Mammoth Nova Sun Grow Light with Tunable Spectrum Review

Introducing the Mammoth Nova Sun Grow Light

• 💡 The Mammoth Nova Sun series is a new grow light designed to replicate sunlight and ceramic metal halide spectrums, offering the fullest spectrum tested by the reviewer.
• 🚀 This 950-watt, 8-bar model incorporates a wide range of LEDs in configurations not typically seen in grow lights, delivering a high-output package.
• ✅ The fixture features easy assembly, with bars that clip and screw into place, allowing for simple replacement if damaged.

Advanced Spectrum Technology

• 🌈 The light utilizes four separate channels: UVA/UVB bars, far red bars, a warm white channel with 660nm red, and a cool channel blending warm white, green, light blue, dark blue, and reds.
• 🔬 The reviewer used Mammoth's new spectra radiometer and power meter (priced at $449) to test the spectrum output, praising its impressiveness and value compared to more expensive alternatives.
• ⚡ When all bars are on, the combined output creates a broad spectrum that closely mimics the sun's spectrum and ceramic metal halide lights.

Performance and Efficiency Testing

• 📊 The light was tested in a 5x5 grow area at an 18-inch hanging height, consuming 952 watts (excluding UVA/UVB).
• 📈 In the 5x5 setup, it delivered an average PPFD of 994 with a system efficiency of 2.35 usable PPF per watt.
• 🔥 When tested in a 4x4 grow area at the same height and wattage, it achieved an average PPFD of 1521, indicating pro-level power numbers, with an efficiency of 2.3 usable PPF per watt.

Pricing and Value

• 💰 The 950W fixture with variable spectrum (cool white, warm white, far red) is priced at $999.
• 🏷️ An additional set of 100W UVA and UVB bars (two bars) can be added for $299.
• 🌟 The reviewer considers both the grow light and the spectra radiometer to offer excellent value for money given their performance and features.
