What is energy efficiency?

Doesn't those bulbs consume more than fluorescent types? I mean the first image though...

well anything that consumes less power helps. every little thing helps I guess. just like that water conservation spiel we see around that goes by, "every drop counts."

so yeah I would agree that's being energy efficient.

Is that how many light bulbs you have in your bathroom Cass? Isn't that too many?

Hi Folks - new guy here - Time to jump in!

Initially I started thinking "my gawd!" 6 bulbs producing effective light of 360watts of "regular" bulbs? That is way too much! That is wasteful! That's like joy riding a Prius or smart car two blocks to get the E eco magazine.

But then I started thinking - FIRST ALL, it is none of my business but I can learn from this. I should not intrude my opinion into other peoples' business especially in their bathroom!

Short answer is yes, this is more efficient; of course 14 watts verus previous 40watts is 65% less, longer life, less trips in the prius to get another bulb, less landfill, less heat to discard.... (but a little bit of Mercury...)

But what is the core problem or solution that is being sought? Imho, I should try to balance quality of life along with Energy efficiency and/or reducing Carbon FP.

I don't know the technical term for my human behavior (besides selfishness), but when I walk into a room, and want light, I want full light right NOW, not in 60 seconds or so it takes a CFL to "warm" up. Especially in a Bathroom. That's what bugs me about CFLs; LEDs will fullfill my EE and personal need but I have not done the arithmetic for a payback.

BTW, I do believe in EE, some places I have cfls for outside security lights.

Whew! I just added a bit of CO2 hot air to the mix.

looking forward, tim.,.

Hi Tim,

We are using CFLs. Incandescent light bulps have been phased out. At first I also thought that the CFLs were a sacrifice, but now I enjoy the fact that I save a lot of money in electricity and bring down carbon emissions. It takes actually only about 4-5 seconds to come on, not 60. What bothered me first was that you could not get all the right shapes of bulps. I really like chandelier style fittings and couldn t get attractive fittings at first, but now they are becoming available. By 2012, there will be no incandescent light bulps on sale anymore in the entire EU. My guess is that you guys in the US will follow at some point. By then light technology will have further evolved.
Cheers, techshift

I can tell you the payback you will receive over the life of the new bulbs if you provide me with information like your electricity costs/kw-hr, the life of your bulbs, and how many were replaced.

You will not only save in energy costs, but also in capital costs since you will not need to buy as many CFL bulbs as you would incandescents. Upgrading light bulbs is one of the easiest ways to conserve energy and your electric company might offer incentives since it helps them reduce investments in new power generation.

Energy efficiency is using less energy to provide the same level of energy service. Used office cubicles do same for u as it needs lesser energy and money.

What kind of CFL's are you using to have to wait for them to turn on? My apt is all CFL's and it is instant everytime. Not even a quick flicker then on, just on.

I also have some LED's that I use in film production, and they too are instant. Not only are they instant but dimmable without any change in colour temperature, something regular bulbs couldn't do.

Maybe your bulbs are older, possibly they need to be replaced? No idea but that doesn't sound right.
