Hi John,

I was discussing the relative size of CFLs in another thread and I've
copied part of our discussion here in the hope it may assist you.

Cheers,
Paul

GE makes this claim with their T2 line and it holds true, well, at
least in part. Their 10-watt spiral (40-watt equivalent) is just 3.7
inches long and their 13-watt spiral (60-watt equivalent) is 3.9
inches. By comparison, a standard 40-watt or 60-watt A19 incandescent
bulb is approximately 4.4 inches in length (4 and 7/16 inches to be
precise).

As we move up in wattage, things start to unravel somewhat. Their
20-watt and 23-watt spirals (90 and 100-watt equivalent) are 4.8 and
5.1 inches long respectively. Their largest mini spiral (29-watts/
150-watt equivalent) is 6 inches long, whereas a standard 150-watt A21
incandescent is just a little over 5.3 inches. Be that as it may, any
table lamp with a standard size harp would accommodate any of these
bulbs and certainly the 10 and 13-watt spirals should fit a fixture
that takes a regular household incandescent.

For anyone looking for a 150-watt replacement that is no larger in
physical size, Osram Sylvania's CF40EL/Twist produces 2,600 lumens and
is 5.25 long. It is the same width as a 150-watt incandescent and, in
this case, just slightly shorter.

I'm fortunate the two Home Depot stores closest to me carry a good
selection of Philips products, including dimmable and three-way CFLs.
I know they stock the candle shaped CFLs but I'm unsure as to their
wattages. If you are having trouble finding any of these products,
there may be hope yet. Most local electrical/lighting distributors
have a "cash and carry" counter where you can purchase items not
normally stocked by the retail chains; so long as you have a product
code or product description (easily obtained from the manufacturer's
website) you shouldn't have a problem.

I have become a true believer in the Compact Fluorescent (CF) lamps than
replace "Edison base" standard lamps.

The problem is that ceiling fan light of the "schoolhouse" type (round
globe) will not accept any but the smallest CF.

A 10" diameter globe would only take a 15 watt CF. In theory that's as
bright as a 60 watt conventional light but who is kidding!

In a rental property, we have two fans with small globes (8"?). The only
CF that would fit was only 5 watts. The same fixtures could take (and I
installed) 60 watt incandescent bulbs. I would MUCH rather use a CF. I
would need a CF that doesn't exceed about 3.5" in any dimension but that
puts out more 15 watts of CF light. That's not much but it's better than a
5 watt light.
