I'd change that fitting for a "Viper HF" from TLC.

Instant on, great light, not expensive. I've got one in the kitchen.
Can't get these from DIY sheds yet which is a shame on them ...

I replaced 4 twin fittings around the house with similar HF fittings
from TLC and they made a big difference. They appear to come on at full
brightness instantly, although using a light meter they do take a couple
of minutes, but this isn't actually noticeable to the naked eye. Much
more friendly than the older style of fluorescent. I was expecting
more RF interference from them, but this hasn't been the case, if
anything they are quieter. The only slight issue was having to go and
collect the tubes, for some reason they will not courier these! :-)
