Question:  How many psychiatrists does it take to change a light bulb?

Answer:  Only one…but the light bulb has to really WANT to change.

Maybe you’ve heard this joke before.  And, maybe you are tired of hearing light bulb jokes in general.  But, like it or not—Change is inevitable and the LED light bulb is leading the way.

Nearly a day goes by that we do not hear about light emitting diodes (LEDs) and the changes taking place in the lighting industry.

And, for good reason.  LED is changing the way we see the light.  The latest ceiling pendants, mini chandeliers, task lamps and outdoor light fixtures are accepting these new bulbs with tremendous gusto.  The lighting effects are becoming more versatile and redefining our vision of elegance.  The price of LED lamps is even coming down.

As LED light fixtures become more affordable and user-friendly, the choice of which bulb to use in your next lighting design will be clear…or frosted or soft white or blue…but it will be LED!

1.  LEDs lasts up to 50 times longer and use 80% less energy than old standard incandescent light bulbs.

2.  LEDs burn out slowly over time, so the dreaded pop and bulb blow out will be a blast from the past–something to tell your grandchildren about!

3.  LEDs radiate little to no heat and they hold up extremely well in harsh winter weather conditions.

4.  LEDs are eco-friendly; they do not contain toxic gas or emit harmful IR/UV radiation.

5.  LEDs are also referred to as “solid-state” lighting  (SSL) because they use semiconductors and are solid light sources; they are shatter-resistant and durable.

Embrace change. Learn the facts and put LED to work in your home or office environment.

√ Buy from a reputable dealer.  All LED bulbs are not created equal.  Through a process of “binning,” LED chips are sorted according to the quality and degree of luminescence.  Cheaper LED bulbs may be equipped with a lower quality chip that will not provide the brightest light and may burn out prematurely.

√ Look for Energy Star®-ratings to find LEDs of the highest quality.

Some of the latest LED innovations include designer mini pendants and ceiling fixtures from ELK Lighting.

Summer is not typically a season we need to worry very much about huge power outages. However, this is a good time of the year to consider what your generator needs are, before you actually do need it in the winter time. Homeowners in the Midwest are subjected to cold weather and winter storms on a yearly basis, which is made worse when severe weather knocks the power out.

Many homeowners might rely on a portable generator, but this might actually be insufficient for all the needs of your home. Additionally, they only function for a limited amount of time. For this reason, we highly recommend the installation of a whole-house standby generator.

Comfort: When winter does roll around again next year, you’ll want a reliable heating system. But most heaters won’t function with a complete loss of power—not even natural gas heaters as most require an electrical ignition these days. Huge power outages typically happen during extremely cold weather. The right standby generator can make sure that your heater is able to do its job, keeping you and your family warm.

Safety: Does anyone in your home rely on electrically powered devices for some type of medical condition? If so, it’s essential to have an effective standby generator. Should you need electricity for any medical reasons, it’s time to inquire about a whole-house standby generator.

Portable Generators are Insufficient: As we mentioned briefly above, portable generators are often insufficient for all the needs of your home. This type of system can be fine for a small camping trip, or even to keep in your car in case of emergency. But they are not designed to power an entire home, and won’t last long enough if you try to use it for such purposes.

Peace of Mind: This is perhaps the biggest benefit of having a standby generator installed. Even if you never face a significant power outage in your home, you’ll always know that you are prepared should one occur.

I have never had the privilege of seeing the northern lights in real life, but my sister lives in northern Canada and has told me about them. (She’s a pretty credible source: She even named her daughter Aurora.) After asking her, “What ARE the northern lights,” several times, I now understand the aurora borealis to be a visual effect of the collision of solar wind and magnetospheric charged particles with the thermosphere. Can you see why I had to ask what the northern lights were more than once? The northern lights are most spectacular near the North Pole and during spring and autumn equinoxes. (And, by the way, no. The northern lights are not Santa’s off-season hobby.) But the northern lights, if there are some geomagnetic storms a-brewin’, can be seen closer to home, too, visible occasionally as far south as Chicago or New York.

Anyway, this guy Winiarcyzk is an astronomy enthusiast who lives in Caithness, which is at the tippy top of Scotland. There’s isn’t much light pollution way up there, so it’s a good place for such a sky-minded person to live and enjoy his hobby. Wonderfully, with this time lapse video of the northern lights, we get to enjoy his hobby, too.

Take a look. Have you ever seen anything more lovely occurring in nature? You know, with all this solar wind, magnetospheric particles, thermospheres, and geomagnetic storms, it sure seems like there is a lot more going on in nature than we can readily sense.

The most common definition of a distributor is a mediator or a supplier between a manufacturer and a retailer. Though this doesn’t sound as complicated or complex, the job of a distributor does not involve only supplying and can include consultation as well.

There are different types of distributors functioning in the market and one of the most crucial lines of businesses in this field is electrical distributorship. As with every job, you need to have the right approach and roadmap if you are keen to take this up as a career. The following tips will help provide a better idea.

High temperatures cause conductors to expand and hence increase in length. The converse is true for low temperature conditions. The change in length varies from one conductor to another depending on its thermal expansivity. The length of copper conductors, for instance, changes by 5 feet per 1000 feet of length when the conductor temperature changes from 100 – 0°, while aluminum changes by about 7 feet. The length increases with increase in temperature and reduces with reduction in temperature.

This increase or decrease in length is of great concern when installing power transmission lines between poles and towers, or when installing other power connectors. There must be an allowance for this change in length since it can cause catastrophes if it’s not there.

Weather changes are associated with increase and decrease in temperature and thus affect power transmission lines and other conductors. However, change in temperature is only one factor that affects power lines. Below are the changes that occur to power lines and other conductors as a result of weather changes:

The amount of heat dissipated from power conductors is reduced during hot and calm weather conditions. Basically, if the temperature of air around the cable is low, more heat is lost from the cable to the air. If the air is already hot, the exchange of heat is lesser. This low heat dissipation causes the lines to overheat. However, the rise in conductor temperature (overheating) worsens when cables are transmitting too much power than required. The first effect of this increased conductor temperature is snagging, which is the downward bulging of the cable between two poles, caused by the increase in the length of cables.

Snagging is largest during extreme hot weather (largest increase in temperature) conditions experienced in summer. The increase in length results to downward bulging of the cable due to the effect of gravity. Excessive sagging is dangerous if it goes below the accepted height clearance – cables could come into contact with trees, buildings and other structures underneath, causing electrocution and fires.

Excessive sagging represent an added weight on the power line and this increase may cause the line to fail or to pull down weak poles and towers. The effects can be small but gradual and so the poles and towers will finally come down or require some adjustment/replacement after some time, which is costly. This sagging can also cause the lines to short out. Excessive sagging is also costly since it leads to increased electrical resistance. This means that a sagged power line transmits lesser current than it normally does, thus causing under-feeding of electrical equipment and industries. It is also costly and time consuming to rectify a sag.
