Scynce LED

Patented Optics That Work at Every Hang Height

The core of Scynce LED's engineering philosophy is that precise photon delivery should not depend on hang height or canopy distance. By engineering secondary optics — not just LEDs — into every fixture, Scynce ensures that intensity gradients, bleaching, and dark corner problems are solved in hardware, not workarounds. That design discipline translates directly into measurable yields and repeatable results across every grow format, from multi-tier vertical racks to commercial high-bay installations.

Full-Power Spectrum Tuning Without Compromise

Most multi-channel fixtures dim the remaining channels when any single channel runs at reduced power. Scynce LED's architecture redistributes that power — meaning growers retain 100% of fixture wattage at every spectrum setting.

• Four independently tunable channels: The Raging Kush 2 and Dragon Alpha 2 both run warm white (2700K), cool white (6500K), and a red/far-red channel — each independently controllable without any penalty to the others. Growers can hold full veg-spectrum intensity while introducing peak bloom red, or flip the entire fixture to a warm end-of-flower profile, all at full rated wattage.
• OVERDRIVE mode for peak-DLI applications: The Raging Kush 2 pushes total fixture PPF from 1,631 µmol/s in standard mode to 2,251 µmol/s when OVERDRIVE engages — a meaningful boost for cultivars targeting high daily light integrals without adding fixtures or increasing room count.
• IP66-rated passive cooling on vertical fixtures: The Raging Kush 2 and Raging Kale 2 are fully sealed against water jets and dust — no fans, no moving parts, no maintenance requirements in high-humidity flowering and clone rooms. The Dragon Alpha 2 adds an IP67-rated active cooling fan for its longer hang-height range.

Matching the Right Fixture to Your Canopy

Scynce LED's three-fixture lineup covers distinct grow formats — selecting the right model means matching optic geometry to canopy geometry, not just matching wattage to square footage.

• Vertical racks and tight multi-tier systems: The Raging Kale 2 (250W) is 2.5 inches tall and 12 pounds — engineered for multi-level racks where fixture height and weight are hard constraints. Its Conic 120° optic maintains even intensity down to 6 inches, covering up to 5'×4' for veg and clone. For flowering in the same vertical format, the Raging Kush 2 (650W) uses the identical optic geometry at higher output, covering 4.5'×4.5' at 40W per square foot. Need dedicated veg lighting?

• Single-level warehouse, greenhouse, and high-bay grows: The Dragon Alpha 2 (650W) swaps the Conic optic for a Linear 70° lens — purpose-built for hang heights between 24 and 72 inches. At 30 inches above a 5'×3.5' flower footprint, it delivers 1,195 µmol/m²/s average PPFD at 2.48 µmol/J efficacy. Growers targeting high-DLI applications can push that to 1,492 µmol/m²/s over a tighter 4.5'×2.75' footprint. For more high-output options at this power level, the 700W LED grow lights category covers comparable fixtures from other brands.

• Ecosystem tip — THEIA control infrastructure: Every Scynce fixture connects to the THEIA control ecosystem. The Theia Echo acts as the wireless hub — accepting up to five 0–10V inputs from environmental control systems and broadcasting spectrum, intensity, and schedule commands to up to 10,000 fixtures simultaneously. Growers who need remote monitoring from off-site can add the Theia Echo Air; those prioritizing schedule continuity during power failures should consider the Theia Tempo, which adds a built-in battery backup to keep lighting schedules running through outages.

Getting the Most Out of Scynce LED Fixtures

Scynce LED's optic and control architecture rewards growers who treat the THEIA system as an active tool, not a set-and-forget timer. Leveraging the full control range consistently produces better results than running any fixture at a fixed output.

• Stage the spectrum, not just the schedule: Use the THEIA App to shift the 6500K/2700K ratio gradually through the grow cycle — cooler spectrums during early veg to promote compact branching, a warming curve through pre-flower to signal the shift, and peak red/far-red contribution during the final weeks of flower. All channels hold full power through every transition.
• Calibrate hang height to life stage: For Conic 120° fixtures (Raging Kush 2 and Raging Kale 2), the supported 6–18 inch range is performance-tested across that full span — growers can raise fixtures to reduce PPFD during propagation and lower them incrementally as plants develop, without recalibrating spectrum or intensity settings.
• Use the dim-to-off function for sunrise/sunset ramping: The 10%–100% dimming range with dim-to-off capability allows for true photoperiod simulations. Scheduling gradual ramps at lights-on and lights-off reduces plant stress and can measurably improve stretch response during the transition to flowering.
