My florescent lights need a shake or a hit to work


This week’s Well column in Science Times focused on pediatric migraine and why back-to-school time, with lost sleep, skipped meals and other bad habits, can trigger migraine pain.

But a number of readers identified what they believe is another culprit — the fluorescent lights common in schools and other public buildings.

“I suspect the lighting in many classrooms could be a contributing factor. When I work in a room with overhead fluorescent lighting I feel a migraine coming on within a couple of hours,” wrote reader Suki.

“If the school has magnetic ballast fluorescent lights, these may be triggering migraines. Much better to get the lighting changed than to take drugs!” suggested LeAnne Willson.

Andrew D. Hershey, M.D., Ph.D.

But is it true? I asked Dr. Andrew Hershey, director of the headache center at Cincinnati Children’s Hospital Medical Center and one of the nation’s leading experts in pediatric migraine. He says there isn’t evidence to support the...

Call it environmental productivity: the science of how your space supports (or handicaps) the work you do. It’s the kind of insight that design firms like Steelcase–which has an office anthropologist and has rethought virtual meetings— traffic in, with the goal of helping workers to thrive, rather than simply survive.

To that end, Widrich found key factors: light and warmth.

We’ve all felt the brightly lit darkness of a minimally windowed, fluorescent-flooded workspace, and new research by Mirjam Muench shows just why artificial light looks (and feels) so damn hideous.

According to his study, people who had a diet of daylight were “significantly more alert” at the beginning of the evening while the sunshine-stricken were “significantly sleepier” at the end of the evening. The Swiss neuroscientist concludes that even short-term afternoon lighting conditions have an impact on evening task performance, which sheds some light on the 4 p.m. slump–we’re not getting...

You see them in every grocery store and home center – those funny-looking curly compact fluorescent lights (CFLs) that are rapidly replacing the old round bulbs. And pretty soon, the Energy Independence and Security Act of 2007 kicks in, requiring bulbs to be 25 to 30 percent more efficient by 2012 to 2014, and 70 percent more efficient by 2020, effectively phasing out traditional incandescent bulbs as a way to save energy and reduce greenhouse gas emissions.

The energy efficiency of CFLs may be significant, but unlike traditional light bulbs, there is a hidden danger sealed inside each little bulb that requires special handling and disposal.

Mercury – a potent, developmental neurotoxin that can damage the brain, liver, kidneys and central nervous system. Infants and young children are particularly vulnerable to mercury’s toxic effects. Even at low levels, mercury is capable of causing a number of health problems including impair motor...

Maria D. asks: Why do fluorescent lights buzz?

Comprised of a sealed tube coated on the inside with a phosphor powder and filled with (usually) argon and a tiny bit of mercury, the way in which fluorescent bulbs produce light is extremely fascinating.

While the underlying physical mechanisms in the fixture and bulb can vary a bit in design, in a nutshell a fluorescent light works via two electrodes at either end of the tube emitting electrons as they heat up. Eventually, an arc is created (via varying mechanisms depending on the fixture and bulb design) with the electrons shooting across the bulb through the ionized gas from one electrode to the other; as they move through the tube, the tiny bit of mercury in the bulb is vaporized and as the electrons collide with its atoms, it excites the electrons in the atoms to higher energy levels. However, this higher energy level is unstable and post-collision, as the electrons rapidly return to their original energy level,...

Interesting to read this thread, as it's been progressing over seven years. Sadly most people are offering suggestions to treat the symptoms, but not keep them from happening. Also disheartening to see others completely dismiss the issue. No idea what prompts a person to log-in and post something condescending.

I started looking into this after experiencing what others have. I have a history of migraines, but they were worsening since I started my current job. I also other issues. My vision at work wasn't clear, a bit cloudy, and I wasn't able to fully focus visually. I was also getting regularly nauseated. I brought this up with my employer (I work in a cubicle farm, in a long row, rows of lights all around) after doing some research. I had concluded it was the lighting, as I can see the bulbs flicker, and peripherally the glare distorts my vision. My employers first reaction was to have an ergonomic expert come out, but even he admitted that he has no expertise in...

Long ago I was taught that the gardener has a "fundamental choice" to make: either to grow only those plants adapted to his conditions and his care, or to modify his conditions and care to suit the plants he wants to grow. Either approach will work.

So, can bonsai be grown indoors? Certainly. You can do this if you really want to . . . probably more easily than you think. Visit the website and read about David Fukumoto's "True Indoor Bonsai." These trees are almost foolproof plants adapted to long term survival with minimal care at very low light levels. Then, at the other extreme, re-read Jerry Meislik's account (this website) of how he grows banyans and other tropical species luxuriantly under high-output metal-halide lights. And, finally, read my fluorescent light bonsai recipe offered below for one more option. Of course, yet another possibility is to grow bonsai indoors keeping them...

I guess i'll make it clear now

we all hate ourselves

how many more now? Drive myself insane before i've driven everyone away

if i could walk for a moment of this (bar?) til i hit the floor

if i could walk from one end of this town

to the other

goes away

the only reason people try to talk to each other

is cos they gotta say something

that is smarter than the other one said

everyone's fucking crazy

people never listen to what you have to say

cos their so damn scared

that you'll be smarter than them some day

everyone's fucking crazy

but i hate these flourescent lights

if i could walk for a moment every spore and cell

i'd hit the floor

if i could walk from one end of this town

to the other

i wouldn't go anywhere at all

i could talk to you and you could talk to me

i would say anything at all

i could...

You used to get it in your fishnets

Раньше ты занималась этим в колготах в сеточку,

So now you only get it in your night dress

Теперь - только в вечерних платьях.

Discarded all the naughty nights for niceness

Отказалась от отвязных ночей из соображений приличия,

Landed in a very common crisis

Погрузилась в банальный кризис взросления.

Everything's in order in a black hole

Всё по очереди затягивает черная дыра,

Nothing seems as pretty as the past though

Настоящее не такое яркое, как прошлое,

That Bloody Mary's lacking a Tabasco

Как Кровавая Мэри без табаско.


Remember when you used to be a rascal?

Помнишь, какой бунтаркой ты была раньше?

Oh that boy's a slag

Тот парень был просто кобель,

The best you ever had

Но он был лучшим из всех.

The best you ever had

Лучший из всех -

Is just a memory and those...

12v Fluoro Inverter

Build this 20 watt Fluoro Inverter,
it drives two 20-watt tubes or a 40-watt tube!

Read: Living with 12v
see: Project in use on a farm

The kit comes with PCB and adjustable brightness

This is a low-cost project for 20 or 40 watt fluorescent tubes. However the most efficient is to use a 40 watt tube (or two 20 watt tubes in series). It's a circuit you can put together from junk box components or build from a kit. It's very simple to build and requires no printed circuit board.
The transformer is hand-wound on a ferrite rod (from an old transistor radio) and the winding wire can be salvaged from an old transformer.
We are purposely keeping costs down to show how cheaply it can be put together.
Depending on your stock of parts, the cost could range from $3.00 to about $15.00 and if the wires from the transformer are...

Twenty five years ago, when my first experiments with growing little trees under fluorescent light began, I had one distinct advantage over today's bonsai beginners. At the time, I hadn't read a lot of books and articles making the whole project sound almost impossible.

I hadn't been told you have to mist the foliage regularly. I hadn't been told I'd need a humidifier or cool mist vaporizer. I hadn't been told you have to run a fan to circulate air. I hadn't been told cheap, cool white, fluorescent tubes need to be supplemented with incandescent bulbs. And, I hadn't been told most plants grown indoors still need a cold rest period with temperatures below 50°F. for several weeks each year.

READ THIS CAREFULLY! I am not following today and have not followed any of the procedures listed above. This is not...

Cheerleaders' Rape and Torture

This is the story of 5 high school Cheerleaders' who get lost and have their car breakdown, only to have a friendly garage owner "help" them out and turn them into slaves. Thanks for reading…Semiater (

Cheerleaders' Rape and Torture

Chapter One

It was a crappy night out, raining, cold, all and all miserable. The funny thing is, I wasn't even supposed to be at the shop. It's my garage, but I have a guy that runs the place for me, and I usually sit at home "managing" from a far. It's a good life, I can't complain.

I was sitting at the counter watching some of the Monday night football game. I was in the shop trying to get a bunch of paper work done, and I ended up staying late. Everybody else was gone and wouldn't be back in till morning, and the game had already started, so I figured I'd stick around till half time, and then head home after that.

I was pretty pissed when I heard...

I was reading an article on WebMD that stated “most teens and adults with autism have less severe symptoms and behaviors as they get older, a groundbreaking study shows” You can read the full article. here

While working through the writing of my memoir, Twirling Naked in the Streets…, I have been contemplating what my life “looked” like when I was a young child with autism, as opposed to how I “look” symptom wise as an Adult. What I am seeing is that my autistic traits were readily visible when I was very young, I disguised them in my teen and early adult years, and in my later adult years (after child rearing and marriage etc.) the traits have reappeared in a sense.

By reappearing I am not suggesting that they ever went away, only that they are more apparent and troublesome today than they were in many days past. My “symptoms” seem more pronounced now that I am older than they did when I was a child.

Of course I have learned to cope with many outside factors...

“One of the first calls I made when forming sports nutrition an advisory board was to Veteran Sports RD, Dave Ellis. I first met Dave back when he was the Sports RD for the University of Nebraska and witnessed his unique ability to apply complex metabolic research in a way that athletes and coaches could understand. Few in the trenches of athletics have that skill or the patience to keep up on the science.”

--John Ivy PhD, Former Kinesiology Department Chair

University of Texas

"One of our valued advisers here at USADA is Veteran Sports RD, Dave Ellis whose insights into the trenches of athletics is unparalleled. Few navigate all levels of sport like Dave which gives him a very unique perspective on the challenges we all face with fueling and anti-doping issues."
-Travis Tygart, CEO
US Anti-Doping (USADA)

Today, a startling new discovery: prodding the brain with light, a group of scientists got an unexpected surprise -- they were able to turn back on a part of the brain that had been shut down by Alzheimer’s disease. This new science is not a cure, and is far from a treatment, but it’s a finding so … simple, you won’t be able to shake it. Come join us for a lab visit, where we’ll meet some mice, stare at some light, and come face-to-face with the mystery of memory. We can promise you: by the end, you’ll never think the same way about Christmas lights again.

Many pests exist out there that cause problems for your house or yard. Ants, rats, spiders – they can pop up without warning, leaving you to deal with their removal or extermination. One such problem you may encounter is a yard mole. Most don’t even think of these creatures when imagining a pest in their yard, but the problem is real. Moles are small, furry animals that spend their time underground. Their large forearms are ideal for digging through the dirt where they burrow, eat earthworms, and stay mostly out of sight. The issues you go through in regards to a mole in your yard are sometimes mild, but sometimes severe. Luckily, there are ways to get rid of the animal.

Signs That You’ve Got a Mole in Your Yard

Everyone has heard the saying “Don’t make a mountain out of a mole hill.” Mole hills are a telltale sign that you’ve got the creatures in your yard. When Moles burrow, they use their large paws to dig out so much dirt that it piles up outside the hole. Mounds...
