My bad, I meant the Wiley one with the peer reviewed manuscript.

Re: Another Reason to Not Use CFLs... said by cableties:I never liked the CFLs. Ugly color temp. Yellowing base. Noise.
I know they have mercury in them (very low amount).
You can get CFLs in any color temperature you want, but it is so much easier to just complain about them.
Noise? Incandescents make noise too. Yellow Base? Why does that matter? |

UV is really easy to block. A piece of clear polycarbonate plastic a half millimeter thick will block ALL the UV from a fluorescent lamp. They make sleeves for fluorescent tubes that both prevent them from making a mess if they're broken, and block all UV. Something similar should be relatively trivial to do for compacts.
But this is still a lot about nothing. The intensity of light from the sun is many thousands of times more than that from a compact fluorescent. Letting the sunlight hit your skin for 10 minutes would be equivalent to a year's exposure to CFL illumination. |

Elevated utility bills from incandescent lighting causes elevated blood pressure potentially leading to heart attacks, studies show.
I wonder had they put those cells under the sun light, if the results would be the same or worse than with fluorescent. |

said by bemis:This is some what scary because I do use CFL's quite a bit... in fact I have a "150W" (which are huge) that sits in a silver bowl clamp light, I use it for detail work, so I'm under it, at close range for a few hours at a time...
One thing I have noticed about CFLs is that the light tends to leave me night blind for longer... for example, in my bathroom I have two recessed lights and a vanity light... the vanity is incandescent bulbs and the recessed are CFLs. The emit about the same level of light in the room when position is considered... I started noticing that if I ran the CFLs (regardless of whether I run the vanity or not) when I turn the lights off my vision is completely blank for several seconds... if I run the vanity only, the same thing does not happen. The vanity consists of (4) 60W bulbs and is actually closer to eye level... the recessed are (2) 13W bulbs. That alone has had me a bit nervous as to what CFL light is doing to my eyes...
CFLs produce more blue light, which is what kills your night vision. A trick to preserve night vision without having to actually stay in the dark is to wear amber, or even better, red tinted goggles, or use amber or red lighting. Your 60 watt incandescent lamps are... you guessed it; amber in color. |

2.5 cm!?!?! I get a burn from an incandescent at that range over 2 hours. |

2.5cm is 1 inch. You cannot be with in one inch of any light, Even a standard table lamp the shade is at least 4 inches away if not more. and a standard height ceiling is 8ft off floor level so a normal height person is 2ft away even standing right under it.
These studies are full of shit, Do the test with CFLs at normal everyday distances and then get back to us.

I pulled out a cfl bulb from a lamp that had went out after about 18 months. The base where the glass tube enters was somewhat melted and burned. That kind of concerns me.

...as for wearing red tinted goggles to the toilet at night... they already think i'm weird, this would put them over the edge  |

said by tmh :said by SparkChaser:You are basing all of this on an abstract?  Or do you have the full paper
The question is still valid. This is a paysite. Unfortunately, many papers are distributed this way.
More info questioning the research:
But in contrast to media depictions of “skin-frying” CFLs, researchers are reluctant to draw conclusions about consumer risk on the basis of these findings. “The UV measurement procedures are not described, so one cannot evaluate the data,” says Mats-Olof Mattsson, a cell biology professor at the Austrian Institute of Technology. The authors also reported higher UV emissions than other studies have found3,4,5 and did not follow international measurement standards,6 he adds.

Same thing happened to me as jkj860. I recently remove a CFL that wasn't working. I had a horrible burned smell coming for it and th base where the tube connect with the base of the light was burned. I now use LED lighting. Cost alot less in electricity and generate alot less of eat. you can remove the bulb even after hours of use.

I think small CFL replacements for home lighting have been a bad idea from the start, more so when they were made less expensive by cutting corners. However, the last thread I was in, expressing concern about CFL's was a bit nasty. Those who have bought into CFL's, are going to defend their purchase regardless of any fact presented based on my experience in this board.

LED's don't use massively less electricity than CFL's. I've got both and the wattage is very close, within 2 watts. And LED's get hot too - the Ecosmart 40w LED's I've got in my ceiling fans get very hot in the heatsink area. As do the Ecosmart MR16's I've got in our track lighting.
I like LED's a little better than CFL's as they are instant on and, in theory should last longer. I do use CFL's as LED's cannot be used in enclosed fixtures at this time. The CFL's I get make no mention of not being able to use them in enclosed fixtures.
We've moved into a new house and I'm going around replacing the incans with more efficient light (previous owners loved that nasty incan light). Fixtures I think we will get rid of in the next year or so get CFL's. Fixtures we're keeping get LED. |

| It's kinda strange that your LED gets hot because i have both Light buld led and GU10 led and the are warm but not hot. I can remove them by hand. The buld and the GU10 are equivalent to 50w lights. I recently replace halogen GU10 because they were overheating the recessed socket in the ceiling. The LED are philips hue Lightbulb and stay warm to the touch from base to glass even at max power. Do you use dimmers with those ? some might not be dimmable.

Yet cutting corners is something that's being done with LED as well. What's the best alternative? Incandescent?
said by pandora:However, the last thread I was in, expressing concern about CFL's was a bit nasty. Those who have bought into CFL's, are going to defend their purchase regardless of any fact presented based on my experience in this board. These days, there's no such thing as "investing" in CFLs. They're 2$-3$ a bulb. What we/they are defending is our choice not to go spend 15$-30$/bulb for LED.
Other studies confirm that yes, UV from fluorescent is bad, but the safe distance is way shorter than real life distances.
»en.wikipedia.org/wiki/Fluorescen···ion_risk
quote:
The report states that most bare spiral lamps tested gave off more UV than the 60 watt incandescent lamp tested, but that the double-envelope CFLs emitted less UV. At 30 cm distance, the recommended maximum daily exposure was attained between 3 hours and 6 hours, with little difference between the studied 60 Watt incandescent lamp and any bare-spiral CFL. The report states that the Threshold limit values used represent otherwise healthy individuals who are not experiencing any hypersensitivity conditions or exposed to substances that increase UV sensitivity. Outdoor sunlight can supply the maximum recommended daily UV exposure in 20 to 100 minutes.
said by Hyrules:It's kinda strange that your LED gets hot because i have both Light buld led and GU10 led and the are warm but not hot. It depends on the heat sink on the bulb. Some are bad, some are good. Either way, LED ballasts head up (hence the need for heat sinks). |

Because yes it cost us 180$ for 6 GU10 LED lights. That's about 30$ a light. Although they are supposed to last 25 years which is about 5 times the duration of a normal CFL. Like the CFL, the LED are only starting in the market and they are not cheap as were the CFL in the beginning. They will get cheaper in a couple of years. Anyway the marketing scheme today is that almost anything does not last long unless you pay alot for it.
