Christmas tree candles

    Cordless Christmas tree candles are convenient since you won’t have to worry about the hazard of flames or the hassle of tangled electric cords.

    Each PVC candle will come with a molded crystal “flame,” holding a single LED which flickers softly like a wind-drawn wick.

    Located at the candle’s base is a powerful magnet that attaches to a swiveling green spring clip. An IR remote control will rule the candles within a 4-meter radius, setting them to blink or illuminate continuously. A dozen will cost US$49.95.

    Wasted LED watch

    Also known as the Kisai Wasted, it comes in two colors — black and white. It boasts a smooth translucent lens through which you will see the mysterious layout of time. It is USB rechargeable. It takes around 3.5 hours for a full charge which will last for around one month. You need to touch the button for the twisted display to come to life, where the current time will flash for a short time.

    You can also initiate a programed animation between 6 p.m. and 12 a.m., where all lights will slowly illuminate the screen and then go out every 15 minutes. It costs US$85.09.

    Logitech keyboard K750

    It is the first light-powered keyboard, which will charge itself up whenever there is light, even when indoors. When you leave the Logitech Wireless Solar Keyboard K750 in total darkness, it has enough power to work for up to three months before requiring some sunshine to replenish its reserves.

    K750 is also PVC-free, boasting a fully recyclable packaging. It measures 1-cm thick, and looks good with its rounded edges and thin profile. It costs US$79.99.
