Complete RX-G80 Series Wattage Options Explained
The RX-G80 series by Koray Lighting is one of the most versatile foldable commercial grow light lines on the market, offering six distinct wattage configurations to match every stage of cultivation and every scale of operation. Whether you are running a small medicinal plant tent or a full-scale commercial vertical farm, understanding the wattage options within the G80 family is the first step toward maximizing yield per kilowatt-hour.
Koray Lighting, established in 2009 in Zhongshan, Guangdong, has spent over 17 years refining secondary optical systems for horticultural lighting. The RX-G80 series represents the culmination of that expertise, combining Koray’s proprietary optical design with high-efficiency LM301H EVO LEDs across a wattage range from 500W to 1500W. Every model in the series shares the same 1160x1088x70mm form factor, meaning you can upgrade wattage without changing your growing infrastructure.
The Six RX-G80 Wattage Models
The RX-G80 series is available in the following wattage configurations, each designed for a specific coverage and intensity requirement:
RX-G80-500W — The entry point for the series. At 500 watts, this model delivers strong PPFD output suitable for single-layer tent growing of leafy greens and seedlings. It draws approximately 5.0 amps at 120V, making it compatible with standard household circuits. Ideal coverage: 1.0×1.0m for vegetables, 0.8×0.8m for flowering.
RX-G80-650W — The most popular mid-range option. The 650W model strikes an excellent balance between power draw and light output. It delivers PPFD levels comparable to competing 800W fixtures while consuming significantly less electricity. Koray’s field data shows this model saves growers up to 876 kWh per year compared to traditional 1000W HPS systems. Ideal coverage: 1.2×1.2m for vegetables, 1.0×1.0m for flowering.
RX-G80-700W (Dual-Channel) — A specialized model featuring dual-channel adjustable spectrum. Growers can independently control vegetative and flowering LED channels, allowing precise spectrum tuning throughout the crop cycle. This model is particularly popular in medicinal plant cultivation where spectrum recipes vary by growth stage. Ideal coverage: 1.2×1.2m for vegetables, 1.0×1.0m for flowering.
RX-G80-800W — The flagship model and benchmark for the entire series. At 800 watts with the G24B low-green-light full spectrum, the G80-800W delivers a PPF of 2160 μmol/s and PPFD of 1500 μmol/m²/s at 0.2m (measured in a dark room without reflection on a 1.2×1.2m target, 64-point average). This model directly outperforms the Lumatek Zeus 1000W fixture while drawing 200 fewer watts. Ideal coverage: 1.2×1.2m for vegetables, 1.0×1.0m for flowering.
RX-G80-1000W — Designed for large-scale commercial operations requiring maximum photon density. This model is suitable for 1.3×1.3m to 1.5×1.5m flowering coverage and is commonly used in multi-tier vertical farms where top-light intensity is critical. It requires a dedicated 20A circuit at 120V or can be wired to 240V for reduced amp draw.
RX-G80-1500W — The maximum power configuration for industrial-scale cultivation. At 1500 watts, this model is typically deployed in greenhouse supplemental lighting or single-pass flowering rooms where every square meter must receive peak PPFD. It requires 240V wiring and a 20A breaker.
Why Wattage Is Not the Whole Story
Many growers make the mistake of comparing grow lights solely by wattage. The RX-G80 series perfectly illustrates why this approach is misleading. The G80-650W, for example, delivers equivalent or better PPFD than competitor 800W fixtures because of Koray’s secondary optical system. This proprietary lens design eliminates the center hotspot that plagues conventional quantum boards, distributing photons evenly across the entire canopy. The result is that every watt produces usable photosynthetic light at the plant level, rather than being wasted as heat or concentrated in a small zone.
The G24B spectrum used across most G80 models is specifically engineered for low green-light output, which maximizes photosynthetic efficiency. Green light (500-600nm) is largely reflected by chlorophyll, meaning high green-light output wastes energy. The G24B spectrum concentrates photons in the blue (400-500nm) and red (600-700nm) ranges where photosynthesis peaks, while still including enough full-spectrum content for visual plant inspection and worker comfort.
Dimming and Control Across All Wattages
Every RX-G80 model supports three dimming methods: PWM (pulse-width modulation), RX resistance dimming, and standard 0-10V analog dimming. This means growers can precisely tune light intensity regardless of which wattage they choose. All models are also compatible with the HortiGuru APP for wireless group control, enabling automated dimming schedules that mimic natural daylight curves.
The ability to dim is particularly important for the higher-wattage models. A 1500W fixture running at 70% power (1050W) during early flowering delivers the same light level as a 1000W fixture at full power, but with the flexibility to ramp up as plants mature. This approach extends the useful life of the LEDs and reduces electricity costs during growth stages that don’t require maximum intensity.
Choosing the Right G80 Wattage for Your Operation
For home growers with a single 1.2×1.2m tent, the G80-650W or G80-800W provides more than enough intensity for any crop from seedling to harvest. The 650W is the more energy-efficient choice for leafy greens, while the 800W is recommended for fruiting crops like tomatoes and peppers.
For commercial shelf growers running multi-tier racks, the G80-800W or G80-1000W is typically specified. The foldable design allows easy installation between shelf layers, and the lack of center hotspot means lights can be mounted as close as 8 inches (20cm) from the canopy without risk of light burn.
For greenhouse operators supplementing natural sunlight, the G80-1000W or G80-1500W provides the intensity needed to maintain DLI (daily light integral) targets during winter months. The IP65-rated board can withstand humid greenhouse environments, and the 50,000-hour lifespan ensures years of reliable operation.
Shared Features Across the Entire RX-G80 Series
Regardless of which wattage you choose, every RX-G80 model includes the same core features: Koray secondary optical system for hotspot-free uniformity, LM301H EVO LEDs with 50,000-hour rated lifespan, ETL/CE/RoHS/FCC certifications for global market compliance, foldable design for easy installation and shipping, and a 3-year manufacturer warranty. The series also shares the same 1160x1088mm board dimensions, meaning all models fit standard 4x4ft grow tent frames and commercial rack systems without modification.
The RX-G80 series represents Koray Lighting’s commitment to giving growers precise control over their lighting investment. By offering six wattage options within a single form factor, the series allows you to start with the right light for your current operation and scale up as your needs grow, all without changing your infrastructure.
