coughed up some electrons that declared:

Anyone used this type of lamp? The image looks like "clear" but
they call them "frosted" ...are they as opaque as "pearl" ones?

Why do they call them "bayonet clip" ...what's wrong with just
BC..bayonet CAP.

Can't see much fundamental difference between that and this:

Which is just a different shape bulb and higher power. These work fine and
have been around for years - I use the 100W ones when I want a good strong
light.

Maybe the former is a concession to trying to make a more energy efficient
GLS type lamp without involving CFL technology???


The former is an energy saving lamp using technology newly developed
by Philips, giving a 30% energy saving for the same amount of light.

The latter is a bog standard halogen lamp which does not include the
energy saving technology.

The energy saving halogen lamps are extensively used by the National
Trust because they retain the original appearance of incandescent
bulbs while saving that all-important 30%. They also have the
advantage of low UV emissions reducing the rate of ageing of things
like upholstery fabric and wallpaper.
