Very true. The technology is growing by leaps and bounds almost monthly.

That's funny. I tried them too and my living room window stood out. The 
contrast made my window look blue. Any thoughts I had that the lights 
were too blue were dashed when I was taking a shower one morning before 
dawn and I saw a glow in my hallway. "It is WAY too early for the sun to 
be up," I thought to myself. It turned out to be the daylight bulb was 
on. Fooled my unconscious, so it must have been a close approximation.

Philips new Rebel LED emitters come in cool white, warm white, and 
daylight colors. Of course the phosphors necessary for anything other 
than the daylight color reduce the lumen output somehwat, but there are 
warm white LEDs that are still in the range of 75 lumens per watt. They 
would make ideal under-cabinet lighting, and shower lighting.
