The tube length is 585mm without pins, 599mm including pins. The manufacturer specifies a tolerance of +/- 3mm for these tubes.
With fluorescent tubes it is important to check the length of the tube before purchase as different manufacturers have different length of tubes despite being the same wattage.
Some light fittings only work if the tube is rotated to exactly the right position, whereas others work either at the right position or 180 degrees round from that.
