Thats been around for quite a while now and i almost bought one but i have
found that no matter what it still won't point the light right where you need it the most!
I too have fabbed up all sorts of holders/hangers and the light is never pointing where i want it.
The best thing iv'e come across yet is the Craftsman SS 1WATT LUXEON LED HEADLAMP ANY WHERE YOU LOOK THERES LIGHT! AND IT'S ONLY 25 BUX!
