The Flexstar Redline 1000W SpecTune is a commercial-grade, 4-channel tunable LED grow light built around Flexstar’s patented Liquid Optics System (LOS). It delivers up to 2,680 µmol/s at 3.0 µmol/J, with independent UV and Far Red control for stage-specific spectrum recipes while maintaining constant total power.
