LED Grow Lights

About

LED Grow Lights for Indoor & Outdoor Growing Modern LED grow lights deliver full-spectrum photon output at significantly lower energy consumption and heat production than traditional HID fixtures. The reduced radiant heat lowers HVAC load and operating costs across the growing cycle, while advanced diode arrays provide the broad spectrum coverage that supports strong vegetative growth through dense flowering. LED technology now dominates new commercial CEA builds and is the most common choice for home and hobby growers upgrading from HID systems. LED Grow Light Brands: Growers Choice, Gavita, Faven, Matrix & More Hydrobuilder carries LED grow lights from qualified brands including Growers Choice, Gavita, Faven Lighting, Matrix, Photontek, ThinkGrow, AC Infinity, and Mars Hydro. Fixtures range from compact 100W bar-style LEDs for propagation spaces and small tents up to 2,000W+ commercial bar arrays for large-canopy production rooms. Full-spectrum models cover vegetative and flowering requirements in a single fixture. Dimmable and spectrally adjustable models offer flexibility for multi-crop facilities and research applications. Our updated best LED grow lights guide covers top-performing fixtures across every budget and canopy size. Fixture Types: Panels, Bar Arrays & Bulbs LED panels are the most common format - integrated heat sink, driver, and diode array in a single unit. Bar-style LED arrays distribute light more evenly across wide canopies and can be hung closer to plants due to their lower intensity per bar - the preferred format for top commercial brands including Gavita, Growers Choice, and Faven. Bar arrays reduce intensity hot spots that single-source panels can create, improving canopy uniformity across the full footprint. Under-canopy LED bars can supplement overhead fixtures for bottom canopy penetration - see our updated guide to under-canopy lighting for setup guidance.
