A Full-Spectrum CMH-Style LED Grow Light Engineered for Maximum Genetic Expression

“We didn’t just replicate CMH — we evolved it.”

For more than four decades, cultivators have searched for the ideal indoor grow light: one capable of reproducing the intensity, spectral balance, and biological harmony of natural sunlight while delivering the efficiency and control of modern LED technology.

That search may finally be over.

The 2026 Nova Sun Series from Mammoth Lighting represents a new generation of full-spectrum LED grow lights inspired by the broad-spectrum performance of Ceramic Metal Halide (CMH) lighting and engineered with advanced spectral tuning, high-CRI output, and precision LED efficiency.

Designed and patented in Upstate New York, the Nova Sun Series was built for serious cultivators, breeders, and commercial facilities seeking deeper canopy penetration, improved terpene expression, stronger morphology, and true full-spectrum performance.

Why Full Spectrum Matters More Than Ever

Plants evolved under the complete spectral arc of the sun — not under narrow spikes of red and blue light.

Yet for years, much of the LED industry prioritized PPE numbers over plant physiology, focusing heavily on narrowband red and blue spectrums that optimized efficiency metrics while often compromising overall plant development.

The consequences became increasingly apparent in high-performance cultivation environments:

• Reduced terpene and secondary metabolite development
• Photoinhibition under extreme PPFD levels
• Weak morphology and excessive stretching
• Poor hormonal signaling and unbalanced photoreceptor activation
• Reduced canopy development in dense flowering canopies

Modern plant science increasingly supports what experienced cultivators have observed for years:

broader spectrums produce more natural, balanced, and complete plant expression.

The Research Behind Full-Spectrum Cultivation Lighting

Numerous peer-reviewed studies now demonstrate the importance of broad-spectrum lighting in controlled environment agriculture.

Key Research Findings

Hogewoning et al. (2010)

Broad-spectrum lighting enhances photosynthetic response and produces more normal plant morphology compared to narrow red/blue lighting systems.

Zhen & Bugbee (2020)

Green light and far-red radiation play critical roles in canopy penetration, photoreceptor signaling, and whole-plant photosynthetic efficiency.

Johkan et al. (2012)

Excessively narrow red/blue spectrums may disrupt hormonal balance and negatively affect structural development.

Park & Runkle (2018)

Narrowband LED lighting was associated with reduced biomass accumulation compared to broad-spectrum systems.

Kim et al. (2004)

Red-heavy lighting can negatively influence flowering quality and overall plant architecture.

Bottom Line

Cannabis was never designed to evolve under isolated red and blue spikes. Full-spectrum lighting more closely aligns with the biological conditions under which plants naturally developed.

CMH Changed Cultivation Lighting — Nova Sun Evolves It

For years, CMH (Ceramic Metal Halide) fixtures were considered the gold standard for premium indoor flower production due to their broad-spectrum output, UV inclusion, and superior crop morphology compared to traditional HPS systems and early-generation LEDs.

Cultivators consistently reported:

• richer terpene profiles
• tighter internodal spacing
• stronger branching
• improved flower quality
• more natural plant expression

But CMH had clear limitations:

• excessive heat output
• lower electrical efficiency
• bulb degradation over time
• limited spectral control
• high HVAC demand

The Nova Sun Series was engineered to preserve the biological advantages of CMH while eliminating the inefficiencies associated with legacy discharge lighting.

Simulate the Natural Arc of the Sun

Advanced Spectrum Tuning Technology

Unlike static-spectrum fixtures, the Nova Sun Series offers advanced multi-channel tuning designed to simulate natural daylight progression from sunrise to sunset.

Cultivators can create up to five daily spectrum stages, including:

Dawn

Cool white dominant spectrum for early vegetative signaling

Morning

Balanced full-spectrum output for vigorous growth and leaf expansion

Midday

High-intensity warm white flowering spectrum for maximal photosynthetic output

Afternoon

Enhanced red and far-red balancing for flowering response and canopy development

Dusk

Far-red enriched spectrum designed to support Emerson Effect signaling and photoperiod transition

This dynamic spectral capability allows growers to better optimize:

• Daily Light Integral (DLI)
• photomorphogenic signaling
• flowering triggers
• canopy response
• environmental simulation

The result is a more natural indoor lighting environment capable of supporting full genetic expression throughout the entire plant lifecycle.

What Makes the Nova Sun Spectrum Different?

The Nova Sun Series was designed to activate every major plant photoreceptor using a broad, balanced spectral strategy rather than chasing narrow efficiency metrics alone.
