Round Waterproof D85 LED Downlight 5-10W Supplier

What is the Round Waterproof D85 LED Downlight and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we present our versatile Round Waterproof LED Downlight series, beginning with the compact 5W D85 model. This architectural luminaire is engineered for environments where moisture, dust, and aesthetic precision are primary concerns. Built from robust ADC12 die-cast aluminium and sealed to an IP65 rating, it is a reliable solution for challenging indoor and wet-location applications across Europe, the US, and the Middle East. With a minimal Ø75mm cut-out for the 5W version, it provides a clean, trimless-style appearance while delivering high-performance lighting. This series, which extends up to 30W, is designed for lighting specifiers, contractors, and architects who require certified, durable, and visually superior lighting for commercial, hospitality, and high-end residential projects.

Photometric and electrical specification

This series is engineered for flexibility and compliance with stringent international standards. We provide complete IES and LDT photometric files for all configurations to facilitate accurate lighting design in software like DIALux.

Which spaces is it designed for?

This IP65 downlight is a high-performance tool for designers specifying for a range of demanding environments. Its combination of robust construction and high-quality optical control makes it suitable for spaces where standard downlights would fail or underperform.

How can this IP65 downlight be used in high-end hospitality projects?

In luxury hotels and wellness centers, the D85 and D100 models excel in guest bathrooms, shower enclosures, spas, and fitness center changing rooms. The IP65 rating ensures safety and longevity in these high-humidity zones. Specifying a warm CCT of 2700K or 3000K with a high CRI of >95 creates a welcoming and relaxing ambiance, rendering skin tones and materials beautifully. With DALI-2 or Casambi wireless controls, you can program lighting scenes—from bright functional light for the morning to a soft, dimmed glow for evening relaxation—enhancing the guest experience and adding a layer of sophisticated automation.

What are the benefits for retail and commercial specifications?

Beyond wet areas, this downlight is ideal for commercial spaces that require durable, low-maintenance lighting. Applications include covered exterior walkways, building soffits, entrance canopies, and restrooms in office buildings and shopping centers. The robust ADC12 aluminium body and 5-year warranty ensure a low total cost of ownership. For task-oriented commercial spaces or corridors, the 4000K CCT option combined with a 38° or 60° beam angle provides excellent general illumination, while careful planning can achieve UGR<19 to meet workplace lighting standards like EN 12464-1, ensuring visual comfort for employees and visitors.

Is this fixture suitable for premium residential or multi-family buildings?

Absolutely. For premium homes and apartment complexes, the D85 downlight offers a discreet and powerful lighting solution for kitchens, bathrooms, and covered balconies. Its small Ø85mm trim and Ø75mm aperture blend seamlessly into modern ceilings for a minimalist aesthetic. The availability of common TRIAC dimmable drivers ensures compatibility with standard residential dimming systems, making it an easy upgrade. The Dim-to-Warm (DTW) option, which shifts from 3000K to 1800K as it dims, is particularly popular for creating the cozy, incandescent-like atmosphere desired in living spaces and bedrooms.

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

Installation is streamlined with a standard round cut-out (Ø75mm for the 5W D85, Ø90mm for the 10W D100) and spring-loaded clips for a secure fit in plasterboard ceilings. The luminaire connects to an external driver, which can be specified with a wide range of control protocols to integrate into any building management system. We offer:

• DALI-2: For addressable digital control in commercial buildings.
• 0-10V/1-10V: A simple and reliable analog dimming standard.
• TRIAC (Phase-cut): For cost-effective dimming in residential applications.
• Wireless: Bluetooth Mesh (Casambi) and Zigbee options for retrofits and flexible control without new wiring.

Full compliance with European directives is guaranteed. The series is CE marked, confirming adherence to LVD and EMC standards, RoHS compliant for hazardous substances, and designed to meet current ErP eco-design requirements. Our manufacturing processes are certified to ISO9001 quality management standards.

Customisation, MOQ and lead time

As a manufacturer, we specialize in tailoring products to specific project needs. Customisations for this series include non-standard RAL color finishes to match any interior design palette, specific CCT and CRI binning from our premium LED suppliers, and sourcing of project-specified drivers. The minimum order quantity (MOQ) for standard configurations is 100 units. For custom orders, the MOQ may vary. Standard production lead time is typically 20-25 working days after drawing confirmation, with global shipping options available to the EU, US, and Middle East.

Frequently Asked Questions

Q: What does the IP65 rating practically mean for installation locations?

A: An IP65 rating signifies that the luminaire is completely dust-tight (the '6') and protected against low-pressure water jets from any direction (the '5'). This makes it safe and durable for installation directly within a shower enclosure (Zone 1 in the UK), in bathrooms, spas, kitchens, and in covered outdoor areas like soffits and porticos. This protection is covered by our 5-year warranty, ensuring long-term performance in these demanding environments.

Q: What is the main difference a specifier should consider between CRI90 and CRI98?

A: While a CRI of >90 provides excellent color rendering for most commercial and hospitality applications, CRI >98 is specified for spaces where color fidelity is critical. This includes high-end retail displaying luxury goods, art galleries, and museum exhibits. A CRI98 luminaire, which often has a TM-30 Rf value over 95, reproduces colors with almost perfect accuracy, ensuring that fabrics, artwork, and finishes appear exactly as intended by the designer.

Q: What is the estimated lead time for an order of 500 units to be delivered to the USA?

A: For a project order of 500 units, our standard production lead time is approximately 25-30 working days after all technical specifications and drawings are finalized and approved. Air freight to the United States typically takes an additional 7-10 days, while sea freight can take 30-40 days. We work closely with your project timeline to coordinate production and delivery for a smooth installation schedule.

Q: Is this downlight compatible with smart home systems like Casambi?

A: Yes, it is fully compatible. We can supply the D85 series with a Bluetooth Low Energy (BLE) driver that integrates seamlessly into a Casambi wireless control network. This allows for advanced control via a smartphone app, including dimming, CCT tuning (for TW versions), scene-setting, and scheduling without the need for new control wiring. It's an ideal solution for both retrofit projects and new builds seeking flexible, user-friendly smart lighting.
