Today's surgical headlights offer a wider variety of options like adjustable brightness, fit, comfort and mobility than ever. Newer LED and xenon bulbs produce more light while using less energy.The intensity of illumination systems varies from less than 10’000 Lux to over 200’000 Lux, which is even more intense than the sunlight on a clear summer day. In addition to alternatives in the light source, surgical illumination is now often paired with headlight video imaging equipment and magnifying Loupes.
It is a great challenge to select the right light technology in combination with all the other devices. Halogen bulbs, Xenon bulbs and LED bulbs... There is so much variety to choose from. To develop a better understanding of the pros and cons of this options continue reading on our website: www.integratedsurgialsolutions.com
Halogen bulbs– traditional yet effective! While technically a form of incandescent lighting, halogen bulbs are in many ways no match for LEDs. These bulbs have a rated lifetime of 1,000-1,250 hours.On the upside they emit crisp white light ideal to perform surgical procedures. They are cost effective and efficient. Many Outpatient Surgery Centers and Veterinary hospitals use halogen powered surgical lights during procedures. Halogen Bulbs produce heat that can be felt by the surgeons, often contributing to fatigue.
Xenon Fiber Optic Lights
Traditionally Surgical Xenon Headlights use a separate light source with about a 7 to 10-foot fiber optic cable attached to the light on the surgeon’s head. Xenon Headlights have not evolved over the last 10 years. The technology uses the noble gas xenon to produce high light output, a stable and warm color temperature and a full spectrum lighting that matches natural sunlight. 300W Xenon lamps are perfect for medical applications where precise nuances of color truly matter. Xenon bulbs accurately portray colors and have a perfect color rendering indexes of 100. This is essential in diagnosing. Xenon bulbs don't produce as much heat as other bulbs and emit minimal UV rays. This feature makes these bulbs safe to use.
In 2005, Enova® Illumination introduced the first surgical headlight using LED’s as the light source. Since then LED technology has all but replaced Fiber Optic Xenon systems as the preferred head mounted surgical light. LED’s (Light-emitting diode) use a diode about one-fourth of an inch to convert electricity into light. One huge benefit to using LED’s is its energy consumption of about one-seventh of that of an incandescent bulb. The lamp Live ranges from 50,000 up to 100,000 hours. When choosing surgical lighting, it’s vital to find a system that balances color temperature with color rendering index (CRI) and brightness. CRI refers to how closely a light shows the true color of what it’s illuminating in comparison with a natural light source. A rating between 85 and 98 results in excellent rendition. (The highest possible CRI value is 100, and would be given to a source identical to standardized daylight.)
In the last few years there have been some major advances in the world of LED lighting. The technology has gone from being a unique novelty to becoming a very useful tool for surgeons in the operating room. Some key features for surgical use are cooler temperature, adjustable brightness, true rendition and light intensity of up to 225’000 Lux with the new Enova XLT-225.
Going Green: With a longer life expectancy, which helps keeping bulbs out of landfills, no Mercury and low energy consumption LED technology does its part in helping the environment.
There have been a lot of technology changes in surgical headlights over the years but it certainly looks like LED headlights are here to stay and will continue to get better.
