For dental professionals, the need for an effective lighting solution is paramount. Eyestrain is a common problem; by having to concentrate on a fixed point inside the oral cavity for long periods of time, or by constantly adjusting their sight to the different ambient lights in and outside the oral cavity, dental professionals increase their chance of suffering from aesthenopia.

For years, practitioners have tried to combat this issue with effective lighting. By utilising high-quality products, professionals can not only reduce the risk of eyestrain, but improve the accuracy and consistency of their clinical work.

Traditionally, dentists have used halogen lights to illuminate their patients’ oral cavities; indeed, many still do – but increasingly, these halogen systems are being replaced by LED alternatives. Light emitting diodes have become more and more popular across a wide range of different fields and environments in recent years – from domestic living to clinical and scientific settings – and they do have a number of compelling advantages over other light sources.

1. Longevity

LED lights have an outstanding operational lifetime expectancy – approximately 100,000 hours. This equates to around 11 years of continuous operation. In other words, if an LED light is left on for around 8 hours a day it would take about 20 years before the ‘bulb’ would need replacing. In a dental surgery, where the clinical light would only be used during appointment times, the potential longevity of a single fixture is incredible.

2. Energy efficiency

Compared to traditional lighting, LED lights are exceptionally efficient. Estimates suggest that high-quality lights are approximately 80-90 per cent more efficient, meaning that almost all of the electricity expended on powering one is converted to light. Only the remaining 10-20 per cent is lost and converted to heat. This will ultimately save a dental practice a significant amount of money on electrical bills and, when considered alongside the life expectancy of a single LED fixture, the savings can be substantial.

3. Ecologically friendly

Unlike many other fluorescent light sources, LED lights are completely free of toxic chemicals. As such, they can be easily recycled[1] and enable a dental practice to dramatically cut its carbon footprint. Again, thanks to their exceptionally long life expectancy, an LED light can save the material and production of at least 25 incandescent light bulbs.

4. Durability

LED lights are also extremely durable when compared with more traditional lighting solutions. They are particularly resistant to shock and vibrations which, in a dental scenario, can offer real peace of mind.

5. Instant lighting

When switched on, an LED light will brighten immediately. This helps save time when performing a dental examination and improves efficiency.

6. Frequent switching

Unlike other light fixtures, LED lights are not negatively affected by being switched on and off frequently. In the dental surgery, where a light is being turned on and off many times throughout the day, this is an important consideration.

7. Low-voltage

A low-voltage power supply is more than sufficient to power an LED light, which is excellent for safety and more cost effective than other alternatives. 

8. Quiet and cool

Thanks to their aforementioned energy-efficiency, LED lights do not produce a great deal of heat. This is not only safer, but also eliminates the need for an integral fan, meaning the whole fixture is quieter during operation. This is a great help for anxious patients, who may be discomforted by the sounds of a dental surgery – and is also less annoying for practitioners who must be around their light for long periods of time.

9. Design flexibility

LED lights can be combined in a dynamic range of shapes to produce highly efficient and adaptable illumination solutions – and can offer incredible amounts of control. A well-designed fixture can achieve highly effective, focussed lighting that will allow a dental professional to have complete visual freedom during an examination.

LED lights are becoming increasingly popular on the UK dental market as their advantages are being recognised. It is always best, however, to compare competing brands to ensure the right choice is made – since an LED light will last for the majority of a dentist’s natural career. A light that is ergonomic, effective and easily positioned is ideal, as is one that can be easily integrated into an existing space with little disruption or difficulty.

The LED light from A-dec, for example, is a high-quality lighting solution that adds fluid manoeuvrability, improved lighting for better shade analysis and delivers 25% more illuminance at one fifth of the power consumption.
