If you’re looking to shave every last cent off your next electricity bill then this gooseneck lamp is for you. The lamp is so energy efficient its eight white LED lights are powered by the trickle of electricity flowing from a RJ11 socket – or garden-variety telephone socket. This means that, even if you’ve fallen behind on your electricity bill and the power has been cut off, you can still enjoy some late night reading.

If the only RJ11 jack available is already being used by another appliance – say a phone – then you’ll be left in the dark, as the light isn’t able to connect to a regular power point. Even the battery compartment of the lamp has been rendered a waste of space. The lamp doesn’t appear to be a winner in the looks or build quality departments, but what do you expect for US$4.69?

Sure, the phone companies probably won’t like it, but you could argue it might provide an (extraordinarily minor) reason for people not to ditch the land-line in favor of relying solely on a mobile phone.

The 8 LED RJ11 Lamp reaches around 27cm (10.5”) high and weighs 74g (2.6-oz). It is available now from Uxsight.
