I am very limited in my electronic ability, and need help with this idea. I want to power a 700ma led light with a 12 volt battery. I have a nice solar panel to charge the battery during the day. My question is can I use a relay in conjunction with a photo cell that is in the normally closed position using power during the day to hold the relay open (plenty of solar power) then in the dark it closes and powers only the led light. I hope I make sense.
