Supplemental Lighting Systems for Commercial Greenhouses
HIGROWSIR plans greenhouse supplemental lighting systems around crop requirements, natural light, target PPFD, greenhouse conditions, fixture layout and project validation.
Why Greenhouses Need Supplemental Lighting
Natural light inside a greenhouse changes with season, weather, location and greenhouse transmission. When the available daylight cannot consistently support the crop target, supplemental lighting is used to fill the light gap and maintain a more predictable growing environment.
The lighting requirement therefore begins with the crop and the available daylight, not with a fixture wattage.

Start with the Crop Light Requirement, Not the Fixture
A greenhouse lighting project should first define the light environment required at crop level. Target PPFD, daily light integral, photoperiod and available daylight provide the basis for deciding how much supplemental light the greenhouse needs.
Fixture power alone cannot answer that question. The same fixture can produce very different crop-level results when mounting height, spacing, optics and greenhouse geometry change.

Design the Lighting System Around the Greenhouse
A supplemental lighting system has to fit the greenhouse geometry and project conditions. Mounting height, bay width, crop rows, structural obstructions, available power and optical distribution all affect how light reaches the crop.
This is why fixture selection, quantity and layout should be considered as one greenhouse lighting system rather than as separate purchasing decisions.

- 03Structural obstructions and hanging positions
- 04Available electrical power

Lighting Engineering
From Target PPFD to Fixture Layout
Once the lighting target and greenhouse conditions are defined, the project moves into fixture layout. Fixture PPF, mounting height, beam distribution and spacing are evaluated together to determine the quantity and arrangement required for the target crop area.
The result is not only an average light level. The layout also needs to be checked for PPFD distribution and lighting uniformity across the growing area.
See how we plan fixture quantity, spacing and light uniformity- 01Target PPFD + Fixture PPF
- 02Mounting Height + Optical Distribution
- 03Fixture Quantity + Spacing
- 04PPFD Distribution + Uniformity
Plan Quantity and Spacing
Evaluate fixture PPF, mounting height, beam distribution and available positions together.
Validate PPFD Distribution
Review average crop-level light and uniformity before the fixture schedule is finalized.
Build the Complete LED Lighting System
The fixture is one part of the greenhouse LED lighting system. After the layout is defined, fixture output, optics, spectrum, dimming strategy, controls and electrical integration need to work together as one project.
HIGROWSIR supports greenhouse projects from fixture configuration and optical selection through control integration and production delivery.

For New Greenhouses and HPS-to-LED Retrofits
New greenhouse projects allow the lighting layout, electrical system and controls to be planned together from the beginning. Retrofit projects start with a different set of constraints, including existing HPS positions, wiring, hanging points and greenhouse structure.
In both cases, the goal is the same: build a lighting system around the crop target and the actual greenhouse, not simply replace wattage one-for-one.
Plan a New Greenhouse System from the Beginning
- Fixture spacing and layout freedom
- Electrical planning
- Controls integration
- Coordination with greenhouse structure
Plan an LED Retrofit Around Existing Constraints
- Existing HPS fixture positions
- Wiring and electrical infrastructure
- Available hanging points
- Structural and layout constraints
Project Evidence
Validated by Real Greenhouse Projects
A lighting plan only matters if it can be translated into a real greenhouse project. HIGROWSIR combines project inputs, fixture configuration and lighting analysis before production and delivery.
Real project documentation, such as greenhouse layouts, PPFD maps and fixture schedules, provides a clearer basis for decisions than fixture specifications alone.
