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. 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.
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. The energy efficiency of the T5 tubes means they also last the longest, around 20,000 hours. Compared to a T8, T5 tube can achieve higher luminous flux using less power. On the other hand, T5 tube lights are little powerhouses when comparing T5 vs T8 tube sizes. This is why the T5 is used in many of the same applications. There is not much difference in size between T5s and T4 lights. Be sure to measure the length of the tube and check the wattage before heading for the shops or placing an online order. If you are replacing a T4, you may struggle with finding the same fluorescent light bulbs sizes. They can range anywhere from 6 watts to 30 watts, the lower the number the lower the energy consumption, and many lengths. There is no industry standard for the length or wattage of T4 tube lights. Their size is what makes T4 lights popular for under cabinet lighting purposes and accent lighting for displays or a staircase. T4 tubes are the smallest of the fluorescent bulb sizes, at only 4 eighths of an inch (0.5 in).
Tube Light TypeĪside from the size, you need to check the lighting fixture requirements for being compatible with the bi-pin base type and the milliamps.īut 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. If the size tag is missing, use the overview below for quick reference. So, in most cases, you won’t have to physically measure the tube’s diameter and length. Most tube lighting will have its size mentioned on an end of the tube. The T stands for tubular and the numbers are an index for the diameter (in inches) of the tube. There are 4 different fluorescent light options T4, T5, T8, and T12. What are the different types of fluorescent tubes?.How do I know which fluorescent light bulb to buy?.What is the difference between T5 T8 and T12 lights?.
