Digi-Lumen Halo Dual Spectrum 780W LED Grow Light | UV + Far-Red | 2106 μmol/s | 2.25m² Coverage

Digi-Lumen Halo Dual Spectrum 780W — Full Spectrum + UV + Far-Red for Serious Growers

Not all light is equal. The Digi-Lumen Halo Dual Spectrum 780W goes beyond standard full-spectrum output — adding UVA (395nm) and Far-Red (730nm) diodes to a precision-tuned array of 2364 single-mount LEDs. The result is a light that doesn’t just grow plants — it drives the biological responses that produce denser buds, higher trichome density, and stronger flowering triggers. Covering up to 2.25m² at 2106 μmol/s PPF and 2.7 μmol/J efficacy, this is the Digi-Lumen flagship — built for growers who understand that spectrum quality matters as much as raw output.

Why the Dual Spectrum 780W Is Different

• ✅ UVA 395nm diodes — stimulates trichome and resin production; UV stress response drives higher secondary metabolite output
• ✅ Far-Red 730nm diodes — triggers the Emerson Enhancement Effect; accelerates flowering onset and improves end-of-day light signalling
• ✅ Red 660nm diodes — peak chlorophyll absorption for maximum photosynthetic efficiency during flower
• ✅ 4000K white base spectrum — broad, balanced output supporting healthy growth across all stages
• ✅ 2106 μmol/s PPF at 2.7 μmol/J — high-efficiency output across a full 2.25m² canopy footprint
• ✅ 2364 single-mount LEDs across 6 bars — even, consistent light distribution with no hot spots
• ✅ Integrated 780W driver — all-in-one design; no external driver to mount or cable
• ✅ Die-cast aluminium body — 6.8 kg, built to last 50,000+ hours
• ✅ IP45 rated — reliable in controlled indoor grow environments
• ✅ 2-year warranty — backed by Growers Depot AU

The Science Behind the Spectrum

Standard LED grow lights deliver white and red light. The Halo Dual Spectrum goes further with a precisely engineered 4-channel diode array:

• 2160 × White 4000K — broad-spectrum base for balanced veg and flower growth
• 96 × Red 660nm — peak chlorophyll-a and chlorophyll-b absorption; maximises photosynthetic rate during flower
• 60 × UVA 395nm — activates UV stress responses that increase trichome density, essential oil production, and flavonoid synthesis
• 48 × Far-Red 730nm — triggers the Emerson Enhancement Effect (boosting photosynthesis beyond what PAR alone achieves) and accelerates phytochrome-mediated flowering signals

This combination means your plants receive not just more light — but the right light at every wavelength that drives measurable biological outcomes.

Built for Large Canopy Coverage

At 1100 × 1060mm and just 38mm deep, the Halo Dual Spectrum 780W is engineered for maximum coverage with minimal fixture depth. The 120° beam angle distributes light evenly across a 2.25m² footprint — ideal for 1.5×1.5m grow tents and rooms. The integrated 780W driver keeps the build clean and the installation simple: hang it, plug it in, and grow.
