DLI Zenith Series Toplight 900 FS DC

DLI Zenith Series Toplight 900 FS DC

The Zenith Series Toplight 900 FS DC is the latest high-end LED grow light from Dutch Lighting Innovations (DLI). It is designed for professional growers who demand maximum efficiency, superior cooling and long-term reliability.

With its slim, lightweight design, the Zenith fits perfectly beneath climate screens. This reduces light interception and allows more natural sunlight to reach the crop. As a result, growers benefit from lower energy consumption and increased yields.

Optimised Design for Maximum Light

Sunlight remains the most effective grow light. For this reason, the Zenith is engineered to minimise shading inside the greenhouse. Its unique low-profile shape works in synergy with climate screens, reducing total light absorption. Even a small increase in natural light leads to improved efficiency and higher harvest potential.

In addition, the low weight of the fixture simplifies installation and reduces load on greenhouse structures.

Advanced Cooling with Venturi Effect

The Zenith builds on the success of the DLI APEX fixture. However, it takes cooling performance even further. By enhancing the cooling fins and increasing surface area, DLI has strengthened the Venturi effect.

This advanced airflow removes up to 30% more heat. As a result, LED temperatures remain lower. This improves light output, increases efficiency and significantly extends fixture lifespan.

High-End OSRAM Top Bin LEDs

To maintain exceptional performance, DLI uses only latest-generation OSRAM Top Bin LEDs. These premium LEDs degrade by just 1% per year. In comparison, lower-grade LEDs can lose 25–50% output annually.

By choosing Top Bin LEDs, growers avoid frequent replacements and maintain consistent, high-quality light output over many years.

Wireless Dimming and Control

The Zenith supports wireless dimming and control via DLI multi-group dongles. Fixtures connect easily to a multi-zone mesh network. Growers can group and control lights exactly as required.

Because the system is wireless, no costly changes to cabling or electrical panels are needed.

Controllable Far-Red Options

The Zenith is available in multiple spectra, including far-red options. Single-channel versions dim PAR and far-red together. Dual-channel versions allow independent control of far-red light.

This flexibility is ideal for crops that require far-red only at specific stages, such as after the main lighting period ends.
