The festival lighting industry is no longer in the era of "one product lasts ten years." Shopping malls, tourist attractions, and brand events want more than just "lights that work." They want "this year's look." Tastes change. Needs change. Application scenarios change. Can one product last five years? Sure. But your competitors are already using new designs to attract visitors. LEJIN insists on regularly launching new designs — not just for the sake of "newness," but to "keep up with our customers."   Why Regular New Products? Motif lights are the visual focal point of commercial spaces and holiday scenes — Christmas displays in mall atriums, festive installations in plazas, branded symbols for events. But motif lights have one defining characteristic: they exist to create freshness. The same Santa Claus display, year after year — customers glance and walk away. The same pumpkin light, season after season — no one stops to take photos. The styles, sizes, themes, and lighting effects of motif lights all need continuous renewal to keep capturing consumer attention.     How We Do It New products don't appear out of nowhere. They're backed by a complete R&D system. LEJIN has an in-house design team that handles everything from concept to drawing — no outsourcing, faster communication, and more efficient revisions. Our creative direction follows industry trends and customer feedback, while also tracking shifts in overseas market preferences. We plan new products around seasonal peaks like Christmas and Halloween — staying ahead of each holiday cycle. Once designs are finalized, our in-house mold workshop and mature production lines move quickly from sampling to mass production. We can imagine it. And we can make it fast.     What Value Do New Products Bring to Clients? Keep it fresh every year: Commercial spaces need constant renewal. Regular new products give clients fresh content year after year — no more using the same lights every season. Stay ahead of the curve: What we launch reflects where the market is heading. Clients who choose our new products are moving with the trends. Save time and effort: We handle design and development. Clients simply choose and order — no need to find designers or handle sampling themselves. Create buzz: A standout decorative light is naturally shareable. Customers see it, take photos, post on social media — that's free exposure for their venue.     LEJIN is not just a "outdoor decorative lighting seller." We are a "partner that continuously provides fresh options for clients." Regularly launching new products isn't because we "can't sit still." It's because our clients need it. The market needs it. We don't promise one product that sells for ten years. What we promise is this: Every year, new products are brought to market — delivering more competitive lighting solutions for our clients.

    Many customers only care about whether decorative lights turn on. But what really determines their performance is whether they stay on — and for how long — under different conditions. Outdoor decorative lights face real challenges: summer heat, winter freezing, heavy rain, coastal salt spray, and long-term UV exposure. Before leaving our factory, every LEJIN decorative light product goes through five tests: High & Low Temperature Test, Rain Test, Salt Spray Test, UV Aging Test, and Pull Test.   1. High and Low Temperature Test We place light strings in a temperature chamber and operate them continuously at temperatures ranging from -40°C to 70°C to check their performance under extreme heat and cold. Summer ground temperatures can exceed 40°C — decorative light strings hang outdoors from morning to night. In northern regions, winter temperatures drop to -20°C or lower — wires become stiff, solder joints become brittle. Through this test, we ensure decorative lights work properly whether they're shipped to tropical or freezing regions — starting up reliably, maintaining stable brightness, with no material deformation or cracking. No "heat stroke," no "freeze-up."     2. Rain Test Outdoor festival lights face rainy seasons, typhoons, and humid weather. We spray products with water according to IP44 and above waterproof standards, simulating different angles and intensities of rainfall. String lights, connectors, and controllers — water intrusion anywhere can cause short circuits, electrical leakage, or complete failure of the entire festival light string. Through the rain test, we ensure festival light strings stay on during heavy rain — connectors stay dry, controllers stay safe.     3. Salt Spray Test Coastal cities, beach resorts, and harbor commercial areas have high salt content in the air. Ordinary metals rust within days. We place decorative festival lights in a salt spray chamber for hours or days to observe corrosion on metal parts, solder joints, and screws. Rusted screws mean decorative lights fall. Rusted solder joints mean decorative lights fail. Through the salt spray test, we ensure decorative light products don't rust quickly in coastal environments — installed once, they stay put, able to withstand sea breezes.     4. UV Aging Test Outdoor decorative lights are exposed to sunlight for years. Wires, housings, and lenses slowly age — yellowing, becoming brittle, even cracking. We use a UV aging chamber to simulate long-term sun exposure, accelerating the aging process to check material performance changes. Yellowing is a cosmetic issue. Cracking leads to water ingress and failure. Through the UV aging test, we ensure decorative light products remain in good condition after years of outdoor use.     5. Pull Test This is a test many customers don't think about — but it's one of the most common pain points during actual installation. Workers pull wires when hanging string lights and drag strings during setup — these actions create tension on the connections between wires, plugs, and sockets. If solder joints are weak or crimps are loose, wires can pull out, leading to poor contact or lights not working. In worse cases, it can cause short circuits, overheating, and safety hazards. We use professional pull testing equipment to apply standard-specified tension to power cords and connection points — ensuring every wire is properly soldered, securely crimped, and able to withstand pulling force.     LEJIN decorative lights must pass these tests before shipment: temperature, waterproofing, corrosion resistance, UV aging, and pull strength. Each test is not a formality. It's a real quality threshold. We don't promise "never fails." But we promise this: every batch of decorative lights that leaves our factory has gone through these tests.

    The motif lights arrive. You open the box. Wires, parts, controllers — and then what? This is the first reaction of many customers after receiving their order. Without installation guidance, they have to figure it out on their own: trial and error, rework, realizing halfway through that something is wrong, or even damaging the string lights. It wastes time, and the final effect often falls short. LEJIN's solution is simple: printed installation instructions + video tutorial. No guessing. Just follow along.   Two Formats to Cover Different Needs 1. Installation Guide (Illustrated) A printed instruction manual is included with the shipment, and a digital version can be sent in advance. It includes: parts list, installation sequence, mounting methods, wiring diagrams, important notes, and more. Perfect for quick reference while working. 2. Installation Video Tutorial (Demonstration) We provide live-action or animated walkthroughs based on customer lighting string needs — guiding them step by step. The video includes: unboxing, assembly process, mounting methods, power-on testing, and more. It breaks down language barriers — just watch the pictures and follow along.     More Than Convenience — It Reduces Risk Save time: Connecting frames have matching number codes. No need to figure it out yourself — just match the numbers. Installation time is cut by at least half. Save hassle: Avoid rework from incorrect installation. Get it right the first time — no taking things apart and starting over. Reduce risk: Poor installation can cause lights to fall, short circuits, or waterproofing failure. We tell customers how to avoid these issues before they happen.     From Factory to Customer — Peace of Mind at Every Step Before shipping: We send the digital installation guide in advance, so customers can prepare tools and personnel ahead of time. At shipping: The printed installation festival lighting guide is packed with the shipment — visible as soon as the box is opened. After shipping: Video tutorials are available anytime on YouTube.
