guys im doing some project with solar panel,led and rechargable battery
situation-i want make a light box using 40 white led with solar panel and rechargeable battery.at daylight the solar panel will charge the battery and by night it will on the led.
all 40 led is in series with 10 of then per row ( mean got 4 row x10 led each) inside 2feet x 2feet box.
im trying to use 12v rechargeable battery to light up 40 led at night.
my problem is i dont know if 12v battery can light 40 led for estimation 12hours.do i need higher rechargeable battery voltage or something??? or do i need to reduce LED amount by using super bright white LED because i read that super bright LED using higher voltage...
please give me some idea...i know its simple project but for newbie like me im totally out of idea..
