Lighting Insights Blog. Actually, yes. But before you make a decision, there are other LED solutions to consider for a high-efficiency lighting option for existing T12s. A lot has changed in just a few years in the lighting industry. That product was discontinued.
Additionally, beginning in , legislation to cease the production of magnetic ballasts — the functional heart behind T12 lamps — went into effect. While there are still some of these 1. Energy regulations and the recently boosted affordability of more energy efficient lamps are snuffing T12s out.
If you're converting your existing T12 lamps to LED, you have six options to choose from:. Right now, a ballast-bypass is our top LED replacement option for T12 fluorescent tubes. But read carefully, because there are safety concerns. We only recommend a ballast-bypass using double-ended LED tubes. Single-ended tubes can present various safety hazards. With any ballast-bypass or direct wire solution, we suggest using a qualified electrician.
Another benefit to using a double-ended tube is most are compatible with shunted and non-shunted sockets. Ballast-bypass LEDs work straight off the line voltage flowing directly to the sockets, requiring you to remove the original fluorescent ballast. This solution might cost more in labor and sockets, but it will pay off in energy savings. Buy ballast-bypass T8 LED tubes here. Want to know the pros and cons of a ballast-bypass?
Check out our complete article, "Plug-and-play vs. 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.
Pretty nice. This is another top recommendation if you want to gain substantial energy savings, avoid mercury, and gain long life lighting. Current electronic ballast-compatible LED tubes give you great flexibility and savings, provide a solution that you shouldn't have to touch for years, and keep the up-front cost lower than a new fixture. Buy electronic ballast-compatible LED tubes here.
Remote-driver LEDs are the most energy-efficient option in this list as there is no ballast draw involved in powering the lamp. This setup has a great reputation for performance and reliability, but the cost is generally a hair higher than an electronic ballast and plug-and-play lamp combo.
The best uses for a remote driver LED are places where you're looking for high-performance lighting, or where you need to maximize every bit of energy savings. Read more about ballast draw in our article, "What is a ballast factor and how does it affect my fluorescent tubes? If you want to freshen up the look of your fixtures but you don't want to open the ceiling or completely remove old fixtures, this could be a great option. And CRI color rendering index , nobody will sell you less than 80 anymore, but you can get as high as Your old tubes were probably CRI, the difference will blow you away.
The 4-foot bi-pin type bulb is far-and-away the most common. They come in two primary types that you'll spot in an instant:. It's rare, but on occasion you will run into an oddball base type. Most of these critters are T Just for the record, here are the three base types that are possible:. You can now get "tubes" which are in fact a row of LED lights. They come in a variety of color temperatures and CRIs not as good as you can buy in real fluorescent.
Don't just throw a pair in the cart, they take some wiring. F40 is lumens F32T8 is lumens. That's 90 lpw for T12 and Most comparisons between T12 and T8 were done with low end T12 compared to high end T8. Notice that they never compared high end T12 to low end T8. Wal mart sells an lumen F32T8 and a lumen T These have been gimped down to make led appear better than they really are.
Since magnetic ballast are now banned why do they still rate T12 and T8 on them. If they rated the advantage series T12 and T8 on electronic ballast the T12 would make lumens at 36 watts and the T8 would make lumens at That's lpw and T5 is already rated on electronic ballast, that's why they appear better than T12 or T8.
