Light bulb style Crookes radiometer

This is an ultra stylish and unusual light bulb shaped radiometer.

It has a chrome finished wire stand and screw end lightbulb style base and a filament shaped central vane. Radiometers measure light intensity by spinning in accordance with the level of light which hits the small square vane panels.

The more light it receives the faster it spins as more energy is being received. Place near a window or under a direct incandescent light as the vanes only rotate in light. A great gift and educational piece.
