How to Choose the Best Ceiling Fan for your Needs?

Ceiling Fan Reviews – How to Choose the Best Ceiling Fan for your Needs?

By: Mark van Tuel

By basic standards, a ceiling fan is something used to either heat up or cool down a room. There are several factors such as blade size, shape and motor speed to consider when purchasing a new ceiling fan. Ceiling fan reviews help a buyer determine the right ceiling fan units to purchase.


In its basic form, a ceiling fan suspends from the ceiling of a room and utilizes hub mounted paddles that rotate in a circular fashion. Air circulation is generated by the movement of the blades. This circulation provides a cooling or de-cooling effect as needed.

To work as a cooling agent, ceiling fan blades move in a counter clockwise motion. In this direction, air circulation generated by the fan blades will evaporate sweat on the human skin cooling the body down. This in turns brings the room temperature down.

The second use moves the fan blades in a clockwise direction capturing the heated air that has risen to the ceiling. As the heated air moves down the walls to the floor, the chill is removed from the room.


The most common ceiling fan operation entails a pull chain/pull chord control that extends downwards from the operational center point of the ceiling fan. This controls the fan speed cycle that can be set to high, medium, low or off with a pull of the chord.

The next ceiling fan operation setting is a variable speed control. For this setting, a hand controlled dial sets a different speed for the fan. A variation on this mounts the speed dial on a nearby wall as opposed to the fan itself.

New ceiling fans emerge onto the market displaying a wireless remote control system. Working in much the same way as a television remote, an infrared beam is sent from a hand held controller to the fan controlling operation with the touch of a button.

Purchase Factors

Consider the power, size and durability of all ceiling fan motors before making a decision. Although a larger fan is going to be more expensive than a smaller model, it will have more power and longer durability. This will keep the ceiling fan running without so much as a wobble or noise from wearing down.

Another purchase factor is the overall durability and performance of a ceiling fan.

Take into consideration the size, shape and pitch of the fan blades. Also consider the height distance between a ceiling fan and the actual ceiling in a room. If the ceiling fan is going to run too close to the ceiling, it will undoubtedly affect how the fan operates.

Ceiling fans are available in a wide variety of shapes, sizes and colors. Taking the time to become educated on all the different variations of ceiling fans will ensure the right fit for any home or office.

Fuses replaced with pipe. Dangerous!!!

fuseImage via Wikipedia
From Drop Box

Small fusesImage via Wikipedia
Here is an old fuse panel that has pieces of metal cut and fitted into where the safety fuses belong. This is a dangerous situation!! The wiring is older then dirt. The fuse box is is so corroded that you could rip it apart with your bare hands. This is the kind of nightmare situation  find in the basement of some homes that were not maintained.

Too often this is in the homes of the elderly who never thought that they needed to up date their electrical systems.  There was a time when handymen would just put a penny in the fuse box to fix an electrical problem. In this case they used copper pipes. Now, this circuit is no longer fused. There is nothing stopping it from drawing too much power. The wire can become like toaster coils and start a fire.

Solar Energy a Reliable and Practical Source

Solar Energy a Reliable and Practical Source

By: Energy Matters

These days we are experiencing a growing awareness to the fact that our energy resources, as they have been used in the last few years, are probably not going to last for long and that the energy markets are exposed to more and more rapid changes, some due to political reasons and others because of the changing climate of the planet.

Solar energy is a renewable free source of energy which is sustainable as it is not inexhaustible, unlike fossil fuels which are finite. It is also a non-polluting source of energy and it does not emit any greenhouse gases when producing electricity. The solar electricity that is produced can supplement your entire or partial energy consumption. Using solar energy means reducing your energy bills and saving money. Also having solar PV panels adds value to your home, they are low maintenance and unobtrusive. Germany is the global leader for solar-generated electricity.

Why choose solar energy?

Australia is the luckiest country in the world. Our geography gives us the opportunity to use the most natural, sustainable and clean energy in our homes – the energy from the sun.

Solar thermal applications are the most widely used category of solar energy technology. These technologies use heat from the sun for water and space heating, ventilation, and many other applications.

Solar energy is not a new concept, it has been properly introduced to the global public many years ago and successfully implemented in different parts of the world in different ways, so we can say that solar energy is known to most people, but it is still not as popular as it should be, as a cheap replacement for other sources of energy. The energy of the sun, from its direct sun rays that are projected directly at the earth or by giant wind turbines are free fro us to use, to manipulate for our needs, and this can be done by almost anyone in any place, it just needs to technology and the know-how.

Lighting Up Your Home With Leds: is it Time to Upgrade?

Increasingly consumers are turning their eyes towards LED house lights as a way to conserve electricity. But will you really achieve the greatest savings by buying this still expensive lighting now? Or would you be better off to save your money for the time being, or to buy other energy-efficient light bulbs, and use the money you save in electricity to buy LED house lights down the road?

You have most likely seen LEDs before: camping headlamps, LED Christmas tree lights, wind-up emergency torches. How about LED house lights? If LEDs are so efficient, why aren't manufacturers lining up to sell LED lights for the home, and why aren't we lining up to buy them?

I wouldn't try to sell you on LED lights as a solution to high utility bills or as the most ecologically beneficial lighting solution around. Frankly, I think LEDs have a ways to go yet, in terms of function, durability, and economy. There are some LED products you should consider over the next year, such as LED Christmas lights. And you might enjoy trying out a couple of LED light bulbs, if you're the energy-saving type. But you are going to save more money by keeping with your current lighting, and migrating to fluorescent lights in the next year or so. Compact fluorescent lights, or CFLs, have a payback so short that they'll pay for themselves before LEDs have matured enough to make CFLs out of date.

LED light bulbs are more efficient than incandescent or fluorescent lighting. The problem is that LEDs have very directed light. An incandescent light shines over a wide area fairly evenly, while LED lights are very focused, so that the area they directly illuminate is very bright, while the further you go from the direct beam, the less light there is. For LED Christmas lights, that isn't a problem; you just want some shining points of light, which LEDs do very efficiently. But an incandescent or CFL will do a much better job of brightening up your living room than an LED bulb in the same application. The light will be more evenly and broadly spread, and with a warmer color.

When you see LED packaging claims of LED light output, you should be doubtful. A number in Lumens, which indicates light brightness, is misleading for LEDs, because of their focused beam. Lumens levels are read from a sensor placed right underneath the light source. A household LED light bulb at 2 watts may have the same lumens rating as a 50 watt halogen bulb, or as a 15 watt CFL, but the LED lamp may only send a focused light directly under it to the photo sensor, while the incandescent light and CFL will light up a much broader area, and still give that same lumens rating for the area immediately beneath the bulb. This may be the source of a frequent negative comment among LED owners, such as: "The packaging claims this 2-watt LED bulb has the same light output as a 50-watt incandescent bulb but it feels more like a 25-watt incandescent if you ask me."

When it comes to halogen lights, they are only as efficient as incandescent lights, so the same efficiency considerations apply here. But since halogen lights are typically much more direct than incandescent bulbs, LED lights that are designed to replace halogen lights are both more efficient than the halogens they replace, and work well for the direct light that halogen bulbs provide. You can find LED replacement bulbs for the most common halogen fixtures such as GU10 and MR13, and this may be a good place to start the switchover.

LED house light designers work around the issue of the narrow beam of a single LED, by building household LED light bulbs that are a collection of individual LEDs, with each diode aimed at a different angle, so that a wider area is highly illuminated. This increases the area of full light coverage of an LED light. However very few such bulbs provide the breadth of area coverage of existing incandescent bulbs or CFLs and at the same time are bright enough.

Where LED lights outshine existing bulbs is as replacements for lighting that is (or should be) highly directed. For example, a light in a narrow hallway, where the chief point of the light is to show people their way down the hall, would be a good application for LEDs.

Task lighting is another example of an application where LEDs shine. Why light up your entire work room if all you need to see is the tools on the work bench right before your eyes? A couple of LED bulbs hanging above the work area will do the trick nicely. But you can only cost-justify this in energy savings if you live half your life in the workroom.

LED light bulbs are, in theory at least, very durable, when compared to incandescent bulbs and compact fluorescent bulbs. LED bulb life ranges from 35,000 to 200,000 hours, compared to 1,000 hours for a good incandescent light, and 8,000 hours for a CFL. But I have seen many consumer ratings of LED bulbs that report burn-out within a few days of being switched on. Clearly there are some quality problems still to be worked on - yet another good reason for holding off a couple of years before switching wholesale to LEDs.

Whether LEDs will really live up to their long lasting billing remains to be seen - even the 35,000 hour ones would need to be on 24x7 for 4 years before they come close to reaching their advertised range. And LED lights do dim with age - so while a bulb might have a lifetime of 35,000 hours, it won't emit its starting light level for the full 35,000 hours - the older it gets, the less light it will emit. LED lights do decline progressively in light intensity and therefore in efficiency, although they will still be more efficient than either CFLs or incandescent bulbs throughout their life.

The "color temperature" of a light bulb, measured in 'degrees Kelvin', determines human visual response to its light. You are probably comfortable with the yellowish glow of incandescents at around 2800 Kelvin (2800K), even though fluorescent lighting is closer to the natural daylight temperature of 6000K. Any LED with a temperature of 6000K or higher will seem bluish, and any LED with a color temperature above 4000K will appear whiter than an incandescent bulb.

While homeowners are typically worried about how fluorescent or LED lights can make their rooms look blinding white instead of the comforting yellow glow provided by incandescent bulbs, you should remember that a little sacrifice in color temperature will put a big dent in your electricity bill

. Be a trend-setter, not a trend-follower - start converting your home lighting to true daylight colors, whether with CFL lights or LED light bulbs. You will be helping your family and friends to switch over, when they find out they won't be the only ones with a slightly bluer light hue in their homes.

Whether you switch a few of your lights to LED lights now, or let the technology and reliability improve, you can count on the fact that LEDs will play an increasing role in lighting our houses in the years ahead. I personally think it makes sense to wait, except in certain special lighting situations where the direct, high-color-temperature light of LEDs is what you're after, and where money is no object. If you just want to save money - or to cut your energy use for environmental reasons - an equal amount of money spent on CFLs, or most other energy efficiency upgrades, will cut your energy bills and carbon footprint more than buying the LED lights now available.

Kitchen lighting

Wind Turbines??

Wind turbines? Dontcha hate them! Horrible things going round-and-round. Roundandroundandroundandround. They make a lot of noise, and bits seem to keep on falling off them. Dangerous.

Then there’s the NIMBY neighbours: “Oh, we don’t want one of those here,” they say. “Renewable energy: yes. Somewhere where it’s inconvenient: NO!” It’s as though they think a wind-energy solution can be integrated into every house with minimal visual impact.

Well blow me down, it can!!

Ridgeblade is a fabulous wind-turbine solution from UK based The Power Collective. It’s very simple: instead of a large standalone windmill-like structure, put a long bladed turbine along the ridge of a building’s roof.

The blades are about the same length as a medium wind turbine, so you can catch about the same amount of wind. What’s more, as these can be mounted along an existing roof, there’s no need for an additional NIMBY-provoking superstructure.

So revolutionary is this approach that the company has won $750,000 from the Green Challenge Awards.

“It’s beyond a dream,” said Power Collective CEO Dean Gregory when Skype founder Niklas Zennström announced him as the winner. I’ll bet: he’d only entered the competition two days before the closing date!

This is the right kind of innovation, one which will bring a community together to provide energy together on a collective scale, rather than relying upon some far away power station to provide the same for a profit.

Let’s hope it succeeds.

Rediscover Energy Pennsylvania Information Center

New For Customers in the PPL Service Territory: Questions about what Rate Cap Expiration means to you and your business? Click here to watch WITF-TV's "Caps Off" program that provides advice and information regarding the elimination of electricity rate caps on January 1, 2010 in the PPL service territory. (Note: You will need Apple QuickTime player to watch the video; you can download it here.)

In today’s marketplace, making an informed buying decision about your business’ electricity needs is made complex by the sheer number of cost components that constitute your total energy price. It doesn’t help matters that these 15-20 components are referred to by an “alphabet soup” of acronyms.

GDF SUEZ wants to help simplify things by consolidating these components into two broad cost categories that are driven by distinctly different determinants:

1.) Energy
The output of a generator + losses and congestion
Majority of total energy cost
Highly volatile, but also highly liquid
Determined by market forces

2.) Delivery
The cost of getting energy from generator to meter
Smaller portion of total energy cost
Low volatility, but not very liquid
Determined predominantly by regulatory bodies and ISO’s

How to Change a bulb in a recessed light.

Here is video showing how to remove a trim of a 5 inch recessed light fixture to replace a light bulb. It may sound like a silly topic but for many home owners this bit of knowledge is not intuitive. Some recessed light are just difficult to open even for trained electricians. We have many clients here in Philadelphia that will schedule whole hose bulb replacement every two year. This may sound excessive but if your home has over 25 recessed light a complete bulb updating could save you time and energy. This has been a common practice in commercial building to lower maintenance issues. It also insures that the lighting in your home has an even color temperature.

Happy "OLD STUFF DAY" March 2

Old stuff is fun. That is in flee markets and Antique stores. You don't want your electrical system to be "OLD STUFF" Your main electrical service should be replaced every 30 years. The general house wiring should be updated at least every 60 years.

Give us a call if:

1. Your main safety box is older then 1980.
2. If your house wiring is older then 1950.

Old electric stuff is not made for today's electrical needs.

PECO's Electric System.


The Electric System

There are various components that are needed to create, transmit, and distribute electricity. The following graphic identifies and describes those various components.

#1 Electricity is generated at one of the many different power plants located throughout the region.
#2 Electricity travels from the power plant over high-voltage transmission lines to substations.
#3 At a substation, the electricity voltage is lowered so that it can travel over the distribution system.
#4 Transformers, both aerial and underground, reduce the electricity voltage even further so it can be accepted by the home or business.
#5 Service lines carry electricity to the home or business.

Touching Wires causes instant death-$200 fine

I have been working on a new electrical panel sticker. I think this one could be worded too strongly. I'm going to stick with the home owner tips instead. I don't think that electricians in Philadelphia are allowed to fine people for touching their electrical services boxed.
