DLI APEX TOPLIGHT 800FS

Description

DLI Apex Toplight 800FS is a high-output full-spectrum LED fixture engineered for commercial and semi-commercial indoor cultivation, delivering exceptional PPFD uniformity across large canopy footprints. We have been recommending DLI lighting solutions to our customers since 2017, and the Apex Toplight 800FS represents the cutting edge of energy-efficient horticultural LED technology for UK growers.

High-Performance Full-Spectrum LED for Maximum Yield

The DLI Apex Toplight 800FS is built around top-bin Samsung LM301H EVO diodes supplemented with deep-red 660nm and far-red 730nm LEDs that drive peak photosynthesis and the Emerson enhancement effect. The result is a fixture capable of delivering 2.8+ µmol/J efficacy — meaning more light per watt than conventional HPS or older LED designs. Running at 800W, this fixture covers a 1.5m x 1.5m flowering footprint with even, consistent PPFD distribution from edge to centre.

The FS designation indicates a full-spectrum white light output that replicates the broad wavelength range of natural sunlight. This matters not just for yield but for plant health and development throughout the growth cycle — fuller spectrum exposure promotes more robust stem structure, denser internodal spacing, and better overall plant architecture compared to narrow-spectrum blurple LED designs.

Efficiency, Control and Compatibility

The Apex Toplight 800FS includes a dimmable driver with 0–10V control compatibility, allowing integration with environmental controllers for automated light scheduling and intensity management. The low-profile aluminium housing promotes passive heat dissipation and keeps the fixture running cool enough for tight vertical clearances — an important consideration in sealed grow rooms where managing heat load is critical.

Compatible with all growing media and system types. Pair with a quality environmental controller, CO₂ supplementation system, and a balanced nutrient programme to take full advantage of the increased photosynthetic capacity this fixture provides. For growers scaling up from 600W HPS, the Apex Toplight 800FS delivers significantly higher yields with lower heat output and reduced electricity costs over time.
