Selecting the ideal decoration lamp requires matching the lighting technology with the intended environment. For hospitality and restaurants, prioritize lamps with a High Color Rendering Index (CRI >90) to ensure food and decor appear vibrant. For outdoor landscapes or patios, ensure the lamps have an IP65 or higher waterproof rating to withstand weather elements. If sourcing for retail or home decor, focus on CRI and CCT (Correlated Color Temperature) flexibility, such as 3000K (Warm White) for cozy atmospheres or 5000K (Daylight) for modern, crisp aesthetics.
