Full Spectrum Grow Lights

Full spectrum grow LED fixtures mimic the sun’s natural wavelengths, providing plants with blue, green, red, and even far-red light. This broad range promotes strong root development, balanced vegetative growth, and heavy flowering without needing bulb swaps.

Research shows that the spectrum shapes plant morphology, but intensity drives yield. A full spectrum plant light delivers both, ideal for home grows and commercial setups needing simplicity and performance in one fixture. 

Get access to our unbeatable grow light deals with energy incentives and commercial discounts. Plus, find clone, veg, flowering, and full cycle grow lights fast with our grow light comparison table.

Frequently Asked Questions

How do I know if a grow light is truly full‑spectrum?

Look for a continuous spectral distribution that mimics sunlight, with a high Color Rendering Index (CRI ≈ 95–100) and complete coverage across blue, green, red, and even some UV/IR wavelengths; packaging and CRI/CCT specs, independent certifications, and real-world “white light” appearance are good indicators.

What color should a full spectrum grow light appear?

A full spectrum LED grow light for indoor plants emits white light, not purple or blue-red “blurple”. It appears as natural daylight (CCT ≈ 5000–6500 K) because it includes balanced blue, green, and red wavelengths.

How far should a full‑spectrum LED light be from my plants?

Placement depends on intensity: seedlings often need lights 8–12 inches above, while mature plants are typically hung 2–4 feet away to ensure optimal PPFD without light burn.

Which light spectrum is best for plant growth?

The ideal spectrum of full spectrum grow lights for seedlings to veg spans the full PAR range (400–700 nm), with balanced red and blue plus some green—and optionally far-red/UV—to support both yield and plant health; intensity (PPFD/DLI) is still the most important factor. Learn more about PPFD/DLI in our latest blog.

Are energy rebates available for commercial and large indoor setups?

Yes! Many utility and government programs offer rebates that can cover 50–100% of the cost of qualifying LED grow lights (and even HVAC/dehumidifier upgrades), saving commercial growers thousands and relieving grid strain. Check your eligibility here!
