I'm already phasing out of CFLs to LEDs the same way I phased out of incadecent to CFL,
one by one as they burn out.  This is because I found out about the mercury/breakage 
problem _after_ I'd almost finished the change over. -_-  Also I've found hauling the old 
CFLs back to the store to drop off in the recycling bin a bit of a pain as I don't like 
keeping the old ones around any longer than I have to, but...don't like polluting if I 
can avoid it...
My original reason for changing away from incadecent was not power cost or environment,
I just wanted brighter light without exceeding the rating of my fixtures.  Hmmm, this socket
is rated for 40W but this CFL bulb puts out as much light as a 60W and only draws 13W.
Problem solved!
So far I've found 2 good types of LED bulbs, everything else is too dim for most applications.
Phillips 60W equivalent (800 lumins) burns 12.5W, standard form factor so it fits everywhere
and is dimmable.  These are made in China:
http://www.homedepot.ca/product/12w-led ... ite/926038I put 2 of these in my living room to try them out after figuring out that the power savings
would cover the cost compared to incadecents over a period of about 2 years.  These were
the last 2 places I _had_ to use incadecents because the previous owner of the house
thought a dimmer in the living room was a good idea and I can't be bothered to remove 
it. ^_-  More recently once I got down to no spare CFLs I bought annother 2 of these to 
replace the CFLs in my laundry room (where due to position there is a higher than average 
risk of breakage) and put the 2 CFLs I took out into my "spare" supply to use up as other
CFLs wear out in low risk of breakage spots.
Sylvania 75W equivalent (900 lumins) burns 18W, kinda big and heavy spotlight, good in
some applications but won't fit a lot of fixtures, even too heavy for some, and spotlight 
style doesn't work in certain applications.  These are "assembled in US from domestic 
and foriegn components":
http://www.rona.ca/shop/~led-bulb-sylva ... a-led_shopI have 2 of these in my bedroom in fixtures with a flexible neck that I have pointed 
near the top of one wall, the reflected light lights up the room well.  I actually have 4 
of these fixtures that I used when dabbling with various lights, this is my test set up 
for comparing bulbs.  (I can turn off one fixture as I'm turning on annother to get a 
side by side comparison of the light.)  The 3rd has a less bright bulb from earlier 
testing and the 4th is off right now.  These 2 bulbs account for most of the light in 
that room though.
As for the not so bright bulbs before I found these 2 types I had bought 3 "Lights of 
America" brand LEDs from Wal-Mart that were all dissapointingly dim, they were all 
close to 30W equivalent.  One is in that 3rd spot in the bedroom I mentioned, one in 
the front porch where I don't need quite as much light, and the other is in my shed 
where it's better than nothing.  Basically the lesson I've learned is you want a lumin 
rating of 800 or more, you can almost ignore what they say it's equivanlent of as 
some manufacturers tend to fudge that number, the lumens is harder to get away 
with fudging because it's a actual specific defined measurement. ^_-
If you really want one of these dim Wal-Mart bulbs and are in Winnipeg don't buy
it from Wal-Mart, I'd be willing to sell you my test bulbs much cheaper than their 
retail. ^_-  But I really don't recommend them.
I'm hoping that somebody gets something in the standard form factor like the Phillips
bulb but equivalent to 100W (apx. 1333 lumens) by the time I run out of spare CFLs.
Then I can get some real brightness in here.  For this reason I'm not stocking up on 
the current models beyond what's in use, don't want too much legacy inventory if/when
100W equivalents become available.  Though I don't want to wait too long because I
suspect at some point LEDs will go through the same cycle as CFLs did where they 
start making crappier ones that don't last as long.  I'm finding I'm replacing my
newer CFLs while older ones are still going.  (Same thing happened with FRS radios,
the first ones worked great then they slowly made them further and further out of
spec. to crank them out cheaper.)
I have a few 40W incadecents left over and a whole bunch of 60W incadecents so if
anyone I know (like my parents) needs them I can supply them for a while.  (Also 
covers me if I can't afford a LED right when needed as they are pricy and I refuse to
shell out for any more CFLs. ^_-)  I haven't had any 100W incadecents in a long 
time because so few fixtures are rated for that much so a few places I have CFLs 
100W equivalents...which need to be replaced with something at some point.
The subsidizing of CFLs (my local utility has really been pushing them) and banning of incadecents is really stupid because it will force a lot of poor people into buying dollar 
store CFLs that will mostly end up in the trash one day because few people can be 
bothered to recycle them.  LEDs are not at a price that is universally accessable and 
CFLs are problem prone in the long run so incadecents still fill an important role.
As for the 90W incadecent bulb, it's been out for a long time from GE:
http://www.galesburgelectric.com/GE-100 ... scent.htmlI remember that line up from GE way back in the early 90s. ^_^
Also CFLs will work at -40 but just won't start up at that temperature very easily, so my
deck light which is left on all the time seems to work fine.
