Perfect.
I have had a Verilux natural spectrum floor lamp for about ten years.  I use it every day in my bedroom to read at night.  I finally decided to treat myself to a second lamp in the den where I work.  I looked at all the other brands with similar styles and similar claims, and was surprised to find that the other brands have many, many negative reviews for not working and for ceasing to work after a year or two.  Although the Verilux is generally more expensive than the other brands, I can tell you it is far superior.  It is EASY to assemble: from closed box to functioning lamp took under five minutes, included finding my phillips screw driver.  It works without fail for many years.  I haven't even had to replace the bulb yet in my ten-year-old Verilux!  The light it produces is wonderful.
