It is by a circular fluorescent bulb and lights the first time, every time. The colors are perfect and NOT as the pictures show.
The original colors are deep and rich. Now for the bad part. It has a crack in the face of the glass that runs from 2 o'clock, right down through 6 o'clock.
There is NO glass missing and is very tight, with NO movement at all. The motion is very iffy, and works when it wants to, and just assume it will need some attention. This is the way I bought it.
