Bright future for the compact fluorescent.

A few weeks ago Wal-Mart announced that they would be turning up their marketing efforts to sell more compact fluorescent bulbs. Today, the state of California has announced that they will be doing something similar; they are discussing the possibility of banning the common incandescent light-bulb.  A 15 watt compact fluorescent bulb produces as much light as a 60 watt incandescent bulb.  Compact fluorescent bulbs have a longer life and use less power but the cost per bulb is higher.  The truly energy conscious consumer will bypass the compact fluorescent and switch to LED lights, where you can get a 60 watt equivalent light from an 8 watt bulb!

Yeah, but they suck at "white" light, or anything in the color spectrum you usually want indoors.  If you don't mind things having this odd purple glow about them though....  There is a reason most LEDs you see are colored.

Before I found their 60 watt equivalant bulbs I emailed them and asked which ones were equivalant tothe lights that I am used to... they said "it's wastefull to try to light every corner of your house. Send us a layout of your house and we will design a system for you"...  I wasn't too impressed with that response....

I do want to get some of these LED lights though... last winter we had 20 power outages, many of them lasting for a few days.  I want the 12 volt led lights powered by an old car battery... it'll help save on candles!

I bought a bunch (bunch ==6) of CF bulbs.  Where they say they are "instant on", well, yeah, if they are already on for a while, yes, they come on right away, but if you come home from a day at work they take a minute or so to come up to full brightness.  The color is somewhat different than standard bulbs, but after while you tend not to notice it as much.  

For my own carbon footprint, I probably did better by getting rid of my old 6 cylinder car and getting a new 4 banger that gets better gas millage for my daily commute.  All said, its not so much that I care about conservation as much as I'm a cheap bastard.

Thing is almost all "green" technologies require some sort of investment that makes them seem more expensive at first. The saving comes with time. This applies to light bulbs as well as the way building are, well, built.

So at first at least, when making the initial investment, one can't be cheap.

I have, I think, at least three different types/brands of compact fluorescent bulbs in use at my house. There were comments in the submissions queue about buzzing bulbs, and bulbs that don't turn on immediately, but I've found that those problems are only with certain bulbs. I have some that turn on immediately and are utterly silent.

There is still the issue of warming up to full brightness. The good ones reach full brightness within a few seconds at room temperature, and that's a crucial point. I have a CFL in one of my outdoor fixtures, just outside my back door. In cold temperatures it can take quite a while to reach full brightness - in fact in sub-freezing weather it's light is all but useless for 1-3 minutes and it may take 30 minutes to reach full brightness. I've considered replacing it with an incandescent bulb, but it's a light that I tend to leave on much of the time, so I'll probably leave the CFL for the power savings and put up with the warm-up time.

I'm not at home at the moment, but I'll try to post some brand names later of the good and bad bulbs.

I'm curious about which bulbs you found that don't buzz.  I have the Home Depot ones, the GE ones, and the FEIT ones, and all of them have a very low buzzing sound.  I don't notice it immediately, but after about an hour in the same room, it gives me a headache.  I don't mind the warming up at all, though.  Also, none of them produce the warm light I prefer. They're all rather more purely white.

We have bulbs from mostly Home Depot & Ikea, some old, some newer, and I've never heard any of the bulbs buzzing.  My husband supposes maybe it's an issue with your power?  Otherwise I'm baffled.

Yes, the color temperatures suck, but supposedly they have been improving that lately.  Doesn't help us much, since our older, crappier bulbs won't burn out for another year or so :)

I checked the bulbs; they do make noise, but it's very quiet. So quiet, in fact, that I had to put my ear less than an inch from the bulb to hear it. You'd have to have extraordinary hearing to notice it from more than a few inches away, I think.

These bulbs were from Home Depot, and don't appear to have a brand name. They're marked EDXO-23, for the 23 watt model. They're roughly equivalent to a 75 watt incandescent in terms of light produced, and, yes, the light is very white. They turn on more or less immediately, at least at room temperature, and they reach full brightness within 10-15 seconds.

I've also got some bulbs I bought at Ikea. These were very cheap - like a dollar each, if I recall. (Versus about $3 each for the Home Depot ones.) They make a louder noise and take 1-2 seconds to turn on after you flip the switch. I won't buy these again.

Apparently I'm "blessed" with extraordinary hearing.  Or something.  I'll have to try the Home Depot bulbs.

So far, I've had moderate success with the n:vision bulbs from Home Depot. I've so far only used them in the bathroom and the always on hallways. Upsides: In the bathroom, the "minute to full brightness" is a feature, not a bug. They're quiet.

Neutral: $6 per bulb is expensive, but not hideously so.

Downsides: Quality control isn't the best. Two of the six "soft white" bulbs were identical in brightness and tone to the incandescents they replaced, but the other four appear to have been "hard white" bulbs mispackaged. Also, the twisty inner core makes odd shadows on the top of the outer bulb.

Other upside: they don't get hot, so if you have floor-standing lamps and cats on the back of sofas, they can make friends. One of our cats loves ours and says hello several times each evening.

We have some ikea brand CFLs around the house - they're decent and there really isn't any big delay in them coming on (maybe half a second).  They aren't quite as nice as old school bulbs, but they use so much less electricity that it's hard to justify not using them. To anyone that tried them in the past and didn't like them - I'd second what everyone else is saying and tell you to try them again; they've come a long way.

I don't get the point of outlawing incandescent bulbs.  That is just going to make it a pain in the ass for those of us who either have a legitimate need for the kind of light that an incandescent produces or who just like them and are willing to pay the extra cost of electricity.

If the state really wants to do something they should simply tax electricity.  That should fix the problem.  But they are always trying to cook up some stupid policy that backfires.  For example, the PUC came up with a dumb plan, currently in force, whereby if you reduce your winter natural gas usage by one third versus last year, you get a big rebate.  But they seem to have overlooked the small fact that using less gas is its own rebate: you pay less for the gas!  And those of us who have never been wasteful gas users?  No rebate for us.

Last point: incandescent bulb is only "inefficient" if you need to cool your house.  If your house is heated, they are 100% efficient.

Yes, it is stupid for the state to micromanage all consumer decisions, down to the light bulbs we buy.  If they want to do some social engineering to promote energy conservation, just make the energy more expensive, and let us (the consumers) figure out cost-justified ways of using less.  Taxes might be the way to do that, or maybe there are some subsidies they should get rid of.

Heating via electricity is not nearly as efficient as heating via gas (primarily due to transmission losses I think).  If your house is heated via gas than even that waste heat given off by bulbs is not as efficient as your home furnace.  Also much of the heat given off by bulbs is not directed into the living space (i.e. heat from can lights mostly ends up in your attic/drifting out your roof).

I have a bunch of these at home. My wife's not crazy about them, but she's getting used to it. I think they're great. I have ones that are different "shades" of white. I'm not sure of the technical term, but some are more blue, some are more yellow. In other words, some are more like sunlight and others are more like incandescent bulbs. I use them in differt parts of the apartment. The 'cleanest' one, from Home Depot, I have in the closet. It really helps me see every little piece of crap I have in there. The ones in most of the house are from IKEA, and I don't like those as much, actually.
It makes me feel better to be burning up less watts, and I don't hear any buzzing, and it doesn't bother me to wait 60 seconds for the bulb to get to full brightness.
We do have incandescents in a few fixtures, where there's a dimmer switch. I tend to run these dimmed most of the time anyway, so I'm not likely to change them (can't dim the cfb's)

Now with caps!

Of all the bulbs in my apartment, these compact fluorescent ones make up the majority (3 of 4).  The rest of my lighting fixtures are regular fluorescent lights in unconventional shapes (circular).

Before using the c.f. bulbs I always hated turning on a light and hearing the familiar filament breaking sound and the flash of light before dark.  Mostly I hated it for the fact that I never had a stock of bulbs so I ended up having to switch out bulbs from less used lights until I could get to the store.  It's nice knowing that I will probably not have to change the c.f. bulbs for as long as I'm going to be in the apartment.  Also, the light of the soft/natural style c.f. bulbs are much more soft/natural than the soft/natural, circular fluorescent bulbs.  Thus I tend to use the c.f. bulbs more.
