Working Process
Please install the BS-ST series waterproof solar flood light in a sufficient sunny place for fully charged, it will stop working after a long lack of sunlight irradiation. Placing the light in a sunny, open location and consistent exposure to sunlight prevents the battery from experiencing prolonged periods of discharge, which can extend its lifespan and overall functionality.

Make The Best Use of The BS-ST Series
1.DO NOT install in eaves or building shelter
2.DO NOT install under trees or in shade
3. Install in a sunny, open place without shelter

Great Efficient Solar Panel
BS-ST series waterproof solar flood light instructs the high-end solar panel, with high-efficiency charging rate > 23%, maximizing electricity production. BOSUN® dedicated to developing long life-span solar light to translate to reduced solar powered street lights cost over time. Its key advantage lies in its outstanding efficiency, which allows it to seize and convert a higher percentage of sunlight into electricity compared to generic solar panels.

High-End Philips LED Chips
BOSUN® Lighting is the best solar street light brand, making use of international standard LED chips, and assurance of product quality.
