LumiFlora Undercanopy 300W LED – Powerful Underlighting

Professional full-spectrum undercanopy lighting for dense plant canopies & vertical grow systems

The LumiFlora Undercanopy 300 W LED is the big sister to the 150-watt version and was specifically developed to provide intense light to the lower parts of plants.
With 840 µmol/s PPF and a spectrum of 3500 K white light & 660 nm deep red, it provides optimal conditions for photosynthesis, flower development, and a compact plant structure.

Its slim, modular design with IP65 protection and passive cooling makes it the ideal choice for professional growers who aim for maximum efficiency and uniform illumination throughout the entire plant stock.

✅ Advantages at a glance

✅ Perfect addition to top & side lights
✅ Slim, robust & waterproof IP65 design
✅ High efficiency: 2.8 µmol/J at 300 W
✅ Passively cooled – silent & maintenance-free
✅ Daisy-chain connection – up to 10 modules connectable
✅ Plug-and-play installation in minutes

💡 Full-spectrum technology for maximum photosynthesis

The precisely tuned light spectrum ensures that even the lower parts of the plants – often in the shadow of the upper canopy – are evenly illuminated.
This results in stronger side shoots, fuller inflorescences, and uniform growth at all levels.

The deep red light (660 nm) stimulates flowering, while the white 3500 K light provides a natural, broadband spectrum for strong vegetative phases.

🛠️ Application & Notes

1️⃣ Ideal as undercanopy lighting for large plant canopies and vertical systems
2️⃣ Can be mounted horizontally or vertically – flexible for use under canopies or from the side
3️⃣ Daisy-chain connection possible (up to 10 modules)
4️⃣ Recommended distance to plant: 25–45 cm
5️⃣ Combination with top or side lights for maximum yield increase

💡 Tip: Particularly effective in combination with the LumiFlora Fold series to achieve a consistently homogeneous light profile throughout the grow space.
