FloraFlex High Bay 680W LED Grow Light | 1,836 umol/s | 4×4

FloraFlex High Bay 680W LED Grow Light with 1,836 µmol/s PPF

The FloraFlex High Bay 680W LED Grow Light delivers 1,836 µmol/s PPF at 2.7 µmol/J. It gives hydroponic growers high-output photon delivery across a tight 4×4 ft canopy. The custom full-spectrum and red diode mix carries plants from seedling through bloom finish on a single fixture. Fanless passive cooling keeps audible noise out of small rooms where every fan watt adds heat.

Full Spectrum LED Grow Light with 0–10V Dimming and Daisy-Chain Control

Output dials from 100W to 680W via 0–10V dimming. Daisy-chain control lets a single signal drive three or six fixtures off one controller. Growers typically hang at 18–36 inches above canopy and ramp up the dimmer as the plants stretch. IP65 protection handles hydroponic plumbing humidity, and ETL plus DLC opens the door to utility energy rebates. The fixture ships with a 5-year warranty.

Key Features
