Product description
Hortimol MXH4 LED 330W FSM+ 2.5 µmol/J LED Grow Light: lighting and specifications
The MXH4 combines an advanced full spectrum with energy-efficient LED technology and a modular design. The FSM+ spectrum (Full Spectrum Mixed Plus) combines 450 nm blue for compact growth, 660 nm red for vigorous flower formation and 730 nm far red for improved light penetration into the canopy. The warm white 3,200 K colour temperature provides a sun-like light profile that maximises plant vitality and productivity.
With a power draw of just 330 W, the MXH4 produces a PPF of approx. 825 µmol/s and delivers strong output for energy-optimised indoor setups, small grow tents and vertical systems. The passively cooled, flat construction allows completely silent use – ideal for discreet or noise-sensitive environments.

Product description / product details
Effect & properties
The MXH4 delivers a sun-like full spectrum that supports photosynthesis, growth and flowering alike. Far red (730 nm) accelerates physiological processes such as stretch and flower development, while blue components promote a compact, sturdy plant structure.
The open, modular design guarantees maximum light transmission and allows flexible use – on its own or linked. Thanks to IP65 certification, the fixture is protected against moisture and dust.
