12/17 Has anyone used a led lightbulb like this? How bright is it compared
to a regular light blub?

\_ That's LED, not led. Anyways, I really don't understand this
fascination with energy saving bulbs. In a typical home,
lighting uses less than 15% of the total electricity. Most
goes to creating/removing heat (AC, frig). What is the point
of spending money on expensive light bulbs that'll only cut
energy cost by 5%?
\_ A 100W equivalent compact fluourescent saves you something like
$30 over the life of the bulb, IIRC. Why would you not want to
do that? They also produce much much less heat, which will save
on cooling costs. Percentages are great, but money is money.

\_ Replacing bulbs in ceilings is a chore?
\_ I don't have cooling problems. I want my place warmer. Would
you think I'd be better off over all using these bulbs and
then turning the heat up more or leaving the heat lower and
keeping my regular bulbs?
\_ Your logic applies in winter, but not in summer.
\_ Do you heat with electric or gas?
\_ Because replacing bulbs in ceilings is a chore?
\_ Cutting back 15% would mean we wouldn't have to drill in ANWR
\_ According to cyberguys' web page, it outputs 32 lumens and is
equivalent only to a 15W incandescent: http://csua.org/u/ecv
\_ Umm, the one at cyberguys's is 18 LED version and the one at
Amazon is 36 LED version from a differernt company, even.
\_ Oops. Wrong one. http://csua.org/u/ecw
55 lumens and 25W (which isn't even double the 18 LED version,
go figure). How do you know it's a different company?
The Amazon page doesn't list the manufacturer; SmartHome is
a retailer, and it looks the same to me.
\_ 25W? I can't even find the floor with 25W. --old n blind
\_ Make sure you are comparing apples to apples ... A
14W fluorescent bulb puts out the same light as a 40W
incandescent ... I imagine LED lights are even more
efficient. |
