We used to have a saying at the dealership about these. "One thing about the DROP or TROUBLE lights, if you ever drop one, you will have trouble with them forever."
They also have a tendency to cause instant second or third degree burns on a sweaty arm.
I'm still LOL at this description - "it's main purpose is to consume 40-watt light bulbs at about the same rate that 105-mm howitzer shells might be used during, say, the first few hours of the Battle of the Bulge. More often dark than light, its name is somewhat misleading."
