When looking for LED lights to use in dentistry or medical applications you should consider more than just aiming for maximum light intensity. Having the right light at the right spot is vital both in terms of good vision and protecting your eyes from glare and harmful light. Loupes and light are interdependent and choosing the right headlight solution is almost as vital as choosing the optimum eye loupe solution.

When choosing ExamVision as your eye loupe and light supplier, your local dealer will arrange a thorough introduction on how to get the best results. Your loupe will be customized to match your working distance, height and ergonomic needs, and you will be guided in how to attach and focus your LED headlight to achieve the maximum benefit. So, contact your local ExamVision dealer for advice and guidance when choosing both loupe and light to fit your optical needs perfectly.

In all ExamVision loupe lights, we use “neutral white” (≤5.000 to ≤6,500 Kelvin) LEDs for the most natural lighting possible. When considering LEDs with higher Kelvin (more blue light) than the ExamVision Focus™ and Essential range, remember that this means consequently higher lux (or foot candles), but it also means more unnatural light, eye strain – and risk of retinal damage.

Our precision-engineered ”Connect” system fixes the LED headlight to your loupes, sliding smoothly on and off, and maintains the light in a stable manner. A locking mechanism allows you to keep the light permanently attached to your loupe, if required.

Lux (lx) is used for measuring the light intensity or brightness of a light source. There is a general perception that the higher the lux, the better the light. But this is not the case. The maximum lux-level of most LEDs (in the centre of a light, often called hot-spot) is around 30 or 40,000 lux, often measured 20-25 cm from the LED diode. But the real challenge is to get the right quantity of light at the right place in a real working situation. Because, too much light can create glare and damage your eyesight if being exposed to it over longer working hours. Obviously, too little light is just as bad.

Lumen (lm) also indicates the total amount of light emitted from a light source, where Lux is used to measure the amount of light output in a specific area. In other words – 1 Lux is the same as 1 Lumen per square meter.
In general, a loupe light intensity around 10-20,000 lux at an average working distance of 35 cm – evenly distributed across the beam – is perfect for most dental procedures. Glare (from reflective surfaces) is reduced, protecting your eyes, and the LED headlight fitted to the loupe will, together with the normal clinic/background light, be fully adequate to achieve a good and clear vision. Medical procedures in body cavities will often require higher lux, plus a surgeon is often standing, so the working distance is longer. When purchasing an ExamVision magnifying loupe and LED light solution our experts will help you find the perfect fit taking into consideration all your professional needs.
