LED based street lighting with automatic intensity control using solar PV

simple automatic solar night light circuit from water

sep 23, 2019 he choose to use 2 x aa nickel metal hydride battery total voltage is 2.4v at 500mah. it need to used current about 50ma 80ma. thus he cannot use a white led because it use 3.3 3.6v. as this solar led garden lights circuit. we use the relay to control current because it s easy. but relay works by coil which use high current about 80ma.
