How A Light Bulb Works and Other Interesting Tidbits
Light Bulb Science
Ever wonder how a light bulb works? I mean it seems easy, you flick a switch and "bam" there is light! While not much more complicated than that, there is a little science involved.
To understand how a light works you need to understand certain terms including voltage, watt and amperage. The energy a light bulb produces is called the voltage of the light bulb. Amperage is the energy a bulb uses to produce light. Watts is the electrical flow or energy produced by a light bulb. This tells you how much electrical energy flows through your light bulb within any given second.
In simple terms voltage refers to how strong the force of electricity is that flows through a bulb. Current tells you how fast electricity flows and resistance tells you how much space a current has to pass through. All of these factors impact your light bulbs performance.
When you flip a light switch, a current of electricity passes through your light bulb. The filament in the light bulb then heats up, eventually producing a glow or the "light" we are used to seeing. Believe it or not, most light bulbs are more adept at producing heat than they are at producing light. Traditional incandescent bulbs waste far more energy than other sources of light simply because a light bulb produces so much heat. That is of course unless you use your light bulbs to heat a room!
Now, most people go for cheap light bulbs. Why not? Cheap incandescent bulbs produce a sufficient amount of light and come in various shapes and styles.
You may find however, with a little experimentation your needs are best met with another bulb.
Let's look at some lighting preferences to decide what bulb may work best for you.
High Quality Light
If you want lots of high quality, natural looking light surrounding you there is no doubt about it... full spectrum light bulbs are the best choice for you. Full spectrum light bulbs provide bright lighting. The "white light" or natural light they produce is equal in intensity to outdoor daylight. Full spectrum bulbs are a good choice for anyone looking for a pick-me-up. These bulbs provide a full array of the ultraviolet spectrum.
Economical and Long Lasting
Halogen light bulbs are a good choice for someone willing to pay a little extra to get a high quality bulb in the long run. Halogen bulbs provide more light than a traditional light bulb. They also last much longer. You can use them indoors or outdoors. They do get hot however, so keep this in mind when buying.
Soft and Energy Efficient Light
If you want soft, energy efficient light you may consider compact fluorescent light bulbs. Compact bulbs produce light that is similar to incandescent bulbs, only softer. These light bulbs also use far less electricity than standard light bulbs and last much longer. Because of this they are a good value. You can use compact bulbs in almost any ordinary lamp. Most cost the same as traditional bulbs, so you save money in the long run. Most compact bulbs last up to 10,000 hours. That's several year's value in a light bulb.
Of course, if you have specialty lighting needs there are various bulbs to choose from. Projector light bulbs luminate your projector if you have a projector for personal or business use. Tanning light bulbs, much like full spectrum light bulbs, provide a high intensity light. Tanning bulbs mainly emit ultraviolet A and B light to help tan the skin.
Need a bulb for your automobile? Chances are you need an automotive LED bulb. No problem. Chances are the light in your car signals won't go out for a long time. If you want a light bulb that won't go out, the LED bulb is the best choice for you.
Now you know what types of bulbs are available and how a light bulb works. Always remember there is a light bulb out there for any lighting need! Happy lighting!

Enemy UAV Defense is under consideration
Unmanned Aerial Vehicles should be shot down from the air rather than the ground because if they are flown tele-robotically the operator who is looking down and forward will not know where the anti-aircraft device is. If the enemy uses Unmanned Aerial Vehicles to draw fire, which is a smart move for them, then once fired upon the Unmanned Aerial Vehicle whether it is shot down or not has now located our weaponry and troops.
Welcome to the Eye Science
Thousands of dyslexic students, across the UK, are referred of something called "Asfedic tuning", this is a procedure that supposedly results in a precise identification of a persons optimal background best suited for acquiring the optimum reading speeds. Here are my notes about this: Is this Aprotocol@ a form of unconscious sensory teaching that Arecalibrates@ the retinal receptors to filter the returned spectral frequencies of light returned off the perimeter of the target object? Or is there a more fundamental brain architecture reprogramming process involved.
I am beginning to wonder if scientists have been getting it all wrong. All this time, people have been worried about the Ozone, or a giant asteroid, or some breakout of a bio-hazardous agent by a terrorist organization being the doom of mankind.
A Wake Up Call To The Scientific Community
Nature has millions of intervowen interrelationships among the numerous flora and fauna. Such relationships are the basis for the food webs and food pyramids.
Lets Get Dirty
There is no right way of saying this, so I'll say it the wrong way: in order to stay healthy we must stay dirty. Now, that didn't sound right, did it? Put it this way: if we all lived in sealed apartments where only the purest air was pumped in and every trace of bacteria were eliminated from our food we probably wouldn't last long when we stepped outside.
Preventing Death in a Bio Threat
In the event of Bio threat how to mobilize Hospitals in case of biological emergencies should close except for broken bones and accidents. Instead those who believe they have contracted a biological terrorist induced pathogen, virus or disease should be required to stay at home.
The Future Enhancements of Tele-Robotics
Today we have already available UAVs, which will soon have the capacity of operating together in swarms, controlled from another nearby aircraft. We have UAVs, which can be flown by a pilot sitting at a desk more than 1000 miles away.

Making a Lightening Storm?
Here is a very basic concept idea/plan to harvest energy from Lightening. It is done in an artificial chamber, simulating weather in the atmosphere, but under exact and controlled circumstances; still in the incubation-thinking phase.
Stem Cells (The Truth)
The much publicized stem cell research debate focusing on moral arguments is off target with the goal of real progress in the direction of human physiological benefits potential. No matter what side of this issue you come down on, practical considerations ultimately trump this emotionally clouded subject.
Mini UAV and MAV Power Plants
A set up of harnessed Lithium Polymer Cells can be the answer to mini-UAVs. When we compare the voltage output and capacity of wire harness systems and compare the weight of LiPoly cells to NiCd or NiMH cells you can achieve extremely better results than the average fuel and output on a ounce per ounce basis.
