Five wattages — 400W to 1000W XL
The Liquid Optics silicone-sealed lens system delivers 14% more PPFD and lowers LED temperature by 5–8°C. Every Redline runs 3.2 μmol/J with a consistent spectrum through the full dimming range, built-in drivers and a foldable body.
Every Redline ships the fixed R5W spectrum — a broad white base with heavy deep-red weighting for flower. It holds its shape through the whole dimming range, so a fixture at 50% is the same light as one at 100%. Need the spectrum to change by growth stage instead? That is the SpecTune series.

Specifications as published by Flexstar in the 2025 product catalogue. All models: 120–277V, IP66, 54,000-hour LED lifetime (Q90), 0–10V dimming with daisy-chain group control.
A silicone layer between LED and lens cuts refraction for 14% more PPFD, with bidirectional cooling holding LEDs 5–8°C lower.
A fully sealed lens keeps dust, humidity and fertiliser spray off the diodes. Sanitise and wash the room without interrupting the grow.
The spectrum holds steady across the whole dimming range, so a dimmed fixture is not a different light.
Drivers are on board and the body folds, which cuts installation time and the cable count overhead.
