CCFL Types

I was initial delighted by this product A friend told me that his equipment which read electromagnetic energy went off the scale around these devices. It seems this energy can make people short tempered.

If you want more info I can get it.

I asked my friend who is a Geomancer and he says that he has a machine that measures the EMF and that the field on some of the lights extends three feet. The not so obvious problem is for the people on the floor above the light, they are affected while walking over the field. Some types are worse than others, but he had no info on which ones.

The wave of the future is LED.

John Paul - I'll admit that I'm curious about this - what other information do  you have?

 

Thanks!

I have the same question as Cope.  I don't like the look of fluorescent lighting.  Has anyone found an energy efficient bulb that looks more like incandescent lighting?

 

The n:vision website doesn't have temperature ratings on their site but it looks like their soft white is akin to warm white on the 1000bulbs color scale (i.e. a color temp of 2700k).  Bright white is somewhere between halogen white and cool white (hence the hospital feeling with a color temp rating of 3500k) and daylight is...well...daylight putting it around 5500k. 

 

According to this Popular Mechanics review, the n:vision soft white is a good choice.

 

Also, for another rating of n:vision and some other bulbs, check out this blog post from Shahine.com/omar

Does anyone know of a mercury free CFL bulb? I had someone swear they bought one, but I can't get hold of them to find out which brand it was. I know there are companies reducing the amount from 5 to less than 2 miligrams...but I can't find any info on a zero mercury CFL bulb.

I can't find anything suggesting that mercury-free bulbs exist, but this is a great article from a very credible source abot the considerations around mercury in CFLs, etc. - Eric Corey Freed on the Greener Buildings Site.

 

It mentions the options of Xenon bulbs that don't use any mercury, but that are less efficient and therefore contribute to greater mercury emissions into the air by powering them. Also LEDs are a great option, but the technology still needs some time to improve and come down in price. We have a wiki about recycling CFLs and an article about CFLs and mercury would be great too if you find info.

LOL!  Are you serious?!  I suppose you also don't use a cellphone and avoid anyplace that has a WiFi hotspot.  And I certainly wouldn't trust the advice of a "geomancer". More hilarious info on geomancy: http://en.wikipedia.org/wiki/Geomancy

How gullible can a person be?

I was pretty impressed with how long this thread went on with reasonable and respectful questions & answers - even when a stretch.  It made it all the way to 10 before a flamer lept in.  Pretty impressive.  Thanks Stins & Tricciardi & Deej for useful info.

Up until Ohpuhleeease everyone just ignored the silly stuff in the comment by cope.

Nothing wrong with letting someone know they are posting foolish garbage - geomancers and a friend that has a meter for measuring the EMF around a light? 

If anyone believes that stuff then I have a friend who says he has a machine that converts lighter elements into heavier elements  - he is trying for gold but unfortunately started with hydrogen - he is looking for investors though.
