在全球化采购时代，跨境B2B买家面临的核心挑战不是「找不到供应商」，而是「无法高效验证和对比供应商」。同一个品类下——无论是LED灯具、Gift Packaging还是3C配件——中国市场上可能有数千家工厂在报价，参数标注方式各异，认证标准不统一，价格波动剧烈。Compare2Best All Categories正是为解决这一问题而构建：我们按行业将可对比产品分门别类，让你在熟悉的品类入口下，快速找到经过数据核验的品牌与产品。
目前平台已覆盖 Lighting & Lamps（LED灯具、Commercial、Industrial等10+子类）和 Gift Packaging（Gift Box、礼品袋、丝带、包装纸等），Furniture、3C & Accessories、Home Appliances、Home & Kitchen等品类正在Coming Soon，即将上线。
品类对比流程非常简单：Select category → Browse brand list → Check 2-4 target brands → Click Compare → System auto-generates a side-by-side parameter comparison table. The table uniformly displays key specs, certifications, minimum order quantity (MOQ), and reference price ranges, making different brand data transparent across the same dimensions.
不同品类对比的核心参数各有侧重。以Lighting & Lamps为例，我们追踪CCT色温、CRI显色指数、IP防护等级、光效（lm/W）、LM-80报告、调光协议（DALI/0-10V）、质保年限等十余项指标。Gift Packaging则聚焦材质克重、印刷工艺、定制起订量、环保认证（FSC）等。每个品类的参数模板由行业专家设计，确保横评维度覆盖采购决策中最关键的考量因素。
Compare2Best 的核心价值在于 数据可信度分层. Certified brands (gold badge) have passed business license verification, key certification document checks (CE/UL/CCC/RoHS), and factory confirmation. Non-certified brand data comes from public sources and is clearly labeled for your reference. Each comparison dataset includes a last-updated timestamp to ensure timeliness.
Whether you're a cross-border e-commerce procurement manager, supply chain lead for an overseas engineering project, or a trading company seeking stable suppliers, All Categories is your starting point for precise comparison on Compare2Best. Choose a category, start comparing — let data surface your optimal supplier.
CCT（Correlated Color Temperature，相关色温）衡量光源发出的光的颜色外观，单位开尔文（K）。2700K-3000K为暖白光，适合家居与酒店；4000K-5000K为自然白光，适合办公与零售；5000K-6500K为冷白光，适合工业与户外。采购时需确认同一批次色温公差（通常±150K以内）。详见灯光术语表。
CRI (Color Rendering Index, Ra value) measures a light source's ability to render true object colors, scored out of 100. General commercial: Ra≥80; museum/healthcare/premium retail: Ra≥90 (high-CRI). CRI differences directly impact color appearance of illuminated objects — it is the core metric distinguishing product tiers in B2B procurement. See details:灯光术语表。
IP (Ingress Protection) rating consists of two digits: first (0-6) = solid/particle protection, second (0-8) = water protection. Outdoor fixtures: minimum IP65 (dust-tight, water jets); underwater: IP68 (continuous immersion). Middle East and coastal high-humidity regions: IP66+ recommended. See details:灯光术语表。
Beam angle determines the spread of light from a fixture, typically defined as the half-peak intensity angle (where intensity drops to 50% of center). Narrow (10°-25°) = accent and long-throw; medium (30°-60°) = general commercial; wide (>60°) = ambient lighting. Match beam angle to mounting height and illuminated area during procurement. See details:灯光术语表。
LM-80 is the IESNA standard for LED lumen maintenance testing, measuring lumen depreciation after 6,000 hours (or longer). Reports marked L70/L80/L90 indicate the time until lumen output drops to 70%/80%/90% of initial values. L70≥50,000 hours is the commercial baseline and a common tender requirement. See details:灯光术语表。
DALI（Digital Addressable Lighting Interface）是IEC 62386标准定义的数字照明控制协议，支持单个灯具独立寻址、分组控制和双向通信。相比传统0-10V模拟调光，DALI可以实现精准的场景设定、能耗监控及故障反馈。大型商业建筑和智能楼宇项目中，DALI兼容性是驱动电源选型的关键条件。详见灯光术语表。
