What's the current state of play with these? Having just had to replace
yet another from the array of allegedly long-life 35W tungsten MR16s
which festoon our kitchen ceiling :-( I'm interested...

What wattage do you realistically need to replace an 35W conventional

Anyone made the 'jump'?

Thanks
