What kind of screw-in lightbulbs do you use at home?

[Turtle]

Standard incandescent

Flourescent

LED

Flourescent, half the energy, four to five times the life:)

I am converting to flourescent. My house in Colorado was almost completely switched. I am going slower here in Ohio because the cost of the bulbs is higher. And my wife doesn't want them everywhere as they behave differently.

Actually it's closer to 1/4 the energy. For the equivalent light of a standard 100W incandescent, the fluorescent on average uses 29 Watts. I started converting 3 years ago & have lost no screw-in fluorescents to burnout; I have dropped & broken several.

My housemates have voiced similar complaints, such as [whining]"it's not the same color as regular bulbs" [/whining] I slip them in anyway when they aren't looking.:) :hihi: I agree about the cost & my new place is larger with more bulbs so I have put the incandescents in the most seldom used locations.

I am OCD about not wasting & I am so tight with a nickel that I squeek. Reduce your costs, reduce your carbon footprint; install fluorescents or LED lights & turn them OFF when you are not activelly using them.

Waste not, want not.:)

Mainly incandescent, but a few flourescent :)

[Zythryn]

Thank you for the correction Turtle. My mind/memory isn't what it used to be:)

Been using incandesent ones for the decor, and the flourescent ones where I need some real light. Wonderful contraptions, the CFL lamps.

 

LED bulbs?! Where do I get them?!:) I wantit wantit wantit!

Flourescent for me.

 

but LED's would be so cool.

 

Aren't LED lights the closest we've come to replicating the natural lighting from the sun?

If they really care about saving energy.... then why don't they work to make these lightbulbs the cheapest?

 

If LED's and flourescent lightbulbs were cheaper, more people would buy them, and more energy would be saved. but nope.

 

Using energy Efficiancy as a marketing ploy to jack up the prices? Or do they really cost THAT much more to make?

[Tarantism]

in a funny little conspiricy theory that i have heard, the govenments scientists have already developed perpetual energy, and they simply arent giving it to us.

We mainly use incandesent, but flourescent bulbs are prevelent in our basement since we have so many ceiling lights. Also, I think my bathroom and my sister's bathroom use flourescent. All other bathrooms use incandescent as well as lamps and other light fixtures in the family room, living room, library, etc.

Overall, it's a pretty good mix, although we've started using more flourescent than in the past.

The fluorescent bulbs screw-in bulbs have come down in price; when they first came out they were $10 to $12 a bulb & now you can get them 2 for $5. My local Public Utility District distributed coupons to customers for substantial discounts on them last year.

Yes, at this time the LED models cost a lot to make. If production increases expect to see prices on them drop as well.

[Loricybin]

we have incandescent in most every fixture, although we have both in- and flo- in the kitchen.

 

unfortunately we are on a strange, crappy energy source, and the flourescent light has this awful almost nightmare-ish flicker to it.

 

. . . so just incandescent.

[Tormod]

We use both. In my experience the fluorescent bulbs last longer but they have a much more "yellowish" light which is not suitable for me when it's dark outside (ie, half the year where I live).

 

We fixed up our kitchen this spring and installed a new kind of fluorescent tubes (very thin) as well as halogen spotlights (some sort of energy saving kind) and so far we've been very satisfied with it all.

We are now 100% flouro. We have our house and school running from 12 4' flouro’s and 2 18" (2 bathrooms). We blow every bit of saved money and energy on the air conditioner though :)

 

A few years ago, British Columbias energy company (BC Hydro) was doing "tours" teaching about energy conservation and such. at their booths people could pick up a free CPF. 1 per person, they were also handing out coupons at some booths. Ironically not long after the liberal government (which is very right wing in their policies) they have not done anything like it. However BC Hydro is also now partially privatized, probably why. More used more $ made.

 

How far off is 100 Lumens per watt? In an article I have it says a Taiwan company is currently putting it into production. It Taiwan Review if anyone is interested. Here is a link that shows 60 and 70 lumens per watt.

I was looking into LED in Canada and the price is/was pretty outrageous. I haven’t looked into it here in Taiwan but it seems a little cheaper. I now use a tiny LED flashlight to go out in the field doing various reptile/amphibian things. This little light, using 3 AAA batteries, replaces a very large Colman lamp that used one of those big rectangle 9volt things.

 

At a few places here in Taiwan (I think the National University is one) they are working on replacing street lamps with LED's. Currently they are using Mercury vapor and fluorescents. In the magazine article they state they will be installing 100 lumen/watt lamps at the university within the year.

 

 

another link related to the above about LED.

interesting article about OLED and efficiency. There was an article similar to this in Taiwan Review August 2006 about flexible circuit boards and displays.

this short article says Nichia made 113 L/W...

http://www.theinquirer.net/default.aspx?article=29472

 

this article argues the opposite: their main point is testing is not done with reflectors. they say there should be reflectors on the lights (i assume they want a 20 degree beem as they state the LEDS give)

* 32 watt T8 fluorescent--85 to 95 lumens/watt

* standard F40T12 cool white fluorescent--60-65 lumens/watt

* compact fluorescents--low 30's to low 60's lumens per watt, usually 48-60

* T3 tubular halogen--20 lumens/watt

* white LED--15-19 lumens/watt

* standard 100 watt incandescent--17 lumens/watt

* incandescent night light bulb (7w)--6 lumens/watt

* incandescent flashlight bulbs--dismal, less than 6 lumens/watt

Tormod: If you dont like the yellowish, how do you find the ones with higher temperature. 6000/6500(daylight) are nice and blue. Maybe still a little yellow but i like it. Do you happen to know the name of the thin bulbs?
