Lighting question

I am in the uk and i`m interested i making a flourescent light rig and wondered if there is anywhere i can get a 3 or 4 tube holder for 24" tubes ?

Thanks all.

lots of places try B&q ..im sure i seen them for bout 15 quid a pop ...they also have a nice warm and cool white fluro selection at bout 4 quid per bulb :)
