T12 Light Fixtures Installation and Upgrade Guide

Installing T12 light fixtures can be a straightforward process, but it's essential to follow the correct steps to ensure a safe and efficient installation.

T12 light fixtures are typically installed in commercial settings, such as offices and warehouses, due to their high lumen output and long lifespan.

To begin, you'll need to turn off the power to the circuit at the main electrical panel, and verify that the circuit is de-energized using a non-contact voltage tester.

Before starting the installation, make sure you have a replacement T12 light fixture that matches the existing one in terms of wattage, voltage, and color temperature.

If your goals are to maximize your lighting system investment, then your options for T12 replacement are limited. You can choose to upgrade to a more energy-efficient lighting solution.

You have six options to choose from when converting your existing T12 lamps to LED. This range of options allows you to pick the best fit for your specific needs.

The payback on your lighting investment is a crucial consideration. Whether you're making spot replacements or working on a complete T12 to LED retrofit, the payback is a key factor in the conversation.

T12 light fixtures have been around for a while, but they're not as efficient as they used to be. Energy savings of 55% to 85% can be achieved by replacing them with LED retrofit lamps.

Replacing T12 fixtures with LED retrofit lamps can also reduce maintenance costs due to their significantly longer lifetime. You can expect to get 30,000 to 80,000 bulb hours out of an LED, compared to 2,000 to 25,000 bulb hours for traditional bulbs.

One of the biggest advantages of LED retrofit lamps is that they don't generate as much heat as traditional bulbs. Standard filament bulbs generate 90% heat, 10% light, while LEDs do the opposite.

Here are some of the benefits of LED lighting in a nutshell:

T12 fluorescent tubes are 1.5 inches in diameter, while T8 tubes are just one inch in diameter. T8 tubes are also a good fit for T12 fixtures, so you can easily upgrade without worrying about compatibility.

T12 fixtures have non-shunted tombstones, making it easier to convert to LED tubes. This means you can skip the extra work of replacing shunted tombstones found in T8 fixtures.

You can cut your lighting bills in half and increase the lifespan of your lights by nearly 70% by switching to 4ft or 8ft LED tube lights. LED tubes also work well with occupancy sensors or other control systems.

T12 tubes haven't been manufactured in large quantities in the US for a few years, making them harder to find. Legislation has also made it difficult to produce magnetic ballasts, which are essential for T12 lamps.

If you need to replace a T12 fluorescent tube, it's probably due to a burnt-out lamp or ballast. You have options like linear LEDs, which offer more energy efficiency and a smaller utility bill.

Installing T12 LED tubes is a quick process that can be completed in minutes. You'll need to prepare your fixture, which may involve replacing existing tombstones if you have a T8 fixture, but not if you're using a T12 fixture.

The Philips UniversalFit tubes are a great option for a hassle-free T12 to LED upgrade. They plug right in and work off the existing ballast, making them a simple and efficient choice.

If you want to upgrade your T12 fixtures without replacing them entirely, consider installing an LED retrofit kit. This option allows you to freshen up the look of your fixtures without opening the ceiling or removing the old ones.

Installing tubes is a relatively quick process. You can convert a fixture in minutes after the first one.

You won't need to replace the tombstones if you're using a T12 fixture. This is a plus, as it saves you some extra work.

The Philips UniversalFit tubes are a great option for the easiest and quickest T12 to LED upgrade. They plug right in and work off the existing ballast.

The wattage is slightly higher with this approach, but the simplicity is hard to beat.

Installing a retrofit kit is a great option if you want to update your existing T12 fixtures without completely replacing them. This approach can be a bit more involved than some of the other options, but it can also be very cost-effective.

You can install an LED retrofit kit in your existing T12 fixtures, which can cut your lighting bills in half and increase the lifespan of your lights by nearly 70%. This is especially true if you're using occupancy sensors or other control systems to manage your lighting.

One of the benefits of retrofit kits is that they're relatively easy to install, and can be completed in a matter of minutes. They're also a great option if you want to freshen up the look of your fixtures without having to open the ceiling or completely remove the old ones.

Some retrofit kits, like the Philips UniversalFit tubes, are designed to plug right in and work off the existing ballast. This makes them a very simple and straightforward option, although the wattage may be slightly higher than a typical ballast-bypass option.

You have six options to choose from when it comes to LED retrofit kits, so it's worth doing some research to find the one that's best for your specific needs.

You can retrofit T12 to LED without changing out the ballast, but it's essential to consider other LED solutions for a high-efficiency lighting option. This approach can save you money and reduce waste.

Installing LED tubes is a fast and simple process, taking only minutes to complete after the initial setup. You won't need to replace the tombstones if you're using a T12 fixture.

The ideal upgrade for T12 and T8 fixtures is to switch to 4ft or 8ft LED tube lights, which can cut your lighting bills in half and increase the lifespan of your lights by nearly 70%.

Upgrading to LED tube lights is a great way to breathe new life into your old T8 fixtures. This simple swap can cut your lighting bills in half and increase the lifespan of your lights by nearly 70%.

By switching to LED tube lights, you'll also improve the operational life of your tubes. Using occupancy sensors or other control systems can make a big difference, making them perfect for offices looking to save on their energy bills.

One of the biggest advantages of LED tube lights is their long lifespan. They can last anywhere from 30,000 to 80,000 bulb hours compared to 2,000 to 25,000 bulb hours for traditional lights. This means you'll spend less time and money on maintenance and replacements.

Here are some key benefits of upgrading to LED tube lights:

You can retrofit T12 to LED without changing out the ballast, yes, it's possible. This is one of the most common questions we come across.

The short answer is yes, but before you jump in and make the decision to upgrade without changing out the ballast, there are other LED solutions to consider for a high-efficiency lighting option for existing T12s.

One of the easiest and quickest T12 to LED upgrades is to install plug-and-play magnetic and electronic ballast-compatible linear LEDs. These plug right in and work off the existing ballast.

When the ballast gives out, swap it for a newer electronic ballast, and the tubes will continue to light your space. The wattage is slightly higher here than a typical ballast-bypass option, but you can't beat the simplicity of this approach.

Here are some key benefits of this approach:

This option is a great choice for those who want to upgrade their T12 fixtures to LED without having to replace the ballast.

The payback on replacing T12 light fixtures is a crucial consideration for any project. You can use tools to help navigate the calculations and determine the return on investment.

Whether you're making spot replacements or a complete retrofit, the payback is likely a big part of the conversation. The savings from replacing T12s with LED options can be substantial.

T12 light fixtures were discontinued in 2012 due to legislation from Congress, which aimed to encourage consumers to use more energy-efficient lighting technologies.

The Department of Energy (DOE) was tasked with regulating the lighting standards in 1992, after Congress ordered them to keep an eye on the growing technology.

T12 linear fluorescent lamps were one of the inefficient lighting technologies that were no longer manufactured, making it harder for construction workers and electricians to find replacement bulbs.

In 2012, the DOE regulated T12 linear fluorescent lamps as a way to encourage consumers to switch to more energy-efficient options.

Congress made this change in response to the creation of LEDs, which marked a significant shift in lighting technology.
