T4 Fluorescent Tube / Bulb 10W

Product Information

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 T8 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. 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). If you are using T5 lights for garage lighting or an art display, then make sure that you choose a model with a higher Color Rendering Index, CRi. The CRi of T5 fluorescent bulbs generally range in the lower end of 70 -80 but there are options with more accurate color rendering up to 95. Basically that means the light color can go from daylight white to extra warm white. 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. 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. 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.

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

T8 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.

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 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.
