This is a pretty chandelier. Take your time, it takes awhile. I, like others, unwrapped each crystal and left it grouped per length, and numbered per instructions in the flat they were packed in. They do alternate sizes per circle (ie 67, 89). Packing was great, with 5 extra crystals of varying sizes included. The 5 halogen 40W bulbs are plenty bright enough to light up a room. Having a dimmer helps make a beautiful glow.
