I wouldn't characterize fluorescent dimming as "in its infancy"--it's actually a quite mature technology. There are, however, two factors that effect the market for dimmable fluorescents: 1) It's pretty expensive, and 2) People have tended to prefer incandescent lights for the sort of mood lighting that folks tend to want to dim. Therefore, the market hasn't really developed, and there are a number of holes in the market where one might want a dimmable fluorescent where nobody makes a ballast for the lamp of interest. In other words, if you want a dimmable fluorescent, and there is a suitable ballast and dimmer for your application, and you're OK with the price, then there's no reason not to "jump in." The technology isn't going to dramatically improve in the next few years. All that said, the only dimmable undercabinet light I've been able to find is the Alkco "Little Inch" L2F fixtures. They are available with 10% dimming ballasts that operate using Lutron's "3-wire" dimmers. (I note that because of the response of the human eye, 10% dimming looks like about 32% of full brightness; this may or may not be enough for you.) The "3-wire" ballasts and dimmers require three conductors between the dimmer and the light fixture, whereas normal wiring would require only two, so the wiring has to be installed with this technology in mind. Regular T4 and T5 tubs such as are used in undercabinet lights are one of those "holes in the market" that I mentioned above. The only ballasts I know of for those tubes are the Lutron ballasts for the T5's, which only go down to 10%. I note that Lutron has ballasts for T5HO (High-Output T5's, which are about double the wattage of a regular T5) that go down to 1%. A T5HO at full output seems a bit much for an undercabinet light, though.

I don't know but I want to see what happens. Please, give us updates. I am growing lemon plants from seed just to find out what lemon blossoms smell like. As soon as I find out, I will throw the plants away, and scratch it off my bucket list.

Thanks so much - that does make sense ... and I love this idea for a graffiti wall. I should have realized how far the light would go. A few years ago I raised the ceilings to create a cathedral ceiling in a room and put molding around the lengthwise walls of the room with LED tape uplighting. At the lowest dimmable setting it gently lights from 9 feet up to the 16 foot cathedral area... and when it's higher it could be like daylight at night... so now I'm realizing how much it could wash a wall if the opening was under instead of above. If the height of the wall is 104" and the goal is to wash the entire wall (let's say no art frames... just painting directly on a wall), how much distance would you want for the gap? Would it just be about an inch or so? Or maybe even less? -- Thank you so much - I never would have thought of this and it's perfect.

A friend recently used the GE Enbrighten strips in her new build. They were recommended by her electrician. They are individual strip lights that can be direct wired with one switch, but also has a switch on each strip/fixture to individually control each light (even when direct wired). You can switch the light from soft warm white (3000K) to cool white (4000K) to daylight (5000K). She is quite pleased and I was impressed. She got hers at HD, but would imagine they aren't hard to find.
