SO.....if we just went standard, are we talking 25w, 40w, 60w....?
You don't want an incandescent bulb for this. Their color temp is way too low, it'll bias your eyes to make everything appear blue on the screen. You need a "daylight" bulb, the closer to 6500K (which is what the color temp of your display should be set to also) the better.
As for lumens, it varies based on the distance to the wall. If you have any DVD/BD with test patterns look at the 15% gray, that's how bright the wall should appear behind the TV. That is one nice thing about the Ideal-Lume Pro, it has a dimmer so I could dial it in exactly. Is that worth the 500% increase in price over the standard? No.
