I also favor the light temperature of the daylight or sunlight CF

very well, although I rarely use direct lighting.. most of my CFLs
are pointed upward for bounce lighting.
The majority of incandescents give off a red light, and I've read
that up to 90% of the output from incancescent lights is in the
infrared region.
**95% ~ 98% is far closer to reality. Halogens are somewhat more efficient.
For folks that experience cold weather for half of
the year, the infrared adds to their comfort.
**So do heat pumps, which are vastly more efficient.
This is easily seen when using film photography as the color levels
aren't natural, but shifted so far that a blue filter is needed to
achieve natural colors.
Only the very early versions of CFLs I purchased were slow to reach
full output.. maybe I've just been lucky, but the ones I use every
day come on quickly.
I strongly suspect that widespread use of LED lighting will have a
much more severe impact on the environment that using incandescents.
The environutz are easily mislead.
**As are you. Provide your proof that LED lighting will have a much more
severe impact on the environment.
I believe that the manufacture of LED lighting will use more energy
and create more pollutants than glass lamps ever did.
**You "believe" it, do you? Got some proof? In your proof, you may consider
the following:
* LEDs use a miniscule amount of silicon.
* Incandescent lamps use a very large amount of silicon
* LEDs can easily last 100 times longer than incandescent lamps.
* LEDs are at least 10 times more efficient than incandescents (and around 5
~ 6 times more efficient than halogens).
The plastics
and various compounds used for component manufacturing will result in
more irreversible air and water contamination.
**Really? Are you trying to suggest that it is impossible to deal with the
pollution caused by the manufacture of semiconductors? Curious.
The extra slap in the face comes with the excessive plastic packaging
the CFLs are usually sold in.
**Huh? You talking about CFLs or LEDs? Either way, the last CFLs and LED
downlights I purchased were packed in recycled cardboard. No plastic in
sight.
.. when old glass lamps were generally
packaged in easily recycled paper products (even as litter, the paper
breaks down to something useful).
**Curiously enough, the last incandescent I purchased (a halogen) was packed
in a cardboard/plastic material. Far less enviroinmentally sensitive than
the LEDs and CFLs I bought.
In addition to increased energy usage, the waste issue of CFLs and LED
lights presents more pollutants than a simple glass lamp ever did.
**Really? What are the waste products you speak of? Have you factored in the
extremely long life of CFLs and LEDs? (I have 19 CFLs in my home, 1
incandescent and a dozen halogens). In six years, I've replaced the
incandescent 2 times (VERY rarely used). I've replaced 10 halogens (rarely
used) and, except for two dropped CFLs, none have been replaced, despite
being used for upwards of 6 hours per day.
The LED lamps aren't going to last for an average of 10 years,
**I'm still using some first generation white LEDs. They're left on 24/7 and
have been for more than 10 years. The latest ones are brighter and should
last much longer.
not
when they'll be manufactured in China/India/etc by the lowest bidder,
and using lead-free solder and the cheapest components available.
The marketing hype and lip service are BS, as they generally always
are.
**YOU have no clue. None whatsoever.
The data is generally never presented in real-world terms, and there
won't be any significant data presented, such as the conversion of
Las Vegas to LED lighting.
The LED lamps that I've seen at stores won't fit in most common
existing lighting fixtures, and have a price of $30-40US. This will
be a huge unnecessary expense to an average homeowner due to a ban on
incandescents.
**More ********. LED lighting is rapidly falling in cost. VERY rapidly
indeed. CFLs were expensive a few years back and now they cost barely more
than incandescents. They last many times longer and use far less energy.
