Bit late now but i have only just seen this thread.
Am i right in reading you have a 2x200 watt bulbs in roses at each end of the room? Could you not have just doubled up the amount of roses and fitted some low energy bulbs. I think a 20w bulb is equivalent to a 100w bulb?
Like i said i may have read this wrong or my advice might be duff! :lol: :lol:
