Pixi Lighting just released a 1'x4' fixture with a 4000 K color temperature that operates at 120 V. Illumination comes from LEDs edge-lighting the face of the luminaire. I tried their 2700 K which was too warm for my taste. Until now, the only 4000 K model they offered required 240 V.

As far as I know, these are only available from Home Depot's web site in the USA.
