Why are LED lights being used in hospitals?

Earlier, the preferable light source for hospitals was fluorescent and incandescent light fixtures.  As the LED technology arrived, healthcare facilities started replacing their dull flickering lights with warmer, human-focused and power-efficient LED lights. These light sources allow medical facilities to provide not only better services to their patients, but also enable them to minimize their energy costs and maintenance costs considerably. It allows hospitals and all other health care facilities to focus more on offering improved services to people instead of spending on bulbs.

LED hospital lights come in many shades of white, which are referred to as the CCT or correlated color temperature with Kelvin as the measuring unit. As the CCT on the Kelvin scale differs, the lights offer illumination in different colors. Some of the different scales of Kelvin and the color of illumination a LED light fixture offers include:

1. The light will be yellow or orange when the CCT lies between 2000 Kelvin and 3500 Kelvin

2. The light will be natural or neutral white when the CCT scale lies between 3500 Kelvin and 5000 Kelvin

3. Users will get bluish-white color light between 5100 Kelvin and 20000 Kelvin

While in the first case the light will look warm white or ultra warm, in the second case the lights will offer paper white illumination.

Hospitals and healthcare centers need to provide their staff and patients with cool white illumination. Hospital lights that come with this specification will offer several health benefits not only to patients but also to their nurses, doctors, and medical attendants. These benefits include:

  • Decreased fatigue
  • Reduced depression
  • Modulated circadian rhythms
  • Improved alertness

Childcare Hospitals that use an LED light fixture can treat a variety of infant conditions, including hyperbilirubinemia, effortlessly and comfortably.  Further, the availability of windows in the place of work and the presence of daylight have been related to amplified satisfaction with the work setting.

Although windows are the best sources of getting daylight, cool white LED lights that come with the right CCT will offer the same beneficial effects as those of natural daylight. Additionally, the lights that come with warmer color temperatures can release the sleep-causing hormones, known as melatonin. It is suitable for patients to have a sound night's sleep but not appropriate for doctors and nurses performing night duties.

How LED OT Lights are Revolutionizing Operating Theaters?

When it comes to healthcare, efficiency is paramount. Every decision made within a hospital setting, from equipment selection to procedural protocols, is carefully scrutinized to optimize patient care and outcomes. One crucial aspect of this optimization lies in the illumination of operating theaters, where precision and clarity can mean the difference between success and failure. This is when LED OT lights come into the picture. It is the cutting-edge solution with Skynexx that is revolutionizing the way surgeries are conducted. The Evolution of Operating Theater Lighting Traditionally, operating theaters relied on conventional lighting sources such as incandescent or halogen lamps. While effective to some extent, these lighting options came with their fair share of drawbacks. They consumed significant amounts of energy, emitted a considerable amount of heat, and often required frequent bulb replacements, leading to downtime during critical procedures. The Rise of LED Technology In r...

What are LED OT lights in an Operation Theater?

Doctors require a light over patients while they are operating on them to avoid any complications during surgeries. For this purpose, all hospitals use unique surgical lights, i.e., OT lights. They cannot use regular LED lights as they create heat which harms patients. The specialty of OT lights is they provide adequate brightness without heat generation. Additionally, the light diffusion in surgical lights is more than the regular ones. Its illumination ranges from 160,000 to 40,000 lumens. However, the light's lumen also depends on the dome type. For example, multiple domes surgical light would require more power and lumens. Typically, the installation of OT lights is at the ceilings of the Operation Theatre room above the surgical table. So, light falls directly upon patients when doctors operate on them on a surgical table. As a result, they can inspect and conduct surgery better.   Benefits of surgical lights: Increased whiteness that enhances visibility Prevents the emi...
