The Lumatek ATS300W PRO is a compact, fanless LED grow light built for 1x1m spaces. It puts out 816 µmol/s PPF at 2.7 µmol/J efficacy — verified, not marketing guesswork — using top-bin white, red, and far-red diodes across a full spectrum tuned for every stage of growth. Passive cooling, zero noise, fully dimmable, IP65-rated, and RCM certified for Australian growers. This is the light you put in a 1x1m tent when you want to do it properly.

What's in the Box
- Start at 50-75% output during the first week of flower and ramp up progressively — the fixture is rated for 1x1m at full power, but your plants need time to acclimate.
- Hang at 30-45 cm above the canopy during flowering for optimal PPFD distribution. Raise it during early veg or seedling stages rather than dimming further.
- The included 0-10V dimmer is plug-and-play for single-light setups. If you're running a controller, connect it to the external control port and the dimmer steps away automatically.
- IP65 means this fixture handles humid grow room conditions — just don't spray it directly. Wipe it down between grows to keep the Clear Glue-protected bars clean and transmitting at full efficiency.
- No fans means no fan noise and no fan failure. But passive cooling still needs ambient airflow across the fixture — don't mount it flush against a ceiling with zero clearance above.
Diode Technology
Earlier LED designs focused on royal blue and deep red wavelengths to target chlorophyll absorption peaks. They worked, but they left gaps — poor canopy penetration, missing spectra for full plant development, and terrible visibility in the grow room. The ATS300W PRO uses a calibrated blend of white, deep red, and far-red top-bin diodes that covers the full spectrum plants actually use. The result is higher intensity with uniform distribution, stronger canopy penetration without hotspots, and a grow space you can actually see in. The Clear Glue protection cover on the LED bars adds 99% light transmittance, extended diode lifetime, and corrosion resistance — all without compromising output. Diode temperatures stay low by design, which directly extends the L90 lifespan and keeps lumen maintenance high across the full 60,000-hour rated life.
Control Systems
The ATS300W PRO ships with a 0-10V dimmer for immediate standalone use — no controller required out of the box. For growers who want automation, it connects directly to the Lumatek Digital Panel Plus 2.0, giving you light timing, automated dimming in 1% increments, temperature safety features, and Sunrise/Sunset modes across up to 100 fixtures from a single controller. Running a different brand controller? As long as it outputs a 0-10V signal, this fixture is compatible. If your controller uses an RJ port, a signal converter adapts it to 0-10V without replacing your existing gear. The ATS PRO fits cleanly into whatever control ecosystem you are already running.

Frequently Asked Questions
What size grow space is the ATS300W PRO designed for?
The ATS300W PRO is rated for a 1x1m footprint at full power. It will cover that space with even, uniform light and good canopy penetration. It is not the right choice for a 1.2x1.2m or larger tent at full power — for that footprint, look at the Lumatek Zeus 600W PRO or a fixture in the 465-600W range.
Does the ATS300W PRO need a separate controller?
No — it ships with a 0-10V manual dimmer that covers four power steps: 25%, 50%, 75%, and 100%. That is enough to run the fixture through a full grow cycle without a controller. If you want automated scheduling, 1% dimming resolution, or multi-fixture control, you will need a compatible Lumatek controller or universal 0-10V controller, sold separately.
Will it work with my AC Infinity or third-party controller?
Yes — the ATS300W PRO is compatible with any controller that outputs a standard 0-10V signal. If your controller uses an RJ port interface instead of a direct 0-10V connection, you will need a signal converter (RJ to 0-10V adapter) to bridge the two. Check your controller's spec sheet to confirm the output signal type before purchasing the adapter.
Is the passive cooling actually effective — does it run hot?
Yes — the passive heat sink design handles thermals effectively at 310W input. The fixture will feel warm to touch during operation, which is normal. It does not run hot enough to cause problems under typical grow room conditions. The one thing to avoid is mounting it with no airflow clearance above — passive convection needs some air movement across the heat sink to work as designed. Normal grow tent ventilation is more than sufficient.
What does IP65 actually mean for a grow light?
IP65 means the fixture is fully dust-tight and protected against water jets from any direction. In a grow room context, it means humid conditions, condensation, and the occasional water splash will not damage the electronics or the LED bars. It does not mean it is submersible — do not run it in a fully wet environment. For most indoor growers, IP65 is more than adequate for long-term reliability in a typical grow tent.
What is L90 and why does it matter?
L90 is a verified measurement of light maintenance — it means the fixture retains at least 90% of its original PPF output after 60,000 hours of operation. Most grow light brands quote L70 (70% output) as their lifespan figure, which sounds impressive until you realise your light is running 30% dimmer and you might not have noticed. The ATS300W PRO's L90 rating at 60,000 hours is an independently verified figure, not a calculated estimate — it means you are getting consistent output for the full life of the fixture.
Is it RCM certified for Australian use?
Yes — the ATS300W PRO carries RCM certification along with CE, EMC, LVD, TISI, and L90. RCM (Regulatory Compliance Mark) is the Australian and New Zealand standard for electrical safety and electromagnetic compatibility. Buying a certified fixture means it has been tested to a recognised standard and is legal to operate on Australian mains power.
