What is the difference between an LED driver and a ballast?

Once the light is on, the ballast then acts as a current regulator. LED drivers convert high voltage, ac current into the low voltage, direct current that LEDs are designed to run on. Both fluorescent ballasts and LED drivers protect the light from fluctuations in the electrical supply.

Do I need to remove ballast for LED lights?

An LED light does not require a ballast because it uses a component called a “driver” to regulate the power going into the bulb.

Will LED work with ballast?

In the interest of making things simpler, manufacturers developed LEDs that could work directly off the ballasts that were already being used with no external drivers needed (There is a driver inside the LED that works with the ballast; this must be an electronic ballast, and one still has to make sure LED and ballast …

What is a ballast or driver?

Ballasts and drivers are devices, other than the lamps themselves, that convert raw power into a form suitable for a light source. ​ Devices include electronic and electromagnetic ballasts in interior and exterior fluorescent, high-intensity discharge (HID), and low-pressure sodium (LPS) lighting systems.

Will ballast compatible LED tubes work without a ballast?

The T8 LED tube won’t work without the ballast, so you are forced to continue buying and replacing ballasts as long as you have an LED tube that is ONLY ballast dependent.

Can I replace my fluorescent tubes with LED?

Yes, you can replace fluorescent tubes with LED tubes or LED-integrated fixtures. If you just want to replace the bulbs, you can use plug-and-play, direct-wire, or hybrid LED tubes. Plug-and-play tubes are the easiest to install as they do not require any rewiring to the fixture.

Do LED replacement bulbs need a ballast?

No LED bulbs require a ballast, although some are engineered to work with an existing ballast. You will find ballast-compatible or “plug-and-play” LEDs that are designed to replace linear fluorescents, compact fluorescents, or HIDs. Incandescent and halogen lamps do not require a ballast.

How do I know if my ballast is compatible with LED?

However, direct drop-in LED tubes are compatible only with fixtures that have electronic ballasts. You can determine whether you have a compatible fixture in seconds. Simply turn the light on, then take a photo of the fixture using your smartphone or digital camera.

What is in an LED driver?

The LED driver is a self-contained power supply which has outputs that are matched to the electrical characteristics of the LED(s). This helps avoid thermal runaway as the constant current LED driver compensates for the changes in the forward voltage while delivering a constant current to the LED.

Do all LED lights need a driver?

Because LEDs require a constant direct current of 12v or 24v, which is much lower than the voltage that the mains power supplies, all LED lights need an LED driver to convert the power supply into a more suitable one. This helps to prevent burnout and can lower the risk of fire.

Can a plug and play LED bulb be used without a ballast?

1. Plug-and-play or direct fit linear LED (UL type A) A plug-and-play, or direct fit, linear LED is probably what you’re imagining – a simple, one-for-one swap out of the original linear fluorescent lamp. This lamp works directly with the existing fluorescent ballast, so there is no rewiring or ballast change required.

How do you replace LED driver?

How do I choose an LED driver for my LED?

Use an LED driver with at least the same value as your LED(s). The driver must have a higher output power than your LEDs require for extra safety. If the output is equivalent to the LED power requirements, it is running at full power. Running at full power may cause the driver to have a shorter life span.

Why do LED drivers fail?

The LEDs usually fail, because they have been connected to a constant LED driver in parallel. If the LEDs have failed you may want to also replace the LED driver. We usually recommend using a model with an adjustable output, and trimming down the output voltage slightly, to avoid over powering the LEDs. 5.

How do you diagnose a bad LED driver?

Use a voltmeter and measure the output voltage of the LED driver. Constant current LED drivers may be at an exceedingly high voltage, so be careful. If the LEDs have failed the output voltage of the LED driver will be at its rated output (maximum voltage output for a constant current LED driver).

Are all LED drivers the same?

Unlike fluorescent ballasts, LED drivers are not standardized, so they are not interchangeable. They can vary in terms of output characteristics, electrical safety rating, input voltage, programmability, temperature rating, electromagnetic interference (EMI), dimming interface and form factor.

Can a LED driver be used as a power supply?

LED power sources that provide a “constant-current” output have typically been referred to as LED drivers. In the past, AC-DC power supplies that provided a regulated “constant-voltage” to LEDs were referred to as LED power supplies. Today, the terms “LED driver” and “LED power supply” are used interchangeably.

Can LED drivers be replaced?

LED Driver Replacement is a difficult process. When an LED fixture fails you need to either purchase a new fixture or replace the driver. In most scenarios it’s the LED driver that needs replacement (LED components have a longer shelf life).

Where do I put LED driver?

Firstly, the LED driver should be placed in a ventilated space and an access route should be made available for common maintenance purposes. Additionally, the IP, or International Protection Code or rating of the driver must be considered before finalizing the location for mounting the LED driver.

How long do LED drivers last?

The driver is the heart of the LED light, and driver life can range from 10,000 to over 50,000 hours, depending on the design features, heat sink efficiency, capacitor construction, and overall quality. The above graph compares the lifespans of various types of lighting.

What happens when an LED driver goes bad?

LED drivers rectify higher voltage alternating current to low voltage. If you have a good LED and a bad operating LED driver your high bay LED Lights won’t be functional for long. Most LED failures are not from the LED, but from the driver. Usually the circuits burn out and fail.

Can LED drivers be wired in series?

LEDs shall be wired in series as shown in wiring diagram. CAUTION: parallel wiring will damage LEDs. Dimming circuits are more sensitive to voltage drop and electrical interference from other electrical sources. Isolating LED wiring by dedicated circuit for each control zone is recommended.
