Tenant replaced fixtures and they don't match existing decor

[Robin Ryan]

Hello,  My long-term tenants replaced one of my set of matching ceiling lights with a style they prefer.  They discarded my contemporary style light, which was a match for the light in an adjacent room and they installed an "antique style" of their choice.   Now they have moved out and I would like to replace their antique style with a contemporary one.  The lease says they can not make any alterations without approval, but they made many alterations.  Can I charge them for the cost of replacing their antique light with a matching light?  Thank you!
