Unable to cast double to Coordinateframe?

Line 27:

x:SetPrimaryPartCFrame(CFrame.new(math.random(-200,200),math.random(50,100), math.random(-200,200)))

What am I doing wrong?

[Edits:]

while wait() do
    local P = Instance.new("Part")

        P.Rotation = Vector3.new(math.random(0,360),math.random(0,360),math.random(0,360))

        light = Instance.new("PointLight", P)
