The Flexstar Redline SpecTune is the tunable-spectrum flagship of the Redline series — built for cultivators who need scientific control over plant responses. Breeders, R&D facilities, craft cultivators, and high-margin commercial rooms use SpecTune to dial spectrum recipes per strain, optimize terpene and cannabinoid profiles, and run repeatable growth protocols. SpecTune sits on the same patented Liquid Optics System (LOS) platform as the standard Redline, so you get the same industry-leading 3.2 μmol/J efficiency, IP66 sealing, and 54,000-hour lifespan — plus four independently controllable channels (White, Deep Red, Far-Red, UV) for true spectral command. SpecTune Technology — 4-Channel Independent Control Main Spectrum (White + Deep Red): dynamically tunable from vegetative through flowering Far-Red channel: 0% / 25%–100% — accelerates flowering, shortens cycles, enhances flower density UV channel: 0% / 25%–100% — boosts THC and terpene production for premium-quality flower RS485 + 0–10V control: integrates with controllers and centralized data systems Constant-power dimming: spectrum integrity preserved across all dim levels Why Redline SpecTune? 3.2 μmol/J PPE on main spectrum, 3.1 μmol/J BPE on broadband spectrum Liquid Optics System — 99% optical efficiency, no yellowing, sealed light bars Bidirectional silicone-gel cooling reduces LED temps by 9–15°F IP66 rated — sealed against dust, humidity, pesticide mist, and wash-down 54,000-hour Q90 lifespan — 5-year warranty, no maintenance required Recipe-driven programming for repeatable, science-backed cultivation Free power cord included (specify 120V / 240V / 277V at checkout) Backed by 15+ years of Flexstar manufacturing experience SpecTune Model Specifications Model Total Power Channel Breakdown Bars Coverage PPF (400–700nm) BPF (380–800nm) 760W ST 760W Main 645W + FR 75W + UV 40W 6-bar 4 × 4 ft 2060 μmol/s 2320 μmol/s 1000W ST 1000W Main 840W + FR 105W + UV 55W 8-bar 4 × 4 ft 2680 μmol/s 2900 μmol/s 1000W ST XL 1000W Main 840W + FR 105W + UV 55W 8-bar 4 × 6 ft 2680 μmol/s 2900 μmol/s 1200W ST XL 1200W Main 1000W + FR 140W + UV 60W 10-bar 4 × 6 ft 3200 μmol/s 3480 μmol/s Independent UV & Far-Red — Why It Matters UV Light: Boosts THC and terpene production. Trigger plant defense responses to increase potency and overall crop value. Far-Red Light: Accelerates flowering via the Emerson effect, shortens growth cycles, and enhances flower density for bigger, better yields. Independent 0%/25%–100% control of each channel means you can run a 4-channel spectrum recipe per strain, per stage, with the controller dialing UV and Far-Red without affecting main-channel output. Built for Commercial Grow Rooms LOS-sealed light bars protect diodes from direct hose sprays, pesticide mist, and harsh cleaning chemicals. Passive cooling — no fans, no airflow noise, no dust accumulation — maintains optimal junction temps up to 35°C / 95°F. Wipe-and-go cleaning means you can sanitize and maintain the grow room without interrupting the cycle.
