Rubol’s Josephine 48W Red/Far Red is a compact LED COB spot intended for supplemental horticultural lighting, adding deep‑red and far‑red wavelengths for dawn/dusk simulations or spectrum tuning during flowering. The unit uses a Citizen CLU048‑1212C4 COB and is commonly paired with a ~90° reflector to shape its beam. Growers have reported deploying it as a targeted add‑on above canopies to stimulate rapid leaf “wake‑up” at lights‑on and modestly heavier flowers directly under the spot when used alongside primary white LED fixtures. As a supplemental spot rather than a stand‑alone grow lamp, its effective coverage depends on mounting height and aiming.
