Will a t8 ballast work with t12 bulbs?

As far as safety is concerned, you can exchange them. If you place T12 tubes in a fixture with a T8 ballast, you will wear out the ballast and have to replace it. If you place T8 tubes in a fixture with a T12 ballast, then the tubes will have a shorter life due to a higher current through the tube.

Fluorescent lights are tube shaped lamps with a chemical phosphor coating on the inside of the tube. The have small pins on each end that fit into the ballasts located in light fixtures. T12 lamps have a diameter of 1 ½ inches (or 12/8th of an inch.) T8 lamps are fluorescent lights one inch (or 8/8ths) in diameter.

Subsequently, question is, how do I know if my fixture is t8 or t12? Replace Current Lamp Read the lettering on the burned-out lamp. You will see either T8 or T12 stamped on one side near the end with the prongs. You also will see the lamp’s rated wattage, usually 32 watts for T8 and 40 watts for T12. Measure the diameter of the lamp.

Herein, can you use a t8 bulb with a t12 ballast?

T12 tubes pull 40 watts, and are frequently being replaced with lower wattage t8 tubes, which operate on 32 watts. When posing the question can a t8 light work on a t12 ballast, the short answer is no. The only way around the dilemma is to replace the ballast.

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.

Can you replace a magnetic ballast with an electronic ballast?

Newer electronic ballasts are far more energy-efficient, don’t require a starter and are not as affected by cold temperatures as the magnetic predecessors. If you have an older fixture, you can switch from a magnetic ballast to an electronic ballast in a few minutes with some basic hand tools.

Are t12 bulbs going away?

In effect since July 2012, the legislation eliminates nearly all 4-foot T12 lamps, some 4-foot T8 lamps, most 8-foot T12 lamps, and almost all standard halogen PAR38, PAR30 and PAR20 lamps from the market. T12 technology is over 80 years old. longer lamp life. better color rendering.

Can I put LED bulbs in my 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.

Can I put a t8 ballast in a t12 fixture?

you have to remove the ballast- as most t8 tubes have an electronic one inside. If you put them in t12- you will burn the bulb up and they will work sporadically before they die. Also the fixture gets blackend.

What happens if you use wrong ballast?

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.

Which is better t8 or t12 bulbs?

T8 LEDs produce twice as many lumens per watt as a T12 lamp and ballast. It also generates 27% more light per tube than T12 and reduce energy use by about 40%. And it gets better! T8 LEDs emit the light in a 120° degree beam; T8 and T12 fluorescents throw light 360°, which often means wasted light.

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.
