L1200/L1500/L3000 Series Optix Linear Light Linkable Indirec

What is the L1200/L1500/L3000 Optix Linear Light and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we engineer architectural lighting solutions for discerning specifiers in the EU, US, and Middle East. The Optix Linear Light series is a premier example of this, offering a highly versatile and efficient linkable system designed for commercial, educational, and retail environments. Available in standard lengths of 1200mm (38W), 1500mm (48W), and 3000mm (96W), the Optix system combines performance with aesthetic flexibility. Its core feature is a sophisticated optical design providing both direct and indirect illumination. A precise 60° downlight beam delivers controlled task lighting, while a wide 140° uplight component washes ceilings with soft, ambient light, creating a balanced and visually comfortable space. This dual-function approach reduces stark contrasts and minimizes shadows, making it ideal for specifications demanding both performance and occupant well-being.

Constructed from high-grade 6063 brushed aluminum with a clean profile of 65mm width and 75mm height, the Optix series can be suspended as individual pendants or linked together to form seamless, continuous runs of light. This modularity gives architects and lighting designers the freedom to create tailored lighting layouts that perfectly align with interior design concepts, from long corridors in hotels to dynamic arrangements over collaborative workstations in modern offices. Standard finishes include matte white and matte black, with custom RAL colors available to match any project palette.

Which spaces is it designed for?

The Optix Linear Light system is engineered for spaces where visual comfort, adaptability, and architectural integration are paramount. Its combination of controlled direct light and diffuse indirect light makes it exceptionally suited for modern workplaces, educational institutions, and high-end retail applications across Europe and the United States.

How does direct/indirect lighting improve visual comfort in an office?

In open-plan offices, meeting rooms, and executive suites, balanced illumination is critical for productivity and well-being. The Optix series directly addresses this by using its 140° uplight to illuminate the ceiling, which becomes a large, diffuse secondary light source. This technique raises ambient light levels, softens shadows, and reduces the cavern effect common with downlight-only schemes. The controlled 60° downlight component efficiently illuminates the primary task plane (desks and surfaces) to recommended levels of 300-500 lux, while the overall scheme maintains a Unified Glare Rating (UGR) well below 19, complying with the EN 12464-1 standard for office lighting.

What is the process for creating continuous runs with the linkable system?

For applications in corridors, large retail spaces, or over long banks of desks, the ability to create long, continuous lines of light is a key design requirement. The Optix system is designed with simple and robust linking mechanisms. Each luminaire section (1200mm, 1500mm, or 3000mm) comes with integrated mechanical and electrical connectors. Installers can quickly and securely join sections end-to-end, creating uninterrupted runs of bespoke lengths. This not only ensures a clean, monolithic aesthetic but also simplifies the wiring process, as multiple luminaires can be powered from a single feed point, significantly reducing installation time and complexity for electrical contractors.

Can this fixture support tunable white for human-centric lighting designs?

Yes, the Optix series is available with a Tunable White (TW) option, making it a perfect choice for human-centric lighting (HCL) specifications in schools, healthcare facilities, and forward-thinking corporate offices. Using DALI Type 8 (DT8) control, the luminaire's color temperature can be dynamically adjusted from a warm, relaxing 2700K to a cool, energizing 6500K. This allows for the creation of lighting scenes that mimic the natural daily cycle of daylight, helping to regulate occupants' circadian rhythms, improve concentration during peak hours, and promote relaxation at the beginning and end of the day.

Installation, control and compliance (DALI-2 / Casambi / 0-10V, CE / RoHS / ErP)

The Optix Linear Light is designed for suspension mounting via adjustable aircraft cables, allowing for precise height setting of both the luminaire and the suspension points. Control is a key strength of the system. The standard configuration includes a high-quality DALI driver from leading brands like Tridonic or Osram, enabling individual or group dimming and integration into building management systems (BMS). It is compliant with DALI-2 for enhanced interoperability. For projects requiring alternative control protocols, we offer 0-10V dimmable drivers. Furthermore, for retrofit projects or spaces where new control wiring is impractical, the system can be equipped with Casambi Bluetooth mesh components for advanced wireless control via a mobile app.

All luminaires are manufactured in our ISO9001:2015 certified facility and carry CE and RoHS markings, confirming their compliance with European safety, health, and environmental protection standards. The high-efficacy design ensures the product also meets the latest ErP (EcoDesign) regulations.

Customisation, MOQ and lead time

As a specialist manufacturer, we excel at tailoring products to meet specific project demands. Beyond standard lengths and finishes, we can produce custom-length luminaires to fit precise architectural dimensions. Custom RAL color finishes are available to match corporate branding or interior design palettes. We can also integrate emergency lighting modules, occupancy sensors, or daylight harvesting sensors directly into the luminaire body for a cleaner installation.

The Minimum Order Quantity (MOQ) for the standard Optix Linear Light series is 50 units. For custom configurations, the MOQ may vary. Our typical production lead time is 20-30 working days from order confirmation to dispatch, depending on the project size and level of customization.

Frequently Asked Questions

Q: What is the warranty period and what does it cover?

A: The Optix Linear Light series comes with a comprehensive 5-year warranty. This covers defects in materials and workmanship, including the LED modules and drivers. We guarantee lumen maintenance of at least L80B10 at 50,000 hours, ensuring long-term performance and reliability for commercial installations. The warranty is valid under specified operating conditions.

Q: How many lumens does the 1500mm version produce?

A: The 1500mm, 48W version of the Optix Linear Light delivers a total system output ranging from approximately 4800 to 6000 lumens. The exact output depends on the selected CCT and CRI; for instance, a 4000K CRI80 version will be more efficient than a 3000K CRI95 version. This equates to a high system efficacy of 100-125 lm/W.

Q: Is this luminaire suitable for a VDU workstation environment?

A: Absolutely. The combination of a wide 140° indirect beam and a controlled 60° direct beam with a low-glare lens allows the system to achieve a Unified Glare Rating (UGR) of less than 19. This makes it fully compliant with the EN 12464-1 standard for lighting workplaces with display screen equipment (DSE), ensuring excellent visual comfort.

Q: Do you provide photometric data for lighting simulation software?

A: Yes, we provide complete photometric files for the entire Optix series. Upon request, we will supply IES and LDT files for all variants, including different lengths, CCTs, and CRIs. These files can be imported directly into professional lighting design software such as DIALux Evo or Relux for accurate 3D modeling and calculation of illuminance levels and light distribution.
