Just for accuracy's sake:


I think you meant florescent because the "common" light bulb is incandescent and they do work on dimmers.


Cheers.

And there are CFLs (compact fluorescents) that do work on dimmers, though I haven't looked hard since I'm no fan of dimmers myself!

There are currently two brands that produce a dimmer-capable  CFL


http://www.taunton.com/finehomebuilding/how-to/qa/compact-fluorescents-bulbs-dimmers.aspx?nterms=657
58


Phillips now makes a CFL with only 25% of the mercury content of the cheapest and most common CFL's (I've heard that "mercury-free" bulbs are coming soon, due to demand.


http://www.greenerbuildings.com/news_detail.cfm?NewsID=34914


Some bulbs now come with a shatter-resistant plastic cover. Commonly found in outdoor applications they are referred to as "capsule CFL's". They could easily be used in a childs room.

It is ironic that common sense flies out the window when the matter of CFL's come up.  (This one is lengthy as I do hit some volumes of detail.  The most important paragraphs are the last 5 paragraphs.)


As a replacement for incandescent lighting- sure, BUT Most of the US has a heating season.  What that means is there will be a net zero change in energy consumption in the long run- that heat entering the domicile via incandescent lighting means less heat the heating plant has to produce.  Remove those incandescents for energy efficient bulbs- people will see the savings on their electric bill unless they have electric heat.  Everyone else will likely use as much other energy form used for heat as those light bulbs produced.  For some- not an issue.  But then comes disposal.


If people are truly concerned about environmental impacts, make the switch now to LED lighting- no mercury.)  CFL's would not ever come up again as an option if their EOL impacts were considered first.  This change for LED lighting has only really come about within the last 6 months.  LEDs are the future, and one industrial supplier has broken the light output barrier if you want to call it that.  In one case, a thousand Lumens from a single die, and a Power LED Xlamp capable of 100+ lumens output from one Watt input.


Drop a CFL- what happens?  Granted, mercury is bad- it is the only metal with a vapor pressure, and oxidizes so readily that an oxide layer forms on amounts that can exist as a nodule.  A teaspoon of mercury if not oxidized, could a lecture hall full of people within an hour otherwise.  The amounts used in florescents is so miniscule it vaporizesand oxidizes the moment the envelope breaks.  But that mercury vapor released, while not immediately a problem, does add up in the atmosphere and can precipitate out in rain.  So why contribute to that amount by buying CFL's?  They may be reasonably cheap now- but end of life?  How about light output after a month or two?  In some cases, there is a noticable amount of loss.


Drop an LED array, it may crack in some designs, or it may bounce in others.  Is there any contamination?  Nope.  Then there is the matter of End Of Life?  50,000 to 100,000 hours later- work it out.  That would be a decade from now or longer if left on all day and night, and with even less energy consumed.


Consider in your home- how much storage space do you dedicate to storing your items that reached their EOL?  Then consider a 5 Watt Power LED is about the diameter of a US quarter, and maybe 1/4 inch thick.  This means more room in your closet for EOL items.  Then consider what impact on storage space occurs in an office or institutional environment of 100,000 square feet?  


While the technology still has a ways to go- it is at a useful stage now for true consideration and CFL's lose horribly in this discussion.  Compare 50,000 hours of an LED to the life expectancy of a CFL- the CFL loses at a mere 6000 to 8000 hours.  Then figure time required to replace each one times ten- Now figure Union Scale on that too.  


Dimmability is easier with LEDs too.  CFL's and all florescent tubes can be dimmed via "Pulsed Width Modulation."  In the case of the cited CFL's above- they utilize this technique, and it is resident in the control chip on the circuit board in the base.   A number of manufacturers of that chip use the PWM method for dimming.  (It is also used for stepping up the voltage in cell phones to drive the LED flash module in cell phones.  It is also the fundamental principle for switchmode powersupplies.)


LEDs can be dimmed with PWM, it is less energy consuming than linear regulators or rheostats, therefore more efficient.  Isn't that the real goal?


CFL's are not an answer- just a transitional technology.  Transformer supplies for LED lighting on 120VAC kills the energy savings potential that exists dropping them to the same level as a 2 tube trougher.  The solution I am using in my transition is to supply from a surplus switchmode supply from a computer printer, or other device.


But with all this said about the alternatives- what really happens is the incandescent light bulb will now be the target of social engineering taxation.  All for show, as it is largely going to be a zero sum discussion about the incandescents "wasteful nature."  If you heat with alternative energy already- it is not that big of a deal.

48-volt LED link
« Reply #39 on: March 08, 2008, 10:42:49 PM »
Hope this isn't too much of a thread drift, but...


The electric bicycle forums are very interested in getting as much LED light as possible from as few Watts as possible when riding at night. 48-volts is a common battery value there. Here's just one discussion of many, use the search function at the top right for more if this type of discussion is valuable to your project.

My prius has close to 60,000 miles on it and hasn't had a single problem... haven't even changed brakes on it yet.  According to them, I'll be disposing of it in 49,000 miles from now lol.

 This is a great post and you are right. Most of the time the gain from installing a CFL is Zero, but there are some advantages. An incandescent light bulb is really a heater that gives off light, not a light that gives off heat. In either case it is 100% efficient. It depends on what you want. Heat or light. In the winter time for instance a CFL would be better used on the exterior of the house where most of the energy consumed is transferred into light, not heat. In summer when your a/c is running a CFL would add less heat gain to the home than an incandescent bulb. In winter it makes no difference, as you stated.

I'm sorry but it is not true unless (a) you heat your house by electric resistance heating rather than any of the more efficient/cheap alternatives such as natural gas, wood, heat-pump, etc, etc, and (b) you really really want to heat the space above the bulb rather than, for example, near your feet.


As an example, in the UK, per kWh of heat, natural gas is about 3 or 4 times cheaper than electrical resistance heating, never mind about half the CO2 emissions (190g vs 430g typically), so heating by light bulb is many many times less effective and more environmentally destructive than the most common (natural gas) alternative.


Plus gas central heating puts the heat nearer the ground where it's needed and delivers that heat better.


Other then for very specialised applications such as incubators and some hot foot displays for example, if you want light get an efficient light sources such as CFL or LED; if you want a heat source, get an efficient heat source such as natural gas or a heat-pump.  Don't use an incandescent light bulb which is neither.

That discounts normal air movements throughout a room from convective heating or cooling from windows, other appliances and fans.  


All in all, there is no real net energy saving from using CFL's over regular incandescant bulbs, especially if you factor in the specialized nature of the waste handling at EOL or the extra energy required to produce them- which you do pay for up front.  EOL energies are over and above that.

To drift a bit further, the choice for 48 volts for those electric scooters is to keep the current draw down to managable levels for the gauge of wire they aree using.  Essentially all that was done to achieve the 48 volt power LED modules was to add a resistor into the circuit.  The same basic idea when you see the LED C-7 candelabra light replacements.

HD;


Yeah, I still see / hear folks regurgitate that old propoganda how solar panels take more energy to make than they ever make, too.


I think it is a persons duty to question statements that are just, uh, not, well, true!


Its not what someone knows that worries me. Its what they know that just ain't so that worries me, personally. A plethora of posts from Skip lately many with the same type of dodgy statements. So far I have been hands off until you decided to pipe in.


Just an opinion.

You can also roll you rown dimmer- all you need to do is adapt a PWM circuit to your light switch.


Seriously though, due to the nature of the CFL's ballast circuitry, in theory any of them are dimable, and according to Zetex, who is one of the manufacturers of the Ballast controller chip for CFL's, they "theoretically" can operate at 30 volts, or possibly below.  But some controller chips are better suited to convetional diming circuitry.


But remember, theoretically, a Bumble Bee and a Frisbee are not able to fly by US Air Force standards of long ago, and theoretically; Detroit was to have been producing 70MPG commuter cars by 1990.

Ya takes yer chances.


Personally, I can't wait for the LED pricing to drop enough for inexpensive Edison Mazda retrofits.  I hate CFL's.

Actually, physics and thermodynamics ARE on my side when you are not in the "sun belt" of the US.  Areas North of that region usually operate a heat plant of some sort- many times electric heat no less, for 8 months (or more) out of the year.  When you are IN the sun belt, or outback of Australia, then, yes, there is a net overall saving of energy, but the reality is still largely a matter of where you live that determines the viability of the argument of just how "green" a CFL is.


Now, should you drop a CFL, and you want to abide to all sanitation laws- your cost savings you "might" have realized, now no longer exit.  Plus all the materials you have now added to the waste stream that would not have been there if you had merely dropped an incandescent bulb.  


Regardless of how you slice it you may be saving some energy in one area, you have to make up for it in another when you are discussing matters of heat within a home in the region of the US where you are not in the sun belt. That is what we are discussing, commercial buildings are a whole different animal due to the wide illumination requirements, even when no one is in the vicinity.  


Where you live makes the largest difference.  If you want to disagree- and be taken seriously about it- produce ALL of the numbers, complete with the breakdowns of the costs forconstruction and disposal including handling and transportation costs and hazardous materials permitting and disassembly and ultimate disposal on a per unit basis.


Until you do that, all you have to back up the assertion of me being wrong is just "happy thoughts" and 'wishful thinking' with no supporting documentation of real costs.  The same thing driving the mistaken notion of an ethanol based economy.  You won't see it until the US is fully on board with the Carbon Taxation plans being rolled out.


Regardless- until you remove the mercury completely from a CFL, the extra handling still counts against them.  Their higher initial cost counts against them too.  People don't want to factor those two details into the equation because it is still a losing proposition for them when the truth is factored into the discussion about their special handling required for disposal of CFL's.  


By compairison, if you do not factor in the costs of inspections of a nuclear plant, or the disposal costs of the waste, you end up with a favorable economic argument favoring a nuclear power plant as a cost effective project- but as you factor those 2 important details into the construction and operation of a nuclear reactor, the costs of the disposal alone cut into the notion of cost effectiveness tremendously.  And if you should drop one and it breaks?......


And regarding the old arguments about solar panels cost effectiveness date back to a time when Gemini was the hotest vehicle out of Cape Canaveral, Florida.  


Times change.  Technology changes too.  Thermodynamics does not.

Again I have to disagree strongly with your claim "in theory any of them are dimable".


Trying to dim some CFLs could easily cause a fire given the diversity of circuits out there.


Yours is an unsafe speculation that could get someone hurt and has no basis in fact given that you cannot possibly know all the CFL ballast designs in use worldwide, never mind the fact that not all CFLs work on 110V 60Hz.  (What about my 12V DC CFL for example: wire that to 30V and it will almost certainly catch fire.)

PS. Plus, AFAIK, many dimmers are NOT any old PWM but rather zero-crossing phase delayed synchronous PWM for various reasons including RFI minimisation and ease of implementation with triacs.

Try the fairly full analysis of lifecycle costs in the book at http://www.withouthotair.com/ IIRC, just for one.  And then the exhaustive studies by the UK's "Market Transformation Programme" (part of DTI/BERR), the Carbon Trust and the Energy Saving Trust, plus their various EU counterparts.  If you really insist I can supply you with links but I don't have much hope that you'll read the research behind them.  It's astoundingly clear that for VIRTUALLY ALL domestic users EVERYWHERE not wasting 97% of the hard-to-generate domestic electricity as heat is a plus, ESPECIALLY where generating that electricity is from fossil fuels and additionally where that FF combustion releases mercury.  (Commercial users already understand the numbers by-and-large.)


This applies from Kenya to Finland with essentially no commonplace exceptions for Joe Sixpack.


Local heating/cooling conditions are relatively unimportant since even in a climate where heating is necessary you SHOULD NOT be using electrical resistance heating, but at the very least something like a heat pump.  So heating with a light bulb is almost NEVER the right thing to do.


Your last two statements at FF suggest that you need to get your technology understanding up to date rather than tilting at windmills and issuing misleading and in some cases dangerous assertions.

Without the Hot Air deals with the finances rather than the energy, see:


http://www.inference.phy.cam.ac.uk/withouthotair/c9/page_58.shtml


but I assert that they are closely correlated.


I just had email confirmation from Prof MacKay that he views a potential weakness of his analysis to be that "the curve relies on the CFL asserted lifetime, which some say is exaggerated" but I suggest again not enough to make a material difference.


And in any case this is all a sideshow until LEDs take over of course.


And note that I can as easily drop an incandescent to prematurely end its life as a CFL.

No- you need to understand the original post I posted as well as the influence of politics, political powerbrokering and money motivations behind such matters.  


For one- look at the "global warming" issue, you can get all sorts of grant money to research for things that "support" the notion of global warming being caused by man.  You will not find much money, and certainly none from the UN or any of it's NGO's to further the notion that what is pointed at as evidence of global warming is actually just a natural cycle, or naturally ocurring phenomena that man had little or no influence on.


Regardless of one's position on that matter, there is a lot of seed money out there to protmote the suggestion there is impact by man, the actual fact of it existing or not is not worth debating here because I am using that as a demonstration of the framework of manipulation.  


Sure, there are all manner of graphs to "support manmade global" but not one of them is an accurate representation because the "evidence" of the graph data is manipulated to support the conclusion, not to be independant of it.  Which is why you ofte the overlay of population in billions scaled in a way to show a steep increase, and the carbon dioxide graph, which is addressing a change from .04% to .05% (the decimal point takes it from parts per 100 to parts per 10,000)


You see the graphs showing significant slope upward, yet, the difference when one looks at the scaling is less than .01%.


Then there is the "Piltdown Man."  There were many books written on the subject and not one of them being dissent.


But I direct you back up in the thread- where it is mentioned the incandescent light bulb happens to be a heater that produces useful light.  It does.  No argument.  I live in an area where there is heating requirements for the better part of a year.  there is therefore a heat gain factor in lighting with incandescant lights.  Once you remove that heat gain, you have to replace it. The argument of it being valid for those heating with electricity only is specious at best.  SO there is omething magic about LP heated air that makes it different from electrically heated air, which makes it different from air heated by wood, etc?  


Fact is, if you remove the heat source of incandescant lighting from the home, you have to make up for it somehow in order to maintain the same room temperature.  You are therefore increasing the load- now matter how big or small, on the homes heat plant.  The net gain is truly zero.  


How much difference one sees is going to vary because we all use electricity differently.  The net result, no matter how many happy feeling book titles you present, remains that the net impact is at best zero.  But to ban incandescant lighting as Australia has, and other countries, is only political posturing by the politicians.  Most people actually are likely to use more electricity as a result of CFL's, a side issue, but for many of the reasons cited to above in several posts.  


Show me the links to the raw data.  I will make my own decision.  Books just represent one author's filtering based on political and monetary influences.


You still have to factor in the matter of the costs for the specialized handling cost.  I can tell you 11 million dollars (US) is added every week to New York City's waste collection services (not including equipment and infrastructure costs or amortizition costs of wear and tear) because they do not single stream their waste handling.  That 11 Million dollars number is based on the year of their trash haulers strike several years ago.  


People never want to talk honestly about the costs involved in recycling.  This is where the percieved benefit of CFL conversion fails.  Picture 1 million people in the US each year making a special trip in their car to dispose of 1 CFL.  This turns the carbon equation on it's ear.  And this happens, I have worked at regional recycle events, and I know the waste handling costs are considerable.  I also read numerous trade magazines on various aspects of the subject of recycling, waaste, biofuels, and others.  


But NO WHERE am I saying nor have I said there is no benefit in the US sunbelt, Australia, or elsewhere.  Read my post and understand it.  In those areas where the heat plant is not in use for much of the year, and cooling systems are employed, in those areas, there is no question of benefit because it reduces the amount of heat needing to be removed from the home- but the better solution is LED lighting.


Understand the original post before you pose and posture.  Post your cost graph links because I want to see them and make my own decision because statistics can be manipulated and most are when the UN and money are involved.  Few understand the bigger threat is actually Hydrogen Sulphide- not carbon or it's compounds.

The cost of use diagram only reveals the retail pricing of one over the other and then assumes quite a lot in between.


Because of the political pressures, I am seeing in retail stores bulk pricing of incandescents.  That throws such usage graphs off kilter and really makes them irrelevent.


I have purchased very few incandescent lights "new"  In fact, I have actually purchased more low voltage light bulbs new than any other type.


The claim of 12,000 hours is false.  The typical florecent fixtures usind in commercial applications, has a ballast life of about 6000 to 12000 hours, and there IS a 12000 hour rating on the components of the CFL Ballast.  I suspect someone omitted that detail because they "mean well."  The florescent tubes are typically rated between 2000 and 4000 hours average expected lifetime.  I have a fair amount of these.  The only tubes I ever purchased new were for the plant lights.  They are servicable items, I do not see any remanufactured CFL's being offered in the US.    


Also, knowing what comprises the CFL ballast, I am not impressed at all of claims at how "economical they may be.  No question they have uses, but to legislate them in the US would be folly and a waste of time, but the political "hay" that could be made from such posturing would unquestionably be enormous.  A politician could then claim "they made a difference...", "they actually did something...."  When you understand the technologies you also begin to see the political bandstanding for what it is.  


The disposal costs and deconstruction costs of CFL's still outweigh the asserted economic benefits.  Ultimately- when all costs are factored in, no significant economic benefit to a homeowner is achieved by changing wholesale to CFL's unless they live in an area where the cooling need is a significant part of the year. That homeowner as a consumer will ultimately see all of the taxes, the costs of the regulatory burden, and general costs and soon carbon taxes factored in when they pay for the CFL, or to lawfully dispose of the CFL. And it is instantly a losing proposition in the event they lawfully report their broken CFL's and clean the area up as per the HAZ-MAT warnings based on the contents of the CFL. Never mind the fact the tiny amount of mercury used has oxidized on contact with the atmosphere.  Fortunately Mercury has a vapor pressure.


LEDs are the future- but where you gain in energy saving in illumination usage, you still have to make up for in areas where the heat plant of a home is in use for the greater part of a year.  Which has been the fundamental detail I pointed out at the very begining post.

Go ahead and disagree, because I stated "theoretically"  Or did you decide to ignore that part out of pomposity?


I did also state there are some CFL ballast controller IC's in use that are more adaptable to dimmers than others.


Maybe you need to spend more time looking at manufacturer spec sheets than trying to pose and posture pompously because you misunderstood the intent and verbage of the post.


Unlike yourself, I have done the research to find better low voltage lighting options that utillize off the shelf standard items, at a low cost.  I focused on stand T-8 and T-12 tubes as a starting point, and research brought me to many manufacturers data sheets, which are a wealth of information.  You should read some sometime.
