Lee Sang Hyun, known professionally as Q.L, is a South Korean singer, dancer, and former member of BTL (비티엘).

He made his debut in May 2014 as the group's vocalist with their first single, "Beyond The Limit".

The group was managed by Shinhoo Entertainment (신후이엔티; formerly known as Kiroy Company) but faced many financial and logistic issues after Kiroy merged with SI Entertainment and acquired Shinhoo (keeping that name) in mid-2015. The group did not release any new material after their debut, as their mini-album "Gold Moon" was completed but went unreleased when the agency went broke and closed down. They disbanded in April 2016.

He briefly reunited with 3 other groupmates for the singing survival show "Peak Time" in 2023 but was unsuccessful. He remains out of the entertainment industry.
