Hi All
I recently fitted a pair of new light fittings - ceiling things with
3x G9 halogen bulbs in each fitting. Each bulb has an opal glass surround.
The fittings were supplied with (frosted) 40W halogen G9 bulbs.

I'd guesstimated that the resultant brightness would be greater than that of
the old fittings they replaced, but was a little disappointed with the
result. However one of the bulbs as supplied was faulty, so I bought a
replacement pack; 2x 40W clear G9 from B&Q (yes, I know, but it was a
Friday night...).

The 'B&Q' bulb (mfd. by GE) was significantly brighter than those supplied,
to the extent that I bought a couple more packs and replaced the lot. I'm
now happy with the resultant brightness.

But I'm wondering; is the increased brightness because the GE bulbs are
clear, and the originals were frosted, or is it because the originals are
cheapo no-name ones made in China and with a possibly dubious wattage or
efficiency? I'm interested to learn if there's such a difference...

Cheers
