Three wattages — 760W, 1000W and 1200W XL
Everything the Redline does, plus four independently controlled channels — White, Deep Red, Far Red and UV. Far Red and UV adjust from 25% to 100% without dropping main-channel power, so a light recipe can change by growth stage rather than by fixture.
SpecTune runs four channels you control independently — White, Deep Red, Far Red 730nm and UV 395nm. Drag a channel or pick a stage below to see the curve change. Far Red and UV adjust from 25% to 100% without dropping main-channel power.

Specifications as published by Flexstar in the Redline SpecTune brochure (2025 release). All models: 120–277V, IP66, 54,000-hour LED lifetime (Q90), RS485 dimming with daisy-chain group control. UV and Far Red channels adjust independently from 25% to 100%.
White, Deep Red, Far Red and UV each control separately, so UV and Far Red can move without touching main-channel output.
Run a full-spectrum vegetative recipe, then bring Far Red and UV in for flower — on the same fixture.
The same silicone-sealed lens as the Redline: 14% more PPFD, 5–8°C cooler LEDs, and a wipe-clean sealed face.
RS485 dimming over a waterproof port with daisy-chain group control across the room.
