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.

Who doesn’t love recessed lighting? It is never out of style to have lighting subtly tucked into the ceiling, leading many homeowners to use recessed lighting in numerous rooms. We love recessed lighting at Electrical Gurus, and have installed plenty of them for Des Moines home and business owners over the years; however, there are instances when recessed lighting isn’t enough on its own or should be avoided altogether. Your local electricians are here to share when you should consider reining in your recessed lighting.

Providing a space with ambient lighting, as shown in our previous blog, is a crucial component when creating inviting, warm and properly illuminated spaces in your home. Too much of a good thing is definitely possible with recessed lighting, and it should never be used in place of all other light sources. Not only will your spaces lack task lighting, but you will be effectively illuminating your space from directly above, requiring far more light (and energy) to brighten the space; odds are, even with the lights cranked up, you’ll still have a dull, cavelike look to walls and corners with only directly downward light. Accent your recessed lighting with outward or upward ambient or accent lighting to create a more balanced lighting display.

Often, we see a single recessed light over a vanity, which can lead to a displeasing lighting effect. Just as with your home’s furniture, using only a direct overhead light creates unsightly shadows and does not properly illuminate the face. Using an overhead light on your vanity is great, but should always be accompanied by frontward facing lights to properly see your face.

Placing recessed lighting in tall ceilings is an odd concept. The primary benefit that recessed lighting provides is space efficiency, as the cans are placed above the ceiling, hiding the house wiring and electrical components. In a tall ceiling, not only is this unnecessary, but the light has to start from an even higher point. By the time the light reaches the room below, it is spread out and weaker, leading homeowners to use far more energy to brighten their rooms. Additionally, the shadows around the lighting cans will be especially prominent, leading to an ultimately darkened room. Instead, utilize hanging lights, fixtures, wall-mounted sconces, or even ground level lamps to brighten your taller rooms.

While it may sound like we’re beating up on recessed lighting, that is only because it is one of the most versatile lighting sources, which leads people to incorrectly believe that it is perfect in any room or as the only light source. As part of a comprehensive lighting strategy, recessed lighting is nearly unmatched in its widespread application and ease-of-use, just be sure to remember these helpful tips from your friendly, local Des Moines electricians at Electrical Gurus.

LED light bulbs and fixtures are the best alternatives for many reasons.

LED lights are available in several shades of white. These shades are referred to as a bulb’s correlated color temperature (National Institute of General Medical Sciences, states that, “Circadian rhythms are physical, mental and behavioral changes that follow a roughly 24-hour cycle, responding primarily to light and darkness in an organism’s environment.”

According to writes, “Several studies have documented the importance of light in reducing depression, decreasing fatigue, improving alertness, modulating circadian rhythms, and treating conditions such as hyperbilirubinemia among infants. Further, the presence of windows in the workplace and access to daylight have been linked with increased satisfaction with the work environment.” Windows are the best method of accessing daylight, but cool white LED lights along with the right color temperatures at the right times, can have the same effect on the body.

Warmer color temperatures lead to the release of melatonin, which causes drowsiness. This is appropriate during bedtime hours, but causes problems for those who need to stay awake, such as overnight nurses and doctors. Introducing natural or cool white light to hallways, operating rooms, and nurse stations can help hospital staff, especially overnight workers, feel more alert and energetic.

EPA has a list of cleanup procedures, such as having everyone leave the room, opening a doors or windows, shutting off heat and air-conditioning systems, and other specific instructions.

Fluorescent and incandescent bulbs also emit low doses of UV radiation that can damage not only facility materials but can also damage skin and eyes. According to a CBSLA.com discusses the results of another study that had similar findings. In this article, it is said that, “. . . exposure to the (fluorescent) bulbs could lead to premature aging and cancer.”

Continued UV exposure is also harmful to the eyes. A LED lights won’t flicker or emit any color spikes. Color fluctuations and flicker can cause negative effects, such as headaches and dizziness. When used for hospital lighting, LED bulbs and fixtures can improve overall health and eliminate the possibility of additional health risks posed by fluorescent and incandescent bulbs.

Seeing colors as they truly are is critical in health care environments. Inaccurate color rendering of skin or blood could lead to a misdiagnosis or failure to see signs of infection or jaundice. The spectral graph below can be helpful in understanding the advantage of high-CRI light sources. Lights with a low CRI will show fewer colors while high-CRI lights cover more of the spectrum. A light source’s ability to show more colors increases its accuracy in revealing the true colors of people, objects, and surroundings.

FreemanWhite, a health-care-focused design firm reports, “. . .light fixtures with a high CRI . . .  help caregivers assess rashes, lesions, and skin pigmentation.” They go on to say, “In the interest of avoiding liability claims, better lighting quality can enhance a caregiver’s ability to diagnose correctly, identify reactions, prevent secondary infections, and minimize readmissions.” High-CRI LED lights can also help prevent medication errors.

Another method of LED hospital lighting control is the use of occupancy sensors. These sensors will save money beyond those that result from reduced energy consumption. Sensors will also extend the life span of bulbs and fixtures even further by turning them off when no one is in the area. These sensors are best suited for low-traffic areas.
