How about using led? EW profile, maxlite, UniLume are possible choices. They are all dimmable. The UniLume has it's own on off switch.

I'm another in the "as much as I could get" camp for light under the cabinets. I like a lot of light when I'm working, and I don't have much interest in "mood" lighting. Mine are xenon with a high/low toggle, so I can have a softer glow if I ever want one. This is a 42" cabinet and we have three 12" bars (6 lights total). Got lucky - Lowes was closing out of the White and I got them for $8 each instead of the $24 regular price. Now they only have the black model in stock.

I don't know how the IKEA LED strips compare with the non-IKEA ones but I wasn't drawn to them, and I'm pretty pro-IKEA and value driven (as opposed to low-cost driven, that is, I love lower cost but only if it's a good value). I suspect they are just LED tape strips, and I had decided I wanted bars and not tape. As for installing lights inside a piece of furniture, have you considered the stick-on lights that you can put anywhere and that are either battery-operated (so you can swap out batteries when the lights dim) or LED? They are usually sold in 3-packs at Bed Bath, Home Depot etc. and are not expensive, we put them inside our last kitchen's dark cabinets and they really kept us sane when looking in the back (and in our new kitchen we only did drawers and pull-out cabinets on the deeper bottoms, and regular cabinets up top, so we don't have that issue anymore). Follow up - I wavered between Environmental Lights and Juno, both with a dimmer, and ended up having the Juno's installed and decided I hated them, but couldn't afford to uninstall them and install the Environmental Lights, so returned the Environmental Lights and lost a restocking fee and shipping but was impressed with Environmental Lights overall and how they were helpful and customer service oriented and would seriously consider buying from them in the future - but I can't speak to how the lights would have looked or worked. As for the Juno's, I now fairly well love them, they are fully dimmable piece by piece and turn off piece by piece so the look is customizable from hour to hour, and when all 3 fixtures are turned on at the wall switch and fully "on" the light is brilliant and dramatic. So I'm fairly happy with them but not thrilled with Juno overall - the Home Depot dimmer-dial model I bought has NO diffuser which really hurts the eyes when used with a shiny quartz countertop (I used the Environmental Lights diffusers out of frustration), and Juno's customer service people had no fixes and no suggestions for this problem, and basically wash their hands of these models since they are the "Home Depot brand". Plus Environmental Lights responds to emails on weekends and Juno has no customer service outside of business hours. Overall while I like the Juno lights fine, I prefer Environmental Lights as a company.

Yes. Having the lighting be all different colors create an odd atmosphere.
