How would you like a tube light that expands into the length of your holder? Something like one standard tube that fits all sizes. So if you have a small width holder, let the tube stay tightly spiraled. Need to fit it to the longer size? Expand the spiral! The idea is pretty straightforward; the only cause for concern is the kind of materials that will be used in the construction of the tube light. Any thoughts?
