Instructions vague and European (according to electrician consulted). Stateside: Connect neutral black to blue wire. Connect live white to orange. If needing ground wire, screw to center nut on cap. Otherwise once that was advised to us, easy assembly. Looks fine. Casts steady light, not streaky with shadows like some overhead lamps. Wish it had a remote for dimming; can toggle light temps with light switch. Suits its environment.
