Who This Is For

Growers managing multi-zone facilities who need to adjust spectrum output without swapping out entire lighting arrays
Operators in high-bay or warehouse settings who require deep canopy penetration at hang heights exceeding 24 inches

What We Found

The linear optics focus photons vertically, which keeps the intensity consistent across the edges of the footprint.
We tell growers to use the red channel boost late in the cycle to push density without needing additional fixtures.

What Users Say

Commercial operators who integrated the wireless controller say they saved hours on weekly light scheduling tasks.
Growers who swapped to these fixtures report that the consistent canopy depth allows for more uniform plant height.

Scynce LED Dragon Alpha 2 Full Spectrum LED Grow Light

Most grow lights force you to choose between power and control — the Dragon Alpha II eliminates that trade-off entirely. Scynce LED's flagship fixture delivers 650W of white-channel output across independently tunable 2700K and 6500K channels, paired with a dedicated 160W red/far-red channel switchable between 660nm and 720nm — all without sacrificing a single watt of output at any dial position. Over a 5'×3.5' flower canopy, the Alpha 2 averages 1,195 µmol/m²/s PPFD at 30 inches, making it a professional-grade alternative to the Scynce LED Raging Kush 2 Full Spectrum LED Grow Light for single-level warehouse, high-bay, and greenhouse applications.

Spectrum & PPFD

The Dragon Alpha 2 runs four independently controlled channels — warm white (2700K), cool white (6500K), deep red (660nm), and far-red (720nm) — with no power penalty at any combination. The white channels blend continuously across the full photosynthetically active range, while the red/far-red channel can be split evenly between wavelengths, weighted toward either, or shut off entirely. Using the 70° Linear optic at 30" above canopy, the fixture averages 1,195 µmol/m²/s over a 5'×3.5' flower footprint at 37W/sf, scaling to 1,492 µmol/m²/s over 4.5'×2.75' for high-DLI applications.

Warranty

The Dragon Alpha 2 is backed by Scynce LED's 5-year warranty. Coverage does not extend to operator abuse or error.

📄Dragon Alpha 2 Spec Sheet

FAQ

What spectrum channels does the Dragon Alpha 2 have, and can I control them independently?+

The Dragon Alpha 2 features four independently tunable channels: white 2700K (warm), white 6500K (cool), red 660nm, and far-red 720nm. Each channel can be set to any intensity — including fully off — without any loss of power on the remaining active channels.

What is the flower canopy coverage and average PPFD?+

Over a 5'×3.5' flower footprint with the array hung at 30 inches, the Dragon Alpha 2 delivers an average of 1,195 µmol/m²/s PPFD at 37W per square foot. For high-DLI applications requiring 1,200–2,000 µmol/m²/s, Scynce recommends contacting their design team directly at sales@scynce.ag.

How high can I hang the Dragon Alpha 2?+

The Linear 70° secondary optic allows the Dragon Alpha 2 to be hung anywhere from 24" to 72" above the canopy while maintaining consistent, uniform light intensity. This wide range makes it equally suited for low-ceiling tent grows and tall warehouse or greenhouse configurations.

How do I control the Dragon Alpha 2?+

The Dragon Alpha 2 supports both wired and wireless control of spectrum, intensity, and scheduling. It is fully compatible with the THEIA App for remote programming — including sun-simulation dimming curves and strain-specific spectrum profiles — as well as the Scynce Theia Echo Air LED Controller for wireless multi-fixture control.

What does the IP66 rating mean, and is it safe in humid grow environments?+

An IP66 rating means the entire fixture is sealed against powerful water jets and dust ingress — making it well-suited for humid greenhouse and commercial grow room conditions. The active cooling fan carries an independent IP67 rating, meaning it can withstand brief water immersion without damage.

What input voltages does the Dragon Alpha 2 support?+

The Dragon Alpha 2 is compatible with 120V, 240V, and 277V supplies with a power factor above 95%. It ships with NEMA 5/15, 6/15, or 7/15 plug configurations, or with flying leads for direct panel wiring in commercial installations.

What warranty does the Dragon Alpha 2 carry?+

Scynce LED backs the Dragon Alpha 2 with a 5-year warranty. The warranty does not cover operator abuse or error.
