Which spaces is it designed for?

As a versatile accent and general lighting tool, the D115 series is ideal for US and European specifiers working on a range of commercial projects where light quality and control are paramount.

How can I use the D115 to create dramatic accent lighting in a luxury retail boutique?

For high-end retail, the D115 excels at creating focal points that draw customers to merchandise. Use the narrow 15° or 24° beam angles to 'punch' light onto mannequins, handbags, or jewellery displays, achieving illuminance levels of 1500-2000 lux. Specify a high-fidelity CRI95+ or CRI98+ chip at 3000K to render textiles, leathers, and skin tones with absolute accuracy. The 355° rotation and 30° tilt allow for precise aiming, while the fixture's low glare (UGR<19) design ensures a comfortable, premium shopping experience without distracting reflections.

What makes this fixture suitable for hotel lobby and corridor lighting plans?

The D115's adaptability is perfect for the varied demands of hospitality lighting. In a hotel lobby, use multiple 24° fixtures to create pools of light over seating areas or to highlight architectural features. For corridors, a wider 36° or 60° beam provides comfortable general illumination. Specifying the Dim-to-Warm (DTW) option allows the ambiance to shift from a bright, welcoming 3000K during the day to an intimate, warm 1800K in the evening. Integration with DALI or Casambi control systems enables automated scene changes, while the robust 5-year warranty and 50,000-hour L80 lifetime minimize maintenance for 24/7 operations.

Can this downlight meet the visual comfort requirements for modern office spaces?

Absolutely. While not a primary source for broad ambient lighting, the D115 is a superb tool for accent and ancillary lighting in contemporary office designs. It easily meets the EN 12464-1 requirement for UGR<19, making it suitable for breakout zones, reception areas, and boardrooms. Use it to wash a wall with a logo, highlight artwork, or provide focused light in collaboration pods. A neutral 4000K CCT promotes alertness. Paired with our premium flicker-free drivers from Tridonic or Osram, it helps create a productive and visually comfortable environment, free from fatiguing strobing effects.

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

Engineered for efficient installation by electrical contractors, the D115 requires a standard square 95x95mm ceiling cutout and is secured by durable spring clips. The luminaire is powered by an external driver, which improves thermal management and simplifies maintenance. We offer a full suite of control solutions to match any project scale. DALI-2 drivers provide individual addressability and feedback for smart building integration. 0-10V and phase-cut (TRIAC) dimming offer simple, reliable control. For retrofits or projects requiring wireless flexibility, we offer drivers compatible with Casambi (Bluetooth) and Zigbee mesh networks.

All products are fully certified with CE (LVD, EMC), RoHS, and ErP, ensuring compliance for import and installation across the European Union and other regulated markets.

Customisation, MOQ and lead time

As a manufacturer, we specialize in tailoring products to your exact project needs.

Standard production lead time is approximately 15-20 working days from order confirmation. For large-volume or highly customized orders, the lead time is typically 25-30 working days. We work closely with your project timeline to ensure timely delivery to your site or logistics partner.

Frequently Asked Questions

Q: What are the high color rendering options available for this downlight?

A: We offer exceptional color rendering with CRI90+, CRI95+, and even CRI98+ options. For applications like art galleries or high-end fashion, our CRI98+ version with an R9 value greater than 95 ensures colors appear vibrant and true. All our high-CRI LEDs maintain a tight color consistency of less than 3 SDCM across the entire 50,000-hour rated lifetime.

Q: Is the D115 downlight compatible with common building management systems?

A: Yes, it is highly compatible. We primarily specify DALI-2 drivers from Tridonic or Osram for seamless integration into addressable building management systems. We also offer 0-10V, and wireless Casambi (Bluetooth Low Energy) options for flexible control. Our engineers can support specifications to ensure full compatibility with your project's control infrastructure, covering over 7 major protocols.

Q: What is the operational lifetime and warranty for the D115 Series?

A: The D115 series is backed by a comprehensive 5-year manufacturer's warranty. The luminaire is engineered for longevity, with a rated lifetime of L80B10 > 50,000 hours. This means that after 50,000 hours of operation, at least 90% of the fittings will still provide over 80% of their initial light output, ensuring a durable and low-maintenance installation.

Q: How much can the spotlight be adjusted after installation?

A: The D115 provides significant aiming flexibility. It features a 355° rotational axis and a 30° vertical tilt. This gimbal mechanism allows for precise focusing of light onto vertical surfaces, artwork, or retail displays, even after the fixture is securely installed in the 95x95mm ceiling cutout. This makes it ideal for dynamic spaces where displays frequently change.
