The most commonly available is the T8 bulbs. This type of fluorescent tube lighting is the most popular because of its high CRi and many color temperature options. However, there are still many office spaces and homes that use the T12 fluorescent tube lights, especially in older buildings. Another reason why they are still used is the cheaper purchasing price compared to the others, but, they are no longer being made. T4 tubes are the smallest of the fluorescent bulb sizes, at only 4 eighths of an inch (0.5 in). Their size is what makes T4 lights popular for under cabinet lighting purposes and accent lighting for displays or a staircase. You should be aware that lumens are specific to the total amount of light emitted by the light source, while watts refer to the amount of energy consumed. As the levels of energy efficiency increase, the wattage decreases in relation to the generation of lumens.

Now you know all you need to about fluorescent tubes sizes and their differences. But below we will answer the questions that people ask us the most. What is the difference between T5 T8 and T12 lights? this variety of cool white is typically applied to office buildings. It is also considered suitable for formal home offices But first, you must know whether you are looking for office lighting with a lot of lumens or something with a softer light as this will make a difference to the option you require. T4 Fluorescent Lights T8 fluorescent tubing is the ideal option if you want to see a good level of detail. The high levels of colour rendering allow property areas and items to be shown to full effect. These tubes have a life expectancy of up to 15,000 and require a relatively low level of maintenance. Are T8 and T12 Fluorescent Bulbs Interchangeable? Compared to T5 lighting, the 8 Foot T8 tube lights are less economical. T8 lighting tends to be more expensive and have a shorter lifespan of around 15,000 hours, but can last up to 50,000 hours if you choose the LED alternatives.

If you would like to switch out a T5 light for a T8 light or vice versa then you will need to use a ballast. Finding the correct ballast size may also take some effort as there is no industry standard for them. T12 Tube In short, the difference between t5, t8, and t12 lights are the sizes and energy efficiency. The smaller t5 and t8 tubes use less energy and have less mercury in them than T12 bulbs. How do I know which fluorescent light bulb to buy? Despite being an older model, the T12 fluorescent tube lights still offer a range of color temperatures at different watts. However, their limited lifespan of 15,000 hours still makes T12 fluorescent lights a less attractive option compared to the smaller fluorescent tube lights or LEDs. Frequently Asked Questions:

Fluorescent tubes are measured in eighths of an inch, with the measurement being drawn from pin to pin at the end of the tube. The wattage level is dependent on the length of the fluorescent tube. The sizes of fluorescent tubing range from T2 to T17. Production of the largest size T12 (38mm) has ceased. However, they featured the same G13 cap as the T8 tube. This means that it is possible to replace the T12 tube with a more efficient T8 of the same length. T12 fittings use a magnetic start ballast which is less energy efficient. The smaller and newer models have already been fitted with the more energy-efficient electric ballasts. The ballast is what regulates the current to the fluorescent lamps and provides sufficient voltage to start the lamps

As previously mentioned, fluorescent tubes range from the modern T2 to the old style T12. The slim-line T2 tubes feature a W4.3 fitting and a 4.3 mm wide push fitting. T4 tubes are best suited to under-cabinet lighting and have a G5 fitting with 5mm separating the two pins. Standard T8 tubes have a G13 fitting, with 13mm separating the pins. The T12 tubes came complete with the same G13 cap as the T8 tube, meaning that older T12 tubes can be replaced with T8 tubes. Wattage of Fluorescent Tube
