This is intended to replace open wick kerosene lamps in places that don't have electric service. For that, it works very well. Solar with batteries would also work, but would require annual battery replacement. This will work for years without any intervention.
By first world public utility standards, the light is extremely dim. Compared with kerosene lamps, it's much brighter. Unlike kerosene, there's no ongoing expense, just the labor of raising the weight every 20 minutes. Poverty means you can't trade your labor for much value. This offers the world's poorest people a little light for a little lifting. That's a good deal. (BTW, I don't think they're the equivalent of $80 each in the third world.)
So why would a first world guy like me buy any? First, because these folks are doing a good thing, and doing it the right way. They have a good technical idea, and they're making a proper sustainable private business of it, not a charity, assembling in Kenya for the market there. Second, though L.A. has regular DWP power at the moment, a day will come when a major earthquake will take that away. Unlike battery solar systems, these can be stored for decades and should work when the need arises. Third, it's a novelty and a very well done job of engineering.
To use the device, you raise up the weighted nylon sack by pulling on one side of the orange cord (like a curtain shade adjuster). There is only one orange colored cord among a bunch of black cords, so i'ts not hard to find, and it's also not difficult to pull the 25lb sack up in this manner. As the sack slowly descends via gravity, it feeds the LED energy. This set also provides two separate mini-lanterns and 2 long cords, which you can hook to the "head" and then to each other, to make a string of 2 lantern lights (when the 2 lanterns are in use, the main head lamp does not turn on). This allows you to split the lighting, and to have the option to place lights closer to where you need them. Each of the 2 lanterns can be adjusted by twisting, for three separate lighting levels, so if you plug them in and they don't turn on, try twisting to turn them on. The two lanterns together at their highest levels are about the same brightness as the main headlamp.
Overall, I found this device to be a novelty and pretty cool as a concept, but a bit cumbersome in use- it's a testament to the good design that the cords on this device don't get tangled up, considering how many there are, and how closely they are placed together. On the other hand, you still just have a ton of cords, and it looks very messy and takes up a lot of space...and there's no way i'm taking this hiking. It'd be great for car camping though. I have solar lanterns that weight a few oz and run for 10 hours with 10 times the light as this GravityLIght. But, they still need sunlight and hours to charge. This GravityLight works instantly, and can be a lifesaver if you truly are out of options- no batteries, no wind-ups, no solar, no candles, no fire... this also overcomes the obvious and significant disadvantage of using up a non-renewable energy source, and then being SOL. So, I'd say this is good to have for your tool kit of available lighting options, either at a campsite, for emergency planning, or just as a conversation piece showcasing the clever engineering.
