- Color is still a work in progress. LED lights can also have that commercial cool blue tint and other less desirable hues of green or pink, depending on the manufacturer.
- LEDs are more directional, which makes them good for task and spot lighting, but not as general light in a table lamp or ceiling fixture.
- It will also be years before the common LED bulb will cost $20 to $25 instead of $60 or $70.
