Hi I have a couple of 4ft florescent fittings in my workshop and they are the high frequency type. They are both playing up so I want to buy some new ones and it started off simple but now I am confused. I have a box of 25 4ft tubes so I wanted to stick with the same size but on looking for HF fittings I see there are T5's and T8's in 4ft and one is 36w and one is 28w. My tubes are 36w and my local electrical place has a good price on the fittings but they are sold as the 28w type, does this matter i.e. can I use the 36w tubes in the 28w fittings or does that cause a problem?
Any help appreciated.
