タイトルまたは説明

• Solar panel: strategic partner with long-term relationships, panel conversion efficiency can be up to *7%, **-year life and *-year guarantee
• Battery: can supply both Lead-acid and gel type and battery supplier is selected by us after long-term test and practice, reliable, over charge and over discharge protection, 8 to **-year life and *-year guarantee

• *-piece LED not working, won't impact other LEDs
• Controller: **0, *0 and *0% power
• Functions: can choose 0 to *-hour in different working power period for example: 3 + 3 + *-hour mode, means *-hour **0% power working + *-hour *0% power working + *-hour *0% power working
• Can also adjust it **0% + *0%, *-working period or all night only full power working
• Constant-current power supply and control system integrated, usually put controller in under part of pole, because LEDs itself has very long life, only need ride bike to exchange controller if light doesn't work, this decreases maintenance fee as needn't use crane to take the light down to do repair any
