Are T12 bulbs discontinued?

Are T12 bulbs discontinued?

As a result, in 2009, the department announced the eventual phase out of the 1.5-inch-diameter fluorescent T12 tubes. The mandate said production of the tubes would have to cease after July 14, 2012.

Are F40 and T12 the same?

A T12 is 12/8ths of an inch, or 1.5″ in diameter. A T5 is 5/8″ in diameter. All F32 and F40 lamps are essentially 4 foot long lamps (47″ if you don’t count the pins). The FR71T12 is actually a 71″ long x 1.5″ diameter lamp that can handle from 80-120w and is typically run at 100w.

What does T12 mean on a light bulb?

The associated number represents the diameter of the lamp. This number is the numerator in a fraction where the denominator is 8 and the length is in inches. For example, with a T12, the diameter is 12/8, or twelve eights of an inch. Another way to say this is that the diameter is equal to 1.5 inches.

What is the difference between a T8 and T12 lamp?

The main difference between T8 and T12 tubes is the tube’s diameter. T12 tubes are 1.5″ in diameter while T8s are just one inch. All other things—socket sizes, lengths, distance between pins—are the same. T8 LED tubes won’t fall out if you try to install them in a T12 fixture—they’ll fit just fine.

Why are T12 lamps being discontinued?

In response, Congress made legislation stating that T12 linear fluorescents and other inefficient lighting technologies would no longer be manufactured. This legislation was put into action in 2012 with the DOE regulating T12 linear fluorescent lamps as a way of encouraging consumers to be more energy efficient.

Can I put a T8 bulb in a T12 fixture?

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.

Can I replace a 34W fluorescent bulb with a 40W?

There could be a margin of error for various reasons. Usually it’s fine to swap a 40W tube with a 34W tube, but some ballasts can overheat with a 34W tube installed. Check the ballast to see if it says it’s rated for 34W tubes, and if it doesn’t then check with the manufacturer of the ballast.

What does the T stand for in fluorescent tubes?

The “T” designation in fluorescent lamp nomenclature stands for tubular — the shape of the lamp. The number immediately follow- ing the T gives the diameter of the lamp in eighths of an inch.

Are T8 and T12 sockets the same?

Can I replace a T12 with a T8?

T8 LED lamps which are not direct-wire compatible (with ballast) will require a T8 ballast to operate, so unless the T12 ballast in the T12 fixture is replaced with a T8 ballast, a non-direct-wire compatible T8 LED lamp will not work in a T12 fixture.

Can you replace a T12 lamp with a T8 lamp?

Will T8 lamps work with T12 ballast?

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.

Can you put lower watt fluorescent bulbs in higher watt ballast?

Using a higher wattage ballast on the lower wattage bulb is overdriving by definition It has to do with how the ballasts work. They do not produce output according to what bulb is attached. Ballast output is the same, no matter the bulb.

Can you use a higher watt fluorescent bulb?

Yes, you can use a compact fluorescent (CFL) bulb that produces more light as long as it doesn’t exceed the wattage recommended for the fixture. Light bulbs are commonly compared using both watts and lumens. Watts are the amount of electricity used by the bulb while lumens measure the light produced.

What happens if I put a T12 bulb in a T8 fixture?

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.

Are T12 and T8 sockets the same?

Do T8 and T12 bulbs use the same socket?

T12 vs T8 Fluorescent Tubes

T12 tubes are 1.5″ in diameter while T8s are just one inch. All other things—socket sizes, lengths, distance between pins—are the same. T8 LED tubes won’t fall out if you try to install them in a T12 fixture—they’ll fit just fine.

What happens if you put a T12 bulb in a T8 fixture?

What happens if you put a 60w bulb in a 40w socket?

Using a light bulb with too high of wattage can lead to overheating of the light bulb. This heat can melt the light socket as well as the insulation of the wires. Once that happens, you put yourself at risk of arc faults, and this is something that could even lead to property fires.

Can I put a 100W bulb in a 60w socket?

The answer is YES. You can use an LED bulb having a higher wattage equivalent than your fixture allows — provided the LED bulb consumes less wattage than the fixture.

What happens if you put a 60w bulb in a 40W socket?

Can you put a T8 lamp in a T12 fixture?

What happens if I put a t12 bulb in a T8 fixture?

Will T8 lamps work with t12 ballast?

Senior Member. If you run a t8 bulb on a t12 ballast you will have premature bulb life as the t12 ballast will over “tax” the bulb. If you run it vice versa and have a t8 ballast running a t12 bulb you will have premature ballast life as the t12 bulb takes more to run and will over work the ballast.

Can you replace a T12 with a T8 LED?

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.
