And you thought it only put crap in your radio. turns out
these un-researched lights can kill you. 16X9 is a 20X20
north of us. you might want to read the story and watch
the videos. and, keep your kids away from them. once again,
Big Gov goes with Big Biz, and screw the people.

CFL's are nothing more than screw-in fluroescent lamps loke the types
we've had since the 1930's. Remember that fluroescent tube lighting
over your head in grade school and at Woolworths store when you were a
kid? It's exactly the same thing in a CFL except the tube is a curly-
cue shape instead of a long tube. CFL's ane not dangerous same
technology we've had since the late 1930's.
No they are not the same. The old bulbs operated at 60 Hz and the new
smaller bulbs operate in the kilohertz range. The other problem is these
smaller bulbs are used closer to people increasing the UV damage.

And just how much UV do you think is actually escaping from the bulb?
You'd get way more UV from being outside on a clear day than from being
close to a CFL. If they can make CFLs to be used in a photographic lab
you know the UV light actually being emitted has to be extremely low.

The mercury plasma in the bulb emits only UV light. The phosphors on the
inside of the bulb emit visible light when struck by the UV light waves..
This is why florescent lights are biased biased toward the blue.

The light falls off as an inverse square of the distance so the smaller
bulbs closer to you give you UV light at a higher rate.

- Yep, I know those particular factoids.
- The thing is that the phosphors are designed
- to absorb the UV light and re-radiate it in the
- visible range. Unless there is a problem with
- a section of the bulb not having sufficient
- phosphor coating, the UV light getting through
- should be very low.

CFL's Have More Positive Pluses Then Bad
