They claim 7000 hours.

In my local Morrisons, the entire basket of them is Edison Screw fitting :-(

In my local one, there are two baskets (of equal sizes) with ES and
bayonet.
I have no idea if there are more in the back.

In ALDI, you can buy Osram's for a quid. I find these light up to
specified output quite quickly - the philips take a few tens of seconds
longer.


Over the first minute, just testing, the philips one seemed brightest
after about a minute.
