Replacement for 8ft fluorescent light

[ringer]

Customer has contacted me saying he is having trouble finding replacement tube for an 8ft fluorescent (marked 125W/23 92inch long according to him)
Am I right in thinking that it is impossible to get 8ft tubes any more? If so what can I suggest - replace it with two 5ft battens? Or a 5ft twin batten? Or is there a suitable replacement tube available? Denmans catalogue says they do a 8ft 100W T12 Halophosphate tube (£19.55+vat!)- is this a suitable replacement?
As you might have realised, I am not an expert on fluorries!

that 100watt T12 seems to be a retrofit replacement tube for the older 125watt-so it may do the job


if not i'd prob look at the newer T5 HO in 54watt or 80watt
