Input:
Question: What kind of on/off switch does it have?  Is it a rotary dial on a side-to-side switch?
Document: I am very pleased with both lights. I DO NOT leave either light on overnight or when I am gone.
Expect size and weight variance - I ordered 2, one is just like the pic and about 8" tall and is in my living room - VERY PRETTY, gives off soft light which is ideal for evening TV (for me). The other is lighter in color and about 5-6 " tall and I use it in my bedroom on my nightstand - seems to get brighter after several minutes - is soft light, but bright enough to read and do suduko puzzle.
Answer: no
