Double Sides Lighting LED Neon Flex Rope Light 12V Input LED Neon Rope Light waterproof

Product Positioning

1. 108pcs High-Brightness SMD2835 LED Source (108 LEDs/m)

• 108 LEDs/m high density: Distributes light sources evenly along the entire strip length, providing sufficient light source density for both sides of the light-emitting surface — eliminating visible LED hotspots even at close inspection, critical for double-sided architectural outlines where viewers may be close to one face.
• SMD2835 efficiency: 105–120 lm/W typical efficacy, 8W/m @ 12V DC (8W/m @ 24V DC, 10W/m @ 110V/220V AC) — up to 90% energy savings vs. 25–30W/m traditional 3kV–15kV glass neon.
• Color consistency: SDCM <3 (Standard Deviation of Color Matching) tolerance ensures zero perceptible color shift between batches, even for 50+ location rollouts ordered years apart. Ra >80 (white variants) for comfortable commercial glow.
• Voltage variants & LED density: 12V and 24V DC versions use 108 LEDs/m; 110V and 220V AC versions use 120 LEDs/m — the DC variants trade a marginal LED count for finer cutting resolution and safer low-voltage operation.
• Low operating temperature: <30°C surface temperature even after 24hrs continuous operation, safe for indoor public spaces and near outdoor flammable materials.

2. LED & Components Double Protected — No “Unit Failure” Cascade

• Circuit-level redundancy: The flex incorporates a double-circuit backup system — either in a parallel-grouped circuit design (where 3 LEDs per group at 12V, 6 LEDs per group at 24V act as independent branches) or a dual-circuit backup system, if a single LED degrades/dies, the rest of its branch stays lit, and failure does not cascade to the rest of the run. The underlying principle is proven: when one LED chip in a parallel dual-chip configuration fails open, the other continues conducting, keeping the bulb lit at consistent luminous power and preserving the brightness/color of the entire flex body. This “double protection” ensures the strip continues illuminating even if one circuit path is compromised — a critical reliability advantage for high-profile architectural installs.
• Component-level sealing: Every SMD solder joint is secondary-coated with clear silicone before PVC jacketing, preventing moisture/oxidation from reaching circuits even if the outer jacket is nicked during install. Injection-molded nylon end caps + potted sealant at strip terminations add a second layer of isolation.
• Pure copper FPC: Minimizes voltage drop on long runs — 12V/24V DC versions support up to 20m single-feed runs without “bright head / dim tail” effect.

3. First-Class Eco-Friendly UV-Resistant PVC Material

• Eco-friendly & non-toxic: RoHS/REACH certified, zero lead, mercury, or phthalates — safe for indoor public spaces (schools, food retail, healthcare) and outdoor use.
• UV-resistant stabilization: Imported UV stabilizer additive resists photodegradation and antioxidant degradation, ensuring the jacket does not discolor or become brittle after prolonged sun exposure — maintains optical clarity for even light transmission from both faces over the product’s 50,000-hour rated lifespan.
• Flame-retardant: Meets UL94-V2 standard for indoor fire safety.
• Milky-white diffuser jacket: The eco PVC is extruded into a milky-white diffuser profile that scatters direct LED light evenly — critical for the “no LED dot” performance on both emitting faces.
• Upgrade note: For full outdoor exposure (direct rain, coastal salt spray, >2 years UV), we recommend our silicone co-extruded series — this PVC line is optimized for cost-conscious projects with covered or semi-outdoor installation.

4. Double Lighting — High Brightness, Uniform Glow, Zero Dots/Dark Spots

• Dual-face emission: SMD2835 array is centered within the PVC jacket, emitting uniformly from both lateral faces. When the strip is mounted on a 2D surface (e.g., building edge, bridge rail), both the viewer-facing side AND the opposite side glow — eliminating “dark face” shadowing.
• High brightness + uniformity: 108 LEDs/m high density + milky-white PVC diffuser jacket scatters direct LED light into a continuous, linear glow on both faces — no visible LED dots even close-up, no dark spots between cut points or LED clusters.
• Even color mixing: Single-color variants deliver consistent chromatic uniformity across the entire run; the high LED density ensures smooth color transitions with no “banding” or hotspotting.
• 160° light distribution: The PVC diffuser delivers wide-angle uniform glow, suitable for 1–3m effective light throw distance for architectural outlining.
• Result: A true “neon tube” aesthetic — continuous, dot-free glow visible from any angle around the installation, perfect for architectural features viewed from multiple vantage points.

5. Easy to Install, Cuttable & Reconnectable

• Marked cut points​ (varies by voltage variant):
  • 12V DC: every 2.77cm / 3 LEDs per cut unit — finest cutting resolution, ideal for precise architectural detailing
  • 24V DC: every 15cm / 6 LEDs per cut unit
  • 110V AC: every 50cm / 60 LEDs per cut unit
  • 220V AC: every 100cm / 120 LEDs per cut unit
  • Cut only at these marked black lines to avoid damaging parallel circuits.
• Horizontal bending: Minimum bend diameter 8cm, bends horizontally to follow arched windows, bridge parapet curves, and irregular sculpture outlines without kinking.
• IP65 reconnect accessories available: Matching nylon waterproof connectors + pre-measured silicone sealant kits. Cut, plug in, reseal with provided glue, and retain full IP65 rating.
• Mounting flexibility:
  • Indoor: Compatible with 3M VHB double-sided tape application on FPCB backside for peel-and-stick install
  • Outdoor: Compatible with standard aluminum extrusion channels (sold separately) for added protection and heatsinking
• Wide operating temperature: -30°C to +45°C ambient — performs reliably in both northern winter and hot-climate summer installations.
• Max run length: 12V/24V DC: 20m per single power feed; 110V/220V AC: up to 100m per single power feed.

6. Protection Rating IP65 (Critical Install Requirement)

• IP65 certification: Dust-tight, resistant to low-pressure water jets (light rain, sprinkler overspray, outdoor humidity) — suitable for covered patios, building outlines, bridge parapets, sign boxes, and walkway edges.
• Not submersible​ — for immersion use, upgrade to our IP68 silicone series.
• Mandatory install step: All cut points, connector joints, and strip terminations MUST be sealed with the provided silicone glue during installation​ to maintain IP65 rating. This step is critical: unsealed joints are the #1 cause of field failure in “waterproof” neon flex. Our accessory kits include step-by-step sealing instructions to avoid this common pitfall.

Typical Applications (Double-Sided SMD2835 PVC Series)

• Indoor & outdoor architectural outline decorations: Building contours, cornice edges, window frame outlines, lobby feature walls
• Walkway & park guiding-line lighting + landscaping: Municipal park trail guidance, pedestrian pathway edges, garden landscape accents, resort walkway outlines
• Bridge, sculpture, building contour & board fringe illumination: Bridge parapet dual-face outlines, public art sculpture edge lighting (3D forms where both faces are visible), high-rise building rooflines, billboard/ad board border fringes

Vasten Quality Backing (Same Bar Across All Tiers)

• 100% FPCB/LED incoming batch inspection
• 48–72hr mandatory burn-in per production batch to catch early-life failures
• 2-year pro-rata warranty

⚠️ Engineer’s note on model selection: Choose 12V DC for short runs (<5m) and automotive/RV applications where finest cutting resolution (2.77cm) is needed; 24V DC for mid-range runs (5–20m) with minimal voltage drop; 110V AC (North America) or 220V AC (EU/Asia) for long single-feed runs (30–100m) on large-scale building/bridge outlines. Confirm cut length intervals and max run length per your selected voltage variant before ordering.
