daepp,
Take a picture of the lights in your kitchen and post or email them to me. If you are really running 120W lights you could drop down to a halogen lamp to save energy and get the = light output. Also by using a dimmer on your inc. lamps you will extend their life. Less light output is not a problem if the distribution is good. Using a flood or wide flood helps eliminate dark spots.
Using CFL is one way to go to save some energy in areas where the lights will be used for longer periods of time like dad911 mentions. Some CFL that are retrofits can be dimmed with standard dimmers, or so they say on the package. We have never had good luck with them below 50%. A real good system will require a special ballast and dimmer.
Title 24 in CA now requires a source the meets a lumen per watt spec that only fluorescent can meet in kitchens. There is some great LED product on the market now, but is pricey for the ones that really work. Dimming down to 50% is achievable but below that is dicey. Once LED's have a standard they will meet Title 24 with no problems. I have done several LED retrofits in both commercial and residential applications with great success. Amazing what a 15w LED lamp will do when placed in a properly engineered package.
You can PM if you want some more info. Might even be able to sample you some CFL or halogens.
