D65 Adjustable Waterproof LED Downlight – Reflector Version

What is the D65 Adjustable Waterproof 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 D65 Watex series Adjustable Waterproof LED Downlight (XH-DL-5W-WT), a compact and versatile luminaire engineered for sophisticated architectural lighting applications. This 5W fixture, designed for a Ø65mm cutout, combines a discreet profile with high-performance optics and robust construction. Its key feature is a 0-30° adjustable tilting mechanism, allowing for precise directional accent lighting. Housed in durable ADC12 die-cast aluminium and rated IP54 on the room-side, it is specifically designed to perform reliably in damp environments such as luxury hotel bathrooms, spas, and covered outdoor soffits, while also excelling in dry applications like retail displays and galleries.

Photometric and electrical specification

The D65 Watex series is designed to meet stringent European and US project requirements. Full IES and LDT photometric files are available for integration into DIALux lighting design software, enabling accurate project simulation.

Which spaces is it designed for?

The D65's combination of adjustability, water resistance, and high-quality light output makes it a preferred choice for specifiers working on hospitality, high-end residential, and boutique retail projects across the EU and US.

How can this fixture be used for accent lighting in hotel bathrooms or spas?

The IP54 rating makes the D65 downlight safe for installation in Bathroom Zone 2 locations per European regulations. Using the 0-30° tilt, designers can precisely aim light to graze a textured stone wall, highlight a vanity area, or illuminate artwork within a spa. The narrow 15° or 24° beam options create dramatic pools of light, adding depth and luxury. Specifying a Dim-to-Warm (e.g., 3000K to 1800K) chip allows guests to transition from a bright, functional light to a warm, candle-like glow, enhancing relaxation.

What makes the D65 suitable for high-end retail displays?

In a retail environment, accurate color and visual comfort are paramount. The D65 excels with available CRI >95 and high TM-30 metrics, ensuring that the colors of fabrics, leather goods, and cosmetics are rendered truthfully. The deep-set reflector helps achieve a UGR<19, preventing distracting glare for customers. The 24° beam is ideal for punching light onto specific products in a display case, while the 38° beam can be used for flexible mannequin highlighting. The adjustable tilt allows for quick reconfiguration as store layouts change.

Can it be specified for corridors and lobbies with sloped ceilings?

Absolutely. The 0-30° adjustability is crucial for architectural spaces with non-standard ceiling planes. It allows contractors to install the housing flush and then aim the light beam vertically downwards, ensuring uniform illumination on the floor path and avoiding unsettling light patterns on walls. For general illumination in these areas, the 60° beam angle provides broad, even coverage. With an efficacy of up to 110 lm/W, the D65 offers an energy-efficient solution for common areas that operate for extended hours.

Installation, control and compliance

Installation is straightforward with a standard Ø65mm cutout and spring clips for a secure fit in plasterboard ceilings from 5mm to 25mm thick. The luminaire connects to a remote driver, offering maximum flexibility in control systems. We support a full range of dimming protocols to integrate with any building management system, including DALI-2 for granular digital control, Casambi (BLE) for intuitive app-based wireless control, and traditional 0-10V or Phase-cut (TRIAC) dimming. The fixture is fully compliant with CE (LVD/EMC), RoHS, and ErP directives, ensuring it meets all safety and energy efficiency standards for the European market.

Customisation, MOQ and lead time

As a manufacturer, we offer extensive customisation. Beyond the standard Matt White and Matt Black finishes, we can produce the D65 in any RAL color to match your project's specific palette. You can specify the exact CCT, CRI, and dimming driver (e.g., Tridonic DALI-2, Osram 0-10V) your project requires. Our Minimum Order Quantity (MOQ) for custom configurations is 100 units. Standard configuration orders have a typical production lead time of 15-25 working days, excluding shipping.

Frequently Asked Questions

Q: What is the IP rating of the D65 downlight and where can it be installed?

A: The D65 Watex has a dual IP rating. The room-facing side is rated IP54, meaning it is protected against dust ingress and water spray from any direction. This makes it suitable for installation in damp locations like bathrooms (EU Zone 2), kitchens, and covered outdoor soffits. The portion of the fixture above the ceiling is rated IP20.

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

A: We provide a 5-year manufacturer's warranty on the D65 series. This warranty covers the failure of the LED module and the electronic driver under normal operating conditions, defined as up to 12 hours of use per day in an environment within the specified temperature range. It ensures peace of mind for long-term installations.

Q: Are there options for very high colour rendering for museum or gallery use?

A: Yes, we specialize in high color fidelity lighting. The D65 can be specified with LED chips offering a Color Rendering Index of CRI95+ or even CRI98+. These options also provide excellent TM-30 metrics and maintain a tight color consistency of SDCM <3, making them ideal for accurately illuminating artwork, artifacts, and high-fashion textiles.

Q: Can I get a sample before placing a large order for my project?

A: Yes, we encourage specifiers and contractors to evaluate our quality firsthand. We can provide 1-2 samples of the D65 downlight for project mock-ups and testing. While our Minimum Order Quantity (MOQ) for a full production run is 100 units, sample orders can be processed quickly to help you finalize your specification with confidence.
