I'm looking to explore options for solar lights for an upcoming project. Specifically, I'm interested in different styles, features, and capabilities that could fit both residential and commercial applications. Could you provide details on your offerings, including pricing, bulk order discounts, and any certifications? Additionally, I'd love to know about the various wattages available and their respective brightness levels. Information on battery life and charging times would also be helpful. Please share any catalog or datasheet that outlines your solar light products and their specifications. Looking forward to your response!
