Imagine that you’ve just received a promotion at work. while your new office is being renovated, you will need to spend just a few weeks working in a storage area re-purposed to be a temporary office. an office assistant will have their desk in this temporary space as well. there are no windows, just two desks in a small space, and only one source of light; an led light fixture suspended from the roof of your office. the diagrams on the last page contain the dimensions and layout of your office. you decide to apply the concepts of illumination you learned in class to evaluate the lighting conditions of the room. the building manager who is you get set up mentions that he recently replaced all the incandescent (filament) bulbs in the building with these led fixtures have saved the company a bunch of money. he mentions that the old incandescent bulbs were inefficient, only providing 15 lumens for every 1 watt of electric power. he picks up an old incandescent bulb, which is labeled ‘100 w’, holds it next to the light fixture, and exclaims: "with the same power consumption, the new light fixture provides 5 times as much illumination as the incandescent bulb! i even checked with my photometer! "4) when the led is turned on and all other source of light in the room are off, it does not seem to be sufficient illuminance to support the work you’ll do, which could most accurately be referred to as "computer work". referring to mil-std-1472g, does this meet the minimum illuminance required for this work? justify your answer with specific values.
