I'm looking for a reliable supplier for solar street lighting systems that come with poles designed for dual arms. The key features I need include efficient solar panels, durable construction to withstand various weather conditions, and an integrated lithium battery for optimal energy storage and longevity. Additionally, it's important that these lights provide effective illumination for public spaces, ensuring safety and visibility. Please include details about the specs, warranty, and available customization options for both the solar panels and the poles. I'm eager to understand the pricing structure and lead times for bulk orders as well. Looking forward to your prompt response!
