Question:
You need to provide sufficient light for a work area, and you determine that 1600 lumens would be adequate. You discover that there are four competing light sources that can deliver that amount of light: a \(100 \mathrm{~W}\) incandescent bulb, a \(100 \mathrm{~W}\) halogen bulb, a \(32 \mathrm{~W}\) compact fluorescent lamp (CFL), and a 16.5 W light-emitting diode (LED) lamp. Each has advantages and disadvantages. You build the following table to help you make a decision. Considering the overall cost over the stated lifetime of each light source, which would you recommend if electricity costs 12 cents/kWh?
