D65 Adjustable Waterproof LED Downlight – Lens Version

What is the D65 Adjustable Waterproof LED Downlight – Lens Version and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we present the D65 Watex series adjustable waterproof LED downlight, an essential tool for lighting specifiers focused on hospitality, high-end residential, and retail projects. This 5W luminaire combines a compact form factor (Ø65mm x 50mm height) with powerful functionality. Its key feature is a 0-30° adjustable tilt mechanism, allowing for precise accent and wall-wash lighting from a discreet aperture. The precision lens optics ensure clean, controlled beams without flare, making it superior to standard reflector-based downlights for creating focused impact. Engineered for durability and safety in damp locations with an IP44/IP54 rating, the D65 is a versatile solution for EU, US, and Middle Eastern markets requiring high-performance, specification-grade lighting.

Photometric and electrical specification

The D65 is designed for full customisation to meet stringent project requirements. We provide complete photometric data, including IES and LDT files, for integration into DIALux and other lighting design software.

Which spaces is it designed for?

The D65's combination of adjustability, water resistance, and high-quality optical control makes it a prime candidate for spaces where both ambiance and task precision are required. It excels in applications from luxury hotel bathrooms and spa wellness centers to niche retail displays and modern office breakout zones.

How can this downlight be used for accent lighting in a hotel guest room or bathroom?

In a hotel environment, the D65 offers targeted flexibility. Use the 30° tilt to direct a narrow 24° beam onto a piece of artwork or to graze a textured wall behind the bedhead, adding depth and drama. In the bathroom, its IP54 rating makes it perfectly safe for installation over vanities or in shower niches (outside direct water jets). A high CRI >95 specification ensures guest skin tones are rendered naturally at the mirror. Specifying the Dim-to-Warm option allows the lighting to transition from a bright, functional 3000K to a warm, relaxing 1800K glow for evening use.

What makes the D65 suitable for high-end retail display cases or niches?

For luxury retail, lighting must be impactful yet invisible. The D65's small 65mm trim and deep-set lens create a 'quiet ceiling,' drawing attention to the merchandise, not the light source. The availability of CRI >98 and high R9 values (>90) is critical for accurately rendering the color of jewelry, leather goods, and fine fabrics. The adjustable tilt allows for precise aiming within display cases or onto mannequins, while the low-power 5W LED produces minimal heat, protecting delicate products. A 15° beam can create a dramatic highlight on a single watch, while a 38° beam can wash a collection of handbags.

Can the D65 downlight contribute to a UGR<19 lighting scheme in an office breakout area?

While general office lighting often relies on large-format troffers to achieve a low Unified Glare Rating (UGR), accent lights like the D65 play a crucial supporting role. By using the D65 to wall-wash with its 60° beam or highlight architectural features, you can increase vertical illuminance and create a more balanced, comfortable environment, which helps lower the overall perceived glare. The deep-set position of the lens inherently reduces high-angle glare. For a definitive result, our technical team recommends using our IES and LDT photometric files to run a full simulation in DIALux to verify the UGR<19 compliance for the entire space layout.

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

Installation of the D65 is straightforward, requiring a standard ceiling cutout of approximately 55-58mm. The luminaire is secured with spring clips. The fitting's 50mm height is ideal for shallow ceiling voids, though adequate space must be left for the separate remote driver (dimensions vary by brand and protocol). We strongly recommend a minimum clear void depth of 90mm for proper ventilation.

Control is a core part of our customisation. We offer drivers compatible with all major protocols:

• Wired: DALI-2, 0-10V/1-10V, and TRIAC (leading/trailing edge) phase dimming.
• Wireless: Casambi (Bluetooth Low Energy), ZigBee, and other 2.4G RF systems.

All configurations are CE marked, compliant with the Low Voltage Directive (LVD), Electromagnetic Compatibility (EMC) Directive, Restriction of Hazardous Substances (RoHS), and the Energy-related Products (ErP) Directive.

Customisation, MOQ and lead time

As a manufacturer, we tailor the D65 to your exact project needs. Beyond the standard options, we offer custom RAL colour finishes for the housing to match any interior design scheme. You can specify the exact CCT, CRI, and driver brand that your project demands.

• Minimum Order Quantity (MOQ): MOQs begin at 100 units for standard configurations. For custom RAL finishes or highly specific LED chips, the MOQ may be higher. Please consult with our sales team.
• Lead Time: Our standard production lead time is 15-20 working days from order confirmation. Custom orders requiring unique components may extend to 30 working days.

Frequently Asked Questions

Q: What is the required ceiling cutout and void depth for installation?

A: The D65 requires a ceiling cutout of approximately 55mm. The fitting itself has a height of only 50mm, but you must account for the remote driver and adequate ventilation. We recommend a minimum clear void depth of 90mm to accommodate the driver and ensure proper thermal management, which is crucial for the 5-year warranty.

Q: Is the IP44/IP54 rating maintained when the downlight is tilted?

A: Yes, the IP rating is maintained across the full 0-30° tilt range. The fixture's front face is sealed with a protective gasket and a sealed lens assembly. This ensures protection against water splashes from any direction, making it fully compliant for installation in bathroom Zone 2 and other damp locations, even when angled to highlight a feature.

Q: Can I get this fixture with a specific CRI like CRI98 and R9>90?

A: Absolutely. We specialize in high-fidelity lighting. We can supply the D65 with CRI98+ LEDs, which typically achieve an R9 value exceeding 90. This specification is ideal for museum-quality lighting or high-end retail where accurate colour rendition, especially for reds, is critical. Please specify this requirement when requesting a quotation for accurate LDT files.

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

A: The D65 Adjustable Waterproof LED Downlight comes with a comprehensive 5-year warranty. This covers defects in materials and workmanship, including LED lumen depreciation below L80B10 and driver failure. The warranty is contingent on proper installation according to our guidelines, including adequate ventilation, and operation within the specified ambient temperature range of -20°C to +45°C.
