They're from the dark side, so it makes perfect sense that Darth Vader and his trusty Stormtroopers would need something to light the way.
And what better device than lamps shaped like their very own heads? These fantastic LED-powered lights are available from thinkgeek.com priced at $19.99 (£12) for a small and $49.99 (£30) for a large. The Darth Vader one emits an evil red from his eyes and grill, while the whole Stormtrooper helmet lights up white.
Naturally, they don't use the Force for power - just 3xAA or AAA batteries. Much less to go wrong with those.
