Those are rated at 4100K , that is a cool white light, not exactly
what you want in a kitchen as things will apear grey-your hands and
food, 4100K is a good workshop light. A 3800K or Kelvin light is warmer
and nicer, food looks real. Also those only are putting out 30-45 LPW
-Lumen per watt. T-8 tube vs T-5 have more choises and go to 110 LPW,
or twice as efficient. Go to HD and there are T-8 fixtures with warm
white bulbs you will like better. K-or Kelvin is the color temp rating,
how warm the color is and how nice they will look. I found nice T-8-warm
white 3800K at HD or Menards. Its all in the bulb.
Forget LED they are 17-19 LPW same as incandesant and way to pricey.
Yes colored LEDs are most efficient , just not white yet
