How much does the fixture weigh? Will it dim on a dimmer switch

This light is about 4.25KG after packaging.\"It depends on the bulbs you use. If you use regular incandescent bulbs, they are surely dimmable. But if you\'d like to use LED bulbs, then you need to get especially dimmable ones.Besides, please pay attention that the dimmer switch needs to be installed by your electrician.\"
