Round Waterproof D100 LED Downlight 10-15W Custom Design

What is the Round Waterproof D100 LED Downlight and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we engineer luminaires for precise commercial applications, and the Round Waterproof D100 LED Downlight is a prime example of this philosophy. This fixture is a high-performance, specification-grade downlight designed for environments where moisture resistance and lighting quality cannot be compromised. As part of a broader series, the D100 model (Ø100mm, 10W) and its D135 counterpart (Ø135mm, 15W) are distinguished by their front-face IP65 rating, making them fully protected against dust ingress and jets of water. This allows specifiers in the EU, US, and Middle East to confidently deploy high-quality, glare-controlled lighting in bathrooms, spas, kitchens, and exterior soffits without risking premature failure. Constructed from ADC12 die-cast aluminium with superior thermal management, it offers a robust and reliable solution for demanding architectural projects.

Photometric and electrical specification

The D100/D135 series is built to order, allowing specifiers to select the exact performance characteristics required for their project. Full IES and LDT photometric files are available for all configurations to enable accurate lighting simulations in software such as DIALux.

Which spaces is it designed for?

The versatility of the D100/D135 series allows it to be specified across a wide range of commercial and high-end residential environments where performance and durability are paramount.

How does IP65 protection extend its use in hospitality and residential projects?

The IP65 rating is the key feature that sets this downlight apart for hospitality and residential applications. It is fully sealed against water projected from a nozzle, making it safe and durable for installation within Bathroom Zone 1 in the EU and UK (above a bath or shower). This allows for consistent, high-quality lighting design to flow from dry areas into wet rooms, spas, luxury ensuites, and high-humidity kitchens. The robust ADC12 die-cast aluminium housing with a durable powder-coat finish also makes it suitable for exterior soffits and covered walkways, resisting corrosion and ensuring a long service life of over 50,000 hours.

What makes this downlight suitable for high-end retail or museum displays?

For retail and gallery spaces, color accuracy and visual impact are critical. This fixture excels with its optional museum-grade colour rendering, achieving a Color Rendering Index up to CRI98+ and TM-30-18 metrics of Rf>90. This ensures that the colors of fabrics, artwork, and merchandise are rendered vibrantly and accurately. Combined with narrow beam angles of 15° or 24°, specifiers can create dramatic accent lighting, drawing attention to key displays with high punch and sharp contrast. The low-glare design (UGR<19) further enhances the viewing experience, preventing distracting reflections and allowing customers or visitors to focus on the illuminated objects.

Can this fixture be used for general office and circulation area lighting?

Yes, when configured with wider beam angles of 38° or 60° and a CCT of 4000K, the D100/D135 series serves as an excellent general illumination tool. Its high efficacy (up to 130 lm/W) helps achieve target lux levels of 300-500 lux for office environments while minimizing energy consumption. The availability of UGR<19 versions is crucial for compliance with the European standard for workplace lighting, EN 12464-1, ensuring visual comfort for employees and reducing eye strain at workstations and in meeting rooms. The flicker-free output from premium drivers further contributes to a productive and comfortable environment.

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

Installation is streamlined for professional contractors. The 10W D100 model requires a standard Ø90mm cutout, while the 15W D135 model uses a Ø125mm cutout. The fixture is secured with spring clips, and the external driver allows for a slim profile in the ceiling void and better thermal management. We offer extensive control protocol support to integrate into any building management system. Options include DALI-2 for granular digital control, 0-10V analog dimming, and phase-cut (TRIAC) dimming for residential retrofits. For wireless flexibility, we also offer Casambi (Bluetooth Low Energy) and Zigbee control modules. Full compliance with CE, RoHS, and ErP directives ensures the product meets all safety, environmental, and performance standards for the European market.

Customisation, MOQ and lead time

As a manufacturer, we specialize in tailoring products to project-specific needs. Beyond the standard options, we offer customisation for luminaire finishes to any RAL color to match interior design palettes. We can pre-configure fixtures with specific LED chips and drivers from brands like Tridonic or Mean Well to meet client preferences. Minimum Order Quantity (MOQ) for standard configurations is 100 units. For custom RAL finishes or non-standard CCTs, the MOQ may be higher. Our typical production lead time is 20-25 working days from order confirmation to dispatch from our factory in China.

Frequently Asked Questions

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

A: An IP65 rating indicates the luminaire is completely dust-tight (the '6') and protected against low-pressure water jets from any direction (the '5'). This allows you to safely install the D100 downlight in moisture-prone areas like bathrooms (including EU Zone 1 over a shower), kitchens, laundry rooms, and covered outdoor spaces like soffits or verandas. The protection is applied to the front face that is exposed to the room.

Q: Can I get a specific color temperature not listed as standard?

A: Yes, customisation is one of our core services. While we stock common CCTs like 3000K and 4000K, we can manufacture batches with a specific CCT between 2700K and 6500K to meet your project's exact requirements. All our LEDs are binned to within a 3-step MacAdam ellipse (SDCM<3) for excellent color consistency. A minimum order of 200 units may apply for such custom requests.

Q: Are photometric files available for lighting simulation?

A: Absolutely. We provide comprehensive photometric data for lighting designers and engineers. You can request IES and LDT files for any configuration of the D100 series. These files are essential for accurate lighting calculations and visualizations in professional software like DIALux or RELUX, ensuring your design meets the specified lux levels, uniformity, and glare ratings before installation.

Q: What is the warranty and which driver brands do you use?

A: The Round Waterproof D100 LED Downlight is backed by a comprehensive 5-year manufacturer's warranty covering the entire luminaire, including the LED module and driver. To ensure maximum reliability and compatibility, we exclusively use globally recognized, specification-grade driver brands such as Tridonic, Osram, Philips, and Mean Well. This guarantees stable performance and seamless integration with control systems like DALI-2 and 0-10V.
