The table backgrounds have a slight hint of blue in the grey, but the page background is real grey, and doesn't look very good. Try getting a bgcolor that's a little bit more blue.
And like someone said, the logo does need to have the text bigger...
Also, the on/off lightbulbs need some work. Usually I'm able to tell right away, without looking at the icon legend, which means on and which means off. This time I had to look close to even see a difference at all... There's only a few pixels difference from what I can see. You may want to get more distinct on/off bulbs so it's not so hard to tell which is which.
