Flexstar - FR / UV Light Bar 18W

Brand: Flexstar

The Flexstar FR & UV Light Bar 18W series adds targeted supplemental wavelengths to any grow room. Use the Far-Red bar (730nm) to accelerate flowering and trigger the Emerson Effect, or the UV bar (395nm) to boost terpene and trichome production in late-flower. Both bars share the same slim form factor and 0–10V dimming so you can integrate them into existing controllers and racks without changing fixtures.

Why the FR / UV Bars?

• Targeted supplemental spectrum — 730nm Far-Red or 395nm UV, no wasted output
• 0–10V dimming — fully controllable, run them on schedules or recipes

• OSRAM LED diodes — top-shelf chips, highest efficiency in the industry

How to Use

Far-Red (FR): Triggers the Emerson Effect to accelerate flowering, shorten cycles, and increase flower density. Most effective during flower-stretch and end-of-day applications.

UV: Boosts THC, terpene, and trichome production in late flower by triggering plant defense response. Use during the final 2–3 weeks of bloom for maximum effect on quality.
