4Seasons HELIOS 1000 EVO+ LED Grow Light

Tested in a 1.5m x 1.5m grow space at a 45cm hanging height, the 4Seasons HELIOS 1000 EVO+ delivers intense, uniform lighting specifically tuned for flowering plants. Running at a true 1000W, this commercial-grade fixture is engineered to maximise both energy efficiency and yield potential.

With an average PPFD of 1606 µmol/m²/s, the HELIOS 1000 EVO+ ensures your entire canopy receives consistent, high-intensity light—driving strong, uniform growth from edge to edge. At the centre, peak PPFD readings reach an impressive 1910 µmol/m²/s, pushing dense bud formation and optimal flowering development.

Even at the outer edges of your grow space, PPFD levels stay above 1200 µmol/m²/s, maintaining strong light intensity without the need for supplemental lighting—giving you true edge-to-edge coverage.

Rated at 1.61 µmol/J efficiency (based on average PPFD divided by actual 1000W power draw), the HELIOS 1000 EVO+ proves it’s not just powerful, but also highly energy-efficient—making it a top-tier choice for both commercial growers and serious home growers looking to maximise yields while controlling running costs.

The Helios 1000X is engineered with a finely tuned full-spectrum output, delivering targeted wavelengths that optimise plant growth at every stage—from seedling through to harvest. Its strategic spectral peaks ensure your plants get exactly what they need for faster, healthier development and bigger yields.

Blue light (~450nm / 5000K) drives strong chlorophyll absorption, encouraging compact, sturdy vegetative growth with thick stems and vibrant foliage. To support deeper canopy development, the fixture emits green-yellow light (500–600nm), enhancing light penetration through dense growth and ensuring consistent development across all plant levels.

During flowering, the red spectrum (~660nm) kicks in to accelerate photosynthesis, boosting bud production and improving both yield size and quality. Complementing this is the infrared (~730nm) output, which triggers phytochrome conversion—speeding up flowering cycles and enhancing final yield potential through the Emerson Effect.

With this carefully balanced blend of blue, green-yellow, deep red, and far-red wavelengths, the Helios 1000X delivers faster growth, denser foliage, and higher crop yields—making it a top-tier choice for full-cycle cultivation.

The 4Season HELIOS 1000 EVO+ LED Grow Light is engineered with a hybrid diode array that blends top-tier performance with cost-efficiency—perfect for serious Australian growers chasing maximum yields without unnecessary overhead.

At its core, the panel integrates Samsung LM301H EVO and LM301H diodes, delivering up to 3.14 μmol/J for powerful, energy-efficient vegetative growth and flowering performance. Complementing this are 4Seasons 2835 diodes, trusted by Australia and New Zealand’s leading commercial growers for their reliability and balanced light spectrum.

To drive flowering performance even further, Osram 660nm deep red and 730nm far-red diodes are incorporated, achieving up to 3.8 μmol/J efficacy. This powerful red/far-red combination enhances photosynthesis, accelerates flowering, and pushes yields higher.

By strategically blending these high-performance diodes, the 1000 EVO+ produces a powerful, full-spectrum output with deep canopy penetration and optimised light distribution—delivering commercial-grade results at exceptional value.

The 4Season HELIOS 1000 EVO+ is designed with an algorithmically optimised diode layout, purpose-built for maximum light uniformity across large grow spaces. Unlike conventional LED panels that concentrate diodes in the centre, the 1000 EVO+ features a strategic arrangement—densely clustering diodes at both ends while spacing them more widely through the centre.

This smart design significantly reduces central hotspots, preventing excessive light intensity directly beneath the fixture. At the same time, it enhances edge illumination, delivering stronger, more consistent PPFD levels across your entire grow area—right to the edges.

By distributing light more evenly, the HELIOS 1000 EVO+ ensures deeper canopy penetration, supporting healthier, more uniform plant development from top to bottom. This precision layout gives growers the consistency needed for higher yields and better-quality harvests, whether in commercial facilities or serious home setups.

The 4Season HELIOS 1000 EVO+ is built with an impressive 3,226 diodes, delivering serious light intensity while maintaining exceptional efficiency. Each diode operates at just 0.31W when running at full 1000W output, significantly lower than their maximum capacity—a design choice that offers multiple performance advantages.

By running each diode at reduced wattage, the HELIOS 1000 EVO+ achieves higher photon efficacy, converting more electrical power into usable light, with less wasted as heat. This not only improves energy efficiency but also extends the lifespan and stability of the diodes by minimising thermal stress, ensuring reliable performance over tens of thousands of hours.

With such a high diode count, the panel distributes light more evenly across its entire surface, creating a smooth, uniform PPFD footprint. This eliminates hotspots and ensures your entire canopy receives consistent, balanced light—essential for even plant growth and maximised yield.

By using a vast array of low-powered, high-efficiency diodes, the HELIOS 1000 EVO+ maximises light output while maintaining optimal efficiency, making it one of the most advanced and reliable LED grow lights available for Australian growers today
