LED Lighting Case Study – France

LED home lighting


Sitting Room of A Family

(France) This case is about sitting room of a family in France, the house owner wanted to install some new light bulbs all around the sitting room. These lights will be mainly used for general lighting. The owner considered incandescent lighting and fluorescent lighting, but both of them were denied since they were not energy efficient and eco-friendly enough. And EU has planned to phase out incandescent lights, so they decided to find a new type of lighting which is not only energy efficient, but also eco-friendly. Finally they decided to employ LED lighting.

Since the existing fixtures are down lighting fixtures, and the owner did not want to replace them, LED down lighting solution will be the optimum option for him. He developed a set of requirements for any potential solution. He wanted a solution that would meet or exceed the light output and light quality of incandescent and fluorescent lighting. And he wanted a solution that could be easily installed without having to replace the existing fixtures.

After communicating with FOBSUN sales person and engineers, they determined to use FOBSUN LED lighting solution, and FOBSUN FCL-D9076-9W-H LED down lights were chosen as the final solution.

Installation
The house owner installed around 10 pieces of FOBSUN FCL-D9076-9W-H LED down lights in the sitting room as shown in the table below. The table also shows the hours of operation for each installation.

#    Incandescent Wattage    Location          Hours/year
10    60w                             Sitting room    4380 hours

Business Case Analysis
The house owner conducted an analysis to determine the economic feasibility of using FOBSUN LED lighting. This analysis considered several factors including,

Energy savings
Capital cost
Maintenance savings
Reduction of hazardous materials

Energy Savings
Energy savings was the original driver for this project, and the savings were expected to be significant using the latest LED lighting technology. Compared to incandescent bulbs, each of the FCL-D9076-9W-H LED down light consumes 9 watts. Using the hours of operation and incandescent wattage from the table above, the energy savings are as follows:

Incandescent lamps: 2628kwh/year
FOBSUN LED down lights: 394.2kwh/year
Savings: 2233.8kwh/year

The house owner pays $0.17/kwh for its electricity yielding an annual savings of $379.746.

Capital Cost
The capital cost of the LED down lights for this project was $400.

Maintenance Savings
The long service life of the FCL-D9076-9W-H LED down lights eliminates the maintenance cost associated with changing light bulbs (the replacement bulb cost and the associated labor). The approximate maintenance cost savings is $150/year using very conservative estimates for the labor and lamp costs.

Payback
Using the estimates above, the calculated time to payback for this project is slightly more than 0.7 years. Using only the energy savings, the time to payback is slightly more than 1 year.

Future Plans
The house owner is very pleased with the light quality and the appearance of the FCL-D9076-9W-H LED down lights, and has identified additional applications for the products in order to increase energy savings.
