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.

There is no UV damage to increase. You get more UV from a few minutes
in the sun than you'd get from a year of sitting near a lamp.

Edison base light fixtures are getting phased out; so hoarding bulbs is
silly.

Cheap [!] OLED screw-in bulb replacements can't get here soon enough...

....and "smart cars", dammit!

Where's my smart car!!

Rickmers, you're silly.

First I've heard of that, all my CFLs use Edison bases.

Per someone's posting;
I informed myself about the GU-24 interface proposals
and now stand corrected.
I imagine there will be adapters available for some time to come
such that I don't have to scrap my supply of edison base CFLs.
I no longer have any incandescent environmental lighting, and the only
incandescent sources at all is the display on the Kenwood TS-2000.

The lamps in my refrigerator and in my oven are still Medium Screw base
incandescents. That and the Festivus lights...

Even all the flashlights are all LED nowadays.

Not all, but the superior ones are. They now make Luxeon single LED
flashlights up to 10 watts (perhaps even higher) that outshine any handheld
incandescent flashlight (except perhaps the heavy duty halogen flashlights
that will only work for a few minutes on a fully charged battery) with a
very good quality white light. I have one such Luxeon flashlight with a 3
watt lamp that is about 1/3 the size of a two "D" cell flashlight that is
many times brighter and has a better beam.
