Fill the bag with 28 pounds of something (It comes with paper bags to fill it with sand or rocks, but I used cans of nails and bolts that were in my shed, where I am using the lamp. I do not have electricity in my shed, so I was very glad to have the ability to have light. The light is not very bright, but it does come on a cord that can be moved around and hung where you need it, The cord attaches into the lamp itself. There are actually two cords and two lights but I cannot figure out how to attach them both at the same time so I am guessing that one is supposed to be a replacement. It would be nice if you could use them both at the same time because then you could have two light locations. It takes a fair amount of space for this device because the bag eventually falls all the way to the floor. It is easy to pull the cords, and once pulled they give about 20 minutes of light. Then you just pull them again. Very happy with this. Review: Review of GravityLight GL02 Home System - Review of GravityLight GL02 Home System 1.) It's not for everybody. What it does, it does quite well. Their stated purpose is to reduce dependency on kerosene for task light at night. 2.) Larger than expected. It comes shipped in an 11 x 9 x 6" fiberboard box, well packed. The box comes in at just under 4 pounds. Mine came inside an desertcart box. It would have survived most shipping carriers, including airport baggage handlers. 3.) I could not quickly find a place to hang it high enough in my house to get the claimed 20 minutes of run time. My response to that is 'so what', 12 to 15 minutes is not a problem. It looks like an 8 foot ceiling would be perfect for the GravityLight. 4.) The unit appears to be very well built. Without disassembling the unit, there was nothing which would be a failure point. The cords and beads are quite sturdy, the bag for the weights is exceptionally strong. The company's plastic people did an exceptional job. 5.) The light put out by the unit is, frankly, not what I am used to as a USA city person. About 15 lumen with a color temperature of 5000K and respectable Color Rendering Index of more than 70. It is more than adequate to read by and to do similar tasks in an otherwise dark area. I would not recommend cross-stitching on black aida cloth using this light. 6.) It will not charge a USB device. The nominal output is 2.7 VDC 0.031 A, 0.085 W. It was not meant to charge USB devices, get a solar charger if you need to, this will not do the job, it was not designed for that. It does provide adequate lighting to read and do other tasks. 7.) Pricing - I do not know the actual cost of kerosene in Kenya nor do I know how much lighting a liter of kerosene would provide. I cannot therefore provide a payback time for this unit for replacing kerosene. I can presume that the GravityLight would be infinitely better than the health risk of kerosene. Much better. 8.) Yes, I would buy it again and I would recommend it with caveats to others. ## Features - Self-Powered, The Gravity light Uses Gravity To Create Clean Energy - Includes 2 Led Lamps With Lamp Brightness Of Up To 15 Lumens - Hang In Any Non-Electrified Space For Instant Lighting - Country Of Origin: United Kingdom ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01M7SM0KE | | Additional Features | Rechargeable | | Brand Name | Deciwatt | | Connectivity Technology | USB | | Customer Reviews | 4.4 4.4 out of 5 stars (160) | | Finish Types | Painted | | Included Components | GravityLight GL02, Paper Bag, SatLight, SatLight Power Cable, Zip Ties | | Indoor Outdoor Usage | Indoor | | Item Dimensions D x W x H | 13.78"D x 5.91"W x 94.49"H | | Item Type Name | GravityLight GL02 Portable Self Powered LED Lamp | | Item Weight | 2.6 Pounds | | Light Source Type | LED | | Manufacturer | Deciwatt | | Material Type | Plastic | | Model Number | GL02 | | Mounting Type | Floor Mount | | Number of Items | 1 | | Number of Light Sources | 2 | | Power Source | Battery Powered | | Room Type | Garden | | Shade Color | white | | Style Name | Modern | | Unit Count | 56.0 Count | | Voltage | 120 Volts | | Water Resistance Level | Not Water Resistant | ## Product Details - **Finish Type:** Painted - **Item Weight:** 2.6 Pounds - **Product Dimensions:** 13.78"D x 5.91"W x 94.49"H - **Shade Color:** white - **Style:** Modern ## Images ![GravityLight Home System GL02 Portable Self Powered LED Lamp, 56 Piece - Image 1](https://m.media-amazon.com/images/I/71iakOvdlTL.jpg) ![GravityLight Home System GL02 Portable Self Powered LED Lamp, 56 Piece - Image 2](https://m.media-amazon.com/images/I/71+3-0kAloL.jpg) ![GravityLight Home System GL02 Portable Self Powered LED Lamp, 56 Piece - Image 3](https://m.media-amazon.com/images/I/61Mkgub-c-L.jpg) ![GravityLight Home System GL02 Portable Self Powered LED Lamp, 56 Piece - Image 4](https://m.media-amazon.com/images/I/71YwNj5fE-L.jpg) ![GravityLight Home System GL02 Portable Self Powered LED Lamp, 56 Piece - Image 5](https://m.media-amazon.com/images/I/81Vjm+-PMqL.jpg) ## Questions & Answers **Q: Is it "noisy" when the pulley is moving? Those beads look like they would make a racket moving through the gears.** A: The unit is very quiet when in operation.the chain only makes a sound when you use it to pull the bag back up. Otherwise it's virtually silent. **Q: Is this still being produced in Africa and supporting the Indiegogo campaign?** A: I believe they have two production sites, one in UK and one in Africa. The one purchased was likely UK for North America market. The actual light is now in service in a remote area of Burundi and is receiving rave reviews. **Q: Can I turn off the main light and use only one satellite lamp?** A: Yes, you can switch off the main light and use only the sat light(s). Hope that helps! **Q: based on the video it appears there is a bit of flicker in the light. is it noticeable to the naked eye?** A: I put a 15lb dumbbell in the bag and got a nice steady light when it was running: 1, 2 or 3 of the lights - no flicker that I noticed. I plan on getting a second unit I like it so much. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to use *by B***Y on December 4, 2017* Quite an interesting device!

It performs just as described. I modified mine to run off of a water wheel and I can get up to six hours with the method I'm using. You can see it at bclifters. I show what two satellite lights look like in my garage. They provide enough light to read and work under and light up a large portion of the garage. Raising and lowering the 20 to 25 pounds to run the Gravity Light is very easy. They have done a great job of designing around the possibility of chains getting tangled. Over all a great product, 20 pounds, at eight feet, for 20 minutes of light is just about right. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/37706950-gravitylight-home-system-gl02-portable-self-powered-led-lamp-56](https://www.desertcart.pl/products/37706950-gravitylight-home-system-gl02-portable-self-powered-led-lamp-56) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-23*
