Product Description
What is the D110 series Suspended Version LED Downlight and where is it specified?
At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we present the D110 Rube Series Suspended LED Downlight, an architectural pendant fixture engineered for performance and aesthetic flexibility. This luminaire is designed for commercial, hospitality, and high-end residential spaces where direct ceiling mounting is not feasible or desired. Its clean, cylindrical housing (D110mm x H135mm) delivers a powerful and precisely controlled beam from a discreet form factor. With a versatile power range from 20W to 35W and an extensive selection of optical and control options, the D110 suspended downlight is specified by architects and lighting designers in Europe, the US, and the Middle East for projects demanding both high-quality illumination and a modern, minimalist appearance.

Which spaces is it designed for?
The D110 suspended downlight's adaptability makes it a powerful tool for layering light in various professional environments. Its pendant form allows it to bring light closer to the task plane or create visual interest in high-ceiling volumes.
How can I use the D110 suspended downlight to create focal points in a high-ceiling retail space?
For high-ceiling retail environments (3-5 meters), use the D110 in its 35W configuration with a narrow 15° or 24° beam angle. Suspend the fixtures in clusters or linear runs over key merchandise displays, mannequins, or promotional zones. A high-CRI95+ module at 3000K or 4000K will ensure product colors appear vibrant and true, while the focused beam can create dramatic contrast, punching through ambient light to achieve accent factors of 5:1 with illuminance levels exceeding 1500 lux on target.
What is the best configuration for ambient lighting in a hotel lobby or restaurant?
To create a warm and inviting atmosphere in hospitality settings, specify the D110 with wider 38° or 60° beam angles for soft, overlapping pools of light. The Dim-to-Warm option is exceptional here; at full brightness, it provides a functional 3000K, and as it dims for evening service, the color temperature smoothly transitions down to a cozy 1800K candlelight glow. Pairing this with a DALI or Casambi control system allows for automated scene changes throughout the day, ensuring the perfect ambiance for guests with excellent visual comfort (UGR<19).
Can this fixture be used for task lighting over office desks or conference tables?
Absolutely. The suspended format is ideal for delivering functional task lighting directly where needed, independent of the ceiling grid. For office desking or conference tables, suspend the D110 approximately 1.5-2 meters above the work surface. A 25W or 30W version with a 4000K CCT and a 38° beam angle will provide the recommended 500 lux on the task area with minimal glare. The UGR<19 performance is critical in this application to prevent eye strain and maintain productivity.
Installation, control and compliance (DALI-2 / Casambi / 0-10V, CE / RoHS / ErP)
Installation is straightforward via a ceiling-mounted canopy and an adjustable steel suspension cable (standard length 1.5 meters, custom lengths available). The fixture is engineered for compatibility with all major lighting control systems specified in Europe and the US. We offer drivers for wired protocols including DALI-2, Push-Dim, and 0/1-10V for seamless integration into building management systems. For ultimate flexibility and retrofit projects, we provide wireless control options including Casambi (Bluetooth Low Energy), ZigBee, and 2.4G RF. The D110 series is fully compliant with CE (LVD/EMC), RoHS, and ErP directives, ensuring it meets all safety, material, and eco-design standards for commercial projects.
Customisation, MOQ and lead time
As a manufacturer, we offer extensive customisation. Beyond the standard Matt White and Matt Black finishes, the luminaire housing can be powder-coated in any RAL color to match your interior design scheme. The internal reflector is also available in different finishes, including specular silver, gold, white, or black, to further tune the aesthetic and lighting effect. The Minimum Order Quantity (MOQ) for standard configurations is 50 units. For custom RAL colors or other significant modifications, an MOQ of 100 units typically applies. Our standard production lead time is 20-30 working days from order confirmation, depending on component availability and order volume.
Frequently Asked Questions
Q: What is the standard warranty on the D110 series and what does it cover?
A: The D110 series comes with a comprehensive 5-year warranty. This covers the entire luminaire, including the LED module and the driver, against manufacturing defects and premature failure under normal operating conditions. In the event of a failure, we provide replacement components or a complete fixture to ensure your project remains operational and meets the original specification. This warranty is valid for up to 12 hours of use per day.
Q: Can I get this fixture with a custom RAL color finish for my project?
A: Yes, customisation is a key service we offer. For project orders exceeding a minimum quantity of 100 units, we can powder-coat the D110's aluminum housing in any specific RAL color you require. Simply provide us with the RAL code during the specification phase, and we will produce a pre-production sample for your approval before commencing the full order, ensuring a perfect match for your design.
Q: What is the difference between the 'Dim to Warm' and 'Tunable White' options?
A: 'Dim to Warm' mimics the behavior of a traditional incandescent bulb. As you dim the light level down, the color temperature (CCT) automatically becomes warmer, shifting from 3000K at 100% brightness to an intimate 1800K glow at its lowest level. 'Tunable White' provides independent control over brightness and CCT, allowing you to manually set any color temperature between 2700K and 6500K at any intensity.
Q: How do I select the right beam angle for my ceiling height?
A: For accent lighting, use 15° or 24° for ceiling heights up to 4-5 meters to create focused highlights. For general or task illumination from a typical 2.7 to 3.5-meter ceiling, a 38° beam provides a good balance of intensity and coverage. The 60° beam angle is best for lower ceilings or when you need wide, soft ambient light from a greater suspension height.
