The simple notion of using a slow-moving, falling weight to power things has been around for centuries. Think big clocks in 16th century cathedrals.
So when I saw the principle applied to an LED lamp, my first thoughts were about lighting for either off grid emergencies or off grid emergencies or lifestyles.
Using 26 pounds hung six feet above ground, the GravityLight provides 20 minutes of light. Over and over and over again. In the words of the design team:
Once GravityLight is installed and a 12kg weight – a bag of rocks or sand – attached, it’s ready to go, anytime.
The weight is lifted by pulling down on a bead cord. On release, the weight falls very slowly, transforming potential energy into kinetic energy as it powers a drive sprocket and polymer gear train.
This generates just under a tenth of a watt, to power an onboard LED and ancillary devices.
Once the weighted bag reaches the floor, which depends on how high it was installed, it is simply lifted to repeat the process.
We are so dependent on electricity for light, comfort, cooking, and sanitation that any power outage becomes a major headache for the unprepared.
And it doesn’t have to be an EMP, or a natural or man-made disaster: the U.S power grid is frail enough to “fall down” on its own.
By definition, the prepper lifestyle demands preparedness.
Compare your prep level to the Survivalist Prepper as he inventories his “lights out” kit and power outage supplies. [You can watch his video on the Next Page of this post.]
An annual exercise, he checks supply levels and expiration dates. Below is his actual inventory list:
The Lights Out Kit
What it is…
It’s for stuff that you don’t want touched … I like to have a stash set up that I know for a fact that I have the supplies that I think I have.
It’s for stuff you won’t use regularly … I have supplies around the house that I hope will be there when we need them, and I have supplies stored in my lights out kit that I know will be there when I need them.
It’s an easy go to for family. … if I am gone I know that the family can just go grab the lights out kit and have everything they need.
Light Out Kit Supply Ideas

Emergency Power Kit Maintenance & Precautions
Rotate and check supplies yearly. Twice a year is even better …
Some supplies can’t handle extreme temperatures. If you store this (or any supplies) in the garage or shed you need to make sure items like batteries and food are not stored in them … batteries need to be stored at a temperature between 60 and 85 degrees to get maximum shelf life.
Do not store liquids or fuels in the kit. If you have oil lamps or supplies that use other fuels you don’t want to store them with your other supplies …

Too Much is Never Enough
This seems like a lot of supplies right? Well, if you need to go an extended period of time without power your lights out kit is going to seem like it’s not enough.
