Medic SS420 LED

This 430W Full Spectrum LED was engineered to delivering commercial-grade output with the efficiency and reliability Australian growers need.

Why This Light Performs

Full Botanical Spectrum. Optimised PAR Output

Covers the full PAR range from veg through to late flower. Not a generic white LED, a purpose-built spectrum that drives photosynthesis at every stage, resulting in stronger structure and better yield quality.

2.52 µmol/J Efficacy. More Light, Less Power

Every watt counts. At 2.52 µmol/J, this unit converts electricity into usable plant energy more efficiently than most commercial fixtures on the market. Lower running costs, no performance compromise.

1058 µmol/s PPF. Growth-Driving Intensity

PPF is what actually drives growth speed, flower density, and final yield. 1058 µmol/s puts this light in the same bracket as fixtures costing significantly more.

Deep Canopy Penetration

Most lights saturate the top canopy and drop off fast. This one reaches lower bud sites consistently, and the difference shows up at harvest in denser, more uniform flowers across the whole plant.

Cold Forged Aluminium Heat Sink. Passive Cooling

No fans, no noise, no failure points. The cold forged aluminium dissipates heat passively, keeping the unit running cool and stable across its 60,000+ hour lifespan.

MeanWell HLG Driver

The industry standard for a reason. Stable power delivery, proven long-term reliability, and full 0-100% dimming control. This is the driver serious operators specify by name.

430W LED vs 600W HPS

Coverage

• Veg: Up to 1.4m x 1.4m | Hang height: 60-90cm
• Flower: Up to 1.2m x 1.2m | Hang height: 45-60cm

Is a 430W LED enough for a 1.2m x 1.2m tent?

Yes. At 1058 µmol/s and 2.52 µmol/J, this unit hits commercial-grade PPFD levels across a 1.2m x 1.2m flowering footprint, without the heat load of a 600W HPS.

Why does Australian made matter for grow lighting?

Local manufacture means 240V compliance, components rated for Australian conditions, and warranty support that doesn't involve shipping a unit overseas. It's built here, tested here, and backed here.

IP66 Rated

Dust-tight and jet-water resistant (without dimmer).
Built for the humidity, condensation, and variable conditions of real grow environments, not just a clean lab.

58% Less Heat vs Traditional Lighting

Less heat in the room means less work for your extraction and HVAC. That saving compounds across every run.

Australian Made & Certified

Manufactured in Australia. Compliant with Australian electrical standards. Backed by a 5-year full warranty with local support. No grey market, no import risk.

Frequently Asked Questions

What growing area does Medic SS420+ LED Grow Light cover?

Medic SS420+ LED Grow Light is engineered for professional indoor cultivation. Coverage area depends on whether you are in the vegetative or flowering stage — LED lights typically cover a slightly smaller footprint at full flowering intensity than during veg. Refer to the coverage chart included with the light or in the product specifications for precise PPFD maps at your target hanging height.

How far should I hang Medic SS420+ LED Grow Light from my canopy?

Recommended hanging height varies by growth stage. During propagation and early vegetative growth, hang higher to reduce intensity. Move the light progressively closer as plants develop. Most growers target 40–60cm above canopy during flowering. Always use a PAR meter or manufacturer's PPFD chart to dial in the exact distance for your setup.

Does Medic SS420+ LED Grow Light run hot? Do I need extra cooling?

Medic SS420+ LED Grow Light is a full-spectrum LED designed for high efficiency with minimal heat output compared to equivalent HPS fixtures. Passive or active thermal management is built into the unit. You will still need adequate tent ventilation for temperature and humidity control, but Medic SS420+ LED Grow Light does not require water cooling or additional heat management beyond standard grow room airflow.

What is the warranty on Medic SS420+ LED Grow Light in Australia?

Medic SS420+ LED Grow Light comes with a manufacturer warranty covering defects in materials and workmanship. Warranty claims are handled through Apex Grow. Contact us at hello@apexgrow.com.au with your order number and a description of the issue and we will arrange a replacement or repair.

Can I dim Medic SS420+ LED Grow Light for seedlings and clones?

Yes — Medic SS420+ LED Grow Light includes a dimming function allowing you to reduce output for young plants, seedlings, and clones that cannot handle full intensity. Start at 20–30% output and increase progressively as plants mature and can tolerate higher light levels.
