IP68 is produced after the order is confirmed because it is not kept in stock, so a lead time of 12-15 days applies. Please tell us the required quantity, target delivery date and installation conditions, and we will confirm the production schedule for your project.
Lead times above are in calendar days and do not include shipping time. Shipping time depends on the destination and selected shipping method.
Why Choose HST-COB320 COB LED Strip
- True dot-free illumination — 320 LEDs/m COB construction produces a continuous light line without visible hotspots at a wide viewing angle.
- Efficient COB output — 8 W/m power density for uniform, energy-efficient linear lighting.
- Wide color temperature range — 2700K, 3000K, 4000K and 6000K options cover warm to cool white applications.
- CRI 90+ color rendering — Supports accurate color reproduction for retail, hospitality and residential specifications.
- Full IP range — IP20 to IP68 configurations cover dry indoor, damp-location and outdoor installations.
- Dual voltage flexibility — 12V and 24V options simplify procurement for mixed-infrastructure projects.
Typical Applications
HST-COB320 is designed for projects where uniform, dot-free linear lighting is required:
- Architectural linear lighting — Clean light lines for coves, recesses, façades and accent details.
- Cabinet and furniture lighting — Uniform illumination inside display cases, shelves and built-in furniture.
- Retail display lighting — Dot-free output for product showcases, shelves and visual merchandising.
- Hotel and hospitality lighting — Warm or neutral white accent lighting for guest areas, bars and lobbies.
- Commercial ceiling lighting — Continuous light lines for offices, corridors and common areas.
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.
12V vs 24V — Which One to Choose
Feature | 12V DC | 24V DC |
|---|---|---|
Cutting Unit | 25 mm | 50 mm |
Max Run (typical) | Shorter before power injection | Longer before power injection |
Power Supply | Easier to source for small projects | Better for long runs and lower current |
Best For | Short runs, DIY, small installations | Commercial projects, long linear runs |
Choose 12V for shorter runs and simpler power supply setups. Choose 24V for longer installations and reduced voltage drop over distance.
Quality & Documentation
HST-COB320 is manufactured with chip-on-board LED technology for uniform spectral output across the reel. CE and RoHS compliance documents can be provided for applicable product configurations upon request. Please tell us the target market and required configuration so the relevant documents can be checked. If LM-80/TM-21 lumen maintenance data is required, please confirm the requested configuration and application so availability can be verified.
Selection Tip
For first-time users of COB LED strips, we recommend requesting a sample reel of the IP20 configuration to evaluate dot-free uniformity, color temperature and CRI before committing to a larger order. This allows you to confirm that the 320 LEDs/m COB output meets your project's visual requirements.

FAQ
Q1: What is a COB LED strip, and how is it different from SMD strips?
COB (chip-on-board) LED strips mount multiple LED chips directly onto the PCB and cover them with a continuous phosphor layer. This creates a smooth, dot-free light line without the visible diode dots common on standard SMD strips. COB strips are preferred for applications where uniform light and clean appearance are important.
Q2: What is the difference between 12V and 24V versions?
Choose 12V if your installation is short, your power supply is already 12V, or you are using a simple controller. Choose 24V for longer runs, commercial installations or when you want to reduce current and voltage drop. The 12V version cuts every 25 mm; the 24V version cuts every 50 mm.
Q3: What is the cutting unit of HST-COB320?
The cutting unit is 25 mm at 12V and 50 mm at 24V. Always cut only at the marked cutting points to avoid damaging the circuit.
Q4: What is the maximum running length?
The maximum running length depends on the power supply capacity, voltage and wire gauge. At 8 W/m, 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.
Q5: What color temperatures are available?
HST-COB320 is available in 2700K, 3000K, 4000K and 6000K. 2700K-3000K is suitable for warm, comfortable spaces; 4000K-6000K is suitable for task-oriented, commercial or modern environments. Please confirm the required color temperature when requesting a quote.
Q6: What does CRI 90+ mean for my project?
CRI (Color Rendering Index) 90+ means colors under this light appear more accurate and natural compared with lower-CRI sources. It is recommended for retail displays, hospitality interiors, photography and residential spaces where color quality matters.
Q7: Can I request samples before bulk production?
Yes. Samples are available for evaluation. We recommend ordering a sample reel of the IP20 configuration to test dot-free uniformity, color temperature and CRI before placing a larger order. Please tell us the target specifications and application so the correct configuration can be prepared.
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 has a lead time of 5-7 calendar days; IP65 and IP67 have a lead time of 10-12 calendar days. 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 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.
Q10: Can you provide compliance documents?
CE and RoHS 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. If LM-80/TM-21 lumen maintenance data is required, please confirm the configuration so availability can be verified.
