It is not always easy to know how to measure your tube correctly, should it be including or excluding the pins? The first thing to keep in mind is that the wattage and the length of your tube correspond to each other. It is therefore important to purchase your new tube with the same or replacing wattage. For example, if you currently have a 150 cm fluorescent 58W tube, your new LED tube should therefore replace 58W and have 150 cm length.
You can always find the exact measurements in the data sheet of each product. There you can also see how it has been measured. For all our Noxion products you can find this straight on the website by scrolling through the product pictures:
