Just seen for sale light bulbs for the house, each one consisting of 15 of
those LEDs. They are going for about £6 each and are rated at 2500 hours
lifespan.

Anyone any experience of these....advantages and disadvantages?

Are you sure that you've not missed a 0 off the end.

LEDs are supposed to last for years, even with regular use.

What type of fitting are they?

No so with the ones in lamp applications. They run hot which shortens the
life considerably. How long depends on whther they used decent quality LEDs
(eg Nichia, Luxeon, Cree and a couple of others) or some ****e cheap chinese
rubbish.

My experience with anything costing 6 quid involving LEDs has been the
latter - watch them start to burn out one by one after a month or two.

Cheaps LEDs are even worse than cheap CFLs...

Well yer bog standard tungsten bulb generally has a 2,000 hour life
so sick squid for an extra 500 hours is not very economic...

Sure you don't mean 25,000 hours, most specs I see for LED lamps
quote around 50,000 hours.

Well, you've given almost no info on what you're talking about but at
£6, almost certainly completely useless.

You have to get up nearer £100 to get anything viable at the moment.

I've had something similar in my fake gaslamp outside for several
years. They are rated at 12 volts DC and I ran them off a car battery.
But I had a charger on the battery so the voltage was a bit high and
some of the LEDs got a bit dim after a few weeks. I've put a
resistance in series to bring the voltage down.
At only 3 watts there is not a great deal of light.
