!±8± Why Are LED Flashlights Better Compared To Incandescent Flashlights

A good quality LED flashlight is much more energy efficient and shock resistant compared to flashlights using incandescent bulbs because of the solid state light emitting diodes used. The conventional filament light bulbs are very prone to breakage from impact and overheating. A light bulb contains a very thin wire that is heated to produce light inside a small glass vacuum tube. This can be very inefficient because a lot of energy is wasted as heat and not 100% produced into light. Furthermore, the thin wire filament deteriorates rapidly with use and that is why incandescent light bulbs must be frequently replaced.

A LED light bulb is actually a solid state light emitting diode based on semiconductor technology. When a sufficient voltage is brought across the two ends of a LED, it will start to conduct electricity and gives off light in the process. The typical LED bulb draws just 5-10% of the energy consumption of an equivalently bright filament light bulb! And it can last up to 10 years under normal usage. This can save you a lot of batteries and money on replaceable parts and consumables.

The color of the emitted light would depend on the specific type of materials and coatings which are utilized. Quality LED flashlights usually produce a near white light beam while cheaper LED bulbs may give off a slightly yellowish or warm light.

You can find a lot of different types of LED flashlights being sold to suit your requirements. There are many sizes to choose from, how bright a flashlight you need, ranging from 10 lumens to 200 lumens etc. Do not be too concerned with having a lot of LED bulbs used within a particular model of flashlight. One single high quality LED will be brighter, last longer and uses less electricity compared to a bunch of low end LEDs.

Many LED flashlight collectors like to buy those with aircraft grade aluminum casing for corrosion, strength and lightweight advantages. However they are more expensive and may not be necessary. For example, you need a floating LED flashlight for water trips, so a cheap rubberized LED flashlight is actually more appropriate for your situation.

A good LED flashlight may cost nothing more than a traditional flashlight, but offer so much benefits that it is easy to choose which one to buy nowadays. It is very reliable and not prone to light bulb failure, and produces a near white light beam with no color distortions.

Proportion Sizes and Eating Habits

!±8± Proportion Sizes and Eating Habits

Few will deny that Americans are getting heavier. As for any problem of this size (no pun intended), there is of course more than one culprit. Here is a look at the role ever-increasing serving sizes play in America's obesity epidemic. More than we realize, proportion sizes fuel peoples' eating habits.

Much of human history was feast or famine. With the difficulties in storing food, killing game, sudden weather changes and all the other problems those who lived in primitive conditions faced, people could never be sure when their next meal was coming. Those who survived and passed on their genes were those who ate as much as they could when food was available.

This era of relative plenty and easy availability of food is very new in human history and not something we are equipped to deal with. There is nothing in our nature that tells us to stop eating when we have had enough to meet our needs. For most people, unless they feel totally stuffed, it is very difficult to say no to another bite when is right in front of them.

However, even in the times when food is easily available, many people can stop eating when food is not right in front of them. For example, while it is not difficult to order more or open another snack, many people will not take that extra step. It is much easier to stop eating when it requires the extra step or ordering again or opening another bag of potato chips. They are willing to stop without gorging themselves.

The changes in food and serving sizes in recent years have taken away even this one last break on out eating. Now, the quantity of food served often goes beyond the point of making someone reasonable full. If the proportions had been smaller, one might not have thought twice about stopping. However, rather than leave that food on the plate or closing that jumbo sized bag of potato chips for next time, it is tempting to keep just eating to the point it becomes physically uncomfortable.

Unfortunately, this extra eating is probably not even giving us any more satisfaction for all the health and other problems that go with it. While the first bites taste the best, every mouthful after them gives us ever diminishing returns. People stuff the food down without any real extra enjoyment. In time, our minds and stomachs expect this extra food, and it takes more food to reach the same level of satisfaction we could once find with far fewer calories. The vicious cycle thus continues.

Seriously addressing this problem, if Americans ever do, is not going to be easy. What and how much someone eats is a very personal and people do not want the government or others telling them what they can or cannot eat. This problem with serving sizes and the obesity epidemic in America are closely intertwined though. Without business, government and consumers working together to find solutions, it is likely to get worse.

Until people directly face up to the fact growing proportions only condition us to eat and expect more, American, and perhaps the worlds', appetites and waistlines are almost certainly going to keep growing.
