20 mar 2023 · If you're converting your existing T12 lamps to LED, you have six options to choose from: 1. Install ballast-bypass linear LED lamps. 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.
9 sty 2014 · Both T8 and T12 lamps use a G13 base; however, a T12 ballast will shorten the life a T8 lamp. Due to the US putting a ban on standard (40 watt) T12 lamps -- high efficiency ones are hard to come by but still exist -- some ballasts were made T8 & T12 compliant.
In answering this question, we need to evaluate for both physical as well as electrical compatibility. In terms of physical compatibility, both T8 and T12 lamps use the same G13 bi-pin base, so as long as they are the same length (e.g. 4-ft), a T8 lamp will physically fit inside a T12 fixture.
Convert existing fluorescent fixtures to LED technology with Feit Electric plug-and-play LED tubes. Installation is easy, no replacing/rewiring of the fixture is required to experience the same light output using less electricity than a standard fluorescent. Get instant on to full brightness even in sub-zero temperatures, with relatively cool running performance. Adjustable White bulbs allow ...
LED tube lights replicate the mechanical dimensions to ensure that they can be true retrofit replacements, and adopt the same form factor names (e.g. 4-foot T8 LED tube light). T8 and T12 fixtures are generally the same length and use the same pins, so mechanically they are usually cross-compatible.
T12 tubes are 1.5" in diameter while T8 tubes are just one inch. All other things—socket sizes, lengths, distance between pins—are the same. 8ft T8 LED tubes won't fall out if you try to install them in a T12 fixture—they'll fit just fine.
