They added one that's outside the fence so I counted 10. I lifted one end and I'm guessing they are about 300# each, but sure to have some copper and motor in them(if the theives don't take it). Light fixures about a ton after removing ballest, maybe a little more. Rec'd light cans should be aluminum not a lot of weight there tho.LOT'S of plastic and bulbs, one would have to consider throwing pigtails on some of the fixtures and reselling them.
