How to Choose the Right COB LED Strip Light
Choosing the right COB LED strip light involves more than selecting the brightest product.
For a professional installation, you should consider voltage, wattage, colour temperature, CRI, IP rating, LED density, installation location and control system.
1. Choose the Correct Voltage
COB LED strips are commonly available in 12V or 24V DC configurations.
For longer runs, 24V systems are often preferred because they can help reduce voltage-drop problems compared with equivalent lower-voltage systems, although the actual installation still needs to be designed according to the strip’s electrical specifications.
Always select a compatible constant-voltage LED driver.
2. Select the Correct Wattage
LED strip wattage is normally specified per metre.
For example:
- 5W/m
- 10W/m
- 14W/m
- 20W/m
Higher wattage does not automatically mean better lighting.
The required wattage depends on the application, desired brightness and installation method.
For every project, calculate the total power requirement before selecting the driver.
3. Choose the Right Colour Temperature
Colour temperature is measured in Kelvin (K).
Typical options include:
2700K – Warm and decorative
3000K – Warm white
4000K – Neutral white
5000K – Cool/neutral daylight
6000K–6500K – Cool white
For homes and hospitality environments, warmer colour temperatures are often selected for a comfortable atmosphere.
Retail, offices and commercial applications may require a more neutral appearance.
4. Consider CRI
CRI (Colour Rendering Index) describes how accurately a light source renders colours compared with a reference light source.
High-CRI LED lighting can be particularly valuable in applications where accurate colour appearance matters, including retail, galleries, hospitality and premium residential interiors.
For premium projects, look for COB LED strips with CRI 90+ or higher where colour quality is important.
5. Select the Correct IP Rating
The environment determines the required IP rating.
For dry indoor applications, an IP20 LED strip may be appropriate.
For areas exposed to moisture, water-resistant or waterproof LED strip products may be required.
Do not select an IP rating based only on appearance; consider the actual installation environment.
6. Consider RGB, RGBW or RGB+CCT
COB LED strips are not limited to single-colour white light.
Depending on the product, you can select:
- Single colour
- Tunable white / CCT
- RGB
- RGBW
- RGB+CCT
RGB+CCT COB LED strip can be particularly useful when one lighting system needs both colour-changing effects and adjustable white light.
7. Use an Aluminium LED Profile
For many professional installations, COB LED strip can be installed inside an aluminium LED profile with a diffuser.
The profile can provide:
- A professional finished appearance
- Physical protection
- Heat spreading
- A mounting surface
- Diffuser compatibility
- Better control of the finished light
The profile and LED strip should be selected as a complete lighting system rather than independently.
8. Calculate the Driver Size
Suppose a project uses:
10 metres × 20W/m = 200W
The LED driver should not simply be selected at exactly 200W. Appropriate capacity/headroom should be allowed according to the manufacturer’s specifications and installation conditions.
Also consider:
- Cable length
- Voltage drop
- Number of power feeds
- Maximum continuous run
- Controller requirements
- Dimming method
These factors become increasingly important on longer LED strip installations.
9. COB LED Strip Applications
COB LED strips can be used for:
Residential
- Kitchens
- Bedrooms
- Living rooms
- Wardrobes
- Stairs
- Joinery
Commercial
- Retail stores
- Showrooms
- Hotels
- Restaurants
- Offices
- Displays
Architectural
- Recessed profiles
- Ceiling coves
- Feature walls
- Linear lighting
- Custom aluminium profiles
Conclusion
The best COB LED strip is not necessarily the highest-wattage or highest-density product.
A professional result comes from matching the COB strip, power supply, aluminium profile, diffuser and control system to the application.
At Vesta Lines, COB LED strip lighting can be specified for residential, commercial and architectural lighting projects, including custom lengths, RGB+CCT, dimmable systems and aluminium profile installations.
