Flickering refers to quick, sudden changes in a light fixture’s output over a short span of time, and can either be visible or invisible.

Hopefully, this guide helps to better identify any possible causes of LED light fixture flickering and potential solutions to address them.

The dome's upper attachment point is 61mm in diameter to fit most stereo microscopes and the base expands out to 160mm outside diameter to accommodate large specimens. The height of the dome measures 88mm and requires at least 95mm of vertical space for adequate clearance from the microscope stage. The power supply accepts input voltage from 96V-265VAC and features variable-intensity control and the 50,000 hour LED service life ensures years of trouble-free, energy-saving performance.

The new 120-LED OMLED-6WDRL dome ring light is a unique addition to our lineup of accessory lighting. It creates a diffused and UV-free dome of cool white 6000K-7000K light for imaging specimens which would otherwise suffer from over exposure under standard lighting. Diffused illumination also brings out more surface artifacts and details which wash out under normal conditions, making it ideal for gem classification, QA inspections, PCB repair, jewelry manufacturing and more. In addition, the ring light and power source are ESD-safe and work well in static-free environments where delicate electrical components are being handled.

Invisible flickering is flickering that is not easily recognizable to the human eye, but can still cause issues such as dizziness and migraines.

Visible flickering is flickering that can be seen, and has been associated with seizures and other health hazards due to the rapid changes in light, in addition to safety issues on roadways and parking lots.

Using higher quality constant current LED drivers will help to eliminate power current peaks and flickering as a result.

The driver acts as the main power supply for LED lights, and any issues such as heat over time may cause fluctuations in the DC voltage, which will lead to the light source flickering.

As lighting technology becomes more advanced and LED lighting becomes more readily available, it’s important to be aware of new issues to tackle as the technology changes.

LED lighting is more energy efficient and has a much longer lifespan than traditional forms of lighting, but one common issue that can be experienced with LED lighting is flickering.

Another major cause of flickering is having fixtures that are set up with incompatible dimmer switches. Some dimmer switches operate in such a way that the power to the bulb goes on and off several times per second, which are not compatible with LED lights, and would need to be replaced with a dimmer that is compatible with the light.

While LED lighting has come a long way and are generally more reliable over time compared to traditional forms of lighting, there will still be differences in quality between LED fixtures. Lower quality LED bulbs use lower quality drivers, and are more likely to be affected by flickering issues over time when compared to higher quality ones. While lower in cost in the short term, the maintenance required by a lower quality light may actually end up costing more in the long run.

This difference in quality will also influence how a higher power load will affect the driver over time. Better drivers will help to normalize the output better than a lower quality driver. Repeated surges can also wear down drivers over time and cause flickering and premature failure.

Another potential cause for LED light fixture flickering is loose wiring or a loose bulb. Any burnt or loose connectors and circuits can cause LED lights to flicker. This may be the result of improper installation, or if many fixtures are flickering at the same time, then there could be a problem at the panel or the junction point to be addressed.

Also being sure to address any changes during the wiring installation to your voltage and the power load will help to prevent overloading your fixtures and any resulting flickering.If there aren’t any issues with the driver or the voltage, then it is possible that a component in the fixture is malfunctioning prematurely.
