I've got 4 LED's in our main bathroom, and we really like them. I also have an LED bulb in our main bedroom ceiling fan light combo. We don't use that one much but I do agree that it takes your eyes a minute to adjust to that one in particular.
We have 4 dimmable LED lights that will be installed into our main living room in the basement once we've mudded and painted. They are 75watt equivelant @ 750 lumens, and use 14.5watts on the highest setting. They have a 32 year life expectancy, or 35,000 hours of use. We chose to do LED lights in that main room since we project 90% of our time being spent in that room, other than sleeping in our bedroom. So, the slight additional upfront cost is easily made knowing the lights are rated for 3 decades; 2+ decades longer than we intend to live in the home. The particular lights we bought were only about $30 each if not less, and have an Energy rebate available.
As far as LED flashlights go, if you have an LED flashlight and are not happy with it - you own a crappy LED flashlight. I've got a several LED flashlights, including several Maglights, and you certainly get what you pay for. I carry a Streamlight PT-2L which has a C4 LED with 180 lumens; it'll blind you - which is why I carry it. I have another light with has a CREE bulb and packs 1,600 lumens, and has an adjustable light spread/pattern. That is an amazing light, but it's not the best for getting a large spread of light. You can't go wrong with an LED Maglight for great light output and adjustability. My favorite Maglight is an LED converted 3xAA unit with a on/off tailcap. It's skinny, beefy, bright as hell, and can pack anywhere I need it on trips. Anyways, I have a thing for flashlights...
