The First True CMH/MH + HPS Checkered Board Spectrum in LED
A grow light engineered to replicate the natural balance of sunlight, finally closing the gaps in blue and green most LEDs miss. With enhanced spectrum tuning (on select models), the Nova Sun unlocks deeper plant expression, heavier yields, and stronger terpenes.This isn’t just another grow light. Engineered in Upstate New York. 🇺🇸

Don’t settle for outdated red/blue LEDs — follow nature’s lead with Mammoth.
Finally
A Greenhouse Light That Truly Mimics Nature
Most greenhouse lights rely on outdated, red-heavy designs focused on 660 nm efficacy. Plants don’t respond to marketing metrics — they respond to a balanced, natural spectrum.
Introducing our latest innovation: the Air Sanitizer, featuring cutting-edge HEPA, PCO, and Plasma technologies. Engineered specifically for grow rooms, it effectively reduces bacteria and eliminates mold, ensuring cleaner, healthier air for your plants. Maintain optimal growing conditions, meet strict testing standards, and protect your crops with our state-of-the-art air purification system—designed to maximize your grow room’s performance and crop quality.
While many companies recycle old designs or white-label fixtures from China, Mammoth does the hard work — with real patents and original engineering.
We’re honored to be objectively selected as one of the best lights of 2025 by LEDGrowLightsDepot, a retailer and reviewer of hundreds of grow lights.

At Mammoth Lighting, we understand the significance of third-party objective data. Our lighting designs are rooted in academic research and validated through our own extensive trial data. Explore the latest findings in research below.
1. Choose the Right Fixture
Single-bar lights are designed for high-bay and greenhouse installs. Used indoors and too close to the canopy, they create hotspots and uneven coverage.
Multibar fixtures deliver better uniformity, higher PPF, and can be mounted closer to plants for stronger, more consistent yields.
2. Use Spectrum Tuning Wisely
Spectrum tuning works best when all key wavelengths remain present (blue, green, red, far-red). Extreme red/blue shifts or removing colors can reduce usable light and plant performance.
The popular “end-of-day far-red” concept has largely been debunked (e.g., Dr. Bruce Bugbee) and others.
"This may be especially evident given that dry inflorescence yield increased linearly with increasing canopy-level PPFD up to 1800 μmol·m-2·s-1, while leaf-level photosynthesis saturated well below 1800 μmol·m-2·s-1.
"The density of the apical inflorescence and harvest index also increased linearly with increasing LI, resulting in higher-quality marketable tissues and less superfluous tissue to dispose of. Even under ambient C02"
"Our results provide evidence that hemp growers could substantially increase profits by using light intensity levels that are much higher than is the convention today.
The positive, apparently linear relationship between intensity and yields continues to at least 1500 µmols/m2· s, which is over twice the level provided by an HPS fixture in a grow configuration, which is currently the industry standard.
It took less time for the LED treatments to reach peak ripeness, and the resulting morphology of plants grown under high-intensity LEDs is more desirable from a profitability perspective."
"White light with a dual red peak at 640 and 660 nm, compared to white light with a single red peak at 660 nm, increased inflorescence yield and light use efficiency, regardless of PPFD....at higher PPFD, white light with a dual red peak of 640 and 660nm compared to white light with a single red peak at 660 nm increased terpenoidconcentrations."

The Nova Sun Spectrum closely replicates natural sunlight, delivering balanced red, blue, green, and far-red wavelengths for deeper canopy penetration, stronger growth, and fuller plant expression.
Inspired by the proven performance of MH + HPS rooms, Nova Sun blends flowering-driven reds with structure-building blues and greens—while adding full-spectrum tuning to simulate sunrise, midday, and sunset.
The result: healthier plants, richer terpene profiles, and higher-quality yields—powered by science and perfected for serious cultivators.
