LUMEN (Group)
Active · Resident of Project REPLICA
LUMEN are Dohyun, Siwoo, Jaehyuk and Hojun, four Seoul-based idols whose different registers resolve into one signal. Warm tenor, airy high light, melodic rap and choreography carry a shared cosmic-romantic world about connection finally arriving across distance.
The Group's members are Dohyun / Seo Do-hyun, Siwoo / Lee Si-woo, Jaehyuk / Park Jae-hyuk, Hojun / Kim Ho-jun. It is active from 2026–present as a resident of Project REPLICA on FARA Records.
Origins
The final line-up emerged during a concept evaluation built around distance and signal. Dohyun gave the material a centre, Siwoo supplied its high light, Jaehyuk connected the narrative sections and Hojun made the chorus legible in movement. The four were kept together because removing any one function broke the idea.
The source anchor for the Group is: Four development routes—family/vocal academy, quiet upper-register discovery, cyphers/dance crews and competition dance—resolve into one four-register signal. No exact line-up-lock date is supplied.
Formation and member roles
Dohyun is leader/main vocalist; Siwoo lead vocalist/visual; Jaehyuk main rapper; Hojun main dancer, performance centre and sub-vocalist.
Dohyun resolves practical tension, Siwoo notices atmosphere, Jaehyuk releases pressure with humour and Hojun turns care into action. Leadership stabilises the group but does not erase four equal narrative roles.
Musical style and method
LUMEN works across K-pop, idol pop, dance-pop, R&B, hip-hop, EDM.
Each song receives a four-part register map before detailed arrangement: centre, light, motion and physical hook. Members rotate small initiating moments while the full formation remains the payoff.
The recurring themes are light crossing distance, arrival, connection, signal, night sky, recognition.
Public image
A single distant point of light separates into four member colours, then reforms as one beam at the final chorus. Choreography emphasises arrival and recognition rather than militaristic formation.
Deep-night indigo, silver starlight, one warm gold beam, chrome/glass reflection and individual member light accents.
Extend the cosmic world into observatory glass, wet Seoul rooftops, dawn buses and film-camera skies; keep faces warm and human inside the high-gloss frame.
AURA Live
