Can you put a t5 bulb in a t12 fixture?

With retrofit technology you can install T5 lights in older light models and enjoy the benefits of T5 lights even with T8 or T12 grow light fixtures. The biggest difference between T5 and T8 or T12 bulbs is the bulb diameter size and the bulb base that fits together with the correct fixture.

T8 lamps are fluorescent lights one inch (or 8/8ths) in diameter. T5 lamps are 5/8th in diameter. The smaller the lamps the more energy efficient they are. For some applications, one T5 bulb can replace two T12 bulbs, providing even greater energy savings (a process called “de-lamping.”)

Subsequently, question is, will a t5 fit in a t8 fixture? Because of this, you may think that T5 lamps will not work on T8 lamps. T5 lamps are shorter or smaller than T8 lamps in terms of the diameter. So it’s not an ideal replacement. However, there are some luminaires that can accept both with the help of changing sockets and ballasts.

Also to know is, can I put a t8 in a t12 fixture?

T8 tubes are simply 1 inch in diameter versus the 1.5 inch diameter of T12 tubes. In an effort to make LED tube lights compatible with the internal dimensions of most fixtures, you will find that most LED tube lights feature a T8 or 1 inch diameter. They can indeed be used in T12 fixtures.

Are t5 bulbs being discontinued?

Lamps affected include fluorescent 4 foot T8, T5, T5HO and 2 foot U-bent lamps. However, many 32W lamps have either been re-engineered or discontinued by the manufactures. Most current fluorescent T5 linear lamps already comply with the new standards. The 2015 rule-making takes effect in January of 2018.

Do they still make t12 bulbs?

Also effective July 14, 2012 the US Government will make lamp manufacturers to discontinue T12 lamps so if you just have to have T12 lamps you better buy a couple of cases. On July 14, 2012, recently enacted DOE regulations will take effect that will also eliminate the T12 lamps that the ballasts operate.

Can you replace t12 fluorescent tubes with LED?

Install a direct wire or ballast-bypass linear LED lamp. Right now, a ballast-bypass is our top LED replacement option for T12 fluorescent tubes. Ballast-bypass LEDs work straight off the line voltage flowing directly to the sockets, requiring you to remove the original fluorescent ballast.

Which is brighter t12 or t8?

The standard T8 produces 2,800 initial lumens per lamp, 6% brighter. But the standard T12 lamp produces 2,300 design lumens and the T8 produces 2,660 design lumens.

What does t5 mean for light bulbs?

Fluorescent lamps, or fluorescent linear tubes as they are also known, are categorized according to their wattage, shape and diameter. The “T” in T5 indicates the bulb is tubular shaped, while the “5” denotes that it is five eighths of an inch in diameter.

Are t5 and t10 bulbs interchangeable?

The main difference is in size…the T8 is one inch in diameter and everything else is divisible by that number: T5 = 5/8 inch, T6 = 6/8 inch, T8 = 1 inch, T10 = 1.25 inches (10/8), T12 = 1.5 inches in diameter (12/8). While the size is the main difference there are other differences that are worth mentioning.

Do t5 lights need a ballast?

You can mix and match lamps in the same fixture, so long as they are all correctly rated (HO or VHO.) You don’t need a ballast. T5 Fluorescent grow light fixtures come with a built in electronic ballast.

Which is better t8 or t5?

T5 HO lamps have a much higher lumen output than T8 lamps with the same tube length. In most cases a 2-lamp T5 HO fixture produces more light than a three-lamp T8 fixture. T5 lamps have a higher optimal performance temperature than T8 lamps (95°F vs 77°F).

Can I use a t5 bulb in a t4 fixture?

panmanmatt New Member. Sorry to say, but they are not interchangeable. They require different ballasts to fire the bulbs. A T4 12w ballast will not fire a 20w HO T5 bulb.

How do I convert a t12 light fixture to LED?

If you’re converting your existing T12 lamps to LED, you have five options to choose from: Install ballast-bypass linear LED lamps. Install electronic ballast-compatible linear LEDs and a new electronic ballast. Install a new LED tube with a remote driver in the fixture. Install an LED retrofit kit.

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.

Do I need to change the ballast for LED lights?

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.

Will LED bulbs work in fluorescent fixtures?

Many LED tubes are “plug and play”, meaning you can just install them like you would a fluorescent bulb. For this to be true, look for bulbs that are “ballast-compatible” meaning that they can use the ballast already installed in your fluorescent fixture to power the LEDs.

How do you bypass LED light 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.
