Finally arrives after going missing for 2 weeks. Cheap looking light. Courior provided proof of delivery from 1 month ago. Wayfair accepted this even though I asked for meta data to prove it didn't arrive. Without question, they accepted. How odd. Still didn't offer to send replacement, or refund. Just kept pushing back to wait another day while they investigated!! Andy from customer service sorted, and still receiving mail saying we will investigate and get back to you!!!! 
Well done Andy, Wayfair customer care, very very poor
