The difference between the tube T8 and T5

- Nov 29, 2017 -

1. Calculation method:

T8 Diameter = T * 8 = 1 inch = 26MM

T5 Diameter = T * 5 = 5/8 inches = 16MM

T = 1/8 inch.


2. The difference between luminance and energy-saving :

As T5 diameter than T8, T12 lamp diameter is much thinner, lamp-filled inert gas atoms and electrons have a higher probability of elastic collision, energy loss smaller, which is also very beneficial to improve the luminous efficiency. Because of the inert gas is a unique mixture of inert gas, not only to better protect the cathode of the lamp and help the lamp take off, but also can properly reduce the lamp pressure. Further improve the luminous flux output. Therefore, although the power of the lamp is lower, the total luminous flux does not decrease, so the luminous efficiency of the lamp is improved. That is to say, the T5 is brighter and more energy efficient than the T8.


3.The difference between the length:

The average T5 lamp is shorter than the T8 lamp 5CM (length is not the same, the interface is not the same), so we have to make the project to transform the lamp size to take full account of the lamp panel is used if the T8 lamp panel for energy-saving retrofit LED, you can directly put LEDT8 lamp, if you want to change the T5 lamp more energy, then you need to add the conversion bracket can be loaded up. However, please note that if you use the T5 lamp panel for energy-saving transformation, it can not be replaced with LEDT8 lamp, because it can not be installed, unless the replacement of the lamp panel, but this cost is too large, it can only Replace with LEDT5 lamp. ——Yeslinkele.com
