aw shucks thanks!

They don't work very well with those touch sensitive lamps, where you touch it once and it comes on low, then touch it again and it gets a bit brighter, then touch it once more and it comes on full brightness. With the low energy bulbs the lamp just stays the same brightness no matter how many times you touch it.

you are supposed to throw out all your old light fittings that don't work with the new bulbs, and buy new light fittings to go with the new CFL bulbs that you have bought, if necessary also changing your lifestyle to suit the new bulbs and fittings.

Try the Philips Turbo model its almost instant brightness

i.e. also throw out (carefully!) the CFL bulbs that you have already bought at substantial expense, and buy new ones? Pending the requirement to dispose of them too (carefully of course!) and buy LED bulbs at even greater expense, when they get round to making and selling them.

Just poke your own eyes out with a hot poker and stop worrying about it.

You can still get rough service 100W bulbs.

Proper ones.

But they're not as bright as General Service 100W bulbs.

excuse me, rough service and general service???????

aw shucks thanks!

yr welcome!

...and buy LED bulbs at even greater expense, when they get round to making and selling them.

you can buy them now, not in the shops though - they are about £40 plus.

Haitz's Law

...the cost per lumen (unit of useful light emitted) falls by a factor of 10, the amount of light generated per LED package increases by a factor of 20, for a given wavelength (color) of light. It is considered the LED counterpart to Moore's Law, which states that the number of transistors in a given integrated circuit doubles every 18 to 24 months.[1] Both laws rely on the process optimization of the production of semiconductor devices

The development of LED technology has caused their efficiency and light output to increase exponentially, with a doubling occurring about every 36 months since the 1960s

There is a theoretical upper limit of course, and that works out to be around 2 hours at 100 watt bulb brightness equivalent (~1000 lumens) from a single AA battery. Currently it's something like 30 minutes, 25% of maximum possible.

so did you do it yet?

Oh the pain....

got a 3w Led for the shower its about 20w, nice light compared to the original50w slightly dimmer but consistent light.

Waiting for decent led lights.
