Lumatek Zeus 465W LED Grow Light – High Efficiency Lighting for Smaller Spaces
The Lumatek Zeus 465W LED Grow Light delivers outstanding performance in compact grow spaces. Available in two models – the Pro 3.1 and Pro 2.9 – this LED bar fixture gives you powerful, full-spectrum light with industry-leading efficiency, without the heat buildup or energy waste you’d expect from older tech.
Both variants are built using a multi-bar layout that spreads light evenly across the canopy. This makes the Zeus 465W ideal for tents around 1.2m x 1.2m, where uniform PPFD is critical to getting the most out of every inch. The Pro 3.1 uses updated diodes to push efficiency even further, delivering up to 3.1 µmol/J while maintaining excellent spectrum balance for all growth stages. The Pro 2.9, meanwhile, offers proven results and exceptional consistency – a great choice if you want maximum value without sacrificing quality.
As with other Lumatek fixtures, the Zeus 465W is completely passively cooled using aluminium heat sinks, so there are no noisy fans or moving parts to wear out. The entire unit is IP65 rated, making it safe to use in humid conditions, and the onboard dimmer gives you instant control over light intensity. For more advanced setups, both models can be linked to the Lumatek controller for precise, programmable control of multiple units.
Whether you're upgrading from a lower-efficiency system or setting up a new small-to-medium grow room, the Zeus 465W range provides everything you need to grow healthy plants with total confidence – with less heat, less energy use, and more usable light where it matters most.
Technical Specs
| Model | Efficiency | PPF | Power Draw | Spectrum | Recommended Area |
|---|---|---|---|---|---|
| Zeus 465W Pro 3.1 | 3.1 µmol/J | 1450 µmol/s | 465W | Full Spectrum | Up to 1.2m x 1.2m |
| Zeus 465W Pro 2.9 | 2.9 µmol/J | 1353 µmol/s | 465W | Full Spectrum | Up to 1.2m x 1.2m |
Both models deliver consistent performance across every stage of plant development, with solid build quality and efficiency figures that make them ideal for growers who want better results without high energy bills or temperature spikes. Backed by Lumatek’s five-year warranty, these are fixtures built to perform crop after crop.

How To Use
How to Use the Lumatek Zeus Pro
Lumatek Zeus grow lights can be assembled in around five minutes. All you need to do is put together the frame, screw the driver (power supply) in place, fit the LED light strips, and connect up the controller.
The Lumatek Zeus Pro 465w is great for a 1m square area but could be used in a 1.2m area. Lumatek recommend a light height of around 500mm (perhaps a little lower for the 465w version). However, this is only a general guide. When plants first go under an LED grow light they can take a while to adjust to it. When the plants first go under it, we would recommend a slightly higher distance from the light to the top of the canopy, or turning down the power. Over the course of several days the light height can be reduced slowly and/or power can be increased gradually. After the plants have developed it may be possible to reduce the light height to below 500mm. Keep an eye out for any signs of stress (droopy or discoloured leaves) and increase the light height if necessary.
Lumatek have done a really good job with the instruction manual, and it makes the process incredibly clear.
