Question

Assuming the two lamps are used 12 hours/day over the whole year, estimate the yearly energy cost. The energy cost 10c/kwh.

The lamps are: 

1) 2x22W, T-5, fluorescent, 3000 lumens/lamp, rated life 20,000 hours

2) 3x32W, T-8, fluorescent, 2800 lumens/lamp, rated life 18,000 hours

 

Expert Solution
Step 1: Stating the given data

lamps used per day = 12 hours

2x22W, T-5, fluorescent, 3000 lumens/lamp, rated life 20,000 hours

3x32W, T-8, fluorescent, 2800 lumens/lamp, rated life 18,000 hours

Asked to estimate the energy cost per year?
