Please advise if I should go for Low Voltage (transformer type) or Mains powered downlights in my new Loft conversion? I know they must be fire rated as there is not much room above the fittings. As far as i can see, the GU10 (mains) have a wide variety of bulbs to choose from including LED's and are probably cheaper.
On the other hand the MR16's (Low Voltage) all need a transformer and must have aluminium reflector type bulbs and the overall running costs (including the replacement of non working transformers) seem to cost more.
Please can someone shed some [b]light[/b] (no pun intended) on this subject.
