 nm. This is because a lumen (lm) is measured according to sensitivity of the human eye and the eye is most sensitive at 555 nm.
For a wide-spectrum "white" light source, the theoretical maximum is about 280 lm/W if the luminous energy is evenly spread across the visible spectrum. The number can vary slightly depending on the limits chosen for the visible spectrum and how white light is defined.
What else can I help you with?
What is the maximum sound level that can be reached in decibels, with 1100 decibels being the highest possible value?
The maximum sound level that can be reached in decibels is 1100, which is the highest possible value.
What is the minimum and maximum of Fahrenheit scales?
The minimum value on the Fahrenheit scale is -459.67°F, known as absolute zero, which represents the complete absence of thermal energy. The maximum value is theoretically infinite, as the scale extends infinitely in the positive direction.
What is the maximum vacuum possible?
Theoretical maximum vacuum would be a perfect vacuum where there are no particles present. In practice, the highest vacuum achieved is around 10^-13 torr in ultra-high vacuum systems.
What are the conditions for maximum work done in physics?
The conditions for maximum work done are when the force applied is in the same direction as the displacement, as well as when the force has the maximum magnitude possible. This results in the maximum transfer of energy from one form to another.
What is the maximum resultant possible when adding 3-N force to an 8-N force?
The maximum resultant possible when adding a 3-N force to an 8-N force is 11 N. This occurs when both forces are acting in the same direction.

What is minimum and maximum values of g?
On Earth:Do you mean acceleration due to gravity?Here is your answer minimum value of g=9.8m/s2maximum value =10m/s2 approximately.Elsewhere:Anything positive and finite is theoretically possible.
What is the maximum distance for microwaves?
There isn't one. Microwaves are electromagnetic radiation and have a theoretically unlimited range.
An 802.11b compliant wirelesss lan configuration using DSSS can have a maximum of how many non-overlapping co-located access points?
A maximum of three co-located direct sequence system are possible because channels 1, 6, and 11 are the only theoretically nonoverlapping channels.
What is the maximum possible IQ that a person can achieve?
The maximum possible IQ score that a person can achieve is 200.
What is the maximum possible value of x?
If x is the unknown or variable in an equation it can have many possible maximum or minimum values
What is the maximum possible IQ score that a person can achieve?
The maximum possible IQ score that a person can achieve is 200.
What is the maximum number of decimal places allowed after a decimal point?
An infinite amount of numbers can theoretically be placed after the decimal point.
What is the maximum number of S orbitals possible?
The maximum number of S orbitals possible is 1. S orbitals have a spherical shape and can hold a maximum of 2 electrons.
