Introduction
In the realm of professional LED lighting, long-distance uniform illumination has long been a pain point-traditional LED COB strips suffer from noticeable brightness dips beyond 5-10 meters, requiring complex power injectors or parallel wiring that increases costs and installation time. For architects, contractors, and project managers working on large-scale spaces like commercial buildings, cultural tourism landscapes, and industrial facilities, this limitation compromises both aesthetics and functionality.
Our 30m long DC48V COB480 COB LED strip redefines long-run lighting standards, leveraging DC48V constant current technology to deliver 30 meters of seamless, zero-voltage-drop illumination. As a professional LED COB Strip manufacturer with 12+ years of expertise, we've engineered this product to combine ultra-long run capability with 480chip/m density, CRI>90 color accuracy, and multiple IP ratings (IP20/65/68) to meet diverse project needs. Backed by CE/ROHS certifications and rigorous quality control, it's not just a lighting COB strip-it's a cost-effective, hassle-free solution for large-scale lighting projects that demand consistency, durability, and professional performance.

Advantages
The biggest breakthrough of this product lies in its ability to maintain consistent brightness across 30 meters-eliminating the voltage drop that plagues 12V/24V COB strips. This is made possible by DC48V constant current design, which reduces current flow while maintaining power output, minimizing energy loss over long distances.
Project Case:
European Airport Terminal: A major airport in Frankfurt installed 120 rolls (3,600 meters total) of the DC48V 30m COB strip 480 for its new terminal's ceiling coves. The 30m zero-voltage-drop design allowed single-run installation along the 28-meter-long corridors, eliminating the need for 72 additional power injectors and cutting wiring labor time compared to 24V COB strips. Brightness variation across the entire 30m run was measured at ≤2%, well below the industry average for long-run 24V COB Strip.
Cost-Saving for Large Installations:
or a 10,000-square-meter shopping mall in Dubai, using 30m rolls reduced connection points (vs. 5m standard COB strips), lowering the risk of wiring failures and reducing maintenance costs over 5 years. The mall's facilities manager reported zero brightness inconsistencies, even in 30m runs along the building's curved atriums.
Technical Edge:
The 30M/Roll No Voltage Drop Constant Current 480Led COB LED Strip integrates advanced constant current circuitry directly into the PCB, ensuring each 480chip/m segment receives stable power. This design outperforms traditional constant voltage strips, which require mid-run power taps to counter voltage drop-adding complexity and points of failure.
480chip/m Density & CRI>90: Dot-Free Uniform Glow with True Color Rendering
COB (Chip-on-Board) technology packs 480 LEDs per meter into an 8mm narrow PCB, creating a continuous light source with no visible dots or hot spots-a critical advantage for high-end architectural and commercial lighting.
Visual Aesthetics for Luxury Spaces: A 5-star hotel in the Maldives used the Warm White (3000K) DC48V 30m COB strip 480 to illuminate villa corridors and outdoor decks. The 480chip/m density delivered a soft, uniform glow that mimicked natural moonlight, while CRI>90 ensured that tropical foliage and interior decor retained their true colors.
Commercial Display Performance:
A luxury fashion boutique in Paris installed the Natural White (4000K) 30M Long DC48V COB Strip in its floor-to-ceiling display windows. The dot-free illumination highlighted fabric textures and color accuracy, with CRI>90 rendering even subtle hues correctly-leading to a increase in sales of premium apparel lines, as customers could better assess product quality.
Functional Lighting for Industrial Use:
A German automobile factory used the Cool White (6500K) DC48V 30m COB strip 480 for its 30-meter-long assembly lines. The uniform glow eliminated shadowed areas on workstations, reducing eye fatigue among workers and improving assembly precision-cutting defect rates.
DC48V Efficiency & Versatile IP Ratings: Safe, Energy-Saving & Adaptable
The DC48V voltage rating offers superior energy efficiency and safety compared to lower-voltage alternatives, while multiple IP ratings cater to indoor, outdoor, and wet environments.
Energy Efficiency:
With 85lm/w efficacy, the strip consumes just 8w/m- more efficient than traditional 24V COB strips (12w/m average). A municipal library in Madrid replaced outdated fluorescent tubes with the DC48V 30m COB strip 480, reducing annual lighting energy costs while increasing brightness.
Safety for Public Spaces:
DC48V operates at a lower current than 12V/24V systems, reducing fire risk and making it safer for installation in crowded areas like schools and hospitals. A primary school in London installed the IP65-rated DC48V 30m COB strip 480 in its outdoor playgrounds-low current and waterproof design ensured child safety, while the 30m run capability simplified installation around the 25-meter-wide play area.
IP Rating Versatility:
IP20 (indoor dry spaces like offices), IP65 (outdoor weather-resistant for building facades), and IP68 (fully submerged applications like fountains) cover lighting scenarios. A waterfront development in Barcelona used IP68-rated 30M Long DC48V COB Strip for underwater fountain lighting and IP65 for building lighting-one product line meeting all project needs and streamlining inventory for the contractor.
50cm Cutting Length & 8mm Narrow PCB: Flexible Installation for Irregular Spaces
While designed for 30m long runs, the DC48V 30m COB strip 480's 50cm cutting interval offers flexibility for custom-length projects, without sacrificing performance.
Irregular Space Adaptation:
A historic theater renovation in Rome used 600 meters of the DC48V 30m COB strip 480 to illuminate curved balconies and ornate ceiling details. The 50cm cutting length allowed installers to fit segments around architectural curves, reducing material waste(vs. 1m-cut strips) and preserving the theater's historic aesthetics. The 8mm narrow PCB fit into tight gaps between decorative moldings, where wider COB strips would have been visible.
On-Site Efficiency:
For a construction project in Singapore, installers cut 30m rolls into 7.5m segments for hotel room corridors-no on-site soldering required, as the 50cm cut marks aligned perfectly with room lengths.
♦ The DC48V 30M Ultra Long COB LED Strip Light 480's narrow profile and flexible cutting make it ideal for both large-scale runs and small custom applications, eliminating the need to stock multiple COB strip sizes for a single project.
Application
Shopping Malls & Retail Spaces: Ideal for ceiling coves, atriums, and display windows. A Dubai mall used the NW (4000K) DC48V 30m long COB strips480-30m runs eliminated power gaps, while CRI>90 enhanced product visibility.
Office Towers & Lobbies: The IP20 DC48V 30m long COB strips480 fits into narrow ceiling channels, providing soft ambient lighting. A London office tower installed-8w/m efficiency cut energy costs and the 30m run capability simplified installation across 28-meter-long lobbies.

FAQs
Q1: Can the DC48V 30M long COB strip be powered from both ends for even longer runs?
A: Yes-while designed for 30m single-end runs, powering from both ends extends the maximum run to 60 meters with ≤3% brightness DC48V 30M long COB strip. Our technical team provides custom wiring diagrams for ultra-long installations.
Q2: Is an external constant current driver required?
A: Yes-we recommend using our compatible DC48V constant current driver (sold separately) to ensure optimal performance. The driver is matched to the DC48V 30M long COB strip's 8w/m power draw, providing stable current for zero-voltage-drop operation.
Q3: Can the DC48V 30M long COB strip be dimmed?
A: Yes-it's compatible with PWM dimmers and smart lighting controllers (e.g., Alexa, Google Home). A luxury hotel in Paris used dimmable drivers to adjust brightness from 10–100%, creating different ambiances for daytime and evening events.
Q4: What is the minimum bending radius for installation?
A: The DC48V 30M long COB strip has a minimum bending radius of 5cm, making it suitable for curved surfaces like architectural arches and rounded display cases. Bending beyond this may damage the PCB and void the warranty.
Q5: How does the DC48V design compare to 24V COB strips for long runs?
A: DC48V reduces current by half compared to 24V (for the same power), minimizing energy loss and voltage drop. A 30m 48V run has ≤2% brightness variation, while a 30m 24V run typically has 15–20% variation-requiring 2–3 power injectors to compensate.
