Review on 🔎 F13T5 CW Fluorescent Counter Pack - Optimize Your Search by Dang Esq

I wasn't quite sure how to measure my lightbulbs and neither measurement came up with a good round number. The old bulb has no length, only F14T5. These bulbs do not match my lamp. These bulbs: The glass tube is 19 3/8 inches long. To the ends of the metal cylinders - 20 1/4 inches. Apparently this is known as the 21 inch bulb. The light bulbs I need are: 20 5/8" long glass tube, 21 1/2" metal barrel ends, 22 1/8" pin ends. I might leave a no star rating as I couldn't actually use light bulbs, so I have no idea how they work.
