D80 Fixed Waterproof LED Downlight with Reflector

What is the D80 Fixed 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 D80 Watex Series Fixed Waterproof LED Downlight. This luminaire is engineered for architectural spaces where performance, visual comfort, and protection against moisture are paramount. With a compact Ø80mm cutout and a height of just 50mm, it integrates seamlessly into shallow ceiling voids. The housing is constructed from high-grade ADC12 die-cast aluminium for superior thermal management, while the deep-set reflector optic minimizes glare (UGR<19) and delivers precise light control. It is an ideal specification for hotels, high-end residential projects, retail spaces, and wellness centres across Europe, the US, and the Middle East.

Photometric and electrical specification

The D80 Watex Series is built to meet demanding project specifications. We offer full transparency on componentry and performance, ensuring reliability and compliance. Full IES & LDT files are available for DIALux simulation.

Which spaces is it designed for?

The D80 Watex downlight's combination of IP54 rating, high-quality light output, and compact form factor makes it a versatile tool for lighting specifiers and contractors.

How can this downlight be used for hotel bathroom or spa lighting?

For hotel en-suites, guest bathrooms, and spa facilities, the IP54 rating ensures safe operation in damp environments (UK/EU Bathroom Zones 2 and 3). Specifying a warm 2700K or 3000K CCT with a CRI of 90+ creates a relaxing, luxurious atmosphere that renders skin tones accurately. For premium suites, the Dim-to-Warm option (3000K to 1800K) allows guests to transition from functional lighting to a warm, candle-like glow, enhancing the sense of tranquility and comfort.

What makes this suitable for high-end retail accent lighting?

In a high-end retail environment, product presentation is everything. The D80's key advantage is its exceptional color rendering, with options up to CRI98+. This ensures that the colors of textiles, leather goods, and jewelry are displayed vividly and accurately under the light. Using a narrow 15° or 24° beam angle allows designers to create dramatic accent lighting, drawing a customer's eye to specific merchandise and creating a high-contrast, engaging display. The low glare (UGR<19) design ensures a comfortable shopping experience without distracting reflections.

Can it be specified for residential or hospitality corridors with specific ambiance requirements?

Yes, the D80 is an excellent choice for corridors, lobbies, and circulation spaces. Using the wider 38° or 60° beam angles provides smooth, uniform general illumination, ensuring safe passage with light levels of 100-150 lux. By integrating the DALI dimmable driver version with a building management system (BMS), facility managers can schedule lighting levels to dim down during off-peak hours, significantly reducing energy consumption while maintaining a welcoming ambiance. The choice of reflector finish—such as gold for a warmer feel or black for a more dramatic, low-glare effect—allows for further aesthetic tuning.

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

The D80 is designed for straightforward installation with a standard 70-75mm cutout. It connects to an external, constant-current driver, simplifying maintenance. We offer a complete range of control solutions to meet modern smart building requirements. Options include DALI-2 drivers for addressable control, 0-10V/1-10V for simple analogue dimming, and TRIAC (phase-cut) for residential retrofits. For maximum flexibility, we also support wireless control systems like Casambi (BLE) and Zigbee. Full photometric data in IES and LDT photometric files is provided to enable precise planning in lighting design software like DIALux, RELUX, and AGI32. All configurations are certified to CE, RoHS, and ErP standards, ensuring full compliance for projects in the EU and UK.

Customisation, MOQ and lead time

As a specialist manufacturer, we offer extensive customisation. Beyond the standard options, we can provide bespoke solutions for your project. This includes custom RAL color finishes for the luminaire housing, unique CCT/CRI binning, and integration with specific non-standard drivers. A typical Minimum Order Quantity (MOQ) for standard configurations is 50-100 units, while custom fabrications may require an MOQ of 200+ units. Our standard production lead time is approximately 20-25 working days from order confirmation to dispatch.

Frequently Asked Questions

Q: What is the warranty on the D80 downlight?

A: The D80 Watex series comes with a comprehensive 5-year warranty, covering the LED module and the driver. We ensure longevity by using high-quality components from brands like Tridonic and Bridgelux, rated for over 50,000 hours of operation (L80B10). This guarantees performance and reduces maintenance costs for commercial installations.

Q: How do you ensure high color quality?

A: We prioritize color fidelity by offering CRI values up to CRI98+ and specifying all LEDs to be within a 3-step MacAdam ellipse (SDCM<3). This ensures exceptional color rendering and fixture-to-fixture consistency. For projects requiring stringent color evaluation, like museums or high-end retail, we provide TM-30-18 data upon request, with typical Rf values above 90.

Q: Are custom housing or reflector colors available?

A: Yes, customisation is a key part of our service. While our standard finishes are Matt White (RAL9016) and Matt Black (RAL9005), we can accommodate custom RAL color requests for the housing. Reflector finishes include chrome, gold, white, and black. A minimum order quantity (MOQ) of around 200 units may apply for custom finishes.

Q: What level of water protection does this downlight have?

A: The D80 Watex is rated IP54 from the front face when installed correctly into a ceiling. This rating signifies it is protected against dust ingress and splashes of water from any direction. This makes it perfectly suitable for use in bathroom zones 2 and 3, covered outdoor soffits, spas, and other damp environments where direct jets of water are not present.
