How do I know if a ballast is compatible?

Simply turn the light on, then take a photo of the fixture using your smartphone or digital camera. If there are no dark bands on the resulting image, you have an electronic ballast that is likely to work with direct drop-in LED tubes (with caveats: see the next section below).

What are the 4 ballast types?

Types of fluorescent ballasts

Rapid start ballasts work kind of like preheating an oven.
Programmed start ballasts are typically paired with occupancy or motion sensors. ...
Probe start ballasts are the older type and not very easy on the HID lamp. ...
Pulse start ballasts don't use a starting probe electrode.

How do I know if my ballast is t8 or T12?

Like a generation 3 if you compare them side-by-side the t5 is smaller. Here's a t8 and the t12 is

Can I replace a T12 ballast with a T8 ballast?

The easiest and lowest price option to replace a T12 is a T8 linear fluorescent. They have become the go-to option for pre-existing T12s. If you still have magnetic ballasts, switching to a T8 will require a ballast swap.

What is the lifespan of a ballast?

The average life expectancy of a fluorescent light ballast is 10-15 years.

How do you read a ballast number?

The most common types are T12, T8, and T5. The T stands for tubular and the number indicates the diameter in 1/8 of an inch. Lamp diameter is determined by ballast type. A fixture with a T12 ballast must use a T12 bulb.

Are ballasts interchangeable?

Matching ANSI codes guarantees that the ballast you chose can be used with your lamp. However, ballasts are often compatible with more than one lamp, and vice versa.

How do you test if a ballast has gone bad?

With your multimeter set to ohm, or “Xl1” if there are multiple ohms on your meter, insert one of the probes into the wire connector containing the white wires. Touch the other end to the remaining blue, red, and/or yellow wires attached to the ballast. Your multimeter won't move if your ballast has gone bad.

What can I do with an old ballast?

According to EPA Toxic Substances Control Act (TSCA) regulations, the material must be incinerated. The entire lighting fixture does not need special handling and disposal as long as the ballast (electrical box) is not leaking. The non-leaking ballasts can be removed and recycled or disposed of properly.

What is the most common ballast?

A further upgrade is the high-frequency ballast, which is an electronic ballast that supplies power frequencies at about 20,000 Hz. This is the most common type of ballast because it consumes up to 30% less power with the same light output compared to a magnetic ballast.

What is the difference between N and SC ballast?

A: The n designation is new and the sc is the old designation. there appears to be no difference in the two.

What happens if you put a T8 bulb in a T12 ballast?

All other things—socket sizes, lengths, distance between pins—are the same. T8 LED tubes won't fall out if you try to install them in a T12 fixture—they'll fit just fine.

How do I know what kind of ballast I have?

Stand under the light or a place close to the light and point your cell phone camera at the light. If you can see some strong dark strips flickering in your camera, it must be a magnetic ballast based light. Otherwise it should be an electronic ballast based light.

Can you replace a T12 with a T8 LED?

Now the LED Tubes T8 are available for all those base and 8ft, and also 2ft, 3ft, 4ft, 5ft, 8ft too. So it's quite convenient to use a T8 LED Tube to replace the old T10 and T12 tubes. While the size is the main difference there are other differences that are worth mentioning.

Are T12 bulbs being phased out?

The Ecodesign Regulation set a schedule to eliminate integrally-ballasted compact fluorescent (CFLi) and T12 linear fluorescent (LFL) lamps in September 2021, and most T8 LFLs in September 2023.

What happens if you don't bypass the ballast?

You could destroy the LEDs. The ballast from fluorescent lights uses a much higher starting voltage (around 600 V) to get them started. It lasts for fractions of a second before dropping down to the normal line voltage. Depending on the LED circuit tolerances, it could be destroyed.

Can I change a ballast with the light switch off?

When the ballast fails, the bulb will flicker or fail to light. Although changing a ballast is safer with the power off, sometimes it is impractical, such as in a crowded store or office space, and you must replace the ballast without cutting the power. This can be done safely with some preparation and the right tools.

What causes a ballast to burn out?

Ballast failure is often caused by the surrounding environment—mainly heat and moisture. When it's too hot or too cold, a ballast can burn or fail to start your lamps. Heat, along with continuous condensation inside an electronic ballast, can cause corrosion over time.

When should you replace ballast?

The ballast takes in electricity and then regulates current to the bulbs. A typical ballast will generally last about 20 years, but cold environments and bad bulbs can decrease this lifespan significantly. You can get a new ballast at a hardware store or home center and install it in about 10 minutes.
