博茨瓦纳采购需求：太阳能路灯

We are looking for high-quality lighting solutions that meet the following specifications. The lamp should feature an aluminum alloy construction with 80 pieces of bridge lux chip LEDs, providing a luminous flux between 13000 and 14000 lumens. The color temperature should range from 3000K to 6000K, with a light control voltage of 5V. Importantly, the lamp needs a lifespan of 50000 hours, ensuring 2-3 days of lighting during rainy conditions when fully charged. Additionally, we require a lithium battery with an 880Wh capacity and a charge cycle of 2000 times. For the solar panel, it should be a 180W/18V monocrystalline silicon model, boasting a solar efficiency of 19-20%. Each component should be individually maintainable to ensure optimal long-term performance. Please provide your best pricing and lead time for this inquiry.
