LED light bulbs and fixtures are the best alternatives for many reasons.

LED lights are available in several shades of white. These shades are referred to as a bulb’s correlated color temperature (National Institute of General Medical Sciences, states that, “Circadian rhythms are physical, mental and behavioral changes that follow a roughly 24-hour cycle, responding primarily to light and darkness in an organism’s environment.”

According to writes, “Several studies have documented the importance of light in reducing depression, decreasing fatigue, improving alertness, modulating circadian rhythms, and treating conditions such as hyperbilirubinemia among infants. Further, the presence of windows in the workplace and access to daylight have been linked with increased satisfaction with the work environment.” Windows are the best method of accessing daylight, but cool white LED lights along with the right color temperatures at the right times, can have the same effect on the body.

Warmer color temperatures lead to the release of melatonin, which causes drowsiness. This is appropriate during bedtime hours, but causes problems for those who need to stay awake, such as overnight nurses and doctors. Introducing natural or cool white light to hallways, operating rooms, and nurse stations can help hospital staff, especially overnight workers, feel more alert and energetic.

EPA has a list of cleanup procedures, such as having everyone leave the room, opening a doors or windows, shutting off heat and air-conditioning systems, and other specific instructions.

Fluorescent and incandescent bulbs also emit low doses of UV radiation that can damage not only facility materials but can also damage skin and eyes. According to a CBSLA.com discusses the results of another study that had similar findings. In this article, it is said that, “. . . exposure to the (fluorescent) bulbs could lead to premature aging and cancer.”

Continued UV exposure is also harmful to the eyes. A LED lights won’t flicker or emit any color spikes. Color fluctuations and flicker can cause negative effects, such as headaches and dizziness. When used for hospital lighting, LED bulbs and fixtures can improve overall health and eliminate the possibility of additional health risks posed by fluorescent and incandescent bulbs.

Seeing colors as they truly are is critical in health care environments. Inaccurate color rendering of skin or blood could lead to a misdiagnosis or failure to see signs of infection or jaundice. The spectral graph below can be helpful in understanding the advantage of high-CRI light sources. Lights with a low CRI will show fewer colors while high-CRI lights cover more of the spectrum. A light source’s ability to show more colors increases its accuracy in revealing the true colors of people, objects, and surroundings.

FreemanWhite, a health-care-focused design firm reports, “. . .light fixtures with a high CRI . . .  help caregivers assess rashes, lesions, and skin pigmentation.” They go on to say, “In the interest of avoiding liability claims, better lighting quality can enhance a caregiver’s ability to diagnose correctly, identify reactions, prevent secondary infections, and minimize readmissions.” High-CRI LED lights can also help prevent medication errors.

Another method of LED hospital lighting control is the use of occupancy sensors. These sensors will save money beyond those that result from reduced energy consumption. Sensors will also extend the life span of bulbs and fixtures even further by turning them off when no one is in the area. These sensors are best suited for low-traffic areas.

Lights are one of the greatest things about the holidays. You’ll find them in trees, colorfully decorating home exteriors; you’ll even find them on vehicles. And honestly, we love it. Lighting is one of the keys to the spirit of the season and an integral part to this time of the year. But, as we’re all well aware, they aren’t exactly the easiest thing in the world on your energy bills.

The term “light box” can mean a few different things, but from a lighting perspective it typically refers to a backlit display panel. Light boxes are most commonly used for advertisements or other commercial displays. You’ve probably seen them in trade show booths, restaurants, airports, nightclubs, offices, hotels, museum exhibits, and retail shops. That’s right, light boxes are everywhere.

One of the most common uses for light boxes is the commercial advertisement. You see these in large spaces like terminals or outdoors at bus stops. They capture the attention of passers-by and create lasting impressions. The light box pictured below is one of the biggest I’ve ever seen.

One of the most obvious places you’ll see light boxes are along the walls inside and outside of movie theaters. Sometimes lines of light boxes stretch incredible distances, advertising all the movies being shown in large theaters.

In fact, light boxes can be a fun addition to any home and can be used for as many purposes as you can imagine. Sure, you could illuminate a movie poster of your daughter’s favorite movie. But you could also make a custom sign saying whatever you want. I really like the light box below, created at home for home.
