... I use traditional bulbs on the stairs and landing because energy saving ones take ages to get to full brightness (unless they are new) - its a matter of safety, I wouldn't want anyone falling down the stairs!........
I have had several ordinary l/e lamps with a ribbed outer glass case [Philips?] which dripped a nasty brown substance after a few months!
I would like to buy more 'quick-starts' but but I can't find them.
Goodness - those heavy conventional ballast lights haven't been made for ages now.The ordinary Ikea ones come on instantly and at a decent (but not quite full) brightness. Ikea light bulbs are very cheap.
It doesn't matter whether they are new or not - they still take a while to warm up. Their final brightness just lessens with age.
There are other technologies becoming available, which don't suffer this problem, such as LEDs.True, although there are some which work with a normal switch which can be set to a handful of different brightnesses by turning the switch on and off a few times. There is no theoretical reason why LED lamps should not be dimmable, but I don't believe the current crop are.They are getting smaller - this is much less of a problem nowadays.A very small amount of mercury vapour, yes. Ordinary bulbs can't be thrown away with the normall glass recycling either. Ikea will take low energy light bulbs for recycling; just as with batteries, a wider recycling network needs to be put into place.Please do - I'll see if I can answer any more points you may have.
Around 3 years ago I bought a couple of 'quick-start' energy saving bulbs. These come up to full brightness instantly. One is on every night in a porch area with no loss of brightness compared to 'ordinary' low energy lamps (I have had several ordinary l/e lamps with a ribbed outer glass case [Philips?] which dripped a nasty brown substance after a few months!). I would like to buy more 'quick-starts' but but I can't find them.
Does anyone know who makes them?
Trouble with led's is that when lighting up your house, they are no more efficient than tungsten lamps, and less efficient than Halogen.
