the correct fuses ???
are they on a lighting circuit?? then 5amp mcb/6 amp fuse as a total circuit protection
on a plug in you are protecting the cable perhaps 3 or 13 amp
28w is nowt in real terms assuming 230v as 1 amp at 230v is 230w so 8 28w bulbs are 1amp[224w]

As big-all almost said, why do you think you need a fuse?
If it's to go in an existing light fitting, no fuse required. (Where would you put said fuse?) If you are putting it in new light fitting on a lead with a plug then a 3A fuse should go in the plug.

sorry i should have been more specific, inside the ceiling light fitting it takes the little cylindrical starter fuse.

That is NOT a fuse. That is known as a starter. (It warms up, goes open circuit causing the inductor to "collapse" which creates a high voltage, striking the tube.) They don't often fail, if it has get one the same as the one that is there. (I haven't seen one for 10+ years) But to be honest, I would change the whole light fitting to something with LED's, less trouble.

thanks for reply, problem one unit keeps blowing bulbs after a few weeks of use, i was thinking maybe the starter is not makeing proper contact or soemthing ? no idea, why would a lighting unit keep going through bulbs regarless of brand bulb. i agree should be replaced with led.

TBH change the fitting to a LED unit, miles more efficient, next to no maintenance and gives off miles better light

i agree owners to cheap, rather keep replacing bulbs believe it or not..insanity, but why would the bulbs keep blowing a such a short time..?

Incompatibility, and poor quality of lamp.

A bad transformer, voltage spike, those 4D bulbs are not cheap and not long before they are phased out, bill him for bulbs fit a new fitting

Not your problem, change the lamp again, and send them the bill. Do tell them you know they are wasting money.
