There are tubes out there that are simply plug and play but they are expensive. IMHO, it's way too easy to change out the existing fixtures with LED strips and the result is excellent. Over the sink I used four strips whereas in the bath I only used two. The nice thing is you can start with two and add as many strips as you like depending on your preferences. Sort of like changing a 60w bulb with a 100w one. Here's what I used:
Step One: Click on the link below and watch the video. There are several but this one I found to be the most informative. It's by RVGeeks. It's old but IMO, the easiest and has the best volume etc.
Step Two: Purchase your LED strips. I bought mine from Amazon. These are the closest to the original color and brightness of the flourescent tubes.
SUPERNIGHT (TM) Warm White 5M / 16.4FT 5050 SMD Flexible LED Strip Lights 300 leds or 60led/m LED Light by SUPERNIGHT $11.98
ZITRADES 10MM 2PIN 10PCS LED STRIP CONNECTORS FOR 5050 SINGLE COLOR LED STRIP BY ZITRADES $7.98
Step Three: I removed the fixture as it's easier to work on if it's on the table rather than in the air. Remove the ballast and all the wiring as per the video. The only thing I did differently is the adhesive they use on the back of the strip is inadequate. I applied double sided tape from Home Depot first, then peeled the backing off the LED strip and put it in place. In the bath, I put the LED strips on the fixture but in the kitchen, I put them on the fixture and the ballast cover.
The only mistake I made was not ordering enough end connectors. I bought ten but with 16ft of LEDs I should have bought at least 20. Don't pay for shipping twice.
Good luck with your project. If you need pictures or have any other questions, feel free to ask either here or send a PM.....Dennis
