I'm interested in sourcing 60W street lights that provide 7000-8000lm with at least 120lm/W efficiency. They should be suitable for mounting on 8-meter poles and require separate units for lamps, batteries, and solar panels. Additionally, the lights should be designed to operate for 12 hours daily. Could you provide details on available products that meet these specifications, including pricing and lead times? Looking forward to your response!
