In general, all of our products are suitable for an illuminance of 30 lux. The key factor here is setting the dimming level correctly. For applications with low illuminance levels, we recommend always selecting the lowest possible wattage.

For individual spotlights, LED drivers with a dimming range of 0.1–100% should also be used to ensure precise and uniform light control.

Our track spotlights are dimmable down to 1% (exceptions: Casambi C1-mini-C and C2-C spotlights). The C1-mini-C and C2-C models can even be dimmed down to 0.4%, allowing for particularly fine-tuned lighting adjustments.

Thanks to our modular system, our products can be flexibly adapted to a wide variety of lighting requirements. They were developed specifically for display case lighting in museums, but are also ideal for use in stores, galleries, and sophisticated interior lighting applications.

We would be happy to advise you personally and help you find the optimal lighting solution for your project.

Yes, our heaters generate heat, the extent of which depends on the specific product model as well as the environmental conditions at the installation site (e.g., ambient temperature, air circulation, and installation configuration).

Yes, only products with a mechanically screw-mounted light head are suitable for this purpose. Due to their design, models with a magnetic ball joint are not suitable for this application. Suitable models include, for example, the C1-micro-VL-D single spotlight and various spotlights for magnetic track systems.

If your project requires UL certification, we'd be happy to advise you on selecting the right product.

PWM dimming (pulse-width modulation) is a method for controlling the brightness of LEDs. In this process, the LED is turned on and off at a high frequency. By varying the ratio of the on and off times, the perceived brightness is adjusted without significantly changing the color of the light.

In general, many of our products can be integrated into existing control systems. Compatibility depends primarily on the power supply or LED driver used. With the appropriate components, our solutions can be integrated into DALI, Casambi, or KNX environments. The C1-mini-C and C2-C models can also be connected directly to an existing Casambi network.

Dimmers from feno GmbH are used with our track spotlights that do not have a built-in dimming function. Dimming is achieved via a PWM signal transmitted through the magnetic track. The dimmers can operate within a voltage range of 10 to 48 V DC and use a low PWM frequency to minimize potential noise.

A potentiometer is an adjustable resistor used to control voltage or signals. Turning or sliding a movable wiper changes the resistance value. In a PWM dimmer control system, the potentiometer serves as a setpoint sensor. Adjusting the potentiometer changes the duty cycle of the pulse-width modulation. The higher the duty cycle, the longer the LED remains on and the brighter it appears. This allows for efficient and stepless control of the brightness.

For digital dimming, we recommend using power supplies or LED drivers from eldoLED. These support various digital dimming protocols and enable precise, flicker-free lighting control. We’d be happy to help you select the right driver for your application.

With the Casambi app, you can quickly and easily pair or unpair compatible devices. If a light has already been connected to another network, you can reset it and then easily integrate it into your own Casambi network.

To set up and control Casambi-compatible products, you'll need the free Casambi app. It's available for iOS and Android devices.

With the Casambi app, you can set up, group, and dim compatible lights, as well as create custom lighting scenes.

Our standard delivery time is 6–8 weeks. However, this can vary significantly and always depends on the size of the order and the specific requirements of the product you wish to purchase.

We always ship our products in accordance with the International Chamber of Commerce (ICC) shipping terms, specifically FCA (Free Carrier). The goods are packaged and made available to our customers for pickup.

New customers are always required to pay in advance. Payment terms may be adjusted as our business relationship progresses.

In general, you can cut our magnetic rails to the desired length yourself. However, cuts may only be made on the side without the mounting hole. Please understand that we cannot accept any liability or provide any warranty for any damage resulting from cuts you make yourself.

Alternatively, we can cut the rails for you: We’ll manufacture your magnetic rails exactly to the dimensions you need for your project at no extra charge.

Magnetic rails are available in gold, champagne, silver, and black.

Unfortunately, we cannot offer magnetic rails in white, as we use RAL-compliant powder coating for our white finish. However, the coating would cause the rails to lose their conductivity.

Unfortunately, powder coating is not possible for our magnetic rails, as it would impair the rails' electrical conductivity.

To accommodate a wide variety of installation scenarios and applications, various mounting solutions are available for our magnetic rail systems.

Depending on your project requirements, magnetic, screw-mounted, or adhesive mounting options are available. We would be happy to advise you on selecting the mounting solution that is technically best suited for your application.

With our puck, magnetic tracks can also be installed vertically.

For our magnetic track spotlights, we offer the special colors gold and champagne, as well as powder coatings in RAL colors.

The C1-mini-HC spotlight can be easily adjusted using the dimming stick included in the package. Insert the dimming stick into the designated slot on the front of the spotlight. A green LED lights up during the dimming process to indicate active communication and confirm the setting.

The C1-micro-LC, C1-mini-LC, C1-mini-UHC, and C1-USTS lights can be dimmed in groups.

The maximum number of lights depends on the power (wattage) of the power supply used. We'd be happy to advise you on this.

Our lenses are not permanently installed and can be replaced as needed.

Diffusion films are used to specifically control the beam angle of the lens.

A zoom lens makes it possible to change the focal length and thus flexibly adjust the beam angle without having to reposition the light fixture.

Elliptical beam angles are produced by our strip lenses (Fresnel lenses).

- C1-nano/micro/mini Series: 40°+10° and 47°+25°
- C1 Series: 46°+10°
- C2 Series: 35°+15° and 12°+50°

We would be happy to provide you with the lighting specifications. Simply use the contact form on our website to request them.

Yes, the mounting flange can be cut to size. You can specify the desired dimensions on the approval form.

Our lenses are not permanently installed and can be replaced as needed.

The number of lights that can be operated depends on the power (wattage) of the respective power supply.

Diffusion films are used to specifically influence and adjust the beam angle of the lens.

Our zoom optics are not suitable for the single-beam fixtures in the C1-mini-E-VL series that come with extension tubes. Due to their comparatively high weight, they increase the mechanical load and may interfere with the secure positioning of the fixture head. For this series, we recommend using the standard optics provided.

These zoom lenses are not suitable for the C1-VL series single-beam spotlights with extension tubes. Due to their comparatively high weight, they may cause increased mechanical stress and limit positioning options. We recommend using the standard lenses in this case as well.

A zoom lens makes it possible to change the focal length and thus flexibly adjust the beam angle without having to reposition the light fixture itself.

Elliptical beam angles are produced by our strip lenses (Fresnel lenses).

- C1-nano/micro/mini Series: 40°+10° and 47°+25°
- C1 Series: 46°+10°
- C2 Series: 35°+15° and 12°+50°

Powder coating in RAL colors is available for the following single spotlights: C1-mini-DL, C1-mini-E, C1-mini-E-VL, C1-mini-S, C1-mini-S-VL, C1-DL, C1-S, C1-VL, C2-S, and C2-DL.

Yes, the mounting flange can be cut to size. You can specify the desired dimensions on the approval form.

Tunable White is available for the R-SL-16 light bar and its variants (e.g., R-SL-16-T and R-SL-16-TG).

The R1 light strip cannot be combined with spotlights. As an alternative, we recommend our R-SL-16 linear light fixture, which can be combined with the C1-mini-R-SL spotlight.

The different beam angles are created by the variable positioning of the linear lens within the profile. Depending on the installation height, the light distribution—and thus the beam characteristics—changes.

With this combination, the heat generated cannot be adequately dissipated. To prevent overheating and potential damage, and to ensure reliable operation, the power is limited to 1 W.

In the “TG” versions, the tubes are mitered, creating a particularly elegant silhouette. In the “T” versions, the transition is achieved using specially designed end pieces.

Yes, we also manufacture both series in custom lengths. Please feel free to contact us.

The R1, R1-T, and R1-T-BS light strips, as well as the R-SL-16, R-SL-16-T, and R-SL-16-V, can be powder-coated.
