After watching the technology of lighting evolve for years the system I waited for was finally developed. The efficiency and convenience of a solar recharging LED camp light is here and it'Äôs great. The long life and adjustable brightness is perfect for the tent (bright enough to read for hours) as well as countless other uses. Great to have and a great gift too.I am very pleased with my LUCI and I think the Earth will appreciate it'Äôs sustainability.
