LEDs can sometimes be prone to flickering. Although all luminaries (technically) rapidly flicker during light generation, LEDs are associated with this issue more often than other types of lighting technologies. This article will address how to fix flickering LED lights.
LED Bulb or LED Driver?
Contrary to popular belief, flickering in LED fixtures is mainly caused by fluctuations in current flow or dimming functionality. LED bulbs or chips are known to be extremely durable and reliable. With this in mind, replacing the LED bulb may not always fix the concern. In the case of dimming, the power supply must be toggled quickly to create the desired effect in LED lamps.
By comparison, filament-based fixtures rely on a heating and cooling mechanism to generate dimming.
For LEDs, an incompatible dimmer could be the culprit. To address this, one should make sure the dimming component is designed to work with the specific LED light. Furthermore, the LED fixture should be capable of dimming, as some variants are non-dimmable.
Achieving Constant Current
If lack of constant current is the concern, it is important to take a closer look at the LED power supply, which comes in the form of an LED driver. The lighting component converts AC voltage to DC voltage for electrical compatibility. A high-quality LED driver can make supply more consistent, resulting in the elimination of flicker.
When troubleshooting for the root cause of the concern, it is recommended to pay close attention to the rate of flickering. If the flickering is inconsistent, then the compatibility is likely the solution. On the other hand, if flickering is countable or displaying a rhythmic pattern, the concern is probably the power supply or LED driver.
Lastly, wiring and loose connections may also contribute to LED flicker. Before attempting to replace any parts in the system, one should double check the wires first to ensure proper connection.…

LED lamps are often promoted as energy-efficient lighting for both inside the home and outside however experts say that LED lighting, if not installed in moderation, could affect our health; this is because LED lights emit 10% more blue light and CFL lights. LED lighting leads to cost and energy savings and a lower reliance on fossil fuels in incandescent bulbs. An electric current passes through a wire filament until it becomes hot enough to emit light incandescent bulbs, therefore, waste a lot of energy as heat. A LED bulb produces light when positive and negative electrons move around within its semiconductor structure but not all LEDs are good for you.
Some Beneficial Effects of LED Lights
LED lights produce the same amount of light as incandescent or fluorescent bulbs but use less energy or watts this means they produce more lumens per watt. LED bulbs also have a longer rated life on average they will last over 20 years; to put this in perspective if you installed an LED bulb the same day a baby was born the bulb would not need to be replaced until after their college graduation.
Harmful Effects of LED Lighting
To determine if an LED light is good or not you have to know the color temperature. Color temperature is a measure of spectral content how much blue green yellow and red is in a light. A higher color temperature generally means more blue content while an incandescent bulb has a color temperature of 2400 kelvin containing fewer blue and more yellow and red wavelengths. A flame from wood or a candle burning has a color temperature of about 1800 Kelvin mostly yellow and red with almost no blue. Click here.
Blue-Rich LED Lighting
Blue-rich LED lighting can cause discomfort and glare this is because blue light scatters more in the human eye in yellow and red sufficient levels of blue light can damage the retina and LED light is concentrated which can cause severe glare resulting in strained eyes. The American Medical Association also warns the Blue-rich LED light can have a negative impact on the human circadian rhythm. Blue-rich LED light is estimated to be five times more effective at suppressing melatonin at night than the sodium lamps causing sleeplessness. Exposure to this type of light disrupts our body’s ability to produce melatonin a hormone that helps us fall asleep; when this process is disrupted our body’s clock goes off button. Many studies have suggested the blue light emitted by our mobile homes and laptops is destructive because its short wavelength tells our brain to stay a look.
On the other hand low light could be beneficial when it comes from the Sun as it gets diffused in the atmosphere and stimulates the retinal ganglion cells thereby improving the biorhythm. The United States Department of Energy has claimed that LED lights are no more harmful than any other lighting; however, we should ensure that lighting products meet photo-biological safety standards.

When setting up LED lights at home, individuals must choose various lighting designs and styles. For permanent fixtures, one of these components is the trim. By definition, this feature blends the lamp with the surface and provides illuminative properties (depending on type of trim). This article will help you select the correct trims for led lights.
Open and Reflector Lighting Trims For Led Lights
Reflector trims for lights consist of a smooth, shiny surface. This feature helps promote illumination and should not be used with extremely powerful fixtures. Open trims are standard components that protect the unit, which may also utilize a reflector component inside. Reflector and open trims are permanently fixed and do not offer adjustable features.
Eyeball and Gimbal Lighting Trims For Led Lights
For controlling light beams, eyeball or gimbal trims are recommended. These variants are equipped with a wide tilt range, from 30 degrees to 359 degrees. Traditionally, eyeball trims came into the market before gimbal trims. The latter option arrived to offer more freedom during installation, as the light head pivots within the housing. Suitable for space-saving configurations, gimbal trims can also be adjusted. However, at some angles the beam is prone to getting cut off by the housing.
Elbow trims, which offer similar tilt ranges, are an in-between option for adjustable lighting trims. For low-profile requirements, a slotted lighting trim can be applied to the system.
Baffle Lighting Trims
Baffle trims are designed to decrease the creation of glare inside rooms, making it ideal for home offices and bedrooms. This type of trim consists of small ridges around the component, which softens the beams as they make contact with the material. Baffles are commonly applied to recessed LED lights.
Lastly, it is important to point out that to ensure a smooth transition, the color of the trim should match the color of the ceiling. Decorative configurations may incorporate combinations of colors for accent lighting systems.

Boosting security inside residential homes can be streamlined using LED lights. In most cases, illumination at specific parts of the house can deter criminals and reduce the chances of unwanted burglaries.
Below takes a closer look at the role of LED lights in improving home security systems.
Motion-activated LED Lights
Leaving lights on in unoccupied rooms is a common practice, designed to notify outsiders about ongoing activities inside homes. Taking this practice on step further, motion-activated LED lights may also be used to provide the illusion of activity. Motion-activated LED fixtures also notify homeowners about unusual activity at night. A quick look at the lamps triggered by the motion sensor can instantly advise individuals about the location of the criminal.
Best places to setup motion-activated LED lamps include the following: front door, backyards, perimeters and dark locations. To avoid generating false positives, it is recommended to direct the motion sensor at sections that provide access to the home.
When going on vacation, individuals can choose to install day/night timers to generate lighting activity inside the home. Settings should include activation at sunset and deactivation at sunrise.
Infrared LED Lights and Cameras
These days, security cameras are readily available at mainstream stores. For complete, 24/7 protection, one should consider installing a day/night monitoring system. Such equipment features infrared LED lights, which allows the camera to capture images in low-light environments (at night). Modern security systems enable individuals to view multiple cameras under a single network from a remote location.
Homeowners may setup infrared LED security cameras at entry and exit points of the space. Additionally, some people prefer to mount such systems on poles, corners or roofs, for wide visuals of the space. Hiding the cameras from public viewing is not needed, as the presence of connected cameras may also help deter theft and criminals.…

LED spotlights have really become highly popular but there are some who truly don’t understand what they are buying! It can be very difficult to understand all the terminology associated with LED lighting because it can be made complex when buying a bulb. Some people are put off them because they don’t always understand them and it’s terrible. These lights are very simple and if you know a little more about them, they can be so easy to understand. If you want to know to how buy LED lighting, read on and find out a few common things you’ll run into when buying.
A Dimmable Light
Not all LED’s bulbs and lights work with dimmable light switches so you have to fully understand what it means. When you see a yes or no beside the dimmable section on the light box, then you know whether or not the bulb you’re buying is compatible with dimmable lamps or lights. This might not be a major thing to come across but if you want LED spotlights or LED bulbs which can specifically dim you have to know what you’re getting.
The Wattage Available
Wattage is a very simple spec and one which most will already know what it is but just in case you don’t, here’s a refresher. Wattage is quite simply the wattage of the bulb and how much power it has behind it. Does that matter? Yes, it does simply because some appliances require certain wattage of bulb so you have to ensure you buy the right wattage. Even with LED spotlights they have wattage and if you want to replace them, you need to understand what wattage to look for.

Lumens and Rate of Life (Rated Life)
The amount of light the bulb generates is called lumens and when you see that term, it’s quite simply referring to the amount of light being generated. However, this can be important, as can the rated life or rate of life notification. This is telling you how long the bulb is going to last before it starts to die out. Again, it’s important to know these things so that you can know how long the bulb will last. LED spotlights need the right bulbs and if the rate of life is short, it might not be as good as one which offers a longer life span.
Buying With Ease
If you want to buy LED spotlights or indeed any LED light, you have to first understand how much wattage you’ll need as well as know the overall shape and size of the bulb. Remember, there are lots of different shapes and sizes which might not fit into every lamp or light feature. You really need to measure these out carefully so that the right type of light can be found. Also, while you might find some LED bulbs costs a little more, they do last longer so the costs do work themselves out in the long-term.
Be More Energy Efficient
With LED, you can often find they can help you to save a little energy and still light up your home sufficiently too. Buying LED’s can be far easier and can often cost little in comparison to what you would have spent with non-LED bulbs. You can easily get the best LED’s and can use them for a long time. LED spotlights can be great but you do have to ensure the right replacement LED bulbs are found.

During bad weather, residential locations are prone to power outage. Such events usually come at the most inconvenient times, such as during periods of high activity around the home. Without light, productivity is negatively affected, forcing individuals to wait on the side for power to return. In order to prepare adequately for bad weather, which includes floods, torrential rain, storms, blizzards and icy conditions, one should consider picking up rechargeable LEDs products.
LED Flashlights and Lanterns
Rechargeable LED flashlights are a staple in emergency kits for homes. The handheld units are extremely durable and reliable. Individuals may also opt for an LED headlamp for a hands-free approach to emergency lighting. By strapping a compact LED light on, both hands become available for tasks around the space.
LEDs are ideal for this type of configuration, as the luminaries do not produce a lot of heat. You could have the LED headlamp on for hours without needing to turn the unit off to cool it down.
Rechargeable LED lanterns are great for standalone lighting. Individuals can easily carry the lamps around from one room to another. Furthermore, some handles can be attached on hooks, door knobs and ropes for temporary, general illumination in the home.
Rechargeable LED Light Towers
When an appliance or home system is destroyed by water or electrical surges, homeowners must make a careful assessment of the damage. In dark environments, this can be difficult to complete thoroughly.
As a solution, rechargeable LED light towers can help cast light over a wide space from a safe distance. Additionally, tall mounts, roughly 4-5 feet, may be useful for deploying lights over flooded parts of the home, such as the basement. Durable, waterproof LED light towers with caged fixtures for protection from rough contact are recommended for increased reliability during use.…

LEDs have a projected lifespan of 50,000+ hours, which supersedes most traditional lighting options available in the market today. This robust feature makes LEDs a top choice for residential homes and industrial facilities.
The lifespan of LEDs is affected my numerous factors, from design to environment. Below takes a closer look such factors.
Heat and LEDs
Heat is a leading cause for the deterioration of LED lighting systems. Because of this, a heat sink is typically installed with the unit to ensure proper cooling. Such components could be made out of ceramic or incorporate a passive cooling mechanism (for instance, horizontal fins). These features are effective when the LED fixture is positioned properly.
Incorrect mounting applications may amplify the accumulation of heat around LEDs. For example, a recessed LED lamp mounted on a low ceiling in a garage may cause the light to degrade at a faster rate, without proper protection. A solution to this issue would be to utilize an open mounting setup to allow air flow around the luminary.
When calculating the general lifespan of LED lights, it is important to take lumen maintenance into consideration. This term refers to the output of the LED lamp after a certain period of time. For instance, an LED lamp with an L50 rating refers to 50 percent of output after the unit’s intended lifespan. An L70 lumen maintenance rating provides 70 percent of output after the LED lamp’s estimated lifespan. Lumen maintenance ratings of LEDs are specifically useful for outdoor LEDs and for lighting systems with emergency applications.
Furthermore, high lumen maintenance ratings are ideal for parts of the home where detailed tasks are conducted, which can ensure optimized illumination before the light completely fails. LED fixtures in general locations do not need high lumen retention due to the presence of other lighting systems in the area.…

Several LED bulb designs available on the market today were adopted from traditional lighting standards, during the era of incandescent and halogen luminaries. For homeowners looking to switch over to LEDs, it is important to know about conventional bulb sizes, to ensure compatibility during installation. With this in mind, this article compares the differences between a LED PAR 30 and a BR 30 LED bulb.
Characteristics and Angles
A PAR 30 LED bulb provides spotlighting features, with tight angles lower than 45 degrees. The acronym ‘PAR’ stands for Parabolic Aluminized Reflector. These types of LED bulbs can be used indoors and outdoors, depending on the ratings of the unit. PAR LED products may be offered at various angles, such as: narrow spot, narrow flood or wide flood. These options range from 5-15 degrees to 45 degrees.
A BR 30 LED bulb offers the opposite lighting characteristics, compared to a PAR 30 LED bulb, in a sense that the angles are noticeably wider. This is easily distinguishable, based on the term ‘BR’ which stands for Bulged Reflector. This type of LED bulb provides lighting angles wider than 45 degrees.
Based on the lighting characteristics of the LED bulbs, we can determine their respective applications. PAR 30 LED units illuminate specific objects or targets, making them ideal for track lighting systems, illuminating landscapes, paintings and general security lighting. It is important to highlight that when the bulb is used outdoors, they must carry specific waterproof ratings.
A BR LED bulb is useful for lighting up wide spaces inside homes. Such objects and locations include living rooms, kitchens, hallways and doorways. To maximize the unit’s beam spread, it is recommended to use this type of LED bulb with recessed lighting configurations or with lighting guards, especially with BR LED bulbs that offer very wide lighting angles.…

LEDs are capable of superior illumination, which can be extremely powerful in homes and small spaces. To address such concerns, homeowners may choose to diffuse LED hot spots with acrylic or polycarbonate sheets.
Both options are effective in mitigating strong light beams and trespass, for softer lighting conditions. However, the materials vary greatly, when it comes to sturdiness, transmission and cost.
Acrylic vs Polycarbonate
Starting with acrylic, the material is a transparent plastic that is capable of withstanding rough impacts (shatter resistant). Comprised of a synthetic polymer of polymethyl methacrylate (PMMA), this type of sheet is sold under several names, such as Plexiglass and Optix. Acrylic sheets can be found on aquarium tanks and protective shield barriers in commercial skating venues.
Polycarbonate, on the other hand, offers another level of sturdiness and can withstand extreme impacts, vibration and dust (when sealed properly). With light transmission capabilities greater than 90 percent, the material is recommended for transparent lighting requirements over the target area.
Additionally, polycarbonate offers exceptional resistance to fluctuating temperatures. Such sheets have a threshold up to 120 °C, which is considerably higher than acrylic light diffusers.
Which One is Right for Me?
For homeowners, choosing between acrylic and polycarbonate sheet diffusers for LED spotlights highly depends on the application of the fixture. For outdoor spaces, polycarbonate sheets are recommended because of their durable features. Moreover, in outdoor environments, light diffusion requirements are usually minimal due to the wide space.
Indoor light diffusion can be achieved with acrylic sheets, due to their robust optical properties. The lightweight material does not lose its color easily, providing up to 10 years of transparent and reliable performance. Compared to other plastics in its group, acrylic is moldable, which allows lighting manufacturers to create covers that adhere to the form and design of the unit.…

Inside homes, hallways are tricky locations to get right when setting up lights. The spaces are extremely narrow, increasing the risk of glare and uneven beam distribution. LED lights present numerous viable solutions for hallways, due to their compact and reliable features. The units can take on unique configurations and settings, to make lighting systems in hallways more functional.
LED Track Lights and Wall Scones
Narrow hallways benefit from thin and long units, such as LED track lights or LED strip lights. Starting with the first option, LED track lights are fixtures mounted on a single-lane track, which is installed on the ceiling. Homeowners can add (or remove) as many lamps as they want on the track. Mounting LED lights above ground may help reduce tampering and direct contact, for individuals with kids or curious pets.
Moreover, the fixtures can be positioned individually to target hard-to-reach areas. This option is perfect for residential hallways with artwork and photos.
Recessed can lights may also be used for overhead lighting in hallways. This type of fixture only provides down-lighting features (no adjustable light head). An advantage to using recessed can luminaries is the application of cut-off shields for beam direction.
LED wall scones are also ideal for hallways. Unlike LED track lights, these units offer up or down lighting features. Because the fixtures take up space, they are usually found in wide hallways.
Recommendations for Installation
Hanging LED lights in hallways are not recommended for spaces with short ceilings. Surprisingly, this is practice is common in older homes that use chandeliers. Hanging LED fixtures are notorious for creating glare and may present some issues for tall individuals.
If the hallway leads to a staircase, it makes sense to provide additional lighting at the transition from the ground to the first few steps. For illuminating dark corners, homeowners may apply table lamps or tall lamps on stands.…
