RGB COB LED Strip Light Seamless Color‑Changing Tape For Ambient Decoration

1. Product Overview — Seamless RGB COB Color-Changing Tape

The RGB COB LED Strip Light is a premium seamless color-changing tape engineered for ambient decoration in bars, lounges, home cinemas, living rooms, retail windows and hospitality interiors. It combines a 10mm white PCB, 480 LEDs per meter chip-on-board (COB) architecture and a soft continuous phosphor coating to deliver one of the most uniform, dot-free light lines available on the market today.

Unlike traditional SMD RGB strips that show visible dot points and harsh glare, this COB tape emits a silky, continuous light beam with no gaps, no hotspots and no visible pixels — the light looks like a solid luminous band rather than a row of individual LEDs. This makes it the ideal choice for architects, interior designers and lighting contractors who demand a premium "light line" look for their projects.

• True full-color RGB — 16 million color combinations with smooth 0-100% dimming

• 480 LEDs/m ultra-high density — completely dot-free seamless light

• DC24V safe low-voltage system — safer for indoor wood, fabric and furniture

• 15W/m continuous power — balanced brightness with energy efficiency

• Cut every 50mm — precise length control for any installation

• IP20 to IP68 options — indoor bare, silicone-coated or fully waterproof

• No CRI specification — decorative grade, engineered for effect lighting

2. Technical Specifications — Exact Numbers You Can Plan With

Please note: this decorative-grade RGB product does not publish a CRI index. If you need high color-rendering white light, please select our tunable white CCT COB series instead.

3. Real Light Performance — See the True 480 LEDs/m Dotless Line

This is a real photo of the strip powered on. Three identical strips are shown in pure red, pure green and pure blue — proving the even, continuous light output across the full color gamut. The light surface is a soft diffused band with zero visible pixel points, exactly how the tape looks when installed.

Because the RGB chips are packed at 480 per meter under a continuous phosphor layer, color transitions are buttery smooth. When running dynamic modes — rainbow flow, breathing, strobe, chase, or music sync — there are no color gaps between adjacent chips. The result is a professional-grade animated light effect that looks equally good in a 5-star bar and a cozy home TV backlight.

• 16 million static colors selectable via controller

• 20+ built-in dynamic modes on most RGB controllers

• 0-100% stepless dimming without flicker on quality controllers

• Consistent brightness along 5m reels (low voltage drop design)

4. Application — Bar & Hospitality Scene

In this real installation photo, the RGB COB tape glows along a bar counter and back bar, flooding the marble and bottle shelves with vibrant color that instantly upgrades the venue's atmosphere. The continuous light line — free of dots and dark spots — is exactly what makes COB the first choice for commercial hospitality projects where the fixture itself is visible.

Perfect for:

• Bar counters, back bars, liquor shelves and under-bar toe-kick lighting

• KTV rooms, nightclubs, lounge seating coves and DJ booth accents

• Restaurant ceiling coves, buffet display lighting and wall washing

• Home cinema screens, TV backlighting, sofa cove lighting and stair accents

• Bedroom headboard glow, wardrobe interior lighting and makeup mirror surrounds

• Retail storefronts, window displays, exhibition booths and event stages

IP65/IP68 versions can be used outdoors — patio bars, garden pergolas, poolside coves and facade accents — where moisture resistance is required.

5. Installation & Wiring Guide — Minimal & Clean

Wiring is simple and clean with four connections: +DC24V, R, G, B. Follow this order:

1. Power supply — use a DC24V constant-voltage driver (e.g. 24V/3A for 5m, 24V/6A for 10m at 15W/m).

2. Controller — connect power supply output (V+ / V-) to the RGB controller power input.

3. Strip — connect controller RGB output to the strip pads: black to +DC24V, red to R, green to G, blue to B. Solder or use quick connectors.

4. Cutting — cut only at the marked 50mm scissors line; each cut segment is a complete working unit.

5. Mounting — peel the 3M backing tape and press into aluminum channel or directly on a clean dry surface.

Power calculation: strip length (m) × 15W/m = total wattage. Add 20% headroom when selecting the driver. Example: 5m × 15W = 75W → use a 90-100W DC24V driver.

Distance: for runs longer than 5m from the driver, use thicker gauge wire (18AWG or lower) and wire in parallel to avoid voltage drop and brightness falloff.

6. Technical FAQ — 24 Questions Answered By Our Engineers

Q1. What voltage does this strip need?

A1. It is a DC24V constant-voltage strip. Never connect to AC mains directly. Always use a matching DC24V driver with sufficient wattage.

Q2. How many LEDs per meter?

A2. 480 LEDs/m — ultra-high density COB chips that produce a completely dot-free seamless light line.

Q3. How much power does it draw?

A3. 15W per meter at full brightness white-free RGB mix. A 5m reel needs roughly 75W of driver capacity (add 20% margin).

Q4. What is the PCB width?

A4. 10mm wide white PCB — a balanced profile that fits most aluminum channels (10mm slot or wider) and standard diffusers.

Q5. Where can I cut the strip?

A5. Cut only at the marked 50mm intervals (scissors icon on the PCB). Each 50mm unit is a complete cuttable segment with its own solder pads.

Q6. What is the IP rating?

A6. Options from IP20 (bare, indoor dry locations) to IP44 (splash), IP65 (silicone-coated) and IP68 (fully potted, submersible). Confirm the option when ordering.

Q7. Does this product have a CRI rating?

A7. No. This decorative RGB product does not publish a CRI index. If you need CRI-graded white light for task or retail applications, choose our CCT / tunable-white COB series.

Q8. Can I dim this strip?

A8. Yes — 0-100% smooth dimming is supported by most RGB controllers, including RF remote, WiFi (Tuya/Home Assistant), 0-10V and DMX via a decoder.

Q9. Which controller do I need?

A9. Any standard RGB (3-channel) controller rated for DC24V and the total current. For smart home integration choose a WiFi RGB controller.

Q10. Can I run multiple reels together?

A10. Yes, up to the controller/driver current limit. Use parallel wiring from the driver for runs over 5m to avoid voltage drop.

Q11. How bright is it compared to SMD strips?

A11. At 15W/m and 480 LEDs/m the luminous effect is rich and continuous. Because the light is diffused by the COB phosphor coating, the perceived surface glow is smoother and more premium than SMD strips of similar wattage.

Q12. Is it really dot-free?

A12. Yes — 100% dot-free. The 3-in-1 chips sit under a continuous phosphor layer, so no individual light point is visible from any angle.

Q13. Can I solder wires to it?

A13. Yes, the copper pads at each cut point accept standard soldering. Quick-connect clips (JST style) are also available for tool-free installation.

Q14. What wire colors map to what channels?

A14. Convention: black = +DC24V, red = R, green = G, blue = B. Always double check polarity before powering on.

Q15. Does it come with adhesive tape?

A15. Yes — high-tack 3M backing tape is pre-applied. Clean and dry the mounting surface (alcohol wipe recommended) before pressing.

Q16. What is the operating temperature range?

A16. -20°C to +45°C ambient. Keep the strip away from heat sources and ensure the aluminum channel provides passive cooling for long runs.

Q17. How long does it last?

A17. Rated >50,000 hours with correct driver and proper heat management.

Q18. Can I use it outdoors?

A18. Only the IP65 / IP68 versions. Bare IP20 strips are for indoor dry locations only.

Q19. What is the beam angle?

A19. 180° — the light spreads evenly from the flat surface, ideal for coves, channels and direct glow installations.

Q20. Does the color look the same along the whole reel?

A20. Yes — binned chips and stable DC24V design ensure consistent color and brightness across the full 5m reel.

Q21. What length options do you offer?

A21. Standard 5m per reel; custom lengths available for bulk orders. We also support OEM cutting and connector pre-wiring.

Q22. Can I install it behind a TV?

A22. Absolutely — 480 LEDs/m gives a flawless halo effect with zero dots. Use the IP20 version in a channel for the cleanest look.

Q23. Is it compatible with DMX512?

A23. Yes, via a standard DMX512-to-RGB decoder (DC24V). Ideal for stage, bar and architectural projects requiring zone control.

Q24. What is your MOQ and lead time?

A24. MOQ is 1 reel for samples and 50 reels for bulk. Lead time: 3-5 days for stock colors, 7-15 days for custom lengths or waterproof versions. Contact us for a quote — our engineers reply within 24 hours.
