LED Lighting Case Study – Operation Room of A Hospital in Belgium

(Belgium) Lighting is very important for doctors and patients in a hospital. The right lighting solution can be helpful to the doctors to improve the success ratio of the operations and facilitate the patients to recover rapidly. When the doctors do operations, they need bright lighting which is not too sharp but comfortable. Meanwhile the patients also need comfortable lighting which can ease their mood. Traditional lighting such as incandescent lighting or fluorescent lighting is wide beam lighting type which can not concentrate the light. In addition, incandescent lighting is too sharp and fluorescent lighting contains toxic materials. Incandescent bulbs are energy swallowing monsters and compact fluorescent lamps are not energy efficient enough. A hospital in Belgium was trying to find the best lighting solution for its operation room to replace the existing fluorescent lamps.

Operation Room of A Hospital in Belgium


The hospital contains a variety of lighting technologies, notably a significant number of traditional fluorescent tubes used in the operation room. Given the toxic materials that the fluorescent lamps contain and the flickering light that they output, these lights were prime candidates for upgrades. The doctors initially identified around 14 pieces of grille lamp with 2 pieces of 40 watt T8 fluorescent tubes for each lamp across the ceiling of the operation room.
 
As the doctors considered possible LED lighting options to replace the existing lights, they developed a set of requirements for any potential solution. They wanted a solution that would meet or exceed the light output and light quality of the existing lights and they wanted a solution that could be easily installed.
 
Trial Installation
The hotel considered all kinds of LED lights, many of which they deemed not suitable for their use. A set of selected products were installed in working fixtures across the ceiling of the operation room, and the hospital collected opinions and rankings from all the doctors. They also measured light levels for each installation.
 
The local electricity supplier calculated energy use and savings for the various options being tested. Based on these calculations and the inputs from the various stakeholders, the FOBSUN 300*1200mm LED panel light was chosen to replace the grille lamps.
 
Installation
The hospital installed 14 pieces of 300*1200mm LED panel lights on the ceiling of the operation room as shown in the table below. The table also shows the hours of operation for each installation.

Business Case Analysis
The hospital conducted an analysis to determine the economic feasibility of replacing the existing fluorescent lighting with FOBSUN LED lighting. This analysis considered several factors including,
 
Energy savings
Capital cost
Maintenance savings
Reduction of hazardous materials
 
Energy Savings
Energy savings was a very important driver for this project, and the savings were expected to be significant using the latest LED lighting technology. Each of the 300*1200mm LED panel lights consumes 48 watts. Using the hours of operation and fluorescent wattage from the table above, the energy savings are as follows:
 
Fluorescent tubes: 9,811kwh/year
FOBSUN LED panel lights: 5,887kwh/year
Savings: 3,924kwh/year
The hospital pays $0.17/kwh for its electricity yielding an annual savings of $667.
 
Although not included in the analysis, the use of LED lighting also significantly reduces the heat produced by the light fixtures thereby reducing the load on the air-conditioning system and further reducing the electricity usage.
 
Capital Cost
The capital cost of the LED panel lights for this project was $2,100.
 
Maintenance Savings
The long service life of the LED panel lights eliminates the maintenance cost associated with changing light bulbs (the replacement bulb cost and the associated labor). The approximate maintenance cost savings is $1,000/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 1.2 years. Using only the energy savings, the time to payback is slightly more than 3 years. As a matter of fact, benefits of installing these LED panel lights are far more than just energy savings. More lives will be saved and more patients will be cured due to these LED panel lights, which will greatly improve the reputation of the hospital.
 
Future Plans
The hospital is very pleased with the light quality and the appearance of the LED panel lights. They did the installation manually and final result is perfect! They are quite satisfied with the result of lighting and design.
