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. 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. 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. 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 is a 30w T4 tube that is 762mm long including the pins at each end. It is used in under cupboard lights and some illuminated mirrors. 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. 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.There is not much difference in size between T5s and T4 lights. This is why the T5 is used in many of the same applications. also classified as a warm white, fluorescent tubes featuring this level of colour temperature share lighting properties with halogen lamps 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.

this variety of cool white is typically applied to office buildings. It is also considered suitable for formal home offices 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. 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. 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.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 T12 lamps are the least popular size. This is because they use older technology that is less energy-efficient compared to the smaller options. 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.
