K9 crystal is a high-grade optical glass containing 9% lead oxide, which gives it superior clarity, brilliance, and light refraction compared to regular glass. It's the most popular crystal type for chandeliers because it offers 95% of the sparkle of luxury Austrian crystal (like Swarovski) at a fraction of the cost. K9 crystal is durable, scratch-resistant, and produces beautiful rainbow prisms when light passes through. At Diansheng Lighting, all our crystal chandeliers use premium K9 crystal sourced from top Chinese manufacturers.

The general rule: Add your room's length and width in feet, and the sum equals the chandelier diameter in inches. For example, a 20ft x 16ft room = 36-inch chandelier. For dining tables, choose a chandelier 1/2 to 2/3 the table width. For hotel lobbies, use 1/5 to 1/3 of the ceiling height as the chandelier height. Hang 30-36 inches above a dining table or 7+ feet above the floor in open areas. For commercial projects, we recommend contacting our design team for a free size consultation based on your specific space dimensions.

Yes, Chinese crystal chandeliers can be excellent quality when sourced from reputable manufacturers. At Diansheng Lighting, we use premium K9 crystal with 9% lead content for superior clarity and brilliance. All our products are CE, UL, and RoHS certified, matching international quality standards. We implement 3-stage quality inspection (raw materials, in-production, pre-shipment) and have served 500+ projects in 50+ countries since 2016. The key difference between a good and poor Chinese chandelier is the manufacturer's quality control process — always verify certifications and visit the factory when possible.

Clean your crystal chandelier every 6-12 months for best results. Method 1: Spray cleaning — mix 1 part isopropyl alcohol with 3 parts distilled water in a spray bottle. Lay a cloth below, spray the crystal prisms, and let them drip-dry for a streak-free finish. Method 2: Glove cleaning — wear cotton gloves, lightly spray with the solution, and wipe each crystal gently. Never use ammonia-based cleaners or rotate the chandelier while cleaning. For large hotel chandeliers, we recommend professional cleaning services. Our chandeliers come with detachable crystal components that make maintenance easier.
