Never used, vintage purple Tensor CL1 computer light that is designed to be mounted on top of flat surface and extend out flat for 22 inches or in an angle shape of 13 inches both ways. The light also can pivot from straight down to 90 degrees toward the front or back with any point in between for the pivot of angle conformations. Tested and it works with a double tube 13 watt fluorescent bulb. This was found in a storage cabinet after an estate clean out so it is a little dusty, but it works. I found two listings on eBay for $32.38 and $39.99 and another listing on Mercari for $39.95 for this model lamp new in the original packaging.
