Better Light.More Growth.Lower Cost.

Commercial LED lighting and growing systems engineered for exceptional performance, outstanding uniformity, and industry-leading value—factory-direct from GLS.

01 / Featured Products

From New Construction to Retrofit Power Designed Around Your Facility.

GLS moves power away from the canopy and into a controlled server environment—reducing heat, simplifying installation, improving serviceability, and giving growers greater control over every watt and every photon.

01 —

High Efficiency. Lower Operating Costs.

Advanced power conversion and low total harmonic distortion (THD) reduce wasted energy and improve electrical efficiency. Use power more intelligently, lower peak demand, and reduce the true cost of every harvest.

02 —

Server-Grade Performance.

Industrial reliability engineered for cultivation. Remote power architecture enables hot-swaps, maintenance, and routine service outside the grow room—minimizing downtime while reducing unnecessary traffic and potential contamination around your crop.

03 —

Total Control. Maximum Yield.

Deliver the right intensity of light at the right time, giving plants the photons they need throughout each stage of growth. With less heat generated above the canopy, HVAC systems work more efficiently—helping maximize production while reducing cooling costs.

04 —

Pharma-Grade Precision.

Protect high-value crops with consistent, repeatable lighting performance engineered for demanding commercial environments. Maintain tighter control from room to room and harvest to harvest—supporting rigorous production standards and greater batch-to-batch consistency.

04 / Engineered Lighting Design

The GLS Approach

The right light. In the right place. Every facility is different. Every lighting plan should be too.

High photon output is only part of successful cultivation.

Fixture placement, mounting height, spacing, spectrum, and uniformity all influence how effectively light reaches the crop.

GLS uses professional lighting design software to develop customized lighting plans based on each facility's dimensions, growing configuration, and performance objectives.

Whether you're building a new cultivation facility or upgrading an existing operation, our engineering team helps determine the right lighting system for your environment.

Our Lighting Plans Consider:

Target PPFD & Uniformity

The appropriate light intensity and distribution for your cultivation objectives.

Fixture Selection & Placement

The right PROGROW fixtures, mounting heights, and spacing for your growing environment.

Facility Configuration

Room dimensions, ceiling heights, racks, benches, and available growing space.

Power & Control

Local or remote power conversion, dimming, and electrical infrastructure requirements.
