1Question7 

Show all work please answer question 7 (in bold)

6) You want to have an illuminance of 1000 lux on the Player #2(under the SPOTLIGHT#2 – the rectangular beam). What is the Luminous Flux (lumen) the lamp need to releases assuming homogeneous distribution of the light in the illuminated rectangle?

A=2x1=2 m2

El=(1000 lux )(2 m2)=

2000 lm

7) if the lamp used is a LED lamp with an efficacy of 80 Lumen/Watt, what will be the power of the lamp?
