Hey Everyone, I am about to embark on a new project and would like some guidance if possible, please forgive the post if its missing information as electronics and circuits is all new to me. I need some assistance with a project and will post the details as follows. I am trying to create a rechargeable led strip light that comes on at dusk for the outside deck. I want to make itself contained so I dont have to run power leads Now this is where I need some help, trying to work out the most cost effective method that produces the longest light up time. So this is what I am thinking: 1x 30cm - 50 cm strip 5050 12v LEDS (approx: 30 LEDS for 50 cm and 20 LEDS for 30cm) Power: YUASA - Y1.2-12 - BATTERY, LEAD ACID, 12V, 1.2AH I think this would power these for around 1200 hours??? I am also going to integrate a lamp adapter circuit that switches on when its dark. I am going to up cycle from this http://www.ebay.com.au/itm/281257881002?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 It seems cheaper than making my own circuit. I would just like to know if I am on the right track.
