2. Selection Tip
12V or 24V – Which Version Should You Choose?
Both 12V and 24V versions are available. The suitable option depends on the required cutting length, installation distance and power supply configuration.
12V Version
- 22.73 mm cutting unit
- Suitable when shorter cutting increments are required
- Provides greater flexibility for customized installation lengths
24V Version
- 45.45 mm cutting unit
- Operates at lower current than the 12V version at the same power level
- Generally preferred for longer linear lighting installations where reducing voltage drop is important
For longer continuous runs, the final installation length should be evaluated according to PCB resistance, cable size, power-feed position, power consumption and installation conditions.
Important IP65 Application Note
IP65 protection is suitable for installations where the LED strip may be exposed to moisture, dust or occasional water splashing under appropriate installation conditions.
For moisture-prone applications, cut ends, cable outlets, joints and connectors should be properly sealed to maintain the required protection.
IP65 LED strip should not automatically be considered suitable for continuous water immersion or underwater applications. For more demanding environments, please provide the actual installation conditions so HST Light can recommend an appropriate waterproof solution.
3. Why Choose HST-COB528-IP65?
528 LEDs/m High-Density COB Design
The high-density COB structure creates a more continuous lighting effect with reduced visible LED spotting compared with conventional lower-density SMD LED strips.
It is especially suitable for applications where the light source may be visible or where smooth linear illumination is required.
Ra90+ High Color Rendering
With CRI Ra90+, the strip provides improved color appearance for environments where visual quality matters.
It is well suited for:
- Retail lighting
- Hospitality projects
- Residential lighting
- Display lighting
- Commercial interiors
- Architectural applications
Smooth Linear Illumination
COB technology integrates a high number of LED chips into a continuous light-emitting surface, helping create a smoother line of light.
When installed in a suitable aluminum profile, it can provide a clean and professional linear lighting appearance.
IP65 Protection
The IP65 version provides additional protection for installations exposed to moisture, dust and occasional water splashing.
This makes it suitable for indoor applications requiring extra protection as well as selected protected outdoor installations.
12V and 24V Options
Two voltage options allow buyers to select the appropriate version according to cutting requirements, installation length and power distribution design.
Precise Cutting Units
- 12V: 22.73 mm
- 24V: 45.45 mm
The defined cutting units help contractors and project customers plan customized installation lengths more accurately.
OEM / ODM Customization Support
HST Light supports project-based customization for distributors, wholesalers, contractors, lighting brands and OEM customers.
Available options include PCB, voltage, CCT, CRI, power, length, waterproof requirements, cable, connector and packaging.
4. Typical Applications

8. FAQ
Q1: What is the difference between COB LED strip and traditional SMD LED strip?
COB LED strip uses a high-density chip-on-board structure to create a more continuous light-emitting surface.
Compared with conventional lower-density SMD LED strips, COB technology can help reduce visible LED spotting and provide a smoother linear lighting effect.
This makes COB LED strip particularly suitable for visible linear lighting, aluminum profile installations and decorative applications requiring a clean appearance.
Q2: What is the CRI of HST-COB528-IP65?
The standard HST-COB528-IP65 version is Ra90+.
High CRI helps improve the visual appearance of illuminated objects and is particularly useful for:
- Retail stores
- Hotels
- Residential interiors
- Displays
- Commercial spaces
- Architectural lighting
If your project has a specific CRI requirement, please provide the target specification when requesting a quotation.
Q3: Can HST-COB528-IP65 be used outdoors?
The IP65 version is suitable for moisture-prone environments and selected protected outdoor installations.
However, the complete installation system must be considered. Cable outlets, connectors, joints and cut ends should be correctly sealed where water exposure may occur.
For continuous water immersion or more demanding outdoor conditions, please provide the actual application environment so that a more suitable waterproof solution can be evaluated.
Q4: Can the voltage, CCT, CRI and length be customized?
Yes.
OEM/ODM options can include:
- PCB design
- Voltage
- Color temperature
- CRI
- Power
- Strip length
- Waterproof requirement
- Cable length
- Connector type
- Packaging and labeling
For special specifications, sample development and testing may be recommended before mass production.
Q5: What is the cutting unit of HST-COB528-IP65?
The cutting unit depends on the voltage version:
- 12V: 22.73 mm
