Product Overview

This 12V Full Spectrum PCB LED Grow Light System is a compact, modular lighting solution designed specifically for indoor houseplants, succulent collections, plant cabinets, bookshelf gardens, and propagation trays. Engineered on a slim 300 x 80 mm high-thermal-conductivity aluminum PCB board, each unit integrates 258 to 540 high-efficiency diodes (Samsung, Osram, Sanan, or Epistar options) delivering a photosynthetic spectrum of 3000K warm white, 6500K cool white, and 630nm deep red.

Equipped with a multi-output connector cable and an inline timer controller, the system allows flexible deployment of 1-board, 2-board, 3-board, or 4-board configurations running from a single 12V power supply. The fanless, low-voltage design ensures safe, quiet, and reliable operation directly above plant canopies.

Key Applications & Features

Customizable Multi-Tier Layouts: The 1-to-4 board modular system simplifies shelf wiring by powering up to 4 separate shelves or growing levels with just one wall outlet.
Targeted Horticultural Spectrum: 3000K provides warm light for stem and foliage strength, 6500K simulates midday light to keep internodes compact, and 630nm red fuels active photosynthesis.
Direct Shelf Mounting: The ultra-slim 300 mm aluminum PCB profile attaches easily using double-sided tape, zip ties, or mounting clips underneath shelves and cabinets.
Passive Silent Thermal Control: The aluminum PCB substrate acts directly as the heat sink, dissipating warmth passively with 0 dB zero noise and low thermal impact on plants.
