The bright and consistent lighting is typically focused on the place where the surgery is initiated, giving an ample amount of light and visibility to the surgical team.

These lights can be categorised by the type of the lights – conventional or LED lights. The traditional lights that are filled with gas include halogen at a definite pressure setting. On the other hand, the LED lights are considered to be a revolutionary improvement in the field of surgical lighting. The issue of infrared radiation caused due to excessive heat is virtually eliminated with this LED light.

Additionally, you can choose your examination lights based on how they are mounted – ceiling, wall-mounted or an on-floor or portable solution. Your selection will depend upon your need, your usage and your application.

What are the Benefits of Using Medical Examination Lights?

Unlike traditional lights, these technology-oriented medical lights are beneficial in many ways.

  • Brighter white colours
  • More energy-efficient
  • More accurate colours
  • Emits no heat virtually
  • Lasts much longer

What to Consider Before Purchasing the Examination Lights?

#1 Beaming Heat

The higher levels of heat in conventional lights create discomfort for the surgeons. Moreover, this heat tends to dry the exposed tissues which can potentially impact the care and recovery time of the patient. LED surgical lights are considered to be a good investment as they produce no heat virtually as compared to traditional lights that dissipate much higher levels of heat.

#2 Shadows and Glare

Shadows can spread from the surgeon’s head, arm or the entire body along with the surrounding medical team that is present during the surgery. These LED lights can virtually eliminate the shadows by cross-focusing while using multiple light sources.

Similarly, it can even create a glare – be it from the light source or from other surfaces that are illuminated due to the presence of surgical lights. The presence of glare can cause eye fatigue as well as momentary vision blurring. Hence, you need to be careful while setting the angles of the lights as well as deciding the placement of the reflective surfaces to avoid any type of glare.

#3 Surgical Light Field Diameter

The surgical lights that you are planning to incorporate in your operating room must have the ability to adjust to a wide range of light fields.  Depending upon your need, it should provide you with the facility to change the light focus as per the need. The light intensity should be maximum where the surgeon is operating. Hence, it should provide the convenience of adjusting the light field diameter, as required by the surgical team.

How Will You Integrate Examination Lights into Operation Room?

Choosing your medical examination lights should depend on some important factors including:

  • Space utilisation
  • Human ergonomics
  • Technology
  • Audiovisual equipment
  • Electrical system

To ensure patient care, medical staff satisfaction and return on investment, it is imperative for you to choose the lights that have the facilities of mobility, portability and the right accessories.

  • Quality of the optics as well as light intensity to assist you during any surgical operations
  • The light head is versatile in nature as this will help you evolve with the changing technologies
  • Lighting system must meet the clinical objectives
  • Operating cost of the light head on a daily basis
  • Improvements in efficiency and operating costs, which comes with improved lighting technology
  • Warranty length

Conclusion

With the advanced and upgraded medical examination lights, the medical facilities have gained great support in carrying out the complex surgeries with ease. As and when medical science will progress, you will definitely observe the evolving surgical lighting requirements and specifications that will be all the more helpful to you while carrying out all types of surgical work.
