600 Watt LED Grow Lights for Indoor Growing
A 600W LED grow light hits the sweet spot for mid-size canopy coverage — enough power for productive 4×4 to 5×5 ft flowering footprints, without the electrical demand and heat output of 1,000W fixtures. The 600–700W range is the most popular wattage tier among experienced home growers and small commercial operations that want high photon output with manageable energy and HVAC costs.
600W LED Fixtures: Gavita, Growers Choice, AC Infinity & More
Hydrobuilder carries 600W LED grow lights from qualified brands including Gavita, Growers Choice, AC Infinity, Matrix, and Faven Lighting. The Gavita Pro 1900e — a 650W bar-style fixture — is one of the most widely adopted commercial LEDs at this wattage, delivering uniform high-PPFD output across a 4×5 ft flower footprint with Gavita Master Controller compatibility for facility-wide scheduling and dimming. AC Infinity bar-style LEDs provide excellent performance with integrated dimming and scheduling controls at a compelling price point. All qualified 600W LED fixtures at Hydrobuilder include dimming capability for stage-appropriate light intensity management.
Coverage, PPFD & Plant Count
A 600–700W LED fixture covers a vegetative footprint of approximately 5×5 to 6×6 ft and a flowering footprint of approximately 4×4 to 5×5 ft at standard 18–24 inch hanging heights. PPFD at the center of a 5×5 canopy typically runs 800–1,400 µmol/m²/s — appropriate for most high-light flowering crops. Plant count under a single fixture depends on training style and container size: 1–2 large plants trained to fill the footprint, or 4–9 smaller plants in a sea-of-green configuration. Use our PPFD & Light Coverage Calculator to model your specific canopy layout.
Operating Costs
A 600W LED on an 18-hour vegetative schedule uses approximately 10.8 kWh per day. On a 12-hour flowering schedule, approximately 7.2 kWh per day. At a typical electricity rate of $0.13/kWh, monthly flowering costs run approximately $28–$35. Use our Electricity Cost Calculator for precise cost modeling based on your local rate.
