Lights are becoming so efficient that now you can buy a lamp that is powered solely by the minute trickle of electricity from your telephone socket (RJ11 jacks). I can’t vouch for the legality of using the jack for something other than a landline telephone but we’re talking about free electricity here people. Free electricity.

This gooseneck lamp has 8 white LED lights in it’s top. There’s no other way to plug it in other than your telephone jack, which you’re likely not using anyway. Even if you are a dedicated landline user, there’s usually jacks that you don’t use scattered about your house. No wattage is listed in the product description but I wouldn’t be expecting too much from this low powered lamp, especially at the $4.69 price point. Anyone out there know how many watts you can get from an RJ11 telephone jack?
