The world’s first illuminated pillow- and while not specifically marketed to backpackers, I think it is going to work as a sleeping pillow.
First of all, it is just 3 ounces, complete with solar charger. Nothing could be simpler than to operate this unique product. You place it in the sun, and it charges, indicated by a red LED. There is just one button, which has off, low, and high settings. How about a waterproof lantern that can even float when inflated? The unit fully charges in 5 hours of sunlight, and provides 4 hours of light on the High setting and 6 hours of light on Low. The battery is reported to last for 800 charge cycles, and most astoundingly, holds a full charge for 6 months!
The project itself funded with many $25 donations, and for that $$ you received your own light and also paid for a light to be shipped to a third world country. Online sales are coming soon–> luminAID’s mailing list will keep you updated.
I plan to write a report on how this light fared on my 2 night camping trip in Camden Hills State Park this upcoming weekend.
