Re: @Tom 38
They might be like LED lamps which are supposed to last the same sort of time.
In lamps, they refer to the led, which may indeed last that long, but the cheap, deathtrap, underrated power supplies they throw in to drive the LED don't last that long. I bought 8 GU10 LED lamps and all bar one are dead after less than 12 months of normal use. Dreadful. They should have to state the lifetime of the whole thing, not just the longest lasting component.
At least the razor is battery operated and low voltage, so as long as the rest of the electronic driver circuitry is rated at 50,000 hours too, they may have a chance for that claim.
