Halo Light
High-efficacy architectural linear systems designed for demanding custom applications
Providing technical security, material compliance, and end-to-end supply chain assurance from Hangzhou
Established as an industry benchmark in linear solid-state lighting, Hangzhou Halo Light Co., Ltd. has evolved into a global force in advanced LED strip light development. Operating out of a key industrial and technical hub in Hangzhou, China, our company integrates sophisticated engineering, automated precision assembly lines, and comprehensive quality validation systems to serve international commercial and architectural markets.
Our modern production facilities are configured for high-volume, zero-defect manufacturing. We specialize in advanced Neon Flex, SMD, and COB/CSP LED lighting solutions, utilizing state-of-the-art surface mount technology (SMT) and continuous reel-to-reel automated processes. This guarantees chromatic consistency, long-term stability, and high luminous efficacy across all product lines.
Rather than simply acting as an assembly provider, we focus on engineering customization. We support clients through detailed thermal modeling, optical simulations, and custom PCB designs to realize projects requiring strict color binning tolerances (SDCM < 3), high color rendering index (CRI 90/95+), and specific international safety certifications (UL, CE, RoHS, CB).
With a strong emphasis on research and development, we have systematically pushed the boundaries of linear form factors. Our progression from standard pitch SMD tape to ultra-dense COB strips containing up to 784 LEDs per meter represents a direct response to architectural demands for dot-free, uniform light emission.
By leveraging double-sided rolled annealed (RA) copper PCBs (up to 3oz thickness), we solve the classic issues of voltage drop and thermal degradation. This ensures that even extended runs remain uniform in both brightness and color temperature over their rated lifespan of 50,000+ hours.
Our quality control labs execute rigorous environmental stress tests on every batch, including thermal shock chamber cycling, UV exposure tests, salt mist spray testing for marine-grade installations, and ingress protection validation up to IP68. This ensures that every shipment meets or exceeds the specifications of international commercial buyers.
Quantified compliance, scale, and performance standards of our manufacturing lines
Tracking the evolution of flexible LED formats from traditional SMD to Next-Gen CSP and Mini LED
Traditional structures utilize 5050, 2835, or 3528 packaging spaced apart. While highly efficient, these arrays require deep diffusion profiles to avoid hot-spots and generate higher local thermal resistance on standard 1oz copper substrates.
Flip-chip packaging directly mounted onto the flexible PCB substrate, covered with a linear phosphor polyurethane or silicone matrix. Eliminates wire bonding, reduces thermal impedance by up to 30%, and offers a seamless light line without visible dots.
CSP technology strips away traditional packaging materials, achieving an area ratio of package size to die size close to 1. This format allows wider viewing angles (up to 160°), superior heat dissipation directly through the solder joint, and ultra-high-density arrays.
Integration of sub-millimeter drive circuits (IC) directly within the flexible matrix. Allows precise local dimming, digital chromatic control, and high-frequency PWM dimming for architectural facades, broadcast studios, and automotive visual systems.
Adapting solid-state linear technology to regional building standards, environmental conditions, and user intent
In North America and Europe, modern office building codes prioritize glare index compliance (UGR < 19) and circadian-supporting Human Centric Lighting (HCL). Our high-density COB and dynamic white strips integrate into DALI/KNX control structures, offering tunable white shifts from 2700K to 6500K to boost occupant focus and comfort.
Outdoor applications in the Middle East and Northern Europe present extreme environmental challenges, from UV exposure to freezing ambient temperatures. Utilizing silicone co-extrusion technology, our IP67/IP68 neon flex strips maintain flexibility and resist yellowing across temperatures ranging from -40°C to +60°C.
Precision healthcare and hospitality projects require dustless, easily sanitized fixtures with zero VOC emissions. Our food-grade silicone-encapsulated linear profiles resist chemicals, sanitizing agents, and moisture, ensuring continuous long-term operation in humid or dust-free environments.

Why sourcing from Hangzhou Halo Light secures your inventory timeline and structural cost advantages
The global linear lighting procurement landscape is heavily dependent on supply chain speed and raw material quality. Operating in Hangzhou, China, places Hangzhou Halo Light Co., Ltd. at the center of the world's most advanced LED components cluster. We source high-grade chips directly from top-tier foundries like San'an and Epistar, bypassing middleman markups to secure priority component allocations.
Our vertical integration covers the entire manufacturing cycle: from automated high-speed SMT placement and silicone extrusion processing to 100% automated spectrophotometric color matching and inline burn-in testing. This deep integration isolates our clients from global component shortages and guarantees consistent lead times even during high seasonal demand.
Additionally, our location provides convenient access to the deepwater ports of Ningbo and Shanghai, as well as Hangzhou International Airport. By utilizing optimized air, sea, and rail freight channels, we provide predictable door-to-door delivery timelines. This is backed by comprehensive export documentation, custom packaging designed for long-distance transport, and complete tariff-compliant customs declarations.
Every batch undergoes 24-hour testing under maximum thermal load. We provide full traceability documentation from silicon chip to finished linear spool.
Answers to key engineering, integration, and manufacturing design questions
Thicker 3oz copper Flexible Printed Circuits (FPCs) significantly reduce electrical resistance, minimizing voltage drop over long linear runs (up to 10-15 meters without double-ended power feed). Crucially, the increased copper mass lowers thermal resistance. This channels heat away from the LED junction to the aluminum mounting profile, preventing chip degradation and maintaining color consistency.
We use high-purity, optical-grade silicone co-extrusion rather than standard PVC. Silicone is chemically inert and highly resistant to both UV degradation and extreme temperatures. It will not yellow, crack, or degrade under direct sunlight. To ensure color consistency, we run all raw LEDs through a strict binning process. This keeps color variations within a 3-step MacAdam Ellipse (SDCM < 3), delivering consistent light across different batches.
Yes. Our core business centers on custom engineering. We develop customized flexible circuit board layouts, custom LED densities, specified color indices (including dual-emitter tunable white, RGBW, and RGBIC), and custom extrusion profiles. We also customize outer dimensions, IP ratings, and wire harnesses to help integrate our lighting directly into your product housing.
Our products carry UL, CE, RoHS, and CB certifications. They comply with critical safety directives and fire safety standards, meeting international requirements for commercial building installations. We perform LM-79 (luminous flux and color metrics) and LM-80 (lumen maintenance) testing on our light engines. This ensures that specifiers, architects, and electrical engineers can easily integrate our systems into certified architectural designs.
Constant Voltage (CV) strips are cost-effective, simple to install, and can be cut at short intervals, but they require careful power distribution to avoid voltage drop over long distances. Constant Current (CC) strips feature integrated ICs that regulate current on every segment. This ensures uniform brightness over long runs and prevents runaway thermal cycles, making them the preferred choice for high-reliability industrial and architectural applications.
