Growers Choice TSL LED PFS SERIES - 40W System, 4 Unit Combo

Low-Profile LED Grow Light for Vertical Farming Racks

The Grower's Choice TSL PFS LED 4-unit combo runs 160 watts total across four 40W bars. Each bar produces 100 µmol/s PPF at 2.5 µmol/J efficacy in the GC-3K Full Phase spectrum. The 1.5 inch ultra-thin housing and 1.0 kg per bar weight target stacked rack vertical farm lighting builds. Inter-tier clearance matters in commercial racks, and these bars keep that clearance tight. Osram top-bin diodes sit on a 47.2 by 5.1 in aluminum profile. Each bar covers approximately 2 by 4 ft of bench space, summing to 8 sq ft per combo. Power factor is greater than 90 percent, so utility billing reflects actual consumption. L90 light maintenance runs greater than 54,000 hours under typical commercial duty cycles.

T5 Fluorescent LED Replacement for Propagation Beds

Growers typically mount the bars at 6 inches above the canopy on cloning beds and seedling trays. They also fit leafy greens and microgreens propagation racks where T5 radiant heat would scorch tender tissue. The 3K full phase spectrum spans 3000 to 3300K with CRI 85 and emphasis at 660nm and 450nm. That spread supports stage transitions from propagation through early vegetative growth in stacked rack vertical farm lighting builds. Passive cooling removes fan noise and a common failure point in tight-tier rack farms. IP65, ETL, and CE certifications cover wash-down cleaning between rotations. The 60 percent HVAC reduction versus comparable T5 setups means cooler rooms with less compressor runtime. Master-cord daisy-chain wiring keeps installs clean across long bench rows. Power factor stays above 90 percent across the 4-bar combo for honest billing.
