Best 'instant on' CFL bulbs?
 

Getting a bit tired of CFL bulbs that take up to a minute to warm up
too 100% brightness, so can anyone recommend any 'instant on' 60 Watt
(13 Watt CFL?) equivalent bulbs please?

Thanks

There aren't any, sorry.

They are better than they were in the dear old days but the best of
the current (No pun intended) crop are still about 30% - 50% down at
1 minute, and another 30% down after 12 month's service.(All except
"Dynamo" Hansen's, they positively coruscate within seconds of being
energised).

IMV Feit lamps from Costco (& others) are the3 best of a bad bunch

Oh dear, that bad huh?

So we've had these poor quality CFL bulbs foisted upon us and, to make
matters worse, can no longer buy the old 60w non-CFL bulbs.

What a shambles.

best go up to at least 15w for a 60w equivalent.

Trouble is, the run-up time is necessary for the high efficiency.
For fittings I make myself, the 2D compact fluorescents are about
the best in this respect, but that's also because they are slightly
less efficient.

They are better than they were in the dear old days but the best of
the current (No pun intended) crop are still about 30% - 50% down at
1 minute, and another 30% down after 12 month's service.(All except

Agreed. They are the only CFLs I've seen which actually have the
correct filament equivalency printed on them (with 23W = 100W).
They also seem to last very well, including in enclosed (hot)
fittings. The 23W CFL lamps are bigger than 100W lamps, but are
probably the shortest 23W CFL you'll find, and fit in more
existing fittings than any other make I've found.

Also, go for the 'warm' colour temperatu the high colour temp ones make a
room look cold and dark however bright they are when you look right at them.
And our ones (the only kind we could get to fit in the narrow screw size at
the time) rapidly became so dim as to be pretty well unusable.

Hmmm, don't seem to have a Costco near me - who else sells these
'Feit' bulbs?

If you want "instant" starting then you need to buy LEDs.

I have been using compact fluorescent lamps for many decades. Some
of the older ones were noticeably slow to start, especially the old
glass bulb ones, as are some newer ones. These take time to warm up.
However, despite long and loud assertions from some that it is
impossible, I use Philips and General Electric compact fluorescent
lamps in places like stairs and toilets where rapid light is
necessary. These lamps are not noticeably slow to start. As the
lamps last a long time it is not possible for me to say anything
about the lamps now on sale, the ones on the stairs and in the
toilet are at least a decade old.

The exception is the bottom of the stairs. The SES reflector lamp I
tried there was a little too slow to start (another poster has
explained why), so I replaced it with a LED version.

I use the slower starting lamps in places where a slow startup is
not a problem.

Correct.

All a bit empirical that, especially from such a biased source. Please
show us your measurements.

Ditto.

Where do you use the dim ones and what for ?

You coud always try the halogen energy saving bulbs ( look like an ordinary
bulb but with a 'capsule bulb' inside.

What sort of energy consumption do those have? I assume better than
standard incandescent, but are they better, worse, or the same as
incandescent bulbs? And what sort of light do they put out?
(I've just been looking at buying a ceiling light which calls for them.)

Energy consumption as in use or whole life cycle?

Whole life cycle , tungsten filament dash of bromide, quartz inner and
glass outer enevlope steel and mixed metals connectors , not huge
making or disposal energy cost, about 30% better energy wise tghan non
halogen , nice light far better than CFL, CRI100 against CRI80 odd
fro most CFL

CFL glass outer, phosphor and mercury filled inner, tungsten in
filaments, copper and electrmics in base , plastic housing
questionable life span whole life cost not green at all really.

Lighting aint in a domestic setting a great target fro energy savings.

That depends on the design of the lamp. I have not looked to see
what is available in that sort of lamp, LEDs may not be quite there
yet for a number of reasons including the colour. However, replacing
a 60W lamp with two 1W lamps seems like a no brainer to me.

I'm also not sure why a living room needs "instant" starting. The
lamps I mentioned are fine in that sort of setting in my view.

Useful information, thank you.
What about electricity use over normal life of the bulb?

Halogen should give you at least 2000 Hrs against 1000 of normal
incan, 42W = 60W 70W=100W so roughly around 30%

Turning the temp down on your heating and washing will save
considerably more energy.

Different if you need lighting off grid.

Already done.
