Can you use two ballasts one light?

actually, there's a couple things you can do. you can get a flip flop, and run two lights from one ballast. also, i can't remember where i saw it, but there's a new ballast out that is 2 ballasts in one, so you can run 2 lights from this one/dual ballast. now, you may also be able to get a multi ballast flip

Furthermore, can you run 2 lights off ballast?

Also, how do I wire a 2 way ballast? How to Replace 2 Lamp Series Ballast with Parallel

Connect each of the individual blue wires from the parallel ballast to each pair of the lampholder individual wires (red and blue).
Connect the common red wire from the parallel ballast to the yellow pair of lampholder common wires.

Also know, how do you wire a single light ballast?

After 1 Lamp Rapid Start Ballast is Replaced with a 2 Lamp Rapid Start Ballast. The ballast blue wires connect to one end of the lamp, the red wires connect to the other side. The common yellow wires are capped with small wire connectors.

How do you change a two bulb ballast?

Replace the fluorescent light ballast in four steps.

Photo 1: Remove the bulbs and fluorescent light fixture cover. Unplug the fixture or turn off the power at the main panel.
Photo 2: Cut the old ballast wiring.
Photo 3: Unscrew the old ballast.
Photo 4: Install the new ballast.

Can you run hid without ballast?

If you do not use the ballast, there will be nothing to regulate the electrical power and the bulb may use more energy and burn out quickly. On the other hand, the bulbs may draw less energy and you will be stuck with uneven lighting on the road. Usually, HID bulbs cannot run on DC power.

Can I use a 4 lamp ballast for 2 lamps?

Many replacement ballasts can be wired for several combinations of lamps, such that a 4-lamp ballast can be wired to a 3 or 2 lamp fixture. This will be shown right on the label and wiring diagram. There is no shortcut, you must look at the specific ballast and see whether the ballast is listed for that use.

What are the yellow wires on a ballast?

you would normally have the yellow connected to one end of a bulb and the other end will be connected to either a blue or a red wire . it is basically one half of the source power circuit, yellow on one end, and either blue or red to the other end . The two wires provide the source power to light a bulb.

Can I use a 4 lamp ballast for 3 lamps?

A 3 lamp parallel ballast can be replaced with a 4 lamp parallel ballast. The two yellow wires on a 4 lamp ballast are connected together inside the ballast.

How do I convert a t12 to t8 ballast?

How to Change a T12 Ballast to a T8 Ballast

Purchase a T8 ballast at a home improvement retailer.
Cut off the ends of the yellow wires from the fixture.
Repeat Step 2 by joining one of the blue wires from your T8 to the two blue wires coming out from the fixture.

Can you change a ballast with the power on?

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. Fluorescent bulbs need ballasts to regulate the power.

What happens if you wire a ballast wrong?

If you use a wrong sized ballast the LRC will not be tuned so you are likely to not start the lamp at all. There is the possibility of burning out components pre-maturely also due to overcurrent and overvoltage conditions particularly if using a larger ballast on a smaller fixture.

Do I need to remove the ballast to use an LED bulb?

LED technology does not require a ballast to regulate the amount of energy flowing to the lights. Additionally, removing the ballast will reduce energy usage and result in even great cost-savings as ballasts continue to draw more power than necessary.

How do you bypass a ballast?

Cut the socket lead wires.

The socket lead wires (most likely red and blue-colored wires) are located on the other side of the ballast and connect to wires going out of the ballast to the sockets (which should be non-shunted sockets for T8 LEDs). These output wires provide the power to the lamps.

Will a 277v ballast work on 240v?

In this case, the answer is yes. Just like fluorescent ballasts marked 120v-277v, an LED driver marked 120v-277v will self-adjust to the voltage of the power supply being supplied, assuming the voltage falls in the described range. For example, 120v-277v will operate on any voltage between 120v and 240v.

How does a ballast work?

Simply put, the ballast is the heart of a fluorescent light fixture sending energy (pumping blood) through the lamp. A ballast provides the correct amount of voltage to start the lamps and regulates the amount of current that flows to them once they're on.

How much does a ballast cost?

A replacement ballast costs about $10-25 depending on capacity and brand. The bite is that an electrician trip charge (which includes 30 or 60 minutes work) is going to be $75-150 probably - for about 5 minutes work on each light fixture.

Do you have to be a licensed electrician to change a ballast?

Depending on the size of the replacement project, a licensed electrician isn't always necessary; however, if you don't have the proper tools or experience, it is a good idea to consult with a licensed electrician before attempting the replacement.

How do I know if a ballast is bad?

If your fluorescent lighting is displaying any of the signs below, it could be a symptom of a bad ballast:

Flickering.
Buzzing.
Delayed start.
Low output.
Inconsistent lighting levels.
Switch to an electronic ballast, keep lamp.
Switch to an electronic ballast, switch to a T8 fluorescent.

How do I know if my ballast is t8 or t12?

This will reveal a lot about your current fluorescent tube and usually indicate if the bulb is T8 or T12. If no markings are available, the size in diameter of the tube is the easiest way to determine the type you have installed. T8 tubes are 1-inch in diameter and T12 tubes are 1 1/2 -inch.

What is the difference between t8 and t12 bulbs?

The number that comes with the T is used to denote the diameter of the fluorescent tube. Since the measurements come in eights of an inch, the T8 has an inch of diameter while a T12 comes in 1.5 inches. The narrower your choice of a fluorescent lamp is, the more efficient its energy output will be.

How many types of ballasts are there?

There are two lamp families that work with a ballast: fluorescent and HID. And there are two types of ballasts in each family: magnetic and electronic. Magnetic ballasts are the older ballast technology. For the fluorescent family, both T12 linear fluorescents and two-pin CFLs use magnetic ballasts.
