Are you noticing that your plant grow lights are flickering? It can be a frustrating experience, and it’s important to understand why it’s happening so you can fix the issue.
Grow lights will flicker when there are fluctuations in incoming voltages, it’s connected to an overloaded circuit, there is loose wiring, or the driver itself is faulty.
An inconsistent light source can affect photosynthesis, directly affecting the plant’s overall health.
In this article, we’ll discuss the causes of LED flicker in grow lights and how to prevent it. We’ll also explain how flickering light could affect your plants and when you should replace your grow lights.
What Causes Grow Lights to Flicker?
You may be wondering why your LED grow lights are flickering.
It could be due to under-voltage, loose wiring, or having the grow lights on the same circuit as other appliances, and in many cases, other lights at home will also be flickering if they share a common source of power.
A faulty LED light driver or an inferior product could also cause changes in the lighting pattern.
We will discuss each of these possibilities in more detail.
Under Voltage
When the voltage supplied to an LED is too low, it’ll flicker like a firefly in the dark–dim and unsteady. This phenomenon is called ‘under voltage’ and can be caused by factors such as power surges, inadequate wiring, or a faulty driver.
If your grow lights are flickering, it’s most likely due to under-voltage. Under-voltage can cause more than just flickering; it can also affect the lifespan of your LED grow light.
When the voltage supplied is too low for an extended period of time, your grow light will have a shorter life than if it was operating on its ideal voltage range.
Fortunately, there are ways to prevent this: use surge protectors and ensure that wires are connected correctly and securely throughout the system.
You should also ensure you’re using an appropriate driver for your LEDs; drivers that are too powerful or weak can cause significant damage to your system over time.
Faulty LED Light Driver
A faulty LED light driver can significantly damage a lighting system, potentially leading to reduced longevity and unsteady illumination.
An LED light driver is used to regulate the power that’s delivered to the LEDs, ensuring they operate correctly and safely.
If it fails or is working improperly, you’ll experience flickering of your plant grow lights.
This can be caused by power fluctuations, voltage spikes or drops that are too large for the driver to compensate for, sudden changes in current draw from other devices on the same circuit, failure of components within the driver itself, worn-out capacitors or transistors, and bad connections between components.
When this happens, you should replace your LED light driver as soon as possible to avoid further damage and ensure optimal performance of your plant grow lights.
Grow lights on the Same Circuit as Other Appliances
If your horticultural illumination is experiencing any jitters, it could be due to other electricals on the same line.
Having multiple appliances and grow lights on the same circuit can cause flickering in your plant grow light.
This can happen because the current draw of the other appliances is momentarily taking up more power than what’s available, so when the current draw drops again, there isn’t enough to maintain a steady flow through the LEDs.
To ensure consistent lighting for your plants, make sure all of your grow lights are connected to their dedicated circuit and that they aren’t shared with any other appliances or devices.
If you have multiple circuits in use, it’s also a good idea to stagger them so that each appliance has its own separate timeslot for drawing power. That way, you won’t experience any issues with flickering or dimming!
Loose Wiring
Loose wiring can cause your horticultural illumination to act up, resulting in unsteady lighting for your plants.
If wires are not securely attached to the light fixture or the power source, then it could lead to flickering or dimming of the grow light when other appliances are also running on the same circuit.
Loose connections can prevent a steady flow of electricity from reaching the bulb and thus cause an intermittent glow.
To ensure that your plants get consistent lighting, check all wiring connections and ensure they are secure and snugly fit at both ends.
Furthermore, use quality electrical connectors and if you’re unsure about any part of the installation process, hire a professional electrician to do it for you – it’s worth having peace of mind knowing that everything is connected safely and correctly.
Inferior product
You don’t want to skimp on quality regarding your horticultural illumination, or else you’ll be left in the dark. Plant grow lights that are of an inferior product can lead to flickering and other unwanted issues.
Here’s why:
- LED drivers need to be designed for the specific purpose of providing power and current control for LEDs.
- Poorly made LED drivers may not be able to regulate current output which can result in flicker properly.
- Inferior components such as capacitors, resistors, voltage regulators, etc could all contribute to flicker due to their inability to meet required standards/specifications.
- Poor design choices regarding thermal management may also cause flickering as heat build-up can cause components not to function correctly, leading to inconsistent output.
- Low-quality LEDs themselves are prone to failure after a short period due to their lower level of resistance against voltage spikes and drops or even heat dissipation problems leading again to flickering.
You must only use high-quality parts when assembling your plant grow light system if you want it to work optimally and free from any unwanted issues like flickering!
Will Flickering Light Affect Plants
When it comes to your plants, you may be wondering if that flickering light could affect them in any way. The answer is yes, it can.
Flickering light can cause stress to the plant’s photosynthesis process, which can lead to stunted growth and a decrease in overall health.
An inconsistent light source also interferes with the plants’ ability to absorb nutrients from its environment, leading to deficiencies that can further inhibit growth and development.
Additionally, the constant changes in the intensity of the light can cause damage to the plant’s cells over time.
Fortunately, modern LED drivers are designed specifically for this purpose and reduce or eliminate flicker altogether, so you don’t have to worry about these issues affecting your precious plants!
How to Stop Grow Lights From Flickering
Now that you know the potential effects of flickering light on plants, it’s time to learn how to stop grow lights from flickering.
Here are five easy steps for preventing and eliminating flicker in your plant-growing setup:
Use a quality LED driver
A quality LED driver is designed to power LEDs and prevent them from switching on/off rapidly. Make sure to purchase a driver with the right wattage for your needs.
Invest in dimmable fixtures.
Dimmable fixtures give you more control over the brightness of your lights and help reduce flicker.
Utilize Pulse Width Modulation (PWM) – PWM allows you to adjust the voltage of your lights, which helps minimize any perceived flicker.
Select lower CRI bulbs
Bulbs with a higher Color Rendering Index (CRI) tend to flicker more than those with lower ratings. Consider using bulbs with lower CRI ratings for optimal results.
Choose an appropriate frequency
The frequency of your lighting system should be compatible with whatever type of driver or fixture you’re using. If possible, opt for a model that has adjustable frequencies so you can further fine-tune its output.
Following these simple steps ensures that your plants receive consistent light without experiencing any adverse effects from unwanted flicker.
When to Replace Grow lights
It’s important to know when to replace your lighting setup, as it can have a big impact on the health of your plants; after all, they could be exposed to up to 50,000 hours of light over their lifetime!
The lifespan of grow lights is usually between 25-50 thousand hours, depending on the type and quality. If you’re using LEDs, they tend to last longer than other types.
When replacing a grow light fixture, remember that lower-wattage LED bulbs will typically consume less energy than higher-wattage incandescent or fluorescent bulbs and are more efficient at converting electricity into visible light.
Replacing a grow light is no small task, but it’s necessary in order to ensure that your plants receive the best possible light source for photosynthesis and growth.
You should check the condition of your lights regularly for signs of flickering or dimming; these are indications that it’s time for a new one.
Also, pay attention to how long it takes for your plants to reach maturity, as this can tell you if they’re not getting enough light from their current setup.
It pays off in the end when you invest in reliable lighting equipment, so make sure you replace yours before any major problems arise!
