T4 Fluorescent Tube / Bulb 10W

Product Information

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. 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: This 30w bulb is 748mm long excluding pins and 762mm long including pins. The manufacturer specifies a tolerance of +/- 2mm for these tubes. 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? 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.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. 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 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.

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 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 SizeFluorescent 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? 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.
