I would like to replace my kitchen under cabinet 20 Watt halogen puck lights with something that is more energy efficient, uses less electricity, runs cooler and produces brighter, more even lighting. Any ideas?
The old light bulbs — which were round and used 60 to 100 watts are being phased out in Canada –(I forget which year they will no longer be available for purchase)
As a result the old light bulbs are on sale everywhere
Ontario Hydro , top scientist David Suzuki and so on are advocating for the new energy efficient light bulbs
Suzuki has been putting the message into a Canadian format and spreading it
"Less electricity equals more beer"
The say you can save about 45 dollars a year per light bulb — so I thought make that 36 dollars a year or 3 dollar a month times 10 light bulbs –30 dollars a month or 360 per year
I have been buying them with the idea that I will save money on my next hydro bill ( more money for beer) and that I am doing something good to reduce power consumption
———– Here is the only draw back to using them I have found — there can be up to a 5 second delay when turning them on to lighting the room — other than that it appears brighter than the regular bulbs for slightly less than 1/4 of the electricity 13 watts compared to 60
Has any of this all of this or some of this het the US yet ?
This bulb —
I like Sukuki’s message better – but the above link is far more informative
Solar Motion Light – If You’re Considering To Go Green And Save Electricity
The motion light is the new technology the place the light glows when it detects some type of motion and off late they’ve been more and more becoming your best option for porch lights by house as a method of security. There was time when porch lights have been required to be illuminated throughout the night to keep away burglars or intruders in your house. As a result of evil forces all the time hate late and so they additionally don’t love to do the crime beneath light. But the rising electric cost and the conscience over environmental factors have compelled folks to thought about motion sensor porch lights. They’re made of contemporary technology and the illuminate solely once they sense some motion of an intruder thus saving almost 60% of the electrical energy which basic porch lights had been supports to consume. To save further electricity and billing, you can opt for solar motion light.
The solar motion lights are the lights that run on the solar power. The solar energy converts the solar power to electrical vitality and thus gives the electrical energy required to glow the lights. Whether or not they are for porch lights or yard light or every other areas, they are good choices for all purposes. All it’s important to do is that find the right high quality of solar lights for the purpose. The solar possibility for lights, are little costly but it is one time investment for long years. Most sun cells include warranty of 10+ years and have lifespan of minimal 50 years. Thus you can imagine the way you’ll be saving the electric payments and likewise the environment.
If you’re pondering to go green and save electricity then there could be no other method than putting in the solar motion light at your property wherever they are requires. Even the motion lights are good for interiors as a result of they would illuminate only when there’s presence of someone in the room. Mostly it happens that we hold the lights illuminated for long hours without caring the electrical energy consumption and pressure we placed on mom earth. The lights would mechanically glow the moment one enter the room and can lit, until you are there. When you come out it can minimize off robotically after few moments.
And above all the solar motion light makes one of the best porch light. The aim of mounting porch lights is to thwart intruders to your house. In an effort to result in this safety gauge we are likely to hold the porch light on throughout the night. But with solar lights now there isn’t any worry of switching on the lights and getting up at daybreak to change off the lights. The one resolution is simply installing the solar motion sensor porch light. Such light just isn’t solely protecting but additionally economic.
The solar light with motion sensor is thus the perfect funding you may make in your house for safety, electrical energy saving and scale back the cost of expenses. They’re long term investment which could be very much fruitful and you’ll be actually happy with such installation.

Hi, I refer to http://answers.yahoo.com/question/index?qid=20080424180503AAXVFzE
The above is a question of only 1 bulb. For me, all my energy efficient bulbs flicker with a tinge of light even powered off. This is noticeable only when there is sufficient darkness around a particular bulb. Not noticeable during day time.
If I turn off one circuit (from my mains circuit breaker), then the flicker goes off in the bulbs for that circuit.
However, other type of lights eg. even energy efficient fluroscent tube lights do not flicker when off.
Could it be all the switches are leaking electricity ? I’ve just rewired my house over 4 months ago. Hopefully I did not get cheated by the electricians 
Is this a fire hazard ? Since all energy efficient bulbs do this.
Ok here is the scenerio. I have outdoor christmas lights hooked up to a outdoor cord. My house does not have a outdoor outlet so I have an adapter hooking the outdoor to the indoor then through the front door and plugging it into the living room leaving the indoor plug subjectable to the elements. I solved that by wrapping a paper bag over that part. I feel deep down that I am being stupid but Im not one to trust my instincts and I know squat about electricity. Not looking for a lesson more of the percentage of death and destruction.
what is the formula for calculating how efficient energy is? also,
1.a clothes dryer has a power rating of 4356W. It takes an acerage of 45 min to dry a load of clothes, If the dryer used 8820 KJ of energy during this time, how efficient is this dryer?
2.if a 60W light bubl in a lamp is only 20% efficientin converting electricial energy in to light energy, how many joules of light energy does this light bulb produceeach minute?
3.The heating element in a ketel has a resistance of 10 ohms pluged into a 110V outlet. When heating water, only 75% of energy produced is actually asorbed by hte water. How much heat energy does the water absorb if it takes 4 minutes to boil?
4a. how much energy will 100W light bubl convert to light if it on for 1 hour?
4b.If bulb is 15% efficient @ converting electricity in2 light, how must energy has been lost to heat?
full solutions/ explainations please.
This is part of my physics project. Need to build a model. Lets just say you are at some forest with no lake or anything and you have to generate enough electricity to light up an LED, how would you do it?
Thanks guys. Really need some ideas. Been thinking for days.
you can assume that you’re in some small village.
I know scientists have managed to find a way to make dark matter particles, but can we alter a normal particles’ gravitrons causing it to become lighter or heavier??
Was thinking about this because some things act very strangly when electricity is run through them, at a medial voltage, but I was wondering what has been tried with extremely low voltages.
I mentioned the part about electricity, as particles are held together by Nuetrons and protons. There are effects from shooting in a songle proton, or nuetron….
but what about altering the electrical attraction?
I know that solar panels get there energy from the sun, but is it just from its heat? Many other things give off heat, like a heat lamp. I put a solar powered light i found up to a heat lamp for a minute and it had energy to produce light for a long time. I don’t know what else it could be, just want to know for sure.
Thanks in advance.
Oh — well in this case I’m talking about solar panels that produce electricity.
1. All transportation vehicles must be hybrid.
2. There must a minimum of 3 trees near where you’re living (The building.).
3. All light bulbs must be fluorescent and citizens may not buy or sell regular light bulbs.
4. No smoking of anything, especially if it causes smoke, is allowed.
5. All electricity must be created by renewable resources, such as solar, wind, tidal, hydroelectric, or geothermal energy.
6. Fossil fuels – coal, oil, and natural gas – uranium and any other nonrenewable resources may never be dug up or used.
7. All parks must be at least 4 square miles large.
8. There must be a minimum of 10 trees at every park.
9. The maximum amount of water used in the bathroom is 50 gallons per person.
10. All faucets and showerheads must be low-flow aerators. All washing machines must also be a water efficient model and all toilets must be high-efficiency toilets.
11. Littering is not allowed anywhere in this city.
12. All recyclable trash must be recycle.
I just need a couple ideas like the one’s I just listed. I need 8 more, but you can list less. if you see something wrong with the one’s that are listed like if they aren’t related to using/wasting energy or conserving energy. Tell me! Thanks!
Serious answers please. One’s that aren’t absurd, that make sense, and real people who live in cities will actually do.
People look!!! This is just a little thing I need done. I’m just a kid who wants a little tips. I’m not gonna try to kill people!!!?? What’s wrong with you? Seriously….
