LED Driver Replacement

LED Driver Replacement

If your LED light fixture or array is flickering, the problem may be with the driver and not the actual diodes. Before the driver fails completely, however, it typically signals a problem by misregulating power and either overdriving or underdriving your LEDs.

When choosing a replacement driver, you will want to match the voltage capabilities of the original. After that, you will need to consider the wattage requirements.


LED drivers regulate power for lighting arrays and fixtures. LED lights require constant current to operate and work best with a self contained driver that is able to supply a maintained level of power to the light. The driver also controls the power to the LEDs to ensure proper wattage levels and lifespan.

The central function of an LED driver is to convert higher alternating current (AC) running at a lower Direct Current (DC) voltage – typically 12v or 24v. It is important to led driver replacement use a driver with the right output voltage and efficiency rating.

When replacing a constant current driver it is important to find one that matches the LED module rated current; this can be done by photographing the LED module and finding a replacement driver with the same wattage rating. This can save time and money from having to purchase an entire fixture for a simple driver replacement!


Often the power supply of an LED light fixture will fail and stop sending enough current to all the LEDs. This can lead to them burning out and decreasing the quality of your lighting display. Fortunately, you can identify a failing power supply by looking at how much voltage the LEDs are receiving, which is usually listed as a range or in milliamps (mA).

When selecting a replacement, make sure it matches this voltage. If you choose a higher voltage, it can cause your lights to burn out. Also, a lower voltage may be too weak to provide sufficient power to the LEDs and can cause them to flicker.


An LED driver is necessary for an LED lighting system to function properly. It converts incoming voltage into direct current for the LEDs. It also helps regulate the amount of forward current that jumps between the p-n junctions of each LED. Without a driver, your LEDs can burn out or not turn on at all.

Some LED drivers are programmable to match the characteristics of their LED modules and fixtures they are paired with. This allows for precise pairing and maximized wattage and light output.

The first thing to do when attempting LED driver replacement is to make sure the power to that fixture is off. Electrical shocks are deadly, so don’t take any chances. Once the power is off, carefully remove the fixture to get to the driver’s power supply. Then, make sure the right replacement is selected. There are several things to consider, including programmability, input voltage, and form factor.


LEDs require a specific amount of power to work and stay bright. Too little will result in your lights dimming and may not turn on at all, while too much can stress the driver components leading to failure.

Choosing the right power supply is the first step in preventing damage to your LED lights and drivers. To do so, diode you’ll want to ensure the input voltage of your driver matches the electrical requirements of your LED lights. Next, you’ll want to ensure your LED driver has a maximum wattage capability that matches or exceeds the total wattage of your LED lights.

Constant current drivers will usually list a single output current rating, often in amps or milliamps, followed by a DC voltage range. Matching this range with the voltage rating on your original driver will help you find a compatible replacement. Generally, finding an option within 100-200 milliamps of the original will suffice.


Getting wet can wreak havoc on circuits that aren’t designed to be exposed to moisture, so check that your new driver is waterproof. This is especially important if you’re using it in an outdoor setting where water or dust could enter the system.

It’s also worth making sure your replacement is rated for the same power input as your old driver. Input voltage will be listed on the LED driver’s label and it should match your power supply’s rating requirements. If your current power supply is constant voltage, use a replacement that provides the same amount of voltage; if it’s constant current, find a driver that matches the exact wattage you need for the LED lights.

Flickering is a sign of a problem with the driver, and the more noticeable this becomes the more likely it is that your driver is starting to go bad. Quality drivers have circuits that are insulated from heat, and they’ll also display visual cooling designs to ensure that the electronics don’t get too hot.


LED drivers are electronic power regulators that convert incoming alternating current (AC) to direct current (DC) for use by the lighting system. They’re typically located in the luminaire, but can be field-mounted in some commercial applications.

Drivers can fail at different points in their lifespan, but most give warning signs before they stop functioning entirely. One of the most common is flickering LED lights, which is caused by the driver failing to transmit proper voltage to your fixtures.

When looking for a replacement driver, start by matching up the input voltage. Constant voltage drivers will list a single voltage range, so it’s simple to find an exact match for your original. After that, you’ll need to check the wattage requirements. If the original driver was rated for a certain wattage, look for an equivalent or higher wattage to ensure the lighting system can work at maximum efficiency.
