Aurora Cascade — Custom K9 Crystal Chandelier for Hotel Lobby

What is the Aurora Cascade and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we engineer architectural statements that define luxury spaces. The Aurora Cascade is the pinnacle of our bespoke chandelier collection, a multi-tier waterfall of light and crystal designed specifically for the grand scale of five-star hotel lobbies, ducal ballrooms, and luxury retail atriums. It is not an off-the-shelf product but a collaborative creation, specified by architects and interior designers who require a unique, site-specific centrepiece. Each K9 high-purity teardrop crystal is hand-cut, polished, and precisely set into a custom-fabricated frame, creating an immersive cascade of refracted light. This fixture is engineered to create an unforgettable first impression, delivering both ambient illumination and unparalleled decorative impact. The design process is fully supported by our technical team, providing everything from initial concept sketches to detailed structural drawings and photometric files for simulation.

Photometric and electrical specification

The Aurora Cascade is a fully customised luminaire. The following specifications are typical for a reference design of Ø1800mm x H3500mm, but all parameters can be adjusted to meet project requirements in the European, American, or Middle Eastern markets.

Parameter	Specification	Standard	Notes
Optics
Color Temperature (CCT)	2200K / 2700K / 3000K; Tunable White optional	ANSI C78.377	Warm, inviting tones for hospitality. Tunable options (e.g., 2200-3000K) allow for mood setting.

Which spaces is it designed for?

The Aurora Cascade is conceived for double-height and multi-story spaces where a powerful design statement is essential. Its primary application is within the luxury hospitality sector, but its adaptable design language makes it suitable for a range of high-end commercial and public environments.

How does the Aurora Cascade enhance the guest arrival experience in a hotel lobby?

In a hotel lobby, the goal is to create an immediate sense of wonder and luxury—a 'sense of arrival'. The Aurora Cascade achieves this by acting as the primary visual anchor. During the day, its thousands of crystal facets capture and refract natural light. At night, its warm, dimmable LEDs (typically 2700K with CRI>95) create an intimate and welcoming glow. The sheer scale and cascading form draw the eye upwards, emphasizing the grandeur of the space and setting a sophisticated tone for the entire guest experience. Dimmable control via DALI or DMX allows the lighting level to transition seamlessly from a bright, energetic welcome to a subdued, relaxing evening atmosphere.

Can this chandelier be scaled for a multi-story atrium or ballroom?

Absolutely. The modular engineering of the Aurora Cascade allows for complete customisation of its dimensions. For a multi-story atrium, the height can be extended to 10 meters or more, creating a visually stunning link between floors. The diameter can be scaled from a standard 1.8 meters up to 5 meters or larger for expansive ballrooms. Our process involves creating detailed 3D models and renderings to help you visualise the chandelier's scale within your space. We also provide comprehensive structural analysis and mounting specifications to ensure a safe and secure installation, regardless of the final size and weight.

What design considerations are there for integrating with existing architecture?

Integration is key. Our design process begins with your architectural plans and interior design concepts. We consider sightlines from all key areas—the entrance, reception desk, mezzanine levels—to ensure the chandelier is impactful from every angle. The frame finish can be custom-matched to existing metalwork, window frames, or hardware using RAL codes. We also conduct photometric analysis using DIALux evo to ensure the chandelier provides the desired ambient lux levels (e.g., 150-200 lux in a lobby) without creating unwanted reflections on glass or polished surfaces. We provide full IES and LDT photometric files for your lighting designer to incorporate into their overall lighting scheme.

Installation, control and compliance

Every Aurora Cascade is a significant structural element, and we treat it as such. We provide detailed installation drawings, including total weight, anchor point loads, and assembly instructions. We strongly recommend using certified structural engineers and professional installers. On-site installation guidance from our engineering team is available as part of our service package for complex projects.

Control is specified per project. We support all major commercial lighting control protocols:

• DALI-2: For granular digital addressability, diagnostics, and seamless integration into building management systems (BMS). Ideal for modern European specifications.
• 0-10V: A robust and widely used analog dimming standard, common in US commercial projects.
• DMX: For dynamic, scene-setting capabilities often required in ballrooms and event spaces.
• Wireless Control: Integration with systems like Casambi is possible via DALI or 0-10V gateways, offering app-based control and scene recall.

Compliance is guaranteed. All components are CE marked and RoHS compliant for the EU market. For projects in North America, we manage the process of obtaining UL or cUL listing, ensuring the final fixture meets all local safety and electrical codes.

Customisation, MOQ and lead time

As a bespoke fixture, every Aurora Cascade is unique. The customisation process is comprehensive and client-focused.

• Minimum Order Quantity (MOQ): 1 set. We are a project-based manufacturer and specialise in one-of-a-kind installations.
• Lead Time: Typically 45 to 90 days, depending on design complexity, scale, and material approvals. The process timeline is as follows:
  1. Concept & Quotation (3-5 days): Based on your drawings and requirements.
  2. Shop Drawings & 3D Renders (7-10 days): For your approval.
  3. Material Samples & Mock-ups (10-15 days): If required for sign-off.
  4. Fabrication & Assembly (25-50 days): Hand-cutting crystal, fabricating the frame, and wiring.
  5. Quality Control & Shipping: Rigorous testing before crating and shipping.

Our service extends to providing concept sketches, 3D renderings, material samples, and full structural documentation to ensure the final product perfectly matches your vision.

Frequently Asked Questions

Q: What is the quality and origin of the K9 crystal you use?

A: We use premium-grade K9 crystal, an optical borosilicate crown glass known for its exceptional clarity, high refractive index (1.516), and durability. It contains no lead, making it an environmentally friendlier choice than traditional lead crystal. K9 offers over 90% of the sparkle and brilliance of full-lead crystal, ensuring a dazzling effect without the associated weight and cost, making it ideal for large-scale architectural installations.

Q: How much structural support is required for a large chandelier?

A: Structural support is critical and project-specific. A typical Aurora Cascade measuring Ø1.8m x H3.5m can weigh between 250 kg and 400 kg. We provide precise weight calculations and anchor point load diagrams for your project's structural engineer. They must verify the ceiling's load-bearing capacity and specify the necessary reinforcement, such as a dedicated steel sub-frame above the finished ceiling.

Q: What is the maintenance and expected lifespan of the fixture?

A: The K9 crystal elements require periodic dusting or professional cleaning. The LED light sources, typically G9 or E14 bulbs, have a rated L70 lifespan of 50,000 hours. In a commercial lobby operating 12 hours a day, this translates to over 11 years of service before the light output drops to 70%. We provide a 5-year manufacturer's warranty covering the entire fixture, including drivers and LEDs.

Q: What is the payment and design process for a custom order?

A: The process begins once we receive your inquiry and design brief. After initial consultation, we provide a quotation. To proceed with detailed shop drawings and 3D renderings, a design deposit may be required. Full production commences upon your approval of the drawings and receipt of a 50% deposit. The final 50% balance is due before the fixture is shipped from our factory. The entire process takes between 45 and 90 days.
