Why Tonghua Lighting
B2B Lighting Solutions Engineered for Performance
Tonghua Lighting is a professional LED lighting manufacturer based in Haining, China, serving global B2B clients with lighting systems designed to IES standards. Our engineering team handles everything from initial lux calculations and photometric analysis to fixture selection, installation guides, and post-installation support. We specialize in commercial lighting for hotels, retail stores, offices, restaurants, warehouses, and outdoor applications, providing custom solutions that balance energy efficiency, visual comfort, and brand-appropriate aesthetics.
Photometric Design & Simulation
Our lighting engineers use Dialux and AGi32 photometric software to simulate lux distributions, uniformity ratios (min/avg), and glare indices (UGR) before any fixture is manufactured. This ensures every project meets IES recommended illumination levels for its specific application, whether it is a 500-lux retail showroom or a 200-lux warehouse aisle.
CRI 90+ Color Accuracy
For retail, hospitality, and art gallery applications, color rendering index (CRI) directly impacts how merchandise and spaces appear. Our LED fixtures achieve CRI 90+ and R9 50+ values, ensuring red tones render accurately and products look their best under our lighting.
IP65+ Outdoor Durability
Outdoor lighting fixtures are built with IP65 to IP66 ingress protection ratings, using 316L stainless steel hardware and marine-grade aluminum housings for coastal and harsh-environment installations. All outdoor fixtures carry UL and CE certifications.
Dimming & Smart Controls
We integrate 0-10V, DALI, and triac dimming systems into our lighting designs, allowing B2B clients to adjust illumination levels for different times of day, occupancy patterns, or ambient light conditions. Smart control options include motion sensors, daylight harvesting, and scheduling via Building Management Systems (BMS).
Energy Efficiency & ROI
Our LED retrofits typically achieve 50-70% energy savings compared to halogen and fluorescent systems, with payback periods of 12-24 months. We provide detailed ROI calculations including energy savings, maintenance cost reduction, and potential utility rebate eligibility for each project.
Global Certification & Warranty
All fixtures carry UL, ETL, CE, RoHS, and FCC certifications for international compliance. We offer 5-year warranties on LED drivers and chips, with L70 lifespans exceeding 50,000 hours. Project documentation includes photometric reports, IES files, and installation drawings.
