Product Description
The Grower's Choice TSL-800 is an 800-watt LED grow light engineered as a true one-to-one replacement for 1000W HPS fixtures. Producing up to 2080 µmol/s under the GC-3KF bloom spectrum across a 4x4 to 5x5 ft footprint, it drops straight into existing HPS room layouts — same light plan, less power, far less heat. Its patented passive thermal design cools without fans, and a patented diode arrangement concentrates PAR where the canopy needs it.
Key Features
- Direct 1000W HPS replacement – keep your room layout and fixture spacing while cutting power draw by roughly 20%
- Up to 2080 µmol/s, GC-3KF bloom spectrum – flowering-optimized full-spectrum output
