Does anyone know where to buy R63 reflector CFLs that are described as
"100 W equivalent" or actually around 18 to 20 W?

I haven't been able to find anything higher than 11 W ("60 W
equivalent") in R63.

Thanks,
Adam

R63 isn't available as a 100W filament lamp anyway.
To match output of a 100W reflector lamp using folded tube
CFL technology would require a 25-30W CFL, which you won't
find in R63 size.

The only CFL which gives similar output to a 100W filament
flood lamp is the 23W GE Genura. Actually, it exceeds a
100W filament lamp output by around 10%, but it's an R80.
It uses a different technology from standard CFLs and is
unfortunately quite expensive as a result.

I have one in the anglepoise lighting my workbench. Although I'm happy
enough with it I'd dispute it exceeds the visible output of a 100 watt
filament type.

Maybe yours is worn out? Unless they overheat, they almost
never die (not having any electrodes to wear out), they just
dim when they've exceeded their life rating. Also note they
are flood lamps, so the centre beam will be dimmer than a
filament spotlamp because of the wider beam angle.

The first time I used them was to replace a row of 100W
reflector lamps in downlighters down a corridor in an office
block. They were sufficiently brighter than the 100W lamps
that they drew a number of comments from people who hadn't
realised the lighting had been changed and wondered what
had happened.

It shouldn't be - its usage hours ain't that great yet.

The fitting is only ever warm to the touch - one reason for using it.

It replaced a non reflector bulb as an anglepoise has its own.

Perhaps the old bulbs were very dirty?

I'll see if I can dig out a light meter and measure mine.

However I'd not put off anyone using them - they are far closer in
output to what they say on the box than other low energy lamps.

I know. I've got some R63 60W fittings and I'm one of those people
who don't find a "60W equivalent" CFL (for example) to be really
equivalent to a 60W incandescent. I like CFLs otherwise, so I try to
get around it by using a higher "equivalent" rating or upgrading to a
fixture that holds more lamps. (I replaced the single 100W pendant in
my dining room with a ceiling fixture that now has three "60W
equivalent" CFLs; the room is now much better lit for less energy.)

I suspected there might be a technical reason I hadn't been able to
find one.

I'm almost certain an R80 won't fit in the fixtures I have in mind.
Thanks for the information!
