Why Choose HST-COB528 COB LED Strip
- Dot-free illumination — COB technology eliminates individual LED hotspots, delivering a smooth, continuous line of light ideal for reflective surfaces and close-range viewing.
- Ultra-high LED density — 528 LEDs/m provides exceptional uniformity with no visible gaps between light-emitting areas.
- Dual voltage flexibility — Both 12V and 24V DC options allow integration into existing power systems or new installations.
- CRI 90+ color rendering — Ra 90+ ensures accurate color representation for retail displays, hospitality and residential applications.
- 10mm PCB compatibility — Standard 10mm width fits most aluminum profile channels for professional recessed or surface-mounted installations.
Typical Applications
HST-COB528 is designed for applications where smooth, dot-free linear lighting with high color accuracy is essential:
- Cabinet and under-cabinet lighting — COB technology eliminates hotspots on glossy cabinet surfaces and countertops.
- Retail display lighting — CRI 90+ ensures products are shown in accurate, appealing colors without distracting dot patterns.
- Hospitality lighting — Hotel rooms, reception desks, bars and restaurants requiring warm, uniform ambient light.
- Furniture lighting — Integrated into shelves, wardrobes and display units where the light source may be visible at close range.
- Architectural cove and recessed lighting — The 10mm PCB fits standard aluminum profile channels for clean, professional installations.
For outdoor or wet-area applications, select the appropriate waterproof configuration and confirm sealing method, connectors, installation conditions, quantity and lead time before ordering. Note that IP68 is produced to order and is not kept in stock, so a lead time of 12-15 days should be allowed.
COB vs SMD LED Strip — Which One to Choose
Feature | COB (This Product) | SMD (e.g., SMD2835/SMD3528) |
|---|---|---|
Light Appearance | Smooth, dot-free line of light | Individual LED dots visible at close range |
LED Density | Up to 528 LEDs/m | Typically 60–240 LEDs/m |
CRI | Typically Ra 90+ | Typically Ra 80+ (Ra 90+ available on select models) |
Heat Distribution | Even across COB surface | Concentrated at each SMD chip |
Best For | Close-range viewing, reflective surfaces, premium applications | General lighting, cost-sensitive projects, longer runs |
Price | Higher due to denser chip arrangement | More economical per meter |
Choose COB when the light source may be visible and you need the smoothest possible output. Choose SMD when you need a cost-effective solution for general illumination where the light source is hidden in a profile or diffuser.
Quality & Documentation
- Each reel is tested before shipment to verify light uniformity, color consistency, CRI performance and power consumption.
- Compliance documents can be provided for applicable product configurations upon request. Please tell us the target market and required product configuration so the relevant documents can be checked.
Selection Tip
For first-time users of COB LED strips, we recommend requesting a sample reel of the IP20 configuration to evaluate the dot-free light output, color temperature and CRI 90+ performance before committing to a larger order. This allows you to confirm that the COB technology meets your project's visual quality requirements.

Looking for a dot-free COB LED strip with ultra-high LED density for your lighting project?
Send us your required specifications: voltage, color temperature, IP rating, approximate length and quantity. Our team will review your requirements and help you evaluate a suitable configuration for your project. There is no minimum order quantity. If your project requires the IP68 configuration, please allow a lead time of 12-15 days for production.
OEM / Customization
OEM/ODM options may include color temperature, CRI, IP protection rating, cable type and length, connector type, packaging and private labeling, subject to technical feasibility and order quantity. Please share your project specifications and application details for evaluation.
FAQ
Q1: Can I request COB LED strip samples before bulk production?
Yes. Samples are available for evaluation. We recommend ordering a sample reel of the IP20 configuration to test the dot-free light output, color consistency, CRI 90+ performance and compatibility with your aluminum profiles before placing a larger order. Please tell us the target specifications and application so that the correct configuration can be prepared.
Q2: What customization options are available for COB LED strips?
Customization options may include color temperature, CRI, IP protection rating, cable type and length, connector type, packaging and private labeling. Customization is subject to product feasibility, order quantity and project requirements. Please share your project specifications and application details for evaluation.
Q3: What is the maximum running length of HST-COB528?
The maximum running length depends on the voltage, power supply capacity and wire gauge. At 12V DC with 14 W/m power consumption, voltage drop occurs more quickly than at 24V. At 24V DC, longer runs are possible before power injection is needed. Please tell us your planned installation length and voltage so that we can advise on power supply requirements and whether multiple power injection points are needed for your project.
Q4: What applications are suitable for HST-COB528?
This product is designed for applications requiring smooth, dot-free linear lighting with excellent color rendering and high LED density: cabinet and under-cabinet lighting, retail displays, hospitality interiors, furniture integration and architectural cove lighting. The COB technology eliminates visible LED dots, making it ideal where the light source is visible at close range or on reflective surfaces.
Q5: What is the difference between COB and SMD LED strips?
COB (Chip on Board) technology mounts multiple LED chips directly onto a single substrate, creating a smooth, dot-free line of light with typically higher CRI. SMD (Surface Mount Device) technology uses individual LED packages mounted at intervals, which may show visible dots at close range but offer a more economical solution for general lighting. COB generally has higher LED density and more even heat distribution. See the comparison table above for details.
Q6: Is HST-COB528 available in both 12V and 24V?
Yes. Unlike some COB models that are 24V only, HST-COB528 is available in both 12V and 24V DC configurations. Please note that 12V configurations have a shorter maximum running length due to higher current and voltage drop over distance. If your installation requires longer runs without additional power injection, 24V is recommended.
Q7: Can you provide compliance documents?
Compliance documents can be provided for applicable product configurations upon request. Please tell us the target market and required product configuration so the relevant documents can be checked.
Q8: Is there a minimum order quantity, and how long does production take?
There is no minimum order quantity for this product. Small quantities can be ordered for testing, samples or project use in any IP configuration. IP20, IP65 and IP67 are standard configurations with lead times of 5-7 days and 10-12 days respectively. IP68 is not kept in stock and is produced to order, with a lead time of 12-15 days. Please tell us the required quantity and your target delivery date so that the production schedule can be confirmed.
Q9: Is the IP68 version in stock, or does it have to be produced?
IP68 is not kept in stock and is produced to order. There is no minimum order quantity for IP68, so small quantities can be produced for evaluation. Production takes 12-15 days after order confirmation. If you need the fastest possible delivery for an initial test, we recommend ordering the IP20, IP65 or IP67 configuration first to evaluate light performance and color consistency.
