Mammoth Lighting Nova Sun Series Review: Sunlike Spectrum for Bigger Yields

We’re taking a close look at the Nova Sun Series by Mammoth Lighting. This is Mammoth’s most advanced full-spectrum line yet, designed to replicate natural sunlight and help growers maximize yields, terpene content, and overall plant health. With models available in 720W, 820W, and a fully tunable 950W version, there’s a Nova Sun fixture for every grow room, whether you’re a home grower, commercial cultivator, or R&D facility. In this review, I’ll cover the spectrum, model comparisons, and performance specs. 

Unboxing & Setup

Out of the box, the Nova Sun comes with everything you need to get up and running: the LED bars, driver, power cords for 120V and 240V setups, RJ cables (RJ12 or RJ45 depending on model), and hanging hardware. The packaging is discreet with a removable Mammoth label on request, which is a nice touch for stealth growers. The fixtures are modular and field-serviceable, with removable bars and drivers, which simplifies both setup and future maintenance. Dimensions are 44" x 44" x 4", making them a great fit for 4x4 or 5x5 grow areas.

Spectrum & Diodes

This fixture stands out with its custom-engineered Emerald Green + Red Terp Boost Spectrum. It features dual red peaks at 640nm and 660nm for strong flowering performance, a unique teal blue peak at 480nm for enhanced vegetative growth, and far-red at 730nm to trigger the Emerson Enhancement Effect—boosting photosynthesis, stretch, and flowering response. It also includes a balanced mix of cool and warm white diodes for broad-spectrum coverage that mimics sunlight. All models are powered by Ledestar Nova chips and other premium OSRAM/Samsung diodes for top-tier performance.

Why Spectrum Still Matters

Spectrum isn’t just about red and blue anymore. Recent research continues to show that full-spectrum light, like sunlight, drives better results in yield, plant health, morphology, and cannabinoid/terpene expression. The Nova Sun Series is built around this principle.

Studies like McCree (1972), Snowden (2016), and Zhen (2022) have highlighted how balanced spectrums with blue, green, red, and far-red wavelengths lead to more efficient photosynthesis and better plant structure. Green light, long considered useless in photosynthesis, actually penetrates deeper into the canopy (Kim, 2004; Terashima, 2009), driving photosynthesis in lower leaves and boosting overall efficiency.

Performance & PAR Output

All Nova Sun models deliver strong PAR output and excellent uniformity. Expect slightly higher PAR readings in tents or reflective environments. We recommend hanging these lights 12"–24" above canopy, depending on your stage and intensity goals.
