Plant growth depends on spectrum and photon flux, not on brightness alone. This page introduces general principles of horticultural lighting; Product line documents pending. For horticulture product information, please contact us directly.
Understanding PAR
The following introduces general photobiology principles — not our product specifications.
Plants mainly use visible light between 400 and 700 nm for photosynthesis — this band is called Photosynthetically Active Radiation (PAR). Blue light around 450 nm and red light around 660 nm form the two major chlorophyll absorption peaks, which is precisely the basis of horticultural lighting design.
Spectral curves are illustrative; actual parameters are subject to the formal product datasheet.
Total photons in the 400–700 nm range emitted per second, in μmol/s. It defines the light’s photon output capability.
Photons produced per joule of electricity consumed, in μmol/J. The core metric for luminaire efficacy.
Photons received per unit area per second, in μmol/m²·s. It describes how much light the plant actually receives.
Relative energy distribution across wavelengths. By adjusting SPD, the spectral mix can be optimised for different crops and growth stages.
Horticulture product documents pending
Our official website (www.wx-seastar.com) currently publishes the following product lines: LED LIGHTING and DRIVER AND CONTROL BOARD (ODM/OEM), and has not yet published a horticulture product catalogue, model specifications or photometric files.
This pageWe do not publish unconfirmed models or specifications — documents will be updated here once ready. In the meantime, please request them directly via:
