The Satechi Touch USB LED Lamp is a table lamp designed to work with almost any bottle. As long as the neck of the bottle is big enough to accommodate the lamp, then said bottle can be used as the base. Changing the base to suit your decor is as simple as pulling the Satechi Lamp out of the neck of one bottle and placing it in another.
The lamp is powered via a USB port, with both USB 2.0 and USB 3.0 supported. Once plugged into a USB device or USB wall charger a single touch is all that's needed to turn the lamp on. The lamp consumes just 1.2 watts of power, making it very efficient. The downside of this is limited brightness, meaning this product provides mood lighting more than direct lighting strong enough to allow it to replace a traditional table lamp. The LED is rated for 50,000 hours.
The novelty factor of this product is being able to change the base of the lamp at a moment's notice. You could literally change it every time you acquire another empty bottle, or instead use a bottle that means something to you. I can imagine buying particular bottles based on nothing more than how it will look as a lamp once the contents have been drunk.
The Satechi Touch USB LED Lamp costs US$24.99 and is available now from the Satechi website. The video embedded below shows the lamp as it looks inserted into various styles of bottle.
