How to Replace a Fluorescent T8 Tube by an LED Tube

Even if an LED tube light & a fluorescent tube work in different ways theoretically, an LED tube light is produced to replace a fluorescent tube under the similar shape and measurements. In normal practice, inductive ballast or electronic ballast is required to drive a fluorescent tube; while an LED tube does not need such kinds of ballasts. For example the T8 LED tube light and the T12 LED tube light. In other words, they have different wiring methods.

The circuit structure of the LED tube light requires rewiring the fixture in a practice to replace the fluorescent, which will be very expensive. Very luckily, although the LED light does not need the ballast, it is compatible with the inductive ballast. To follow the safety requirement, almost the LED tubes produced by E-Top (HK) are made the input at the two pins on one end-cap, just like the Oval Tube do. By adding a correct LED shorter, these E-Top tubes can replace the fluorescent tubes in inductive-ballast-based fixtures without rewiring.
