The Digi-Lumen Halo 400W delivers 1080 μmol/s PPF at an impressive 2.7 μmol/J efficacy from a sleek 6-bar, 580×580mm fixture — covering your canopy from veg all the way through to harvest without compromise.

Full-Spectrum Performance from Veg to Harvest

The Halo 400W’s full-spectrum output is tuned to support every stage of the plant growth cycle. During veg, the broad spectrum drives strong structural growth and dense foliage. As you move into flower, the same fixture delivers the intensity and spectral balance your plants need for vigorous bud development — no spectrum switching, no fixture swaps, no extra cost.

At 1394 μmol/m²/s PPFD measured at 30cm, the Halo delivers serious intensity at canopy level. Raise the fixture to dial back intensity for sensitive stages; lower it to push harder during peak flower. Combined with the dimmable driver, you have full control over your DLI at every point in the cycle.

Compact Design. Easy Installation.

At just 580 × 580 × 38mm and 3.6 kg, the Halo 400W is one of the most space-efficient fixtures in its output class. The integrated driver keeps the build clean and the installation simple — hang it, plug it in, and grow. The 120° beam angle ensures wide, even coverage without the need for reflectors or light movers.
