As hospitals operate 24/7, a significant reduction in lighting costs would be extremely beneficial. LED bulbs require much less power to achieve an equivalent amount of light to incandescent bulbs. In addition, because LEDs emit very little heat, it does not place extra stress on air conditioning units. In a hospital environment where hallway lights and patient room night lights are running round-the-clock, a return on investment can be achieved within 6 months.
Mercury is a serious workplace hazard, and hospitals that use CFL bulbs are constantly risking patient exposure to the harmful effects of mercury. Hospitals require a certain standard of lighting not only to provide the best care for their patients, but to provide a comfortable environment for both employees and patients.
Surgeons, for example, require a high quality light, of the right color temperature and output, that doesn’t produce glare or shadows. Lights that do not generate heat are also important for both the comfort of the surgeon and the safety of the patient (as high heat can dry out tissue).
Not only do LEDs meet all these requirements, but the ability to dim is extremely useful in certain applications, such as MRI rooms. Dimming also provides a more soothing environment for patients. Many hospitals are beginning to invest in LED lighting for all the above benefits and more.
