The “First Light” from Post Fossil is the first weight-driven light that I have ever seen. It uses a similar mechanism for generating electricity as one would normally find turning the hands of grandfather or cuckoo clock. The difference is that the gradually falling weight is used to turn a set of cogs and gears and generate electricity.
Having never seen the clock in action we have no idea how much light it is able to generate or how often it needs to be wound, but the concept is nothing short of awesome.
From Post Fossil:
“first light” is a sophisticated reading lamp which is powered through a weight and cog wheels just like a clockwork. The power does not come from the socket but is produced directly in the body. This traditional mechanism seems to be floating between the edged rack. Through the glassy lampshade the movement of the cog wheels is set in scene nicely. “first light” is a lamp for bon vivants who like the conscious act of winding up.
