The living room seems a little dim, you think. Here’s the DIY solution you cook up: you head over to the hardware store, buy a brighter bulb, screw it into the nearest lamp and bask in the incandescent glow. Easy, right?Not exactly. Using a lightbulb with higher-than-recommended wattage for a specific fixture is known as overlamping. This seemingly innocent practice is actually surprisingly dangerous, and is one of the leading causes of house fires in the United States — right up there with candles, smoking and cooking mishaps.

Overlamping is one of the most commonly overlooked mistakes a homeowner can make, and it can be deadly. A 2011 electrical fire that killed 11 people in Brisbane — the according to home improvement blogger Taryn Williford. When you place an incandescent bulb with wattage that’s too high in the socket of a lamp that cannot provide the required electrical output, the ensuing heat and intensity of the bulb can scorch or melt the socket and the insulation of the lamp's wiring.  

Now you have prime conditions for arc fault. An arc fault occurs when a spark jumps through the air between exposed wires. This sounds dangerous, yes? It is — in fact, the National Fire Protection Agency and the National Association of State Fire Marshals electrical power. A CFL often has a tubular shape atop the familiar screw-bottom.

An LED (light-emitting diode) light is directional, rather than radiant. This allows the LED to use much less energy than an incandescent light or even a CFL. LEDs can also directly replace incandescent bulbs in some cases.

CFLs use a much lower wattage than incandescent bulbs and create far less heat, making overlamping situations far less likely. LEDs also use much less electricity and even remain cool to the touch. The risks of overlamping are negligible.

There are drawbacks to any lighting solution. Incandescent (even halogen) lights are energy inefficient. CFLs are made from materials that are terrible for the environment. LEDs burn out at a quicker rate. The right light for you is the light that makes you most comfortable in your home — and that’s a decision you need to make.

If you’re in need of an electric panel installation, you might be wondering if you can do it on your own. Even if you’re a handy kind of person, handling it on your own is not a good idea. In fact, many cities have a rule in place that prevents any non-professionals from performing this kind of installation.

Beyond the complicated nature of putting in a new electrical panel, the task can be dangerous. This is in addition to the long-term hazards that might arise from incorrect electric panel installation. You could be putting your home at risk of a fire, in addition to exposing yourself to the possibility of electrocution.

If your panel’s wiring is outdated or improperly installed, you might be facing many difficulties. In addition to inconveniences like not being able to add new circuits to your system, an inferior panel could leave you dealing with added expenses and even dangerous conditions. Some of the reasons for upgrading or replacing your existing electric panel include:

constant-current LED driver or constant-current driver is used to regulate the amount of current that is supplied to an LED or LED array to maximize LED lifetime. If current is not regulated, LED brightness can fluctuate and life span can be shortened. The constant-current driver is used for LEDs or light fixtures that require a stable output current and operate within a range of voltages. Most finished LED products already have a constant-current driver or resistors to regulate current. If you’re building an LED fixture or replacing a constant-current driver, it’s important to verify that the output current and voltage of the driver is compatible with the LEDs’ current and voltage. If your LED product already has a constant-current driver or uses resistors in the LED array, you might need a constant-voltage power supply.

If your LEDs are dimmable and you want to change their brightness, choose a Magnitude Dimmable Power Supplies. These dimmable power supplies work by varying the power on the AC input side of the power supply by means of a TRIAC dimmer. This change in power on the AC input side will vary the voltage on the DC output side and control the intensity of the LEDs. TRIAC dimmers are common hardware store and household dimmers, which include brand names such as Lutron and Leviton.

Pulse-Width Modulation Dimming: Pulse-width modulation (PWM) dimming can be used to control dimmable power supplies such as Mean Well LPF Series. This type of dimming control adjusts the output current based on the duty cycle. As the duty cycle increases, current will increase and the LEDs will be brighter. Conversely, if the duty cycle decreases, the current will decrease and the LEDs will be dimmer. Pulse-width modulation for these drivers is based on a 10-volt signal level with a frequency between 100Hz-3KHz. The MLD-5A are compatible for this application.

Resistive Dimming: Resistive dimming can be used to control dimmable power supplies such as 12-Volt Mean Well HLG-40-240 Series or 12-Volt Mean Well HLG-600 Series or here.

The efficiency of a power supply or driver indicates the percentage of power that goes toward making your LED product function. An efficiency of 80 percent or higher is recommended for operating LEDs. 

When choosing a driver or power supply, the size of an LED product’s housing or area of installation is important. If you wish to put a constant-current LED driver inside of a product, the driver must be small enough to fit in the product’s housing. Similarly, if the driver or power supply is used outside of the product’s housing, it should fit the area of installation. Drivers and power supplies are available in a variety of sizes to suit your needs.

A Class 2 driver or power supply is in accordance with limited power levels defined by the National Electric Code (NEC) and fulfills the requirements of Standard UL 1310. Output is limited to 60 volts DC and 100 watts. Because power sources with this rating have limited output, it might not be possible to power as many LEDs or lights as those that don’t have a Class 2 rating. However, these power supplies and drivers provide protection from fire and electric shock.

A Class II rating refers to a double insulation layer between AC input and DC output wires. These drivers and power supplies do not require a ground connection.

1-by-4-foot,  LED light panels use Even-Glow® technology and diffused optical lenses to deliver smooth, flawless illumination without visible bulbs or hot spots. They can be recessed mounted or surface mounted to an existing ceiling junction box. The LED fixtures emit up to 4,600 lumens of natural white illumination for home lighting, kitchen lighting, living room lighting, office lighting, basement lighting, sign backlighting, hospital lighting, and more.

LEDs in the panel lights are designed to last five times longer than fluorescent tube light bulbs without the notorious hum or flicker they produce. Each LED panel light has a slim, white aluminum alloy frame and an internal 0-10-volt dimmable constant-current driver. Dimming can be achieved with a 0-10-volt switch or by using the light’s power-cycle feature to activate set brightness levels. The energy-efficient panel lights operate within a 100-277V AC range.

Electrical pre-construction services are a portion of the pre-construction services that are undertaken when a house is to be built. Pre-construction is considered a part of construction management in which specific elements of a project are planned out and coordinated between different contractors. The end goal of pre-construction is to create, implement and complete a project that will best satisfy the needs of the owner.

So why do contractors undertake pre-construction during the process of building a home? There are really two reasons, both of which have to do with ensuring a safe, orderly build that meets the owner’s expectations.

If you have ever watched a cartoon or old TV comedy where the characters are attempting – and failing – to build a house or skyscraper, then you know how important pre-construction planning is to a building project. Pre-construction ensures all contractors are on the same page with regards to the project itself. This permits the project to be completed in a much smoother fashion. It also ensures the safety of all workers involved with the project.

For example, electricians doing risky high-voltage work on the house’s wiring systems can warn other workers to keep their distance. This helps prevent electric shock or fire due to contact with potentially live wires. They can also avoid using certain tools to minimize the risk of damaging the electrical system.

Pre-construction work also ensures the owner’s wishes will be followed as closely as possible. Have you ever seen a home remodeling program on TV where the owners are trying to fix a botched remodel? Much of that hassle can be prevented with better communication. This way the owner’s specifications are met. If there are issues meeting the owner’s needs with the current plans, then their input needs to be sought. This way new plans can be developed to meet their needs.

Electrical pre-construction services are very similar to the pre-construction services provided by other contractors. The process works to save the owner money now and in the long run. These steps may vary depending on the contractor, but usually include the following:

If you have ever attempted to do your own electrical work at home, you know the value of a good electrician. The same goes when you’re having a home built or remodeled. Good electrical pre-construction allows you to save both time and money. A solid pre-construction plan will give you the electrical layout you require. That’s especially important if you plan to utilize solar or other alternative energy sources. It will also help you evaluate your choices and choose equipment that will be the most cost-effective over the years.
