T4 Fluorescent Tube / Bulb 10W

Product Information

The colour rendering index indicates the ease with which colours can be distinguished on the application of different light sources. A bulb with around 80 CRI may be suitable for common domestic applications. However, you should ensure the fitting of a bulb with a CRI of 90 or more given the need for high levels of light. How Many Lumens are Fluorescent Bulbs? 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

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 fluorescent fittings have been discontinued since 2015 due to EU regulations. The electronics are located in the light fitting and not the tube. If you are finding your lamps are not lasting as long as expected, this would indicate a fault in the light fitting and not the tube - unless the tube is physically smashed it's very unlikely to have a fault. You can test tubes and fittings by swapping tube from another working fitting. Unfortunately manufacturers no longer provide a guarantee for T4 tubes, as the light fittings they are installed into may be approaching the end of their life. 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. There is no industry standard for the length or wattage of T4 tube lights. They can range anywhere from 6 watts to 30 watts, the lower the number the lower the energy consumption , and many lengths. Think about these differences in tube lighting the next time you need to convert fluorescent lighting to LED. The different sizes are not directly interchangeable so if you want to use another size then you will have to do a bit of handiwork. Fluorescent lighting is economical to run and uses long-lasting tubes to provide bright and effective general lighting. T4 fluorescent tubes are ideal for home and commercial use for kitchen worktops, in cabinets, under stairs, as a pelmet lamp, or to create a well-lit workstation for DIY, craft, or commercial use. T5 bulbs are great for large space such as schools, supermarkets, offices, and underground railways. T8 bulbs can be used in schools, garages, offices, conference rooms, retail stores, and most other environments.

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 T12 lamps are the least popular size. This is because they use older technology that is less energy-efficient compared to the smaller options.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? Ideally, there will be legible coding on the fluorescent tube indicating the key characteristics. As an example, you might see the code F32T8. The F in this instance will indicate the fluorescence. The 32 corresponds to the number of watts or length in inches. The T is specific to the tubular shaping. Finally, the 8 corresponds to the diameter in eighths of an inch (this may be represented in millimetres rounded to the nearest millimetre). What Does a Starter Do in a Fluorescent Light? 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 also classified as a warm white, fluorescent tubes featuring this level of colour temperature share lighting properties with halogen lamps

When considering the question of how do I know which fluorescent light bulb to buy you need to figure out what you currently have. Once you have removed the bulb most will be marked with the type on the end, if there are no markings then you can measure the tube diameter to determine their type. What are the different types of fluorescent tubes? The T stands for tubular and the numbers are an index for the diameter (in inches) of the tube. Most tube lighting will have its size mentioned on an end of the tube. So, in most cases, you won’t have to physically measure the tube’s diameter and length. These tubes from Leyton Lighting have plastic end caps that can be removed. This makes the tube slightly shorter which can help with installation into some brands of light fitting.Colour Temperature: usually marked with a K rating on your bulb - you won't need this information now. This is the output color of the bulb and another colour temperature will work in your fitting.

The energy efficiency of the T5 tubes means they also last the longest, around 20,000 hours. However, this is still less than half of the expected lifespan of a T5 LED tube light which lasts an average of 50,000 hours. On the other hand, T5 tube lights are little powerhouses when comparing T5 vs T8 tube sizes. Compared to a T8, T5 tube can achieve higher luminous flux using less power.Another aspect to remember about T5 fluorescent lighting is the different output possibilities. There are three levels of output available on the market; normal output (NO), high output (HO) and very high output (VHO).
