Nowadays surgical LED lights have proven to be the superior option to traditional halogen lights. As a result, they continue to be the preferred replacement for their halogen counterparts. While the initial investment might sometimes seem rather large, they offer numerous benefits lead to solid returns in performance, surgeon accuracy, and health. Some industry experts suggest surgical LED lights could completely replace halogen lights by the end of 2015.
A primary reason LED lights are preferred is because they create a pure white color. Traditional light bulbs cast a yellowish hue over everything. The only way to correct the hue traditional light bulbs create is by adding a coating to offset this. Unfortunately, the coating significantly increases the temperature of the light bulbs. This additional heat eventually permeates throughout the room. Plus, while the bulbs emitted a whiter light, it is not actually white. In fact, if you put two bulbs directly next to each other a discerning eye will quickly be able to tell them apart. This can be become incredibly distracting during surgery and can hurt a surgeon's concentration during long procedures. An LED light can produce the preferred color temperature without any coatings.
Another reason surgical LED lights are a better solution is because they are more reliable. Halogen lights rely on a tungsten filament. When it heats up, it starts to go which is how each bulb produces light. Over time, the tungsten filament becomes thinner and eventually breaks which is what causes bulbs to burn out. LED lights rely on a solid state technology. Since there isn't a filament, it can't burn out in the middle of a procedure. An LED light can actually be used more than fifty thousand hours without burning out whereas a typical light bulb only has a lifespan of several thousand hours.
Some people refer to LED lights as natural light. This is because they create daylight-like light. As a result, they create less stress on the surgeon's eye while providing a similar light intensity. This make operating under LED lights much easier on the surgeons eyes, especially when the surgery may last for multiple hours.
Overall, there is no front in which halogen bulbs are advantageous over surgical LED lights. The only its potential benefit is the initial investment cost. Halogen lights are cheaper because they are not designed to last as long. Over the lifespan of a single LED light, the total cost savings will be significantly greater. The key is to keep the long-term costs in perspective.
