Do I need supplemental lighting in my climate?

It depends on the gap between the crop's target daily light integral and the natural light your site receives in the weakest months. In high-light regions lighting is often unnecessary and shading matters more; in northern latitudes winter production is usually impossible without it. The calculation, not the region, decides.

Is LED always better than HPS?

LED generally delivers more photons per watt and allows dimming and spectrum control, which matters where electricity is expensive. HPS radiates heat into the crop, which in some cold-climate installations offsets part of the heating requirement. The comparison should be run on total energy cost, not fixture efficacy alone.

How much electrical capacity does greenhouse lighting need?

Installed lighting load per hectare is substantial and is often the single largest constraint on a project. Grid capacity, transformer sizing and connection lead time should be confirmed before lighting is specified, because an upgrade can take longer than the greenhouse build.

What should a lighting quotation include?

Photon flux density at crop level, uniformity across the growing area, fixture efficacy in µmol/J, spectrum, installed electrical load, dimming and control integration, mounting and installation scope, warranty terms and depreciation of output over time.

Does lighting affect climate control?

Yes. Lighting adds heat and changes transpiration, so ventilation, screening, cooling and irrigation set-points all shift. Lighting should be specified alongside the climate package rather than tendered separately.

LIGHTING

Commercial greenhouse lighting systems

Supplemental lighting is bought on light delivered to the crop, not on fixture price. Source LED top light, inter-lighting, photoperiod and control packages specified against your latitude, season and crop light requirement.

SeedMatchGroup helps buyers source greenhouse equipment, agricultural seeds, fertilizers, irrigation systems, pumps, solar systems, drones, cooling systems and complete agriculture project suppliers worldwide.

SeedMatchGroup is supplier-neutral and helps buyers compare greenhouse, seed, fertilizer, irrigation and agriculture project suppliers worldwide. It does not manufacture, distribute or sell equipment or inputs.

How is commercial greenhouse lighting specified?

Greenhouse lighting is specified by the light the crop needs, not by fixture wattage: the target daily light integral (DLI) for the crop, the natural light the site delivers each month, and the installed photon flux density in µmol/m²/s needed to close the gap over a defined photoperiod. From there the specification covers spectrum, uniformity, mounting height, dimming and control, electrical load per hectare and fixture efficacy in µmol/J — the figures that make two offers comparable.

Describe your project (optional)

A few words is enough. The Brief Assistant will expand it into a clear sourcing brief.

The more context you share, the sharper our sourcing shortlist. Nothing is shared with suppliers.

Which packages should the request cover?

Select every package you want included. Anything left unselected is treated as outside the scope, and we will flag it as a possible gap between suppliers. This is equipment and works only — recurring fertilizer supply is requested separately.
