Quick Answer

430W full spectrum LED delivering 1058 µmol/s PPF at 2.52 µmol/J efficacy for a 1.2m x 1.2m footprint.
Passive cold forged aluminium cooling, no fans, no failure points, rated for 60,000+ hours.
MeanWell HLG driver with 0 to 100% dimming, the same standard serious commercial operators specify.
Australian made and certified, 5 year full warranty with local support.

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.

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 the Medic SS420+ LED cover?

The Medic SS420+ covers up to 1.4m x 1.4m in veg and 1.2m x 1.2m at full flowering intensity. Coverage depends on your target PPFD and hanging height, refer to the PAR map in the specifications for precise readings at your setup height.

How far should I hang the Medic SS420+ from my canopy?

During propagation and early veg, hang higher to reduce intensity. Most growers target 40 to 60cm above canopy during flowering. Always use a PAR meter or the manufacturer's PPFD chart to dial in the exact distance for your setup.

Does the Medic SS420+ run hot? Do I need extra cooling?

The Medic SS420+ uses passive cooling via a cold forged aluminium heat sink, no fans required. You will still need adequate tent ventilation for temperature and humidity control, but this light does not require water cooling or additional heat management beyond standard grow room airflow.

What is the warranty on the Medic SS420+ in Australia?

The Medic SS420+ comes with a 5-year full warranty with Australian-backed support through Apex Grow. Contact hello@apexgrow.com.au with your order number and we will arrange a replacement or repair.

Can I dim the Medic SS420+ for seedlings and clones?

Yes, the Medic SS420+ includes 0-100% dimming control. Start at 20 to 30% output for seedlings and clones and increase progressively as plants mature and can handle higher light levels.
