The Cesar Opera DO is a drive-over in-ground luminaire specifically designed for urban environments, residential settings, and public parks where both pedestrian and light vehicular traffic are present. Engineered to combine strength, versatility, and visual appeal, it offers reliable illumination in demanding outdoor conditions while maintaining a refined architectural presence.
This round in-ground luminaire is available in four different sizes, ranging from small to extra-large, making it adaptable to a wide variety of project requirements. Customers can choose from five standard finishes, including stainless steel, grey, anthracite, black, and white, ensuring seamless integration with surrounding surfaces and architectural styles. The luminaire provides multiple light distributions, such as wide diffused, narrow beam, medium beam, and asymmetric beam, to suit different design needs. Optical flexibility is further enhanced with tilt options, allowing adjustments of ±15° for narrow and medium beam settings and ±5° for asymmetric beams.
In terms of lighting performance, the Cesar Opera DO is offered in three standard color temperatures—2700K, 3000K, and 4000K—all with a high color rendering index (CRI 90) to deliver natural and accurate illumination. It is available with either non-dimmable or DALI-2 dimmable control, with remote driver options for the small and medium versions, while the larger sizes integrate DALI-2 drivers directly. This flexibility allows designers and installers to match the lighting control to the needs of the project, whether simple on/off switching or integration into advanced lighting management systems.
The luminaire is built to withstand demanding conditions, with a load-bearing capacity of 5,000 kg at speeds up to 30 km/h, making it suitable for vehicle passageways and drive-over applications. Its robust construction includes a die-cast aluminum housing, A4 stainless steel bezel and screws, clear toughened glass, silicone gaskets, and a double powder paint process for enhanced durability. The polypropylene recess box further supports long-term reliability. The luminaire is rated for C3 corrosion resistance according to ISO 9223:2012, ensuring suitability for standard outdoor environments.
Installation is straightforward, with each size supplied with a recessed mounting box for secure in-ground fitting. Pre-wired cables are included, with cable configurations varying depending on luminaire size: the small and medium sizes offer pre-wiring up to 0.5 meters with HF and RD options, while the large and extra-large models are also pre-wired with a 0.5-meter lead. For small and medium sizes requiring dimming, a remote DALI-2 driver must be ordered separately.
For specification, the luminaire is defined as a round, recessed, drive-over in-ground light suitable for vehicular traffic and pedestrian use. Available in four sizes and multiple finishes, it provides intensive, extensive, medium, and asymmetrical light distributions depending on size selection. With tiltable optical modules for precise beam adjustment (except on extensive beam versions), color temperature options of 2700K, 3000K, and 4000K with CRI 90, and dimming options from integrated or remote DALI-2 drivers, it is an adaptable solution for both residential and public applications.
Engineered for strength and longevity, the Cesar Opera DO achieves IP67 ingress protection and IK10 impact resistance, ensuring full protection against dust, water, and mechanical stress. This combination of durability, lighting performance, and flexibility makes it an ideal solution for contemporary outdoor projects where safety, reliability, and architectural integration are critical.
