"These are cheap bulbs but find they outlive Osram MR16's. Also more responsive on a transformer than other manufacturers with less delay when switching on. I've now permanently moved onto these from Osram's. Not down to cost but reliability"
"Might be bad luck, but these lamps are very unreliable. Used up five in quick succession. Two failed with a month. Another two within six months. The only one left now buzzes when on. Not impressed with Halolite brand"
