I don't have tall ceilings either. I think maybe 10 foot ceilings. He stands around 7 feet. V2 would be shorter because the base is not tall like the V1.
The blue lights on the base of V1 are actually located on the base instead of a piece that goes around the base like in V2.
They are placed inside some of the skulls etc.
There are 2 or three different modes. One of them is always on, one is motion detected, and I can't remember if there is a blinking one. I'd have to check. I may be getting mixed up with the 1/2 HCG scale endo bust.
The one advantage that V2 has over V1 is that the skull lighting is seperate from the base lighting and takes batteries I believe. There were a lot of problems with the V1 eyes not lighting up due to connections not being make from the top to the bottom of the piece. Mine lights up good but I had to take a saw-der-ing iron to it.
