Lumatek LED Zeus 300W PRO 3.1 µmol/J

Product detailed description

Lumatek Zeus 300W PRO 3.1 is a compact linear LED fixture for growers who light smaller or narrow areas - grow tents with low ceilings, single-tier and multi-tier systems. With three interchangeable LED bars fitted with Samsung LM301H EVO and Osram 4.24 diodes, it spreads the full spectrum evenly across an area of 1.2 x 0.6 m, so plants receive the same light from edge to edge.

Which Zeus PRO 3.1 version to choose

Wattage determines the area the fixture can cover - Lumatek Zeus 300W PRO 3.1 is the smallest member of the range and is aimed at an area of 1.2 x 0.6 m. For a larger footprint, do not skimp on power: Zeus 465W PRO 3.1 covers 1.2 x 1.2 m, while the more powerful siblings reach up to 1.5 x 1.5 m. Efficiency of 3.1 µmol/J remains the same across the entire range - only the area and total light output differ, not the light quality.

Diodes, interchangeable LED bars and full control

The panel is fitted with Samsung LM301H EVO and Osram 4.24 diodes with a 120° beam angle, arranged into three magnetic LED bars that you can replace individually - if damaged or upgraded, you do not need to buy the entire fixture. With the included 0-10V dimmer, you can reduce the output in steps of OFF-25-50-75-100 % according to the plant stage without losing efficiency. Through the external control port, you can connect the panel to Lumatek Digital Panel Controller Plus 2.0 or any universal 0-10V controller and control multiple fixtures at once.

Why the investment pays off

The higher purchase price of a quality LED pays back on the electricity bill and in yield. Efficiency of 3.1 µmol/J means more usable light from every watt, passive cooling without a fan saves noise and reduces failure risk, and the IP65 rating withstands the humidity common in a grow room. With a lifespan of over 60,000 hours and a five-year warranty, this is a fixture for years, not for one season.

Frequently asked questions

How large an area is Lumatek Zeus 300W PRO 3.1 suitable for?

Lumatek states coverage of 1.2 x 0.6 m, ideally a narrow tent or a shelf in a multi-tier system. Thanks to the even distribution of light from three LED bars, plants receive the same intensity across the whole area. For a larger footprint, choose a more powerful Zeus model - the area scales with wattage, not with efficiency, which is 3.1 across the whole range.

Which diodes does Zeus 300W PRO 3.1 use?

The fixture is fitted with Samsung LM301H EVO and Osram 4.24 diodes with a 120° beam angle. Together they create a full spectrum for the entire plant cycle, and the wide angle ensures even coverage even at the edges of the area. Quality diodes are reflected in the high efficiency of 3.1 µmol/J.

Can I dim the fixture?

Yes. The package includes a 0-10V dimmer, which lets you set the output in steps of OFF, 25, 50, 75 and 100 %. Dimming does not reduce the fixture's efficiency, so you save electricity during growth and run at full power during bloom. To control multiple units at once, connect an external controller and use timing as well as automatic dimming.

How do I control Zeus 300W PRO 3.1 with a timer?

The photoperiod is most reliably controlled by a Lumatek controller, which switches the fixture on and dims it according to the programme. If you use a standard timer, choose a type that switches the live conductor. For powerful LEDs with an integrated driver, we recommend control via a controller, where inrush current is handled.
