Vintage F15T8 Fluorescent Desk Lamp

Here is a 1980s fluorescent desk lamp that I got from a thrift store earlier. It uses a single F15T8 fluorescent tube. The tube it came with is a non-original modern GE F15T8/CW. The desk lamp was made by Inter-World Enterprises and was made in Taiwan. It is manual preheat, which is similar to regular preheat, except you act as the starter. You hold down the on button for a few seconds to preheat the tube, and then let go to strike the arc. This method of starting is common for lamps like this.
