HarryA Posted February 16, 2020 Report Share Posted February 16, 2020 The photographs show the working end of a 24 inch LED tube light. This type of light only requires connections to one end. No ballast is required for this light. The light yellow device at the lower right is the transformer. Next to it is a yellow capacitor. On the bottom the larger three leaded component is labelled: SDL2N65UZ. There are 72 LEDs in the strip. The LEDs are arranged in pairs in parallel so there are 36 pairs in each strip. An 82 volt battery will light the first 30 pairs with a current of 44.9 milliamperes. White LEDs are rated 3.6 volts at 20 milliamperes.
