Always have Longclaw within easy reach when you pick up this Game of Thrones Longclaw Desk Lamp. Reach over and let it shed light on your situation at hand. Everybody has a lamp from Ikea or Target. Only you have a lamp that looks like somebody drove a sword into your desk. But let’s be clear – it won’t drive away ALL the darkness, because it maxes out at a 60 watt bulb. But it’ll definitely make you feel a little safer from wights in your little corner of the world.
