California Proposes to Ban Incandescent Lightbulbs
zhang1983 writes to tell us CNN is reporting that California Assemblyman Lloyd Levine wants to make his state the first to ban incandescent lightbulbs with the "How Many Legislators Does it Take to Change a Lightbulb Act". The act will promote Compact fluorescent lightbulbs (CFLs) to replace the inefficient incandescent lightbulbs. According to him, "Incandescent lightbulbs were first developed almost 125 years ago, and since that time they have undergone no major modifications, meanwhile, they remain incredibly inefficient, converting only about 5 percent of the energy they receive into light."
What changed under Obama? Nothing Good
If you can see the flicker from a modern fluorescent bulb with electronic ballasts, then you must have super human eyes! It is pretty rare to see new fixtures with magnetic ballasts these days. Those old ballasts certainly had flicker problems. Simply turning one of those old fixtures on would create a lightening effect until the bulb fully came on. If you spun a top under them you could clearly see the rate of flicker. Spinning a top under modern fluorescent (especially multi-bulb) shows only a hint of flicker pattern. If modern bulbs bother you, than a CRT would certainly bother you. I'm assuming that you never used computers or watched TV more than a few years ago before LCD's became popular since the flicker rate would have been worse than modern fluorescent bulbs. If you did, and it didn't bother you much, then I must say that your aversion to fluorescent bulbs may be psychological.
With modern fluorescent bulbs, there is no reason not to use them. They come in warm and daylight temperatures now, so they can more closely reproduce a incandescent light or a daylight look. It is interesting to note that proofing tables (for graphic artists, printers, etc) have fluorescent lights in them. This seems to put weight behind the idea that fluorescents *can* produce good light.
Personally, I bought a 68-watt MicroSun lamp for my main living room to replace the stupid 300-watt Halogen. It's super bright and has a very good color index because it is a Metal Halide bulb.
As far as the law goes.... what happens to the bulb that has been on for 100-years at that firestation in the Bay Area?
It's a wash if and only if you are using resistive electric heating as your home's heat source. Light bulbs (and resistive heaters) have a Coefficient of Performance of roughly 1.0-- a watt of energy makes a watt of heat.
Modern heat pumps have COPs in the 2-4 range for air-coupled units, and higher for water or ground-loop units. A watt of energy pumps 2-4 watts of heat into your house from outside.
And lastly, gas heat doesn't suffer transmission loss to the degree that electricity does, since it is burned on-premises instead of being burned far away, used to make power (at a loss), pumped over transmission lines (at a loss), and *then* made into heat in your house.
I got 6 fancy energy saving light bulbs. They cost $10. The packaging assured me that they would save me a fortune in energy costs and be easier on my eyes.
But they're very fragile, and one of them broke when I tried to arrange my light fixture on it.
And the power here in this building isn't very good, so in relatively short order, two more blew out.
3 of them were in the garbage inside of a month. Wonder how much energy they cost to make?
I got 6 old school bulbs to replace them. They cost a $1. And they last longer.
That's why I personally haven't switched.
Next time I pay $10 for six light bulbs, I want a warranty.
-1 Uncomfortable Truth
I hope the CFL bulbs you bought had handling/disposal instructions on them: CFL bulbs contain mercury. Mercury damn it - mercury! Can you imagine how many of these CFL bulbs break every year, and how many of those weren't handled properly during the cleanup? I wonder how many people are just chucking the CFL bulbs in the garbage (in Brampton, ON, they're supposed to go the community recycling centre, which has a hazardous house waste disposal facility too). I really like that CFL bulbs use little power, but the mercury content is a problem. I'm surprised no one talks about it.
I work for an organization that promotes energy efficiency and we encourage people to replace standard bulbs with CFLs. The new ones are much better in terms of the quality of light, ability to fit inside common fixtures, reduced flicker and noise.
There are, however, still many applications where CFLs just aren't a good choice.
1. There are dimmable CFLs but they only dim so much and not very smoothly
2. Not recommended for enclosed fixtures (trapped heat shortens life of electronics)
3. Not recommended for use with photocells
Another problem with CFLs is that quality is very uneven and people tend to buy the cheap ones. They should avoid CFLs without an Energy Star label.
One good thing about CFLs is that they can produce quite a wide variety of light from a soft warm light to something very close to daylight. People often end up disappointed though because they don't know what to look for and they end up with a light that's too harsh or too dim looking for their tastes.
A ban on incandescents doesn't make sense. You can't really ban them because they are still needed for certain applications. You could however tax them which would make CFLs seem more attractive.
I believe not all CFL's are quite made the same. Instead of looking at what they say they are "equivalent" to, check their Lumen output. Compare that number to your current incandescent lumen output. I have found that "60W rated" CFL's (light wise) have varying lumen outputs between different brands.
I've gotten 60W replacements with lumen outputs higher than the incandescents they replaced and they are indeed brighter (once they fully get going in 15 seconds).
Another thing to look for is the light temperature rating. 'Bright White', 'Soft White' & 'Daylight' are just some of the different light temperature ratings out there. The temperature of the light can give a different feeling of brightness for a particular room. For instance I replace the can bulbs in my kitchen with 65W equivalent CFL bulbs that were Soft White type temperature. They rather sucked. I then replaced those with the same lumen output but with temperature of Bright White, and the results were much better for that type of room.
Things to think about for sure.
I recommend the CFLs from Ikea - they are rated at 6W - and claim equality to the output of a 50W incandescent. They have a globe around them to look like traditional bulbs, and except for the color of light they cast, I was quite impressed with the quality and brightness- it was greater than many cheap ones I have around. They are about $3.50 each, but last forever under the right conditions in my place. The only thing is that they don't fit in some fixtures I have.
Most importantly, though, I noticed a drop in my bill immediately - greater than the cost of the 4 bulbs in one month.
Dammit Otto, you have lupus.

So, if you add the 4mg intrinsic to the CFL(being pessimistic here and assuming NONE get recycled properly) and the 2.4 mg from electricity production you end up with 6.4 mg of mercury released to the environment, as opposed to the 10 mg for regular incandescent bulbs. About 2/3 the mercury our regular light bulbs are giving off, and some of the CFLs will get recycled eh? Sounds like a good tradeoff to me.
It depends on how you perceive light. An incandescent has a constant stream of photons whereas a fluorescent has spikes as the arc passes through the tube. Some fluorescents when new are 60Hz, some 120Hz, some ~10kHz. So depending on the density of rods vs cones in your eye and other genetic variants in their response time, and the way your brain interprets that data people can perceive far different quality of light coming from a fluorescent.
Some people see 60Hz fluorescent light as a solid white where others see it as a really fast strobe light. Also, as fluorescents age they start 'missing' and have a lower and intermittent Hz.
Like color blindness, if you don't have 'fast' eyes it is hard to believe that the bad fluorescents can make others physically ill when all you see is solid white.
The dangerous stroboscopic effect only occurs if the fluorescent light source is using a magnetic ballast, which drives the light output to oscillate at the same frequency as the alternating current (60Hz in the USA). Electronic ballasts increase the oscillation frequency to something above 20000Hz, eliminating flicker and increasing energy-efficiency at the same time. Magnetic ballasts have been outlawed in commercial and residential applications, but are still allowed in some cheap "shop light" fixtures meant for garages and such, so watch out.
Be aware that LEDs operated on AC exhibit worse flicker than the cheapest fluorescent. At least with a fluorescent, there is some light from the phosphors between cycles -- an LED goes completely dark between cycles. I recently examined dozens of brands of LED holiday lights -- every single one flickered like crazy. At least they made some cool effects when you swung them around.
Tips & tricks:
1) CFLs don't typically work well on a dimmer switch or any faulty wiring. I've found two instances of faulty wiring in my home because of constantly blowing CFLs.
2) In Washington State, many companies (Lowes, Fred Meyer) have coupons for $2 off a CFL, up to 8 per person per trip. Albertson's, Lowes, Fred Meyer, Wal-Mart, etc. sometimes have sales with bulbs running about $2 each - free light bulbs! Stock up as you only have to pay the tax on them - comes out to aobut 18 per bulb depending on local tax rates. 3) The CFL coupons are available through various electric companies nationwide - not all areas have them. 4) CFLs contain a starter just like any fluorescent bulb. This is what makes them wear out when used with a dimmer. 5) Be careful about using CFLs near infants and children. The mercury CAN cause significant health issues. CFL, dimmer at night for the night light - can add to the mercury content for a child if the light blows up.
This is the problem with having legislators rule us. They don't always check the facts or dangers but require us to obey.
With electric rates being Federally deregulated in 2008, CFLs help NOW, but when consumption drops, then the electric companies can charge just a little more for less power. Seems like a good idea until you realize you pay just as much for 1/4 the consumption. Ingenious way of raising electric rates.
