Josephine 135W Citizen is a compact single‑COB horticulture LED from Dutch maker Rubol, built around a Citizen CLU058 COB package. The 135‑watt variant is positioned for small indoor grow spaces and has been recommended by community users for roughly 60×60 cm tents, offering a concentrated footprint typical of high‑output COB spot fixtures. Rubol sold this model as both a DIY kit and plug‑and‑play option; community listings explicitly reference the Citizen CLU058 V2 LED used in this configuration. While detailed factory specifications are limited publicly, multiple independent sources confirm the 135 W power class and Citizen chipset for the Josephine line.
