Frequently Asked Questions
24V COB LED Strip Light FAQs
What is a 24V COB LED Strip Light?
A 24V COB (Chip-on-Board) LED Strip Light is a flexible LED strip that uses closely packed LED chips to produce a smooth, continuous line of light without visible hotspots.
What are the advantages of 24V over 12V LED strips?
24V LED strips experience less voltage drop, making them ideal for longer runs with more consistent brightness. They also require lower current, which can reduce cable size requirements in some installations.
How long can I run a 24V COB LED Strip?
Most 24V COB LED strips can be installed in runs of up to 10 metres before power should be injected or additional strips connected in parallel. Always refer to the product specifications.
Can I cut a 24V COB LED Strip?
Yes. The strip can only be cut at the designated cut marks, which are typically every 50mm on most 24V COB LED strips.
Can I dim a 24V COB LED Strip?
Yes. Simply use a compatible 24V LED dimmer or controller designed for the strip's wattage and voltage.
What power supply do I need?
Use a 24V DC constant voltage LED power supply with a minimum of 20% spare capacity above the total wattage of your LED strip installation.
Can I install the strip outdoors?
Yes, provided you choose a waterproof IP-rated version (such as IP65, IP67, or IP68) and ensure all connectors and power supplies are suitably protected from moisture.
Do I need an aluminium profile?
While not essential, an aluminium LED profile is highly recommended. It improves heat dissipation, protects the strip from damage, and provides a clean, professional finish.
Can I install the strip myself?
Yes. Most DIY users can install a 24V COB LED Strip using the correct power supply and accessories. However, if mains wiring is required, it should be carried out by a qualified electrician.
Can I connect multiple strips together?
Yes. Multiple strips can be connected, but for installations longer than 10 metres, additional strips should be connected in parallel rather than extending one continuous series run.
Why is my LED strip dim at the end?
This is usually caused by voltage drop. The solution is to inject power at additional points or split the installation into multiple parallel runs.
Can I bend the strip around corners?
The strip is flexible but should not be sharply bent, folded, or twisted. Observe the manufacturer's minimum bend radius to avoid damaging the LEDs or circuit board.
How long do COB LED Strip Lights last?
Quality COB LED strips typically have a lifespan of 30,000–50,000 hours, depending on operating conditions, heat management, and power supply quality.
Can I shorten and reconnect the strip?
Yes. After cutting at the marked cut points, the strip can be reconnected using compatible strip connectors or by soldering the connection.
Why choose a 24V COB LED Strip?
24V COB LED strips provide smooth, dot-free illumination, improved efficiency on longer runs, reduced voltage drop, excellent flexibility, and a professional lighting finish, making them ideal for residential, commercial, retail, and architectural lighting projects.
Are LED strip lights waterproof?
LED strip lights are available in different IP ratings to suit both indoor and outdoor applications. Non-waterproof IP20 strips are ideal for indoor use, while waterproof options such as IP65, IP67, and IP68 are designed for outdoor, damp, or exposed environments.

Installation & Setup
24V COB LED Strip Light Installation & Setup
Installing a 24V COB LED Strip Light is straightforward when the correct components are used.
Step 1: Plan Your Installation
Measure the installation area, determine the total strip length required, and calculate the total wattage to select a suitable 24V DC power supply with at least 20% spare capacity.
Step 2: Prepare the Mounting Surface
Ensure the surface is clean, dry, and free from dust or grease. For the best performance and longest lifespan, install the strip inside an aluminium LED profile.
Step 3: Cut the Strip (If Required)
Only cut the LED strip at the marked cut points. Cutting elsewhere may damage the strip.
Step 4: Connect the Strip
Connect the strip to the 24V DC power supply using compatible LED strip connectors or by soldering the wires to the copper pads. Always observe the correct polarity (+ and –).
Step 5: Test Before Mounting
Power the strip briefly to confirm all sections illuminate correctly before permanently fixing it in place.
Step 6: Secure the Strip
Remove the adhesive backing and press the strip firmly onto the mounting surface or into the aluminium profile. Avoid excessive bending or twisting during installation.
Step 7: Connect to Power
Connect the power supply to the mains according to local electrical regulations. If you're unsure about mains wiring, consult a qualified electrician.
Installation Tips
- Avoid sharp bends and do not exceed the minimum bend radius.
- Use aluminium profiles to improve heat dissipation and maximise LED lifespan.
- Inject power at multiple points for longer installations to minimise voltage drop.
- Do not power the strip while it is still tightly wound on the reel.
- Choose an IP-rated strip suitable for the installation environment, especially in damp or outdoor locations.
Following these steps will help ensure reliable performance, consistent brightness, and a long service life from your 24V COB LED Strip Light installation.
