Aelius 300 Bar LED Grow Light - XRF or REDD Spectrums

Choose the XRF Spectrum if you want a single fixture capable of supporting your crop from seedling through veg and into flower — it's the more flexible, all-purpose option. Choose the REDD Spectrum if your primary goal is maximizing flowering and fruiting output, or if you're using the fixture for greenhouse light supplementation where a blue and red-dominant profile performs best.

The Aelius 300 covers a 3×4 ft canopy footprint at full power. Its slim 4" × 40" bar form factor makes it easy to position precisely over smaller canopies, supplemental greenhouse rows, or tight spaces where a wider panel fixture wouldn't fit effectively.

Yes. The Aelius 300 supports a wide voltage range of 100–480V, covering both standard low voltage (100–277V) and high voltage (200–480V) inputs. A 120V adapter is included in the box for use on standard North American outlets, and a 240V power cord is also included for direct high-voltage connections.

The Aelius 300 uses 0-10V RJ-14 daisy-chain dimming. Connect a dimmer or controller to the first fixture's RJ-14 port, then run a daisy-chain cable from that fixture to the next, repeating until all lights are linked. Refer to your controller's specifications for the maximum number of fixtures supported per channel.

The current Aelius 300 is the 4th generation of the fixture that originally launched Aelius LED. The 4th gen brings refined spectrum tuning across both options, along with efficacy exceeding 3.0 µmol/J — a significant improvement over earlier generations while retaining the same slim, lightweight bar form factor seen in the Aelius Matrx 320 Lite.

Use low-pressure compressed air or a gentle water rinse to remove dust and debris from the LED modules and heat sinks. Never pressure wash the fixture. Always power down and allow the unit to cool completely before handling or cleaning, and avoid touching individual LEDs with bare fingers to prevent electrostatic discharge damage.
