off-grid home lighting from solar panel and 12v battery? Answered
I ran 3 parallel circuits DC all hooked to a circuit going to battery. each circuit had a 5w and a 3w high-powered LED and a 2w resistor.
I spaced the led's about 4 feet apart in each circuit and the lighting was spectacular. lit up 300+ sq. ft. with 6 led's. then one of the 5w
led's flickered, turned blue, and dimmed permanently. I don't know what I did wrong. I thought led's would only use power available.
the guy at superbright led wanted to sell me a $20 direct current driver for each light, which would make the cost 50 times higher.
he said my math was ok and it should work. each light had it's own heat sink. any help greatfully appreciated
