The Helios 520 EVO+ isn’t just a light—it’s a photosynthetic powerhouse, engineered in New Zealand and tearing it up in commercial grow facilities nationwide.
This beast pumps out 520w watts of photon-fueled fury, leveraging Samsung LM301H EVO diodes with a photosynthetic photon efficacy (PPE) of 3.14 µmol/J along with Samsung LM301h diodes (PPE) of 3.1 µmol/J and 4Season 2835 Diodes (PPE) of 2.8 µmol/J —converting raw energy into usable light that slams your plants with a full-spectrum barrage of 3000K and 5000K white light for vigorous vegetative growth, spiked with OSRAM’s 660nm deep red and 730nm far-red to trigger photomorphogenic responses—think denser Flowers and larger fruit production that’ll make your competition weep.
Spanning a 120cm x 120cm flowering footprint (150cm x 150cm for veg), the 520EVO+ out performs the likes of traditional 600w bulb lighting in every aspect, lighting coverage, power usage, plant growth and significantly lower heat, slashing heat output via a chunky aluminum heatsink with a thermal conductivity of 237 W/m·K. That means silent, passive cooling—no whiny fans, just pure, uninterrupted growth.
Dial in the intensity with 0-100% dimming control, delivering precise PPFD levels from seedling to harvest— Across NZ, the 4Seasons EVO+ LED Grow Lights are already the commercial growers go to LED grow light solution.
Built for serious growers seeking serious results, measuring 80cm x 80cm - the Helios 520 EVO+ is NZ Safety certified, rocking a 50,000+ hour lifespan (that’s 5.7 years at 24/7), and comes with a 5-year Herbal House warranty. Sync it with the 4Seasons Master Controller or AC INFINITY controller (via TypeA adapter) for more automation, and you’re running a lab-grade operation.
At NZ’s average commercial power rate of 21.34 cents per kWh, this Grow Light costs just $1.23 per day to run for 12 hours—cheaper than a flat white. Free shipping, discreet packaging—your grow, your rules.
We ensure that all of our products undergo rigorous quality testing and extensive packaging to reduce the chance of any defects, however, in the unlikely circumstance that there is a failure with your purchased goods, simply take a deep breath and get in touch.

Great light! Got as a free upgrade because the light i ordered was out of stock, Matt’s a legend as always! Cheers team!
This is the 3rd HELIOS 480K led grow light I have purchased from Herbal house, I find them to be an excellent grow light, the quality is second to none, and very reliable, because the lights intensity is fully adjustable I use them on my plants from start to finish. I highly recommed them.
Here's a item that has bounced in and out of my cart in contemplation , from first impressions unboxing, to first plugged n these are amazing lights . The build quality and appearance are top notch, can't wait to see some end results
Was a little hesitant in buying this light, only as it’s a fairly large spend. Am I glad I did. It’s a perfect fit for my situation and the light is so easy to hang. From there it’s easy to raise and lower the light. I’m more than happy with my purchase and herbal house gives super fast service and delivery is so fast and right to the door. Thanks guys, I will be back.

PPFD Chart Breakdown (520W Full-Spectrum LED Grow Light)
The Helios 520 EVO+ is designed for serious growers needing strong, even canopy coverage. This PPFD chart shows peak readings of 1151 µmol/m²/s in the center, ideal for flowering. Surrounding zones stay strong at 1080–1100 µmol/m²/s, ensuring high-intensity performance across the core footprint.
Even at the outer edges, PPFD levels stay solid: 614–675 µmol/m²/s 636–773 µmol/m²/s
This means less light drop-off and better yields across your entire tent or tray. The uniformity here beats most panels in its class.
With an average PPFD around 900–950 µmol/m²/s, this 520W panel punches above its weight—offering performance close to 600W HPS with better efficiency. It’s powered by Samsung LM301H EVO diodes and OSRAM reds, passively cooled, and fully dimmable to suit all growth stages.
High-Density Diode Configuration for Maximum Efficiency
The Helios 520 EVO+ features 2,064 diodes, delivering powerful full-spectrum light with next-level efficiency. Each diode runs at just 0.25W when the panel is at full 520W power, reducing energy waste and heat output.
🔹 Lower wattage per diode = higher efficacy More usable light per watt, meaning stronger growth with lower power costs.
🔹 Improved longevity & reliability Running cool extends diode life and reduces failure rates—perfect for long-term NZ grows.
🔹 Even canopy coverage With 2,000+ diodes spaced for balance, expect smooth PPFD across your entire grow space—no hot spots, no shadow patches.
Advanced PCB Layout for Perfect Light Spread – 520 EVO+
he Helios 520 EVO+ uses a precision-engineered diode layout designed for ultra-uniform light distribution. Instead of packing all the intensity in the center, diodes are strategically spaced to balance output across your entire canopy.
🔹 No central hotspots Even light intensity—no burning plants directly under the fixture.
🔹 Stronger edge coverage Better PPFD at the edges for a fuller, more productive grow.
🔹 Deeper canopy penetration More consistent growth from top to bottom, improving yields and plant health.
This smart PCB design sets the Helios 520 EVO+ apart from traditional LED grow lights, giving New Zealand growers professional results in tents, rooms, or commercial setups.
Full-Spectrum Output for Every Growth Stage – 520 EVO+
The Helios 520 EVO+ delivers a finely tuned full-spectrum light profile designed for full-cycle plant growth—seed to harvest.
🔹 Blue (~450nm / 5000K) – Promotes tight, vigorous vegetative growth with strong stems and healthy foliage. 🔹 Green-Yellow (~500–600nm) – Improves light penetration through dense canopies for even growth. 🔹 Deep Red (~660nm) – Boosts photosynthesis and enhances flowering, increasing yield and bud density. 🔹 Infrared (~730nm) – Triggers phytochrome shifts to speed up flowering and push final yield through the Emerson Effect.
With this balanced blend of wavelengths, the Helios 520 EVO+ ensures faster growth, denser plant structure, and bigger harvests—all while staying energy-efficient.
