When sourcing main door lights, the most critical technical factor is the IP Rating (Ingress Protection). For outdoor entrance lighting, a minimum of IP44 is required to protect against splashing water, while IP65 is recommended for areas exposed to heavy rain. Additionally, prioritize die-cast aluminum housings with anti-corrosion powder coating to ensure longevity against oxidation. For LED components, ensure a Luminous Efficacy of at least 100 lm/W and a Color Rendering Index (CRI) of Ra>80 to provide clear, natural illumination for security and aesthetics.
