Both Panasonic and Sanyo have put their thinking caps together, working in harmony to roll out the EVERLEDS lithium-ion solar street light. You just gotta love the name as well as the ring to it – EVERLEDS sounds as though it can last virtually forever, don’t you think so? Featuring Sanyo’s HIT solar cells that boast the highest-class conversion efficiency in the world, it can provide enough juice for the high efficiency LED lights to keep on going for around 15 hours during the night without missing a beat – making it perfect for places that have long winters and short daytimes.
