Playing games or watching movies in the middle of the night can be a strain on the eyes, especially if you play with the lights off. And what if you don’t have a backlit keyboard? Get yourself a simple USB LED lamp (they’re available for as little as Rs. 100) and a cheap USB extension cable. Or you can also pick up USB-powered LED strips and attach them to the back of your TV, which, by the way, will usually have a USB port on the back anyway. Another quick tip, in the event of a power failure, plug that USB lamp into a portable power bank and you’ve got a handy-dandy emergency lamp. Sure, you can use your phone’s LED as well, but now you can save it for something more useful, like playing Candy Crush.
