Agrolight LED Sirius: Samsung-powered grow panels in three wattages

Get professional full-spectrum lighting at an accessible price point. The Agrolight Sirius series delivers 2.7 µmol/J efficiency across all three models thanks to latest-generation Samsung diodes and a balanced 3400K spectrum that covers veg and bloom without panel swaps. A built-in five-step dimmer adapts output to every growth stage.

The 240W suits 100×100 cm footprints, the 360W increases photon density for higher yields and the 480W reaches 1296 µmol/s for large-scale setups. IP65 moisture protection, RJ controller port and 50,000+ hour lifespan. Fast delivery across Belgium.

Our Agrolight LED Sirius range

Looking for a grow light that balances affordability with professional performance? The Agrolight LED Sirius series is built for exactly that. Three wattages equipped with latest-generation Samsung diodes, balanced full-spectrum 3400K output and IP65 moisture protection — stocked at Plant & Flower as part of our broader LED lighting selection for Belgian indoor growers.

Dimmable Samsung grow panels for every grow space

Agrolight LED has earned a reputation as an accessible yet powerful option in horticultural lighting. The Sirius series builds on their popular Quantum Board range with important upgrades: Samsung diodes replacing Epistar, IP65 certification for use in humid environments, and an RJ port for external controller integration. The four-bar LED layout distributes light evenly across the canopy without hot spots, while generating less heat than compact panels of comparable output — reducing the load on your grow tent ventilation.

Sirius 240W, 360W or 480W — which one?

The Agrolight Sirius 240W is the entry point, optimised for 100 × 100 cm grow spaces. Its compact form factor and light 4.3 kg weight make it easy to install in most grow tents. The four LED bars deliver uniform light distribution across the entire canopy without the central hot spots common in single-panel designs. At the recommended 30-40 cm hanging distance, the 704 µmol/s PPF supports both vegetative growth and flowering.

The Agrolight Sirius 360W raises the output to 1092 µmol/s PPF while maintaining the same 2.7 µmol/J efficiency — useful for growers who want higher photon density on a similar footprint, such as CO₂-enriched setups where plants can take advantage of more available light. The Agrolight Sirius 480W is the top-tier model with 1464 Samsung diodes and 1296 µmol/s PPF, suited for experienced growers covering tents up to 120 × 120 cm. Start at 60-70 cm hanging distance and lower gradually based on plant response. All three deliver significantly less heat than comparable HPS/MH bulbs, lowering the demand on ventilation and climate control across a full grow cycle — a real operational saving during warm months.

FAQ - Frequently asked questions about Agrolight LED

Which Agrolight Sirius fits my tent size?

The Sirius 240W is optimised for 100 × 100 cm, the 360W suits similar footprints where higher photon density is desired, and the 480W covers up to 120 × 120 cm. For a 60 × 60 cm propagation tent, dim the 240W to 40-60 % rather than choosing a smaller model you'll outgrow.

What is the difference between Agrolight Quantum Board and Sirius?

The Quantum Board range uses Epistar 3030 LEDs at lower efficiency. The Sirius series is equipped with Samsung diodes delivering 2.7 µmol/J, plus IP65 moisture resistance and an RJ port for external controllers. Sirius represents Agrolight's newer, higher-performance product line aimed at growers who want professional specs without premium pricing.

Are Sirius panels dimmable?

Yes. Every Sirius model includes a built-in five-step dimmer (20, 40, 60, 80 and 100 %). For finer control, the RJ port accepts an external controller that adjusts intensity continuously and can automate day/night cycles — useful for precise light management during sensitive growth stages.

How much electricity does a Sirius save compared to HPS?

At 2.7 µmol/J efficiency, a Sirius panel delivers similar usable light to a comparable-wattage HPS while drawing less electricity and producing far less heat. Combined with reduced ventilation load, total energy savings across a full grow cycle can be substantial — especially during warm months when HPS heat output forces extra cooling.
