If you've been looking for a a dramatic centerpiece for your backyard, Anglepoise has exactly what you need. Their Original 1227 design takes the Giant verison of the lamp and gives it an outdoor update. The design swaps out the floor lamp base for a wall mount and because of its adjustable design it can work in spaces both large and small. And if you're wondering about the light source in outdoor use, it's IP65 rated with a waterproof casing and the cable is covered in silicon rubber in case it starts to pour.
