Growers Choice 800W LED Top-Light as a 1000W HPS Replacement
The TSL800W is an 800W LED top-light. It pulls 1,900–2,080 µmol/s PPF at 2.6 µmol/J PPE on the GC-3KF bloom-phase spectrum. It is designed as a 1-to-1 1000W HPS replacement for legacy 1000W DE-HPS fixtures. The 32 lb chassis runs an isolated driver with 0–10V and step dimming at 10–100% range. Certifications include UL 8800, UL 1598, and DLC. Passive cooling, ≥90% driver efficiency at 220V, and a 5-year warranty.
What the 800W Top-Light Brings When Replacing 1000W HPS
Swapping HPS for an 800W LED isn't just an energy savings story. Bloom-phase spectrum from the GC-3KF mix runs cooler at the canopy. Growers typically hang the fixture 6–24 inches above canopy and dim 0–10V across the cycle. Passive cooling means no fan noise and nothing in the airflow path to clean. CRI ≥86 makes mid-canopy inspection easier when walking rows for early bud rot or pest pressure.
Key Features
- 1,900–2,080 µmol/s PPF at 2.6 µmol/J: Bloom-phase flux range on the GC-3KF spectrum, tuned for full-cycle finishing-room performance.
- 1-to-1 1000W DE-HPS Replacement: 800W draw delivers comparable bloom-stage flux while running cooler at the canopy than legacy HPS fixtures.
- 0–10V + Step Dimming: 10–100% dimming range with built-in step modes — covers seedling-to-finish without an external controller.
- Passive Cooling: Fanless thermal management means no moving parts in the airflow path; isolated driver runs ≥90% efficient at 220V.
- 6–24 in Mounting Height: Wide hang-height window covers low-ceiling tents and tall flower rooms with the same fixture.
- UL 8800 + UL 1598 + DLC: Full certification stack for sealed-room compliance, utility rebate eligibility, and commercial install.
- Q90 > 54,000 Hours: Diode degradation curve holds 90% output past 54,000 hours, with a 5-year standard warranty.
