Often asked: Are all t8 bulbs the same?

Like T12 lamps, T8 lamps are available in a variety of color temperatures, including warm (3000 K), neutral (3500 K), cool (4100 K), and very cool (5000 K).

Are all T8 bulbs interchangeable?

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.

Are all T8 ballasts the same?

Not every T8 ballast is created equal. In such a case, a programmed start ballast might be better choice. Programmed start ballasts also work well in dimming applications, because as a lamp is dimmed, the electrodes cool. Programmed-start ballasts can heat the electrodes as they cool, prolonging lamp life.

How do I identify a T8 bulb?

T8 for example, means tubular (T) followed by the size/diameter (8). There may also be an abbreviated “HO” which indicates a high-output and “VHO” for very-high-output. In order to identify which size you need, the easiest way to tell is to read the label near the base of the tube.

Are T8 bulbs being discontinued?

US Department of Energy (DOE) regulations began phasing out various sizes of commercial fluorescent light bulbs in 2012. About all you can get today is the fluorescent workhorse of commercial lighting—the T81 bulb. By January 26, 2018 even T8s will be banned to align with new DOE energy efficiency standards.

Can I replace T8 with LED?

Yes, you can replace fluorescent tubes with LED tubes or LED integrated fixtures. As long as the bulb is compatible with the existing fluorescent ballast in the fixture, you simply remove the fluorescent and replace it with the LED tube light.

Are T5 and T8 bulbs interchangeable?

The major physical difference between T5 and T8 light bulbs is the length and diameter of the tube itself. The T5 tends to be slightly shorter than the T8 tube, and is significantly smaller in diameter. This factor is important to consider when looking at your fixture, because the two tubes are not interchangeable.

Are T8 and T12 fluorescent bulbs interchangeable?

T12 primarily run off a magnetic ballasts and T8 bulbs operate on electronic ballasts. So the bottom line is that these are not interchangeable and if you’re going to upgrade from a T12 to a T8 bulb, then you also have to change out the ballast.

What does T8 stand for?

What does “T8” mean? 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 T10 bulbs interchangeable?

The “T” associated with a fluorescent tube represents the diameter of the tube. T8, T10 and T12 tubes, despite being slightly different in size, all have the same end connectors, so they will all fit in the same fluorescent fixtures.

What are the different types of fluorescent light bulbs?

Types of Tube Light Bulbs While there are multiple types of LED and fluorescent tube lights, the three most common are T12, T8 and T5. The terminology comes from “T” for “tubular” and the diameter of the bulb in eighths of an inch, so “T8” represents a tube of 8/8ths of an inch, or 1 inch.

What does CW mean on a light bulb?

the cw stands for ‘ cool white ‘ and is the type/brightness of light it give outin comparison to ‘warm light’, ‘soft white’, and ‘daylight’.

Why are fluorescent lights being phased out?

Halogen bulbs are energy-hungry, expensive, and inefficient, the Government said on Wednesday. Phasing them out will cut carbon emissions by 1.26 million tonnes a year – equivalent to taking 500,000 cars off the road – and save households money on their energy bills.

Are fluorescent tube lights being phased out?

The UK began phasing out the sale of higher-energy halogen lightbulbs in 2018. In addition, the government also plans to start phasing out the sale of high-energy fluorescent lightbulbs, with a view to bringing an end to their sale from September 2023.

Can I use T12 in T8 fixture?

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.
