T4 Fluorescent Tube / Bulb 10W

Product Information

also classified as a warm white, fluorescent tubes featuring this level of colour temperature share lighting properties with halogen lamps

categorised as an extra warm white, this colour temperature is typically featured in fluorescent tubes designed for domestic use These light sources are unusual, smaller fluorescent fittings that were previously installed in a variety of different applications to provide customers with bright general lighting in homes, commercial properties, or offices. Although they aren’t as common anymore, you may still have existing fittings that need replacing. If you’re looking to replace a current fitting in a unit you’ve already got, we have a wide selection of T4 tubes. Once considered most effective in large spaces, like schools and supermarkets, fluorescent tubes were also found to be just as effective in smaller spaces like garages, conference rooms or simply under your stairs at home. Wherever your fitting is, we provide a vast selection to accommodate what you’re looking for.

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? 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? 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

This 30w bulb is 748mm long excluding pins and 762mm long including pins. The manufacturer specifies a tolerance of +/- 2mm for these tubes. T4 tubes have an impressive lamp life of up to 10,000 hours and require a lot less energy to produce light compared to traditional light bulbs, in fact, fluorescent lamps save 60% on energy usage compared to incandescent lights. There are still so many existing T4 fittings out there that constantly need replacing, but as they decrease in popularity, it can be hard to find the right replacement. At BLT Direct, we’ll help you to find the right fitting you need to instantly re-energise your space. Whether you used your fluorescent light to highlight a certain area of your house or brighten up your workspace to boost productivity, we have a range of sizes that are ideal in any environment. 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. Both the colour temperature and colour rendering index will have a bearing on the appropriate choice of fluorescent tubing. The colour temperature corresponds with the warmth of the light. Warmer tones will have a yellowish appearance, while cooler shades will be relatively bright. 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.

T12 lamps are the least popular size. This is because they use older technology that is less energy-efficient compared to the smaller options. 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?

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. The watts needed for T5 lighting will increase with the type of output. For example, a NO-T5 tube light can range between 14 watts to 35 watts while an HO-T5 fluorescent tube light will usually range between 24 watts and 80 watts. T8 Fluorescent Lighting 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 TubeT8 lights are commonly used in larger spaces as overhead lighting for example in office spaces with troffer lights, garages or classrooms. This is why you will often see long T8 lighting in 4 foot light tubes, 6 feet, and 8 feet lengths. 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. The number of watts will be indicated after the F on the fluorescent tube. As an example, an F8 tube with 24 watts will have the number F24T8. The level of light output will also have a bearing on the wattage of the fluorescent tube. The efficacy of the fluorescent tube will range from around 16 lumens per watt for a 4-watt tube with a regular ballast to more than 100 lumens per watt for a tube featuring a modern electronic ballast. The level of light emitted from the fluorescent tube is also affected by the lamp temperature in the coldest area of the lamp. Fluorescent Tube Choices by Size 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 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.

this variety of cool white is typically applied to office buildings. It is also considered suitable for formal home offices 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. 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. coming under the category of bulk standard white, this colour temperature is considered suitable for a wide variety of commercial purposes 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 LightsT8 lights are a good choice for an adjustable lighting system because of their color temperature range from a soft yellow-white to bright daylight. You will also have several options that you can connect to a dimmer. 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. 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? Fluorescent tubes fall under the classification of hazardous waste due to their mercury content. Care should be taken during the disposal process as part of your commitment to environmental and legal compliance. It will be important to switch off the power source before detaching a fluorescent tube. The tube may then be wrapped in paper or towelling to prevent breakage. The tubing can then be transferred to recycling or hazardous waste disposal in accordance with the legal requirements. What Do the Numbers Mean on a Fluorescent Tube?
