The lamp has a very unusual bulb with it.  I do not know if I can replace it, when needed with a conventional bulb.  Can you let me know the answer to that?
The instructions were quite inadequate.  Where to touch the lamp to make it work.  I assumed it would be the base, but the only way it reliably turns on and off, and dims, is from the top of the lamp.  I can only assume that is what is intended????
