Light for Watchmakers

General information for lighting watchmaker workstations

Properties

A watchmaker must be able to recognize the smallest details and colours to do precise work when testing, repairing and maintaining watches or manufacturing horology instruments.  To meet the high-quality demands of its customers and to be able to work precisely, he needs not only a steady hand but also a light, that is specially designed for his individual needs. Overall room lighting, natural daylight or conventional luminaires generally don’t suffice the lighting needs of such a filigree craft. Besides, there is an increased risk of accidents and a negative impact on health if the light at the workstation is inadequate or poor. Therefore, it is crucial to know where to look when choosing your task light. An important reference point here is the corresponding guidelines and DIN standards for the lighting of watchmaker workplaces which should always be met.  In the following, we will show you the most important features and characteristics of good light for the watchmaker to help you in your choice of the right lighting.

Illuminance & Colour Rendition

Illuminance describes the ratio of luminous flux to the illuminated surface. With increasing illuminance, visual performance also rises so that contrast and contours can be better seen. We, therefore, recommend an RMD light with illuminance in the range of 2800 to 3300 lux for the precision mechanical work of a watchmaker, such as a dial assembly, replacement of individual parts or quality control. Additionally, the light should have a balanced luminance distribution to avoid disturbing shadows and illuminate not only partial areas but also the entire workplace at the same time. To ensure exact colour visibility, it is advisable for you to have a luminaire with a colour rendition index of CRI > 90 for final inspection work and CRI > 80 for all other tasks.

Glare

At least as equally important for watchmakers is a glare-free and flicker-free light when working with shiny pieces. Dazzle can limit our recognition and can have a negative impact on the user’s health. Therefore, luminaires with optimum glare control, adapted luminance distribution and good glare protection are a prerequisite when illuminating a watchmaker’s workstation to ensure the trouble-free performance of the visual task. To avoid any reflection glare when working with shiny parts, the LEDs of RMD workplace luminaires for watchmakers are covered with an opal white screen.

Flexibility

Thanks to innovative articulated arm technology, the lamp can be easily adjusted to suit the watchmaker’s activities and offers a wide range of movement in different situations.  In this way, the watchmaker can move the luminaire to the desired position within a few seconds, depending on the application requirements and daylight hours. Additionally, he can adjust the illuminance individually by means of a dimmer switch to achieve optimum lighting conditions anytime.

RMD Task-Lights

Our workplace luminaires are designed specifically to support the visual task of a watchmaker. They meet all the requirements a watchmaker sets for lighting quality and create a pleasant lighting atmosphere. With state-of-the-art LED technology, the latest reflector technology, and ergonomic lighting design, our RMD Task-Lights are flexible and can be individually adjusted to the visual task each watchmaker performs. In this way, optimal light and a balanced brightness distribution can be achieved always. In addition, a high colour rendering, high luminous efficacy, and optimum glare protection enable you to recognize contrasts and colours precisely so you can work reliably without restrictions. Focused on the needs of a watchmaker, we want to provide fatigue-free working and a pleasant working atmosphere using our RMD workplace luminaires.

Economical Aspect

With an intelligent lighting design, high-quality materials and the use of state-of-the-art LED modules with a service life of up to 50,000 hours, our RMD workplace luminaires can help you to reduce your energy balance and save high costs. A high protection class ensures a low maintenance effort and reduces service intervals.

In summary, the most important quality features resulting from the DIN standards and guidelines for the lighting of watchmakers’ workplaces are listed again below.

Quality Requirements

  • Strong, large-area light, illumination at least 1500 lx, better 2800 lx to 3300 lx
  • Colour temperature > 5000 Kelvin, better daylight from 5300 Kelvin
  • Colour rendition CRI > 80 or CRI > 90 for quality control
  • Glare- and flicker-free light

  • No stroposcopic effects
  • Balanced illuminance distribution

Recommendations

Our RMD workstation luminaires are recommended as follows. They consider specified quality requirements and represent the best-selling products sold to our watchmakers. The recommendations given are only articulated luminaires. Of course, if you have enough space in your workplace for a pendant lamp, this option can also be used. Of course, you can have a look at other RMD workplace luminaries and if you have any questions, please do not hesitate to ask us.
