How to - get a better color/Light from CFL bulbs
With Incandescents being "outlawed" many people will need to buy & install CFL's
Seems many people are dissappointed by the color/light output of CFLs This thread is a discussion, explanation of the color/lighting available 1st CFL's come in different wattages - & list the equivelent incandescent wattage Normal wattages are - these vary slightly by Mfg: CFL 9w .........= 40w equiv 12/13w....= 60w equiv 14/15w....= 75w equiv 22/23w....= 100w equiv 65w........= 500w equiv (floodlight) There are smaller wattages, but they tend to be more expensive CFLs DO contain Mercury - same as every flourescent light in almost every workplace for decades The overall mercury put into the environment is LESS due to the fact they use less energy That means less energy needs to be produced, as a result less mercury is released into the environment in creation of electricity http://www.energystar.gov/index.cfm?...r_cfls_mercury Incandescents produce only 10% light & the rest of the energy used is heat CFL's produce the opposite, only 10% heat If you have a recessed can or other fixture that blinks on/off with an incandescent then try a CFL Recessed cans have a thermal sensor, if it gets too hot it shuts the light off CFL's come in many different types, the curly bulbs are the most widely known But they also come in a reg glass bulb enclosing the CFL within These are great for the lamps where the shade is "attached" to the bulb http://www.eartheasy.com/lighting_bulbs.jpg Yes - this is a CFL bulb too: http://www.crunchgear.com/wp-content...ightbulb01.jpg CFL's come in different light "colors" - Kelvin rating = K Please note the K ratings will change by Mfg & Mfg can change these at times Also note that many bulbs will NOT list the K rating on the bulb - only the pkg Lots of times I will use a marker & write the date of installation on the bulb base In some cases I also write the K color on the base Normal green pak from HD Nvision Mfg = soft white = 2700K Red package from HD Nvision Mfg = Bright white = (4500k ? - guessing) Blue pak from HD Nvision Mfg = Day light = 5500K Blue pak from Lowes Bright Effects Mfg = Day light = 6500k http://www.freestylephoto.biz/images...rtempchart.jpg http://www.bltdirect.com/images/colour-temperature.jpg http://www.energystar.gov/ia/product...emperature.jpg That's it for now -Dave |
Just for people's information, the October 2009 Consumer Reports has ratings and rankings on CFL bulbs by brand. (Not sure if this data is accessible on their website to non-subscribers.) Generally speaking, EcoSmart, GE and Philips come out tops. I found it a useful article because it's certainly been my experience that brightness, color, and especially longevity vary by brand, and the article sorts all that out.

I couldn't find anything as far as this report from Consumer Reports about CFLs
They are a $$ making company, you have to pay them $$ to read the reviews The fact that they give Behr paint a high review disqualifies them as a reliable resource in a lot of areas IMO They do have a lot of good information But with everything available on the web I'm not paying them for their opinion |
Great write up Dave... thanks!

good information |
They are a $$ making company
They are a non-profit organization according to the masthead of the magazine. You don't want to pay them, don't pay them -- but other people might like to be aware of the option. As with everything, don't treat it as gospel of course. |
Many people do use CR, I'm sure they do have some good info
I worked at Harvard Pilgrim, also a "non-profit" That doesn't mean they can't make $$ - it means they have to spend what they make We installed brand new computers & flat panels company wide years ago to spend profit $$ This was WELL before flat panels were in wide spread use |

CR's evaluation of Behr paint is plainly labeled cost vs. value. They do not say that behr is the best paint on the market, they say based on cost and performance it is the best deal. Application is not a deciding factor. I read the same article mentioned by RDS it is informative. |
I find that CFL's do not last at all in a hallway application as the constant on/off switching greatly reduces life to a matter of months. They also make a poor choice for short term lighting as they take way too long to warm up and obtain optimal lighting conditions. What bulbs would be recommended in this application?
|
Not very good in the cold either, I have them out in my shed and it takes them up to four minutes to warm up when the weather gets a little chilly (below 10*). Do not put them on a light dimmer circuit as they will burn out in short order.

I have noticed a small warm up time, but not that long My bathroom CFL's last on average 3 years with on/off |
I see the ad below this thread advertises packaging to recycle bulbs starting at $34.95. Will we have to pay to dispose of these bulbs as well as pay more to purchase them? Just wondering.
|
Home Depot & other stores have free recycling boxes to dop off used bulbs

Good info! I personally prefer the color of CFL light. It is a brighter, whiter light, which seems to light up a room better. The thing that is unfortunate about them though is the inability to dim them in ambiance setting. My crawlspace only had 2 incad lights, I added 4 more to make a total of 6, and made them all CFLs. A HUGE lighting difference in there now and probably less power draw.
Also with CFLs you can safely exceed the wattage limit of fixtures as they produce way more heat. |
