Document: saw this on hgtv. it is better. great lamp-beautiful lighting-soft, but good for reading too. arrived before expected time. thanks!
nice little idea and lamp. It was a Christmas gift, and the person really liked it. Very affordable nice little gift.
don't know if it works. it's powered b y usb,  I wanted  regular 220 plug-in. have no use for this
What a cute idea. This little lamp doesn't have a base. You have to provide your own bottle or vase or other similar container. It should have a mouth that's between 5/8 to 1  inches wide at at least 5 inches tall. Just balance the shade on top and you have your own lamp. Change it up, make it from plastic bottles, glass bottles, vases. It can get funky. I made one with a vase and it's adorable.You'll need a USB outlet to power this.
What a clever design!This little lampshade/LED lamp is a touch light which needs to be used with a bottle or vase (not included). It measures 4" in diameter at the top & 6" in diameter at its base.The frosted shade allows a soft glow from its 4 LED lights to shine through. Even though it provides a soft glow, there is enough light to read by.
We put the lamp in an empty bottle that we have been saving because we loved the look of the bottle. We order a couple of these lamps and have them on our computer desk and on tables in our living room. We had to get an extention for the plug but we love the lamp and the amount of light it gives off. It is also a great conversation piece.
We gave this to our daughter for Christmas and her boyfriend has latched on to it! It is so versatile and looks great with any bottle,  vase or anything with a hole on top. Paired with a USB outlet or your laptop, it goes just about anywhere.
WE HAVE LIGHT ! ! NOW we're talking !! These things are GREAT for backup light when the power goes out! They are also great for camping purposes, as we learned recently at the annual ARRL Ham Radio Field Day! Again using a portable USB battery charger, the lamp stayed lit while it was needed. Need a light for your camper? Kids need a light in the back of the suv at night?
Very unique and quite flexible in its use. The light is enough to illuminate a small room or just to give some light to a larger room.
Very soft light nice for bedside reading and pretty much anything you want to achieve while you're lying down and comfy
