I can't wait until LEDs come down in price to around the $8-10 range. For probably 10+ years I've been using 5 watt CFL R-20s for down lighting in my soffits. I run the dusk to dawn and there are 13 of them around the house, so going incandescent is out of the question. But those little sucker put out enough light at night to light up the walk around the house.
Here are a couple of photos I took trying to get those nighttime realtor shots that you see in better real estate listings. Tough to do with a cheap point and shoot digital camera.
