This light came to exist out of simple need: the central ceiling light in my workspace does an awful job of illuminating my desk. So, I dreamt of an ultra-simple form factor, a suspended cylinder, casting light forward and down. As it turned out, the cheapest and simplest way to get a beautiful piece of 2" hardwood dowel was this maple rolling pin.
I created the LED channel by securing the rolling pin in an open box, and then using a router template to create a flat seat for the lights. Because the channel is off-centre, the light is only cast downwards and towards the wall. To avoid putting stress on the LED/solder joint, I created a strain relief loop for the electrical suspension wire.
