FAQ
1. PCB Construction & Quality
Xuanan Lighting utilizes 2-oz copper PCBs as standard, with 3-oz and 4-oz options available for enhanced thermal management. All boards feature 100% pure copper layers and are sourced from UL-certified manufacturers, including Hongqi Lighting and Founder Soonest Electronics, ensuring consistent reliability and performance.
2. LED Chip Selection
We standardize on Epistar LEDs for balanced performance and durability, while offering alternative chips—including Cree, Samsung, Philips, San’an, Honglitronic, and Smalite—to meet specific spectral, efficacy, or cost requirements. All chips are selected from premium bins to ensure long-term stability and output.
3. Color Rendering & Consistency
Our LED strips begin at a minimum of Ra80 CRI, with typical batch measurements averaging Ra83 under integrating sphere testing. We regularly supply Ra90 and Ra95 solutions for architectural, retail, and museum-grade applications. Full spectral test reports are available for every production batch.
4. Chromatic Uniformity
We strictly control color temperature binning across all LED strips, ensuring visual consistency in both single installations and repeat orders. This eliminates patchiness or tonal shifts, even across large-scale or multi-phase projects.
5. IP Protection & Encapsulation
In addition to conventional IP65, IP67, and IP68 rated sleeves, we offer dotless silicone extrusion for seamless IP65–IP68 protection in milky or transparent coatings. Most of our extrusion tools are custom-designed, enabling unique profiles and superior weather resistance.
6. Custom Engineering Support
Our engineering team supports full OEM/ODM development—from flexible and rigid PCB layouts to pixel module design—delivering swift prototype readiness and production-file approval. We welcome global collaborations with custom specification requirements.
