I realise that they are horrendously expensive but I think they are worth it.
They use a lot less leccy than fluorescents and last a lot longer too.
I reckon that the ones I have will last for the remainder of my lifetime
, and I won't need the hassle of climbing steps to change a bulb (which matters when you get old and decrepit
)
I have never seen any that give out more light than the old 75 watts but have read that more powerful ones have been developed in USA and will be available soon.
