Plants Are Unique.
Spectrums Should Be Too.

Daylight Spectral Distribution

PBAR refers to Plant Biologically Active Radiation and designates the spectral range from 280–800 nm. According to the American Society of Agricultural and Biological Engineering (ASABE), PBAR covers a more substantial range of light that affects plant biology. The PBAR measurement includes the PAR band from 400–700 nm as well as the ultraviolet radiation band of 280–400 nm and the infrared radiation band of 700–800 nm. Active Grow reports both the PAR and PBAR values for all product specifications as the 280-800 nm range is becoming more widely recognized and incorporated into industry lighting standards.

CRI <70

Active Grow LED CRI >95

The Color Rendering Index (CRI) measures a light source’s ability to accurately reproduce the colors of objects in comparison to natural sunlight (CRI 100). This 100-point scale examines 15 different R values of a light source and uses the average of R1-R8 to calculate the CRI value. Traditional grow light sources typically have low CRI values and may create uncomfortable working environments. Poor color reproduction also makes it difficult for growers to visually identify issues with plants like pests and fungus.

Traditional HPS Spectrum CRI <25

Active Grow Entourage Spectrum CRI 94

Active Grow offers various high CRI light spectrums specifically designed with both plants and growers in mind. These full-spectrum light formulas create bright, vivid grow spaces and are 100% dedicated to promting healthy plant growth. Choose from Active Grow’s Entourage (CRI 94), Sun White (CRI 95), Autumn Sun (CRI 95), Spring Sun (CRI 95) and Sun White Pro (CRI 88) high CRI spectrums and stop growing in the dark.

Active Grow Spectrum Formulas

Entourage Spectrum

Our trademark spectrum hits on three precise light wavelengths to promote healthy plant growth in any stage. This full-spectrum light goes beyond the traditional PAR range (400-700 nm) with dedicated 730 nm far-red wavelengths that penetrate the canopy, boost healthy growth during vegetative and flowering cycles and increase photosynthesis rates via the Emerson Effect. The natural high CRI 94 light also makes plants look more vivid, helping growers spot pests and fungus like powdery mildew easier.

Sun White Spectrum

The spectrum that started it all and can grow almost anything is a full-spectrum light formulated to mimic natural sunlight conditions and is ideal for every stage of plant growth. High CRI 95 light accentuates plant coloration and makes visual inspection easier. Includes 660 nm (red) and 730 nm (far-red) wavelengths to boost photosynthesis rates via the Emerson Effect.

Sun White Pro Spectrum

Our most professional grade production spectrum and a game changer for commercial facilities is formulated with higher blue light content and dedicated 660 nm (red) wavelengths to promote healthy vegetative growth, root development, tight internodal spacing, phytochemical production and increased flavonoid content.

Spring Sun Spectrum

High CRI 95 full-spectrum light formulated to mimic natural spring sun conditions with additional far-red light that boosts plant photosynthesis rates via the Emerson Effect. Designed for promoting plant compactness, tighter internodal spacing and healthy foliage development.

Bright White Spectrum

When we say bright, we mean BRIGHT. This full-spectrum light is designed to achieve maximum PAR range (400-700 nm) efficacy for high light intensity requirement plants and is especially effective in the vegetative stage.

Blue Sun Spectrum

The coolest spectrum around features 450 nm (blue) wavelengths and full-spectrum 6500K white light. Even at 11,500K CCT, dedicated far-red wavelengths help with light penetration through foliage and even water. This spectrum accentuates colors and promotes healthy development of mushrooms, clones, coral and increases coloration in red lettuce varieties.

Greenhouse Spectrum

Professional grade full-spectrum light formulated to promote healthy full-cycle growth, root development, tight internodal spacing and flower production.

Red Bloom Spectrum

Far-Red wavelengths boost light absorption, speed up plant growth and combine with blue wavelengths to promote root development, budding and fruiting.

Red Bloom Pro Spectrum

Pink light is power, and not a photon is wasted with this chlorophyll-boosting, full-spectrum light that hits precisely on 450 nm (blue) and 660 nm (red) wavelengths. This spectrum also features additional far-red light that increases plant photosynthesis rates via the Emerson Effect. Designed to increase plant mass, speed up plant growth and promote healthy carotenoid development, budding and fruiting.

Red Boost Spectrum

Dedicated heavy red and light blue wavelengths efficiently boost healthy vegetative and flowering stages by speeding up chlorophyll absorption rates to create faster growth cycles.

Green Dream Spectrum

Soft green light with dominant 510-530 nm wavelengths ensures plants remain “asleep” during dark cycles.
