Although any light will help alleviate the strain on your eyes while looking at a screen, there is a right and wrong type and location for the light to have the best effect. As mentioned earlier, bias lighting is placed behind your screen to establish a brighter field of view so that your eyes aren’t constantly trying to find a balance between light and dark. Bias lighting illuminates a room without creating glare or reflections on your screen, shining directly in your eyes, or affecting how you see contrast and colors. Other sources of light, such as ceiling lights or lamps, can do all of the above.

If light is shining onto your screen, there’s going to be a noticeable difference in how the picture appears. Colors won’t be as vivid, and the screen might be hazy. In an attempt to remedy the situation, you could adjust the brightness and contrast. However, these adjustments will decrease the life span of the bulb or LEDs in your screen. The adjustments will also result in increased energy consumption along with a higher electric bill.

Adding light behind your screen instead of in front of it will eliminate any color or contrast issues. Dark scenes or colors will look richer against a white illuminated background. The picture below demonstrates how dark colors are lost against a dark background.

howtogeek.com, “. . .  you want a bulb temperature that is as close as possible (if not identical) to the reference point used in the industry that both manufactures the screens you’re looking at as well as creates content for said screens and that’s 6500K.” He goes on to say that, “The bulbs (be they CFL or LED) inside your HDTV or monitor are calibrated to 6500K, the film and digital video shot is color corrected to have a 6500K white reference point, and the editing suites where content is edited and worked on have 6500K bias light.”

So what exactly does 6500K mean? Correlated color temperature (CRI). CRI refers to how accurately a light source reveals the true colors of objects, people, and surroundings and involves a distinct testing method with comparisons to incandescent light or daylight. A light source with a CRI close to 100 shows colors very similarly to how daylight or incandescent light shows those same colors. To get the best picture, you’ll want bias lighting with a CRI as close as possible to 100.

We carry LED strip lights that are great TV backlighting options and will help you achieve the best picture on your screen.

Our variable color temperature controller and remote. The strip also has a CRI of 91, which will show screen colors accurately. This strip can be purchased in 3.28- or 16.4-foot lengths that can be cut and connected where needed with strip light connectors.

Another great option is our 6500K LED strip with LC2 connector. It has a CRI of 79 and is available in 1.64-, 3.28-, and 16.4-foot lengths. The peel-and-stick strip can be cut and connected where needed with compatible strip light connectors.

A kit in cool white is also available and is a convenient bias lighting solution. It has a 6500K color temperature, 79 CRI, and includes everything needed for installation—power supply, dimmer, remote, connectors, etc.

The strip lights listed above have peel-and-stick adhesive backings and can be cut or ordered in lengths to fit every screen size; strips are marked with designated cut lines. If you don’t order a kit, you will need a power supply and can purchase a controller with remote for dimming.

An easy installation method is to use a continuous length of strip around the back of your screen. For a cleaner look, you can cut the strips at all four corners of your screen. If you plan on cutting your LED strip lights, you will need 4 connectors (already included with the kit). All compatible installation supplies will be listed under the accessories tab on each product page. The following instructions explain how to install LED strip lights by cutting them into sections. Note that installation methods will differ depending on the strip you choose.

1. Cut your LED strip lights into lengths that fit the back of your screen. Because we offer different lengths, you might be able to order separate strips that will fit all four sides of your screen.

To most people, circuit panels are the first place they go when power fails to a room.  The loud click heard when a space heater or hair dryer overloads a circuit usually calls for a quick trip to flip a circuit breaker back on.  Every building depends on the circuit panel for safety and electrical management for the home.  The electrical panel for your home, along with the attached circuit breaker, serves to delegate power throughout the home.  By splitting up power demands, it prevents overloads in separate rooms and isolates individual features and appliances.

You may be wondering why we need to split up circuits the way we do.  If all of our devices operate on 120 volts, why do we need separate circuits?  The answer has to do with the physical quirks of wiring.  You see, while everything operates off of the 120 volts delivered by your home’s wiring, the power demands are different for each device.  As power is applied to a circuit, current flows over the wiring and heats it up.  The higher your power demands, the more current is flowing through the wires.

The wires in your home can only handle a set amount of current (most circuits are 20-amp circuits) before they overheat and begin to ignite insulation around them.  If you placed every light, appliance, and TV in your home on the same electrical circuit, you’d reach this thermal limit almost immediately.  To prevent his, we install circuit breakers to help separate energy demands to specific rooms.  We also separate the energy load to create special appliance circuits.  This is why your HVAC unit is on a separate circuit from your kitchen and your laundry room.  Appliance circuits use thicker wires which are designed to handle higher electrical loads.  High current circuits are expensive, so homes are designed to use them sparingly.

This is also why you should only ever replace breakers and fuses with new units that have the same tolerance.  Circuit breakers are designed to be the weakest link in a system.  They must trip before anything on the circuit itself would fail.  This safety feature means that the breaker will trip before wiring overheats or appliances are damaged by high-current draw.  If you do need to replace a breaker, always match it with the same current-rating.

Power surges are another reason we separate circuits in a home.  Whenever a load is applied to the system (you turn on a hair dryer, electrical appliance, or even a lamp) inrush current is also applied.  Inrush-current is the initial surge of power that occurs when current is increased.  Extra power is applied across the system, which causes a risk of electrical damage when a high-power device is applied to a low-power circuits.  To mitigate this, high-load motors such as those in power tools, HVAC systems, and other appliances are plugged into special appliance circuits.  This is also why you should plug sensitive low-voltage electronics into surge protectors.

Sometimes electrical panels can wear out.  While the signs are clear when you know what to look for, without experience you have no way of knowing if it’s time to replace your panel.  Get an inspection for your electrical panel if:

If, however, you happen to notice one of two logos, Federal Pacific Electric (FPE) or Zinsco, you should call for a replacement immediately.  These older models of electrical panels are unsafe and should be replaced quickly.

A Timeless StyleIn the post-Victorian era, brass chandeliers shimmered with crystal drops and porcelain lamps were embellished with colorful floral themes. For members of the British aristocracy, the early 20th century was a time of elegance, luxury and opulence.

A quick glance through the latest designer catalogs are ample evidence that the decor of previous eras are still hugely popular. The style can easily be recreated with antique brass desk lamps. In contemporary homes, an elegantly crafted modern light fixture can give you the look of the most treasured antique.

An electrical emergency can cover a number of different situations. If the emergency is someone suffering from a severe electrical shock, you need to call 9-1-1 immediately for an ambulance. In this post we will deal with other types of electrical emergencies you may encounter in your home, such as sparking and power outages.

One piece of advice should stand atop everything else: call for the assistance of professional electricians when it comes to emergency repairs. You should never tamper with an electrical system on your own in an attempt to fix a problem, no matter how urgent it seems. The danger of electrocution or fire is high, and you cannot take the risk.

Electrical fires are one of the more common ways that house fires start. If exposed wires, an electrical short, or a malfunctioning appliance triggers a fire, do not throw water on the flames. If an appliance is on fire, disconnect it from its power source if possible or shut down the power. Use a fire extinguisher if you have one. (If you don’t currently have an extinguisher in the house, put it on your immediate “to-do” list.) Call 9-1-1 if the fire continues. You will need to call electricians after the immediate danger is over to track down the cause of the fire and discover what repairs and new installations are necessary to prevent it from reoccurring.

A power outage may come from the municipal grid, or it may be the result of issues with the electrical system in your home. If only your home is experiencing a black out, first check the circuit breaker panel to see if any tripped breakers are at fault. Then call for licensed electricians to look into the possible causes.

A power surge from a lightning strike or downed power line can cause damage to appliances, take out the power, or trigger an electrical fire. If this occurs in your home, you should consider contracting professional electricians to install a whole-house surge protector in the electrical panel so you will have few worries in the future.

Always remember, call emergency services first in the case of imminent danger such as fires or electricity. Once the immediate threat has ended, look to licensed electricians for repairs and other services that will prevent further problems and keep your home safe.

One of the limitations of some grid-tied photovoltaic systems is that the owner will only benefit as long as there is sunlight while the grid is functioning. Otherwise, if there is an outage, they may not even use the energy they are generating from the rooftop. During such times when the grid is disconnected, the owner can neither use the rooftop solar nor export the energy to the grid.

Owners of PV systems without backup functionalities can upgrade by adding AC coupling. This enables them to store energy and use it anytime, including during emergencies and grid outages. The AC coupling converts a simple grid-tied system into a Grid/hybrid or grid interactive system. This provides grid-ties savings whenever the grid is up and running, and off-grid independence, as well as security when there is a utility outage.

The main components of AC coupling include an energy storage system, a grid-interactive inverter/charger, a coupling device and the second panel with additional wiring for the critical loads to supply during outages.

Battery storage enables better power management by providing a number of benefits which include:
