A full spectrum quantum board is one of the simplest ways to give cannabis plants even, high-output light without the heat and noise of older HID fixtures. The board pairs a dense LED array with a wide, low-profile aluminum heatsink, so light spreads across the canopy instead of concentrating in one hot spot. It is a plug-and-play upgrade that fits most standard grow tents and works from clone through harvest.

Key Features
- Full-spectrum diode mix of white, 660 nm deep red, and 730 nm far-red for veg through flower
- Dimmable constant-current driver with smooth 0 to 100 percent output control
- Fanless aluminum heatsink for silent operation with no moving parts
- Even PPFD spread across a 4 x 4 ft veg footprint and a 3 x 3 ft flowering footprint
- Pre-drilled corners, adjustable rope hangers, and daisy-chain ports for multi-board rooms
- Waterproof push-in connectors and a conformal-coated board for humid grow spaces
- Flicker-free output rated for roughly 50,000 hours of use
The fixture is built on a 2 mm aluminum-core PCB with high-bin white and red diodes, a dimmable constant-current driver, and sealed connectors. At full power it draws about 240 W and runs on 120 to 240 V, hanging 18 to 24 inches above the canopy in veg and 12 to 18 inches in bloom. The passive heatsink keeps surface temperatures low enough to hang without ducting or extra fans.
how far should grow lights be from cannabis plants
What does full spectrum mean for cannabis?
It means the board emits a broad, continuous range of wavelengths, including white light plus added deep red and far-red, rather than only narrow blue and red spikes. That wider mix supports steady vegetative growth and dense flower development under a single fixture.
How high should I hang the quantum board?
Start around 24 inches above the canopy in veg and 12 to 18 inches in flower, then adjust to how the plants respond. If leaves bleach or stems stretch toward the light, raise the fixture or turn the driver down.

How many boards do I need for my tent?
One board comfortably covers a 3 x 3 ft flowering area or a 4 x 4 ft veg area. For a 4 x 4 bloom room or larger, plan on two boards daisy-chained for even coverage.
