I must confess, I've used these to run christmas lights from a porch light. Thankfully, few people know they exist, or it would be a lot more widespread. At least people like us realize those light fixtures were only designed for 0.5A worth of 60W bulbs, and we refrain from plugging more than 5 or 6 strings of lights into them.
Back in FL, alot of people used these to connect a string of christmas lights to post lamps. Purpose of this was to wrap said lights around said lamp post.
