Can you splice ballast wires?

In the case of installing an electrical fixture, a splice is used to connect the lead wires of your fixture (it doesn’t matter whether it’s a ceiling fan, ballast, or downlight housing, they all have cable leads) to your house’s line voltage.

The common yellow wires connect from the ballast to push-in connectors on one of the right holders of lamp 1 or 2. Two yellow wires connect the common lampholders together.

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.

What do the letters on a ballast mean?

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. A fixture with a T8 ballast must use a T8 bulb, etc.

What is a ballast bypass?

A ballast bypass is when you remove a ballast from the electrical circuit that goes to your light fixture.

Is direct wire the same as ballast bypass?

Ballast-bypass, line voltage, or direct wire linear LED (UL type B) Bypass the ballast linear LEDs – also known as line voltage or direct-wire linear LEDs – work straight off the line voltage flowing directly to the sockets, requiring you to remove the original fluorescent ballast. Jump ahead to pros and cons.

Is it safe to bypass a ballast?

Safety risk

The most significant negative to a ballast-bypass linear LED is the risk of electric shock since the sockets carry line voltage. It’s a common practice to place a finger on the lamp pins while you are trying to install it, and this becomes a risky endeavor when using single-ended ballast-bypass lamps .

Can you put a metal halide bulb in a regular light fixture?

This is why a metal halide bulb will not work in a standard household lighting fixture — aside from the fact that the larger E39 base will not fit. Similarly, a standard incandescent bulb would never be able to withstand the ballast voltage in a metal halide fixture.

Do metal halide lights need ballast?

A metal halide lamp’s starting requirements are important because they impact the type of ballast that the lamp requires. Two methods are used to start MH lamps: probe start (standard start) and pulse start.
