I have an 8 foot flu in my kitchen have noticed it does occasionally struggle to strike especially if its chilly in warmer conditions it starts with little effort. I think very old 8 foot fittings had a series condenser between choke and mains if this loses its value it will effect starting. Thankfully my kitchen one is a bit more modern so just has a choke and starter of course. One interesting odd thing I've noticed is that the twin 4 foot 36 watt tubes in my workshop are dim and flickery when cold but the high frequency tube on the other side of the shop don't flicker with the cold just an observation
