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.…
May 4, 2018 Outdoor Lighting
Homeowners have a myriad of lighting options for illuminating fences, walls and perimeters. Such lamps serve important purposes, marking the boundaries of the location and providing guidance for various activities in the outdoor sections of the space. For security, fence led lighting lights up dark and isolated parts of the lot, including corners and fencing behind trees or bushes.
Wall Pack LED Lights
Wall pack LED lights are an ideal solution for perimeter lighting around homes. The permanent fixtures are versatile, allowing individuals to use them on fences or the wall of the house. As a non-intrusive lamp, the units are not bulky and offer space-saving benefits. They are also less prone to light spillage and trespass, as the beams are pointed upwards (or downwards, depending on one’s preferences).
Aesthetically, wall pack LED fixtures provide adequate background lighting for several types of activities in backyards. Low color temperature options create a soft and comfortable environment. For automated operation, it is possible to connect a day/night or motion sensor to the lights.
LED Pole Lights
Some homes do not have fences. In such situations, it would not be possible to setup wall pack lights for perimeter lighting. Instead, one may opt to install LED pole lights. The units are effective for marking large spaces.
There are numerous types of outdoor LED spotlights that can be mounted on poles. An LED spotlight or floodlight is suitable for general illumination in the area. Cut-off shields around the light head may improve beam configuration and direction. Like wall pack LED lights, the fixtures are also compatible with day/night or motion sensors.
For security applications, individuals should consider installing a compact camera at the top of the pole for monitoring the space. Supplementing the system with infrared LED lights may improve visibility during nighttime surveillance and monitoring.…
