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 Daisy-chain up to 92 bars on a single run — easy to scale across full rooms OSRAM LED diodes — top-shelf chips, highest efficiency in the industry IP66 sealed — wash-down and humidity safe Passive cooling — silent, no fans, low heat Slim T5 form factor — drops into existing T5 setups, 44.16" L × 1.18" W × 1.18" H 5-year warranty, ETL / TISI / CE certified Sold in 2-pack with 240V cord Specifications Model Wavelength Power Voltage Dimming FR Bar 18W 730nm (Far-Red) 18W 120–277V 0–10V UV Bar 18W 395nm (UV) 18W 120–277V 0–10V Shared Specs Light distribution: 120° Daisy-chain (power): up to 92 lights Mounting height: ≥ 6" above canopy Operating temp: up to 95°F / 35°C IP rating: IP66 Cooling: Passive Certifications: ETL / TISI / CE Warranty: 5 years Dimensions: 44.16" L × 1.18" W × 1.18" H Weight: 0.9 lb / 0.41 kg 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. MIN ORDER ONE FULL PALLET • CONTACT US FOR BULK DISCOUNTS
