What Is A T8 Light Bulb

What does T8 mean on a light bulb?

A T8 lamp (on the right in the figure below) is eight-eighths of an inch, or one inch (2.54 cm), in diameter. Both T12 and T8 lamps use the medium bi-pin base, which allows T8 lamps to fit into the same luminaires as T12 lamps of the same length.

Is T8 the same as LED?

A T8 fluorescent that uses 32 watts of energy typically produces 2500 lumens of light. It’s LED equivalent, while using only 17 watts, produces 2200 lumens. Additionally, T8 LED light bulbs have a lifetime rating of 50,000 hours, more than 3 times longer than 15,000 hour average lifespan of T8 fluorescent lights.

What is the difference between T8 and T 12 bulbs?

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.

How do I identify a T8 bulb?

If the label is missing or illegible, you can measure the diameter to determine the size. The letter “T” will stand for tubular shape and the number will tell you the bulb diameter in eighths of an inch. T8 will have one-inch diameter, the T5 will have a 5/8 diameter, and a T12 will have 12/8 inch or 1.5 inch diameter.

Can I replace a T12 bulb with a T8?

The easiest and lowest price option to replace a T12 is a T8 linear fluorescent. They have become the go-to option for pre-existing T12s. If you still have magnetic ballasts, switching to a T8 will require a ballast swap. Another option is to move forward with an LED retrofit.

What’s better T5 or T8?

The T5 has a better lumen-to-watt ratio than the T8, implying that its output is more efficient and brighter per watt of energy used.

Should I replace T8 with LED?

Energy Efficient – On average, new T8 LED tubes are around 30% more efficient than Fluorescent T8 tubes. Lifespan- The average life of a T8 Linear Fluorescent Lamp is 30,000 hours, while a T8 LED will last 50,000 hours. That said there are newer linear fluorescent T8 lamps that can last up to 84,000 hours.

Are T8 bulbs fluorescent or LED?

LED is a directional light source. the 360 degree pattern given off by T8 fluorescent bulbs. In this case, only 30% of the light given off by the T8 fluorescent is actually hitting the intended target. This means you are not using all available light because the fluorescent bulb is also lighting the fixture.

Are LED T8 bulbs brighter than fluorescent?

You will not experience any kind of flickering or dark spots left at any of the indoor places. The LED tube lights are noticeably brighter than fluorescent tubes and you don’t get exposed to any kind of harmful rays such as UV/IV rays as well that can damage your eyes and can result in skin allergies as well.

Are T8 fluorescent bulbs being discontinued?

Even some T8 lamps have been phased out. US Congress has enacted legislation to prohibit the manufacture of these and other inefficient lighting technologies, and is calling for manufacturers to meet minimum efficiency requirements and lumens per watt for new products.

Can I use T12 LED in T8 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.

What are standard fluorescent bulb sizes?

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.

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.

What is T8 LED light?

T8 LED tube lights are interior LEDs used to replace T8 Fluorescent lamps. Each LED tube option is defined by how the LED interacts with the existing fluorescent ballast. LED tube lights offer options that can use the existing fluorescent ballast or other options that can bypass the ballast completely.

What is the brightest T8 fluorescent bulb?

The brightest four foot T8-sized LED tube light is the Barrina LED Shop Light Fixture. This tube shines with 5000 lumens using 44 watts. It replaces a 72 watt fluorescent tube.

Are fluorescent 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.

Which is brighter T8 or T5?

because the T8 tube light is high brighter than t5 tube. T5 led tube light, which is less filled with electrons and inert gas. In contrast, If you want to creat a darker lighting environment.

Is F40 the same as T8?

This means a T8 lamp is 8/8ths of an inch in diameter, or 1 inch. 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. It uses the different use of the F number.

How do I know what size fluorescent bulb I need?

In order to identify which size you need, the easiest way to tell is to read the label near the base of the tube. If this information is no longer legible, you can measure the bulb’s diameter. Fluorescent tubes are measured in eighths of an inch.
