I'm looking for a reliable supplier for high-quality 500W LED lights suitable for high mast applications. Please share details on the specifications, including brightness, energy efficiency, and any certifications these lights might have. Additionally, I'd appreciate information on pricing, minimum order quantities, lead times, and warranty options. If you have any available catalog or product samples, that would be helpful as well. Looking forward to your quick response so we can move forward!
