Are single arm or multiple arm ceiling mount lights the best option?
This question is a bit difficult to answer as a general statement since different types of surgical procedures may require highly focused lights from multiple angles. In general a single arm version of operating room light and OR lights is a great option, however it may not be all that is needed. Multiple arms on the same track or trolley in the operating room allow the light source to be directed from multiple points, giving the most comprehensive lighting.
Multiple arm operating room light and OR lights are also typically more space saving than having a single arm ceiling mount and lamp or stand type lights for additional lighting when needed. Stand types of lights can be difficult to store plus they do need to be carefully positioned around a surgical table to avoid restricting access to the patient by the staff.
What types of bulbs are used in operating room lights and OR lights?
There are several different options when it comes to operating room lights and OR lights with regards to types of bulbs. It is important to realize that bulbs and lights are uniquely matched and it is not possible to switch bulb types within fixtures, unless explicitly approved by the manufacturers of both the bulb and the fixture.
Most specialized types of lights used in operating rooms and OR rooms will be halogen, halogen-xenon, metal halide or LED types of bulbs. LED lights are generally used for spot type focus while the other types of bulbs may be used for wider lighted areas and even entire surgical and operating rooms. Combining different types of specialized fixtures and bulbs within a room is also a possibility to provide the brightest, truest light available.
What is an important feature to look for in operating room light and OR lights?
One very important consideration when selecting operating room light and OR lights is the maintenance factor. Lights for the OR are designed with smooth surfaces for easy cleaning and disinfecting, which includes protecting the bulbs but also in the actual fixture design itself. Operating room light and OR lights also have to be designed to allow easy to change out bulbs. Many fixtures now offer options to change out bulbs without the requirement of specialized tools, making maintenance much less complicated than the older models.
It is also important to consider the lifespan of the bulbs as advertised by the manufacturer. Some of the newer spot types of LED lamps used in both flexible positioning surgical lamps as well as ceiling mounted fixtures can last an amazing 50,000 hours, which translates to about 5.7 years of use for each and every bulb.
Halogen types of bulbs also have long lasting lifetimes of up to 2000 hours, plus they also have the ability to provide very specific lighting sources ideal for the demanding lighting needs in an operating room as well as a patient examination room.
