Optec by ERCO is a highly versatile spotlight system designed to meet the full spectrum of lighting requirements in shops, galleries, museums, and other exhibition spaces. Whether the goal is high-contrast accent lighting, precise floodlighting, uniform wall illumination, or dramatic effects using sharply defined beams, Optec delivers with performance, precision, and flexibility. Its innovative photometric design merges energy efficiency with exceptional visual comfort, making it a go-to lighting tool for dynamic and changing environments.
The Optec range includes a variety of versions, each tailored for specific lighting tasks. Spotlights with rotationally symmetrical beam angles—from very narrow to wide—are ideal for focused accentuation of objects, artwork, or architectural details. Zoom spotlights introduce another layer of adaptability, allowing the beam diameter to be adjusted seamlessly between 15° and 65° by rotating the lens. This makes them particularly suited to areas with changing exhibits or retail displays, enabling both precise accent lighting and broader washlighting. The zoom spotlights are also available in oval beam variants, which can be rotated 360° for ideal alignment with linear subjects. For even more defined and dramatic lighting effects, Optec contour spotlights use a framing attachment and projection lens to create crisp, hard-edged beams that can give illuminated objects a glowing, from-within effect. These are especially effective when lighting framed artwork or displays that benefit from precise beam shaping.
Another standout capability of the Optec series is wallwashing. When used for vertical illumination, the lens wallwashers should be positioned approximately one third of the room height away from the wall to achieve uniform brightness. At this distance, a tilt angle of around 35° ensures balanced distribution across the vertical surface. For accent lighting and floodlighting applications—such as illuminating sculptures, paintings, or merchandise—the optimal tilt angle is approximately 30°, providing dimensional modeling of objects without introducing harsh shadows or distortion. This tilt angle also minimizes shadows cast by the observer, enhancing visual clarity and engagement.
Optec combines high-performance optics with a practical and aesthetically pleasing design. At the heart of its lighting performance is the ERCO Spherolit lens system, which offers a range of light distributions including narrow spot, spot, flood, wide flood, extra wide flood, oval flood, and wallwash. The lenses in zoom and oval flood variants are freely rotatable, allowing the light output to be aligned precisely to the target object. Additionally, the contour spotlight attachments are fully rotatable and include a framing system with a continuously focusable projection lens, enabling clean light edges for theatrical and exhibition use.
The LED module inside each Optec luminaire consists of high-power LEDs available in warm white (2700K or 3000K) and neutral white (3500K or 4000K), paired with a collimating lens made of optical polymer to ensure tight, efficient beam control. The cylindrical light head is constructed from powder-coated cast aluminium and can tilt up to 270°, while the housing—made of high-quality polymer—is rotatable 360° on the track adapter. Finishes are available in white (RAL9002), black, or silver, allowing seamless integration into various interior aesthetics.
Control options are equally comprehensive, with support for switchable, DALI dimmable, Casambi Bluetooth, and phase dimmable + on-board dim configurations. The phase dimmable variant includes a built-in rotary control for local dimming and is compatible with external trailing-edge dimmers. This flexibility makes Optec suitable for standalone installations or integration into sophisticated lighting control systems via ERCO’s 3-circuit or DALI track adapters.
As an entry-level product with advanced capabilities, Optec offers an outstanding price-performance ratio. It meets essential standards of energy efficiency and visual comfort, while providing the adaptability needed for complex and changing lighting environments. Whether used for accentuating fine art, framing displays with sharp contours, or delivering immersive wallwashing, Optec stands out as a complete lighting solution for professional spaces that demand both function and finesse.
