Lux Calc provides the stage or screen lighting technician with an easy-to-use and handy lighting calculator at his or her fingertips. With Lux Calc you can quickly calculate:

• Power Formula: Provide any two known values (such as watts and volts) to calculate the unknown one (amps).

• Ohm's Law: Much like the power formula, it calculates Voltage (V) = Current (A) x Resistance (R), and all variants.

• Beam Calculations: Variables include beam diameter, beam angle, and throw distance. Input two to figure the third. You can also determine throw distance by inputing a horizontal and a vertical measurement. Supports feet, meters, or any other unit of measurement.

• Conversions: Determine footcandles from lux, and vice-versa.

• Voltage Drop: Calculate voltage drop on a copper conductor for a given amperage and wire length. Also calculates wire resistance.

Lux Calc is provided at no cost to the user and without any ads, a true freeware application!
