I also agree that you can't see them when they are on. Our house isn't super traditional, but we have rope lights in the family room and master tray ceilings (put there by builder). No one would know they were there when they are off. TBO, we rarely turn them on except when we want very dim light or for a night light when we have guests (and now for house showings). We thought they were neat when we bought the house, and so does everyone else, but they're mainly a novelty.

I looked at many types of LED under cabinet lighting, bought some and returned it, read reviews for hours and searched online. I came to the conclusion that these Quoizel tape lights are the sturdiest and easiest to install and that is what we are using. On one side of the kitchen the thin wire with the plug will go up inside the cabinet and plug in he receptacle in the cabinet where the microwave plugs in. On the other side we are putting a new receptacle above the sink and will plug them in there as not to have plug in wires visible on the backsplash.

I had very good luck with Lowe's Utilitech (made by Feit) Par 38 dimmable LEDs. The color temp is 3000K and it is very good light. We are on a wooded lot and also have mutable colors so finding the right bulbs has not been easy. Our HD does not yet have the Reveal LEDs. It will be interesting to see how those work eventually as there was a coating in the incandescents that kept them from going too candlelight though they were slightly red. I found the Utilitech to have bright and clear white light. But we are in the Northeast and those bulbs can look different in different parts of the country and in concert with the paint color. This lighting tech transition has not made this easy.

I'll throw in my own two cents here. For starting seeds, I use T8 strips. I have 4 tube fixtures above each of my seed starting shelves, and I use 2 cool white (~4100K), 1 warm white (2700K-3000K and 1 daylight (6500K) in each fixture. I don't have pictures, but my seed starts under these lights look about the same as seedlings started in full sunlight. Seedlings need a much more balanced spectrum of light, and conventional white lamps seem to very work well for sprouting seedlings and in the early stages of growth. The red/blue lights are often misunderstood, and most of the ones on the market have a "mix" that is tailored for growing "medical flowers" from established plants. In that environment, blooms = $$$$, so those lights are made to stimulate blooming with a lot of red light. You don't want to stimulate seedlings to bloom immediately, so red light is not what you really want to put on seedling starts. Looking at aruzinsky's setup, I see 11:1 red:blue. That's really pushing it even for established plants, and not what seedlings really need at all. For established tomato and pepper plants, the red/blue (3:1 or maybe 4:1 red:blue) LED "grow lights" work great. You'll get prolific production from those lights as they really stimulate blooming and fruiting. Just be sure you're fertilizing regimen is adequate for the production you're demanding from the plants. Using the LED "grow lights," I got more cherry and Roma tomatoes per plant from my "basement tomatoes" last winter than from the plants in my garden over the summer. There are some kinds of plants (leafy herbs like basil and cilantro, and woody herbs like sage and rosemary) that you don't want to stimulate to bloom. Those plants benefit from a lot more blue light after they are established. Blue light stimulates leafy growth. The "blurple" LED strips or lights with 3:1 or more red:blue LED's will make cilantro and basil bolt and bloom quickly, without producing much tasty foliage. I'll be experimenting this coming winter with all blue or blue/white(/deep red) LED lighting for my leafy and woody herbs. This comes after a year of failure using the red/blue lights with a high red:blue ratio last year. I had some of my woody herbs die from lack of (proper) light, and my leafy herbs bolted/bloomed early and failed to produce much foliage with the very red "LED grow lights."
