LedT was a three-member South Korean rock band formed by Starkim Entertainment in 2010 originally as LEDApple. The band's final lineup consisted of Seo Youngjun (JUN), Lee Kyumin (Kei) and Kim Hyoseok (AKi)

The part "Led" in LEDApple stood for "Logic Egoism Delete" and was promoted during their debut but they stopped referring to it since their CODA mini-album was released. Instead they replaced it with a practical explanation of "shining as brightly as LED whenever they perform" which was eventually referred to as a tribute to their role-model, Led Zeppelin. The word "Apple" in the band's name is supposed to represent their fresh image as idols and fresh music that they release, the name was changed later on August 18, 2015 as they stated to start as LedT from September 1, 2015. As of 2011, fans of LEDApple are officially known as "LEDAs".
