Product Selection & Differences
Choosing the right LED solution depends on the application, installation method, environment, and desired lighting effect. LEMLUX COB LED strips are ideal for furniture lighting, under-cabinet illumination, retail displays, architectural details, and projects where smooth, dot-free light is important. Neon Flex solutions are commonly used for signage, decorative lighting, facades, outdoor projects, hospitality spaces, and premium visual installations where a continuous neon-style effect is required.
Whether you are designing residential interiors, commercial spaces, advertising projects, or custom lighting solutions, selecting the correct voltage, IP rating, color temperature, and LED density ensures optimal performance, reliability, and lighting quality. This section helps you understand the differences between COB LED strips, SMD strips, Neon Flex, and related accessories to choose the best solution for your project.
(01)
COB vs SMD vs Neon Flex – what should I choose?
- COB LED strip — smooth, dot-free light, ideal for interiors and visible installations
- SMD LED strip — more affordable, but with visible LED dots
- Neon Flex — fully diffused light, ideal for signage and outdoor use
(02)
When should I choose COB instead of Neon Flex?
Choose COB when:
- You need higher efficiency
- Installation is hidden or in profiles
- You want better price/performance
Choose Neon Flex when:
- The strip is visible
- You need outdoor durability
- You want a "neon line" effect
(03)
Can COB LED strips be used as main lighting?
Yes, but only high-power models (~2000–3000 lm/m).
(04)
What LED density is best?
- 480–784 LEDs/m (COB) → optimal
- Lower density → less uniform light
(05)
What color temperature should I choose?
- 2700K–3000K → warm
- 4000K → neutral (most popular)
- 6000K+ → cool
(06)
What is CRI and why is it important?
- CRI >80 → standard
- CRI >90 → high-quality color rendering
(07)
Why do COB LED strips look better than standard LED strips?
- No visible dots
- Continuous light line
- Better diffusion
Power & Installation
Proper power selection and installation are essential for stable LED lighting performance, long lifespan, and safe operation. Factors such as voltage (12V, 24V, or 48V), cable length, power supply capacity, voltage drop, and cooling all affect the final result of an LED installation.
LEMLUX LED strips and Neon Flex solutions are designed for a wide range of applications including furniture lighting, commercial projects, retail displays, signage, architectural lighting, and custom interior solutions. This section explains how to choose the correct power supply, recommended installation lengths, wiring methods, dimming options, and required accessories to ensure reliable and professional operation.
(01)
Should I choose 12V, 24V, or 48V LED strips?
- 12V — short runs
- 24V — standard choice
- 48V — long runs
(02)
How long can I run an LED strip without voltage drop?
- 12V → 3–5 m
- 24V → 5–10 m
- 48V → up to 20 m
(03)
Why is my LED strip less bright at the end?
This is caused by voltage drop.
Solutions:
- Use 24V or 48V
- Power from both ends
- Reduce run length
Recommended max length:
- 12V → 3–5 m
- 24V → 5–10 m
- 48V → up to 20 m
(04)
What power supply should I use?
Total wattage + 20–30% reserve.
Example:
10 m × 10 W/m = 100 W → use a 120–130 W PSU.
(05)
Can I connect LED strips without soldering?
Yes, using connectors.
- Soldering = more reliable
- Connectors = faster
(06)
What accessories are required?
- Power supply
- Controllers
- Connectors / soldering tools
- Aluminum profiles
(07)
Do I really need an aluminum profile?
Yes, for:
- Cooling
- Longer lifespan
- Clean installation
Protection & Durability
LED lighting performance and lifespan strongly depend on installation quality, environmental conditions, cooling, and protection level. Choosing the correct IP rating is essential for indoor, humid, or outdoor applications. LEMLUX LED strips and Neon Flex solutions are designed for reliable operation in residential, commercial, signage, and architectural lighting projects.
Proper heat dissipation, suitable power supplies, aluminum profiles, and correct wiring help prevent overheating, voltage drop, and premature failure. This section explains how to select the right protection level, how LED strips perform in demanding environments such as outdoor or high-temperature areas, and how to maximize durability and long-term reliability.
(01)
What IP rating do I need?
- IP20 — indoor
- IP65 — humid areas
- IP67 — outdoor
(02)
Is Neon Flex waterproof?
Yes, most models are IP67:
- Rain resistant
- Dustproof
- Outdoor suitable
(03)
Can LED strips be used in sauna or high heat?
Only special high-temperature COB strips (rated ~105–115 °C).
(04)
Why is my LED strip overheating?
- No aluminum profile
- Too high a load
- Bad power supply
(05)
Why did my LED strip stop working?
- Weak PSU
- Wrong wiring
- Moisture
- Poor connections
Handling & Installation Limits
LED strips and Neon Flex products are flexible, but they still have mechanical and installation limitations that must be considered during planning and installation. Excessive bending, incorrect mounting surfaces, poor heat dissipation, improper cutting, or unsuitable power connections may reduce performance, damage components, or shorten product lifespan.
COB LED strips are designed for smooth and professional lighting applications, but they should not be sharply bent, twisted, or folded. Neon Flex solutions provide greater flexibility and are ideal for curved installations, signage, and decorative applications, although most models are designed to bend only in a specific direction depending on their construction.
This section explains practical installation limitations, recommended bending practices, maximum run lengths, connector usage, mounting methods, and common installation mistakes to help ensure safe, reliable, and long-lasting LED lighting installations.
(01)
Can I bend COB and Neon Flex freely?
- COB — limited flexibility
- Neon Flex — flexible, but usually one direction only
