Shouldn't be a problem; these are sturdy tubes. I have an 8-tube clock and every 30 seconds it displays the day (eg, SATURDAY) and the date (eg JAN 30). No signs of segments weakening after several years. I have a PIR sensor so most of the time the display is running a walking segment pattern (1 segment of 1 tube). The ^ symbol is rarely used and shows no signs of poisoning. Tubes are direct-drive with no PWM dimming, and there are current limiters to keep the segment current and total anode current within datasheet limits.
