Horticulture Lighting Specifications

Published: September 2026 | Category: Lighting Specifications | Keywords: horticulture LED specs, grow light spectrum, PPFD, plant lighting, LED grow light parameters, horticulture lighting design

1. Overview

Horticulture LED lighting has fundamentally changed controlled environment agriculture (CEA). Unlike general lighting where photometric performance (lux) is the primary metric, horticulture lighting is evaluated by photon flux (PPFD in umol/m2/s) and spectral distribution across photosynthetically active radiation (PAR, 400-700nm). This specification reference covers the critical parameters for Queendom horticulture LED systems.

2. Product Categories

High-Bay Grow Lights

600W-1000W LED grow lights for commercial greenhouses and vertical farms. Replace 1000W HPS systems.

Flat Panel Grow Lights

Slim panel fixtures for multi-layer vertical farming. 100W-300W with close-canopy mounting capability.

Linear LED Grow Lights

T8 replacement and suspended linear fixtures for low-ceiling greenhouses and tissue culture.

Octopus / Spider Lights

Multi-arm fixtures with remote driver for large canopy coverage with minimal shading.

4. Spectrum Configurations

Spectrum Composition Application
Full Cycle (Sunlike) 4000K white + 660nm red + 730nm far-red Complete grow cycle: seed to harvest
Veg (Vegetative) 5000K white + 450nm blue Leafy greens, herbs, vegetative growth stage
Bloom (Flowering) 3000K white + 660nm deep red Flowering plants, fruiting stage
Adjustable (Tunable) Multiple channels independently dimmable Research, phenotyping, custom spectrum

5. DLI (Daily Light Integral) Guidelines

DLI is the total photon flux delivered per day (mol/m2/day). It determines plant growth rate and yield. Target DLI varies by crop:

Crop Type Target DLI (mol/m2/day) Photoperiod
Leafy Greens (lettuce, spinach) 12-17 16-18 hours
Herbs (basil, mint) 10-15 14-16 hours
Tomatoes / Peppers 20-30 16 hours
Cannabis 35-45 18h veg / 12h flower
Microgreens 6-12 12-16 hours
Strawberries 17-25 14-16 hours
