Feature:
Over-charge protection.
Over-discharge protection.
Constant current drive.
Equipped with bright white light and color slow flashing light.
Using photoresist-free light control technology.
Charging during the day and automatic power on at night.
Use of single-cell lithium batteries/lithium iron phosphate.
Applicable occasions: lawn light/wall light/post light/string light/Christmas light/daylight/fluorescent light/night light, etc.
The board features high driving efficiency, long discharging time, small area requirement for solar panel, charging protection, discharging protection, constant current driving, etc.
There are two light colors: white light and color slow flash. The white light is very bright, and the color slow flash has a strong atmosphere!
