This may be a simple answer, may not. Is it worth me converting my LED MR16 lights to GU10? I ask because everytime I have gone to buy MR16 bulbs, there are none in-store yet huge stocks of GU10's. Even when I look at the shelves across the split of, the majority (I would say circa 90%) are GU10's. From what I've read, but happy to be correct, is that there is no savings benefit regarding power drawn switching. When comparing price of bulbs however GU10's do seem cheaper than MR16's, but with the longer lifetime on both, is it worth me switching to GU10's?
