Check the nominal lifetime of the bulbs ... the cheapies are generally
only
rated at 1000hrs, whereas the slightly more expensive ones are 2000 hrs.
BTW
the screwfix more expensive GU10's are made by Osram and are rated at
2000
hrs.
You pays yer money, yer takes yer choice!
Also bear in mind that the main cost is that of the electricity
used, not the bulb. Using a shorter life bulb may give you higher
light output and enable use of fewer or lower wattage lamps, which
will make a much more significant cost reduction than the difference
in bulb prices.

WTF?
50W is 50W in my book!
1000hrs at 50W costs about £3.00 at 6p per kWh.
2000hrs at 50W costs about £6.00.
Also the GU10's that come *complete* with the fitting I reckon have an
average life of 200hrs or less.

Got to agree. Bulb cost domiantes in mains halogens.
LV ones its the electricity - over 1000 hours for sure.
