Ok just got the SUNFORCE Triple Head Solar Motion Activated Light at Costco. They have different versions on Amazon: http://amzn.to/2EMFY8N The Solar panel generates about 6.3+ volts to 7.5 volts to charge the 3 AA Nimh in the case. I charged the 3 AA batteries with solar (left it in the sun for 3 days and with a smart AA battery charger. The light battery life lasts for about 32 minutes before it goes dim. So if you plan to leave it on for a longer time than 30 minutes you should consider something else.
