Question

Conduct a visual survey of lighting in the selected room or rooms. Take your best guess on identifying lighting types and wattages. Safety tip: If you decide to physically inspect the bulbs, make sure to turn the power off and wait until they are cool! Some tips:

Incandescent screw-in bulbs are usually 60W
Compact fluorescent lamps (CFLs) are usually 14W
T8 Fluorescents bulbs are 32W each and has a ballast factor of 0.88
Ex: A fixture with 4 x32 W bulbs would use 4 x 32W x 0.88 = 113W

1. If you can't find your non-LED lamp or fixture, consult this Home Depot guide.

2. Estimate the number of hours each bulb or fixture runs in a year.

3. Estimate the annual consumption and cost for running lighting in your selected room or rooms.

4. Recommend a replacement program to replace existing lighting with LED bulbs and fixtures and lighting controls. To find a similar LED bulb or fixture as your existing lighting, either consult your local hardware store website or use the ENERGY STAR Product Finder.

If all your existing lighting is already LEDs, assume your existing lighting is a mixture of compact fluorescent lamps and T8 fluorescent bulbs.

5. Calculate the estimated energy and costs savings associated with your replacement program. Calculate the simple payback of the projects.

6. Comment on whether replacing existing bulbs and fixtures with LEDs makes sense in every circumstance. Why or why not.

Summarize your lighting assessment in a short report, referenced and show your calculations.
