A dimmer switch would do the same thing, sure, but having two different light sources working off one another would provide some interesting room lighting. The Butterfly Light is just a concept at this time, though quite an elegant one.
Lighting like the crystal table lamp by Qis Design has the ability to change the color of light from functional white to a warmer color to set the mood. But customizable lighting color doesn’t stop at warm or cool light. A spectrum of additional colors is often part of the package.
These fixtures are subtle and can be directional, and can be connected to dimmer switches to give a range of light from subtly dim to full brightness to illuminate an entire room.
These unique lighting fixtures out of Germany reuse old dead light bulbs to create dramatic sculptural lamps. Bulbs Unlimited sells kits that let you create fixtures like the ones pictured here from your own recycled bulbs.
