What Is a COB LED Strip Light?

COB (Chip On Board) LED technology packs hundreds of tiny LED chips closely together. This design creates a High Brightness Long LED Strip with no visible dots or gaps — just a clean, uniform glow. Even in exposed or shallow spaces, the light stays smooth and even.

Why Choose COB LED Long Strip Light Designs?

FAQs 

How do extra long COB strips (20–30 m) maintain uniform brightness using 24 V constant-current or 48 V designs?

They use higher operating voltage or internal constant-current regulation to reduce current flow, which minimises voltage drop and keeps brightness consistent across long runs.

When should designers choose 48 V ultra-long COB strips over standard 24 V 5 m reels for commercial coves and corridors?

48 V COB strips are preferred when seamless runs beyond 15–20 m are required, as they reduce power injection points, cable thickness, and installation complexity.

What driver sizing and power-injection rules apply when running 30 m of 48 V COB strip from a single feed?

Drivers should be sized with 20–30% headroom, and many 48 V COB strips can run close to 30 m from one feed depending on wattage, with power injection only needed at higher loads.

How do 240 V AC extra-long COB strips (up to 50 m) compare with 48 V DC COB in safety, flicker, and application scope?

240 V AC COB strips allow very long runs but require stricter electrical compliance and can introduce flicker, while 48 V DC offers safer low-voltage operation and smoother dimming control.

What lengths and maximum continuous runs are available for extra long COB strips?

Extra long COB strips are commonly available in 10 m, 20 m, and 30 m reels, with some AC-powered versions extending up to 50 m in a single continuous run.

What power supply options are suitable for 24 V versus 48 V long COB runs?

24 V systems typically require multiple drivers or injection points on long runs, while 48 V systems allow fewer, higher-voltage drivers with lower current draw.

How do you wire a 50 m COB strip to avoid voltage drop?

For very long runs, centre-feed or dual-end feeding is recommended, along with appropriate cable sizing and voltage selection to keep losses within limits.

What waterproofing methods are recommended for outdoor extra long COB installations?

Outdoor installs should use IP67 or IP68 rated COB strips with sealed end caps, waterproof connectors, and silicone-protected joints.

Which controllers are compatible with RGB and CCT extra long COB strips?

Extra long RGB and CCT COB strips typically pair with constant-voltage controllers from systems such as MiBoxer or Skydance, selected to match strip voltage and channel type.

How do 24 V and 48 V extra long COB strips maintain uniform brightness over 10–30 m runs without visible voltage drop?

They rely on higher voltage operation, reduced current flow, and in some designs internal current balancing to maintain even output along the entire length.

What is the practical longest run length for extra long COB strips before power injection or dual-feed wiring is required?

Depending on wattage and voltage, practical single-feed runs range from around 10–15 m at 24 V to 25–30 m at 48 V before additional feeding is needed.

How does constant-current versus constant-voltage design affect 20–30 m COB reels?

Constant-current designs actively regulate output to prevent brightness drop, while constant-voltage designs rely more on higher voltage and careful wiring to manage losses.

When should designers specify extra long COB strips instead of standard 5 m rolls?

Extra long COB strips are ideal when uninterrupted lines of light are required, reducing visible joins and installation time in corridors, retail aisles, and large coves.

How do extra long COB strips simplify ceiling detail lighting compared with traditional join-heavy layouts?

They eliminate frequent solder joints and connectors, resulting in cleaner aesthetics, fewer failure points, and faster installation.

What advantages do 48 V extra long COB strips offer for façade outlines compared with 230–240 V AC COB solutions?

48 V systems provide safer low-voltage operation, better compatibility with dimming and control systems, and more stable light output.

How do you size LED drivers for 20–30 m extra long COB strips while keeping voltage drop within limits?

Total wattage is calculated by length and W/m, then drivers are oversized by 20–30% and matched with appropriate cable gauge to minimise losses.

What wiring topologies are recommended for ultra long COB runs?

One-end feed works for moderate lengths, while centre-feed or dual-end feed is preferred for longer runs to balance voltage and brightness.

Which IP ratings, profiles, and accessories are best for protecting extra long COB strips indoors and outdoors?

IP20 suits indoor dry areas, IP67/IP68 for outdoor use, combined with aluminium profiles, silicone diffusers, sealed end caps, and corrosion-resistant clips.

What is an Extra Long COB LED Strip?

An extra long COB LED strip is a continuous-length strip, typically 10–30 m or more, designed to deliver uniform, dotless light without frequent power injection.

What are the typical lengths of extra long COB LED strips?

They are commonly produced in 10 m, 20 m, and 30 m reels, with some AC variants extending up to 50 m.

Why are COB LED strips superior to traditional LED strips?

COB strips provide continuous, dot-free illumination, better colour consistency, and smoother light distribution than standard SMD LED strips.

Are extra long COB LED strips suitable for outdoor use?

Yes, when specified with IP67 or IP68 protection and installed using proper sealing and mounting accessories.

What applications are extra long COB strips typically used for?

They are widely used in hotel corridors, commercial coves, retail aisles, office ceilings, and architectural façade outlines.
