We are currently having a new kitchen fitted, it's galley style 4m x 7m we have two sets of these lights so six bulbs total, the recommended bulbs are 4.5 led candle bulbs, will that be bright enough? I think that's equivalent to 40w in old style bulbs which wouldn't be bright, but 6 of them in a fairly small space? Ceilings are high if that makes any difference, and plenty of windows/natural light during the day, so it's for evenings.
