ENER-J LumiFlex Ultra FCOB Neon Strip — Warm White, 50M, 240 LEDs/m, 1000 lm/m, Direct AC, 2.5cm Cut, IP65

There is a ceiling to what standard SMD LED strips can achieve — and it’s visible in the output. No matter how many LEDs per metre, individual SMD chips produce a subtle but consistent dot pattern that even a good diffuser can only partially conceal. FCOB technology eliminates this entirely. The ENER-J LumiFlex Ultra WW-N110 uses FCOB LED strip technology for architectural cove lighting and premium neon installations — Flip Chip on Board construction with 240 LEDs per metre producing an absolutely continuous, perfectly uniform warm white glow through milky silicone. No dots. No variation. No compromise. The most advanced LED strip in the LumiFlex range, and the specification for projects where the quality of the light is as important as anything else.

What Makes FCOB Technology Genuinely Different

• FCOB vs SMD — why the architecture matters: Standard SMD LED strips (including every other product in the LumiFlex range) use LED chips mounted on a substrate and connected via wire bonds. FCOB (Flip Chip on Board) eliminates both the substrate and the wire bonds — chips are flipped and bonded directly onto the copper PCB. The result is a fundamentally more compact, more thermally efficient, and more optically uniform light source. At 240 LEDs per metre packed this closely together, individual light points are physically indistinguishable — the output is continuous, uniform, and perfectly consistent from end to end in a way that no SMD strip at any LED density can fully replicate.
• 240 LEDs per metre — double the density of every other series in the range: The Pro, Slim, and Neo series all use 120 LEDs per metre. The LumiFlex Ultra doubles that to 240 — and combined with FCOB’s inherently compact chip format, the result is an LED density that makes individual dots physically impossible to perceive even at the closest viewing distance. For architectural cove lighting, hotel corridor details, and precision interior installations where the strip is seen at close range, this matters enormously.
• 1000 lumens per metre at 110 lm/W — premium output and efficiency: At 1000 lm/m and ~110 lm/W efficacy, the LumiFlex Ultra delivers maximum lumen output with excellent energy efficiency — matching the Pro series output (1000 lm/m) while running at higher efficacy. FCOB’s better thermal management means the LEDs run cooler and maintain output more consistently over time than equivalent-density SMD strips.
• Milky silicone diffuser — smooth neon-like glow without glare: The 10mm milky silicone jacket diffuses the FCOB output into a smooth, even, neon-effect glow — no glare, no harsh hotspots, just the premium continuous light appearance that architectural and hospitality specifications require. The combination of FCOB’s inherent uniformity and the milky silicone diffusion creates the closest possible replication of a premium neon tube effect in an LED strip format.
• Direct 220–240V AC — no external driver required: Despite its advanced technology, the LumiFlex Ultra connects directly to mains power with no external driver needed — the same installation simplicity as the Pro and Slim series. For large-scale architectural installations where concealing driver boxes is a genuine challenge, this significantly reduces installation complexity and eliminates a common long-term failure point.
• Cut every 2.5cm — architectural precision at any length: The 2.5cm cutting interval — shared with the Neo 12V series — gives professional installers the precision to fit the LumiFlex Ultra exactly to any architectural cove, recess, or profile. For hotel corridors with specific cove lengths, custom furniture with precise channel dimensions, or complex facade profiles where a 1-metre cutting interval would create waste and compromise, the 2.5cm interval is the standard that professional work demands.
• Lock-N-Lock connector system — faster installation, secure connection: The proprietary Lock-N-Lock connector provides a secure, reliable mains connection without loose terminal blocks or soldering. Compatible accessories include the ACC1133 (4A Lock-N-Lock connector with India 2-pin plug for power input), ACC1134 (strip-to-strip connector), ACC1135 (silicone end cap), and ACC1136 (strip-to-strip connector with 10cm cable) — all available separately to support any installation configuration.
• Pure copper PCB for sustained premium performance: Pure copper PCB construction — not copper-clad aluminium — provides the thermal conductivity needed to keep 240 FCOB chips per metre running at optimal temperature across continuous long-duration operation. Better heat dissipation directly translates to maintained lumen output and consistent colour temperature over the lifespan of a permanent architectural installation.
• Operating range -20°C to +50°C — suitable for Indian conditions: An explicitly tested and rated operating temperature range that covers India’s most extreme outdoor and indoor temperature conditions — from cold northern winters to peak summer outdoor facades in Rajasthan. Most LED strips don’t specify this range; the LumiFlex Ultra does.
• IP65 for outdoor facade and exposed architectural use: Fully sealed against dust and water — suitable for building facades, outdoor architectural features, covered outdoor hospitality spaces, and any indoor or outdoor installation where the quality of the light output justifies the premium specification and durability to match is required.
• 50-metre professional roll for large architectural projects: A full 50-metre roll with 2.5cm precision gives professional installers enough strip for large hotel corridor installations, extensive facade work, and complex multi-run interior projects — all from a single consistently produced roll with matched colour temperature and output throughout.
