Why do they all hum?

Because of the small circuit in the base. If you have a knackered one saw
the base up and have a look. The cheap crappy made ones by Philips I have
buzz like mad. It's the small transformer inside at fault. A load of
Philips energy savers sold in Morrisons had to be recalled due to a safety
problem a while back. Most people were sent replacements if they got in
touch and quoted the bar code number etc. The light would flicker slightly
when OFF if the slightest current appeared between neutral and earth. I do
mean really tiny.

Fluorescent is out now - make way for LEDs.

We'll see. I'm not convinced.

Blimey, a fluorescent bulb is pricey enough. How much is an LED one going to
be?

Fluorescents are 47p.
A LED one should be as cheap in a year or three.

True. I had a few very old Philips ones that hummed. Now gone, replaced
with cheap chinese made ikea blinders...

Never a safety problem. That is a myth.

Thats a victory of marketing over fact if ever I saw one. LEDs have
never come anywhere near fluorescents in performance for the entirety
of their existence. While we dont know which will win out in the long
term, all the evidence points to it being fluorescent.

It's 49.5p (99pBOGOF) for 11/18W philips ones in Morrisons.

That's funny, my experience is the exact opposite.

The philips ones were *very* old, and humming with a rasp was noted
towards the end of almost an 7 year life. My cheapie Ikea's 11W take an
age to warm up but when they do, staring at the bulbs is painful. I've
got two of those in a three bulb fitting - I daren't add the third :-(

Hi,

Why not get more Philips? The 'softone' ones are pretty good IMO.

cheers,
Pete.

There are/were philips ones that are basically conventional ballasts,
with the tube wrapped round the inductor, and a little starter, all
inside a glass enclosure.

Not 'electronic' ballasts in the conventional sense.

Will probably do when/if this room gets redecorated, got more recent
Philips bulbs elsewhere in more critical areas and they are fine. But at
the moment one bulb missing out the fitting is a minor blot on the
general mess of everything else, and I'm curious to see what the IKEA
CFL bulbs do at near the end of their lives. (shhhh... don't tell me!)
