Who This Is For

You are switching to high bay fixtures because your current lights create hot spots when hung at seven feet.
You are adding independent red control because you need to steer crop development without losing total light output.
You are moving to app based scheduling because manual timer adjustments in a large room are eating up your mornings.

What We Found

The 70 degree optic lens is the real star here because it pushes light sideways into the canopy instead of just down.
We noticed the Echo Air controller makes a huge difference if you hate fiddling with phone apps in a crowded room.
The active cooling fan is surprisingly quiet for an IP67 unit even when the room hits peak daytime temperatures.

What Users Say

Greenhouse operators say the narrow profile blocks less sunlight while providing the massive boost they need in winter.
Growers who switched from fixed spectrum LEDs say the tunable red channel let them control plant height more reliably.
Facilities running the THEIA app report they saved hours of manual work by scheduling sunrise and sunset ramps.

Scynce LED Dragon Alpha 2 Full Spectrum LED Grow Light

Single-level warehouse rooms and high-bay greenhouse structures need an LED grow light that can hang high, cover wide, and still deliver professional PPFD numbers — without forcing a trade-off between output and spectrum control. That's the problem the Dragon Alpha 2 is built to solve. For growers with lower vertical clearance, the Scynce LED Raging Kush II offers a similar level of control in a tighter form factor.

Scynce LED's flagship high-bay fixture runs 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 at any dial position. The patented Linear 70° optic delivers consistent, uniform light from 24" to 72" above canopy, eliminating the hot spots that plague conventional reflector-based fixtures at height. Spectrum, intensity, and scheduling are fully programmable via the THEIA App or a wireless controller like the Scynce Theia Echo Air LED Controller.

Over a 5'×3.5' flower canopy at 30", the Dragon Alpha 2 averages 1,195 µmol/m²/s PPFD at 37W per square foot — scaling to 1,492 µmol/m²/s over a tighter 4.5'×2.75' footprint for high-DLI applications. Fully sealed to IP66 with an IP67-rated active cooling fan, certified UL/CSA/CE/FCC/RoHS/DLC, and compatible with 120V through 277V. For veg and mother room stages, pair it with the Scynce LED Raging Kale II, or explore the full Scynce LED grow light range to find the right fixture for every zone in your facility.

Spectrum

Scynce LED Dragon Alpha 2 canopy coverage view

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 for complete photoperiod control.

PPFD

Scynce LED Dragon Alpha 2 Linear 70 degree optic

Using the Linear 70° optic at 30" above canopy, the Dragon Alpha 2 averages 1,195 µmol/m²/s over a 5'×3.5' flower footprint at 37W per square foot. For high-DLI applications requiring maximum photon density, tightening the array to 4.5'×2.75' pushes average PPFD to 1,492 µmol/m²/s at 52W per square foot. The 24"–72" hang height range makes it equally at home in low-ceiling tent grows and tall single-canopy warehouse configurations.

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

FAQs

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", the Dragon Alpha 2 delivers an average of 1,195 µmol/m²/s PPFD at 37W per square foot. For high-DLI applications, tightening to a 4.5'×2.75' footprint pushes average PPFD to 1,492 µmol/m²/s at 52W per square foot.

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.
