The final version of the adjustable reading light project (see process here). The tubular light shade is made from a single piece of spiraled ash veneer.
The light within can be adjusted and set in place using the knob on the top of the lamp. The adjustment allows the user to choose the ratio of task to ambient light.
For optimum reading conditions the tube is fully covering the light, this gives a nice glow and a spot light under the lamp for the reader.
