Unfortunately there is no true guide or key for the under cabinet tubes. As there are so many makes and models out in the market the only way to correctly identify the tube that you have is to measure the tubes including the pins and make note of anything printed or written on the tube itself. With this information we can then correctly source your replacement tube.
