Introduction

Single color COB Strips 312leds/m has two advantages: roll to roll PCB design and 10 meter no voltage dropping. Over 5 meters, traditional COB strips is volt dropping and brightness different if Over 5 meters. Single color COB strips 312leds/m maintain uniform and consistent lighting output throughout the entire 10 meter operation without the need for additional wiring to connect to the power supply. Single color COB Strips 312leds/m is designed to handle the most important commercial, residential, and outdoor projects for reliability and consistency.

Roll to roll PCB: 10 meter consistent lighting
Most COB strips use segmented PCBs, which generate voltage drops (dimming) when installed over 5 meters, you need to add power every 5 meters. The roll to roll design of Single color COB Strips 312leds/m has changed this:
A single continuous flexible PCB can ensure uniform current distribution within a range of 10 meters. In third-party testing, after running at full load (11W/m) for 72 hours, the brightness change of Single color COB Strips 312leds/m remained below 2% (segmented bars were 15-20%).
Fewer solder joints can reduce the risk of failure, which is crucial for high traffic areas such as retail display cabinets or hotel lobbies.
For a 50 meter long office lobby project, this means 5 runs (10 meter Single color COB Strips 312leds/m each) instead of 10 runs (each 5-meter COB strip) - reducing installation time and saving wiring materials.


High density chip and 180 °beam angle achieve perfect uniformity
312 microchips per meter, Even within a viewing distance of 8 centimeters, there is no visible gap between the LEDs, making Single color COB Strips 312leds/m ideal for cabinet lighting, museum exhibitions, or retail shelves, as clarity at close range is crucial.
The 180 °beam angle balances the focus and coverage range. Install it 10-15cm away from the wall to achieve a complete "washing" effect, or use it on the ceiling of the restaurant to illuminate tables without hotspots.
The efficiency of 100lm/W can provide 1100 lumens/m, while saving energy compared to standard 15W/m COB strips.


Flexible PCB suitable for any space
Single color COB Strips 312leds/m designed to adapt to curved or narrow spaces: CRI90 2700K/3000K/4000K/6000K option
The slim width of 8mm is suitable for gaps between cabinets, along decorations, or inside LED alu profiles - no longer requiring the laborious use of LED strips.
The minimum bending radius is 3cm, allowing it to move along circular walls, display cabinets, or stair handrails without damaging the PCB.
All day performance: Reliable operation within a temperature range of -25 ℃ (cold winter storefront) to 60 ℃ (hot kitchen tailgate) - without darkening or cracking at extreme temperatures.


Multi functional protection and easy installation
IP rating options: IP20 (for dry indoor spaces such as bedrooms/offices), IP65 (for splash proof kitchens/covered terraces), or IP67 (for waterproof swimming pool edges/outdoor signage).
Tool free installation: Industrial grade 3M VHB tape can bond to wood, metal, glass, or ceramic tiles in seconds. It has no residue and can maintain adhesion for more than 3 years even in high humidity bathrooms.
Precise cutting: Trim to the desired length at intervals of 19.23mm (DC12V) or 38.46mm (DC24V). For example, a 2.3-meter-deep cabinet can be cut from a 10 meter long Single color COB Strips 312leds/m without any waste.
Applications

◆ Retail store renovation: a clothing chain store in Chicago has installed 4000K IP65 Single color COB Strips 312leds/m (10m each) to illuminate french window. The 10 meter no voltage drop eliminates additional power supply, and the uniform light makes clothing colors popular (CRI ≥ 90).
◆ Hotel lobby lighting: A four-star hotel in Miami used long 3000K IP20 Single color COB Strips 312leds/m on its curved lobby ceiling. Flex COB strips seamlessly curve around an arc, avoiding dimming with a 10 meter travel. The customer survey rated the 'lighting atmosphere' as 4.8/5 (higher than the previous 3.2/5 for halogen systems).


◆ Outdoor Fountain Accent: A public park in Seattle installed 6000K IP67 Single color COB Strips 312leds/m around its central fountain. The IP67 protection withstood constant splashing, and 10-meter runs simplified wiring. Evening visitors increased, as the bright, uniform light made the fountain a safe, inviting focal point.
Certifications: CE (compliant with EU safety standards EN 61347) and ROHS (free of lead, mercury, and harmful substances) certified, ensuring compliance for global projects.

▼ Automated Production: Manufactured in our ISO9001-certified facility using SMT (Surface Mount Technology) machines for precise chip placement. Defect rates are below 0.1%-far lower than the industry average of 1–2%.
Rigorous Testing: Each COB strips undergoes:
- 72-hour full-load aging tests to check stability.
- IP rating verification (water/dust exposure for outdoor models).
- Voltage drop testing (10-meter runs at full power).
- Color temperature calibration (±50K) to ensure consistency.

FAQs
Q: Can this COB strip be dimmed?
A: Yes. It's compatible with 0-10V, PWM, or DALI dimmers (rated for 12V/24V LED strips). We recommend our PWM dimmer for smooth dimming from 100% to 1% brightness-no flicker or color shift.
Q: What's the maximum run length for DC12V vs. DC24V?
A: 10-meter runs (zero voltage drop)
Q: Is the 3M tape removable?
A: Yes. It peels off without leaving residue, but it's not reusable. For permanent installations, clean the surface with alcohol before applying to maximize adhesion.
Q: Can it be used with smart home systems?
A: Yes. Pair it with a Tuya/Smart Life WiFi controller (sold separately) to control brightness via app or voice (Alexa/Google Home). Perfect for residential or hotel projects wanting smart functionality.
