All right, Arfa? Good to have you back.
Yeah, I don't have answers to your questions, but I do know what
you mean about those bulbs. The aging CFL I've got in my bedroom is
utterly appalling; it takes ages to brigten up; sometimes I've walked
past the bedroom having just got up, and thought I hadn't actually
turned the thing on, it's been that dark! I mean, I could just buy a new
one, but I never remember!
What is the mechanism by which they take so long to get going? Is it
some mercury vapour thing whereby the mercury takes ages to go into
gas phase? As you can tell, I have no idea what's going on inside
these bulbs. I thought the pressure was so low that the mercury was
always gaseous even at room temperature, but I'm not sure. That's
pretty embarrassing.
And is the warm-up time affected by age? I don't see how it should be,
but I don't think they're that bad when new. It does seem to be
age-fellated. RELATED. Sorry - she's gone now.
Also, how is it that the light output diminishes with bulb age?
Cheers, anyway.
Hi Fleetie - good to hear from you. Trust all is well with you ? Go have a
look at

It might help you out with the concept and operation of these dreadful
devices.
Happy new year to ya, and stay in touch. Always glad to see you pop up on
here.
