Aelius 120W Under Canopy LED Grow Light - XR or REDD Spectrum | 2 Pack

Choose the REDD Spectrum if you want targeted blue and red-dominant output under the canopy, similar to the spectrum profile of the Aelius 300 Bar LED, to push flowering performance from top to bottom of the plant. Choose the XR Spectrum if your room is already running REDD or HPS top lighting — XR provides complementary wavelengths that balance your overall light environment and promote more uniform growth across the full canopy rather than adding more of the same spectrum.

The DeepLock™ Quad-Lock System consolidates both power delivery and dimming control into a single connection point on the fixture. This eliminates the need for separate power and data cabling between units, making installation faster and reducing cable management requirements when running multiple fixtures across a row.

Each fixture covers a 12" × 48" strip individually. When both fixtures in the box are positioned at 12" spacing, the combined footprint is 48" × 48" — wide enough to cover a full 4×4 ft canopy row. The 150° wide beam angle ensures even distribution across the full coverage area with no hotspots.

The included aluminum stands elevate the fixture up to 13.02" off the ground. This allows you to position the fixture at the ideal height between canopy rows without any additional mounting hardware or rigging, making repositioning between grows quick and straightforward.

Connect a controller or dimmer to the first fixture's RJ-12 port. Run the included dimming cable from that fixture to the next and repeat until all units are linked. Place the included end cap on the final fixture's open RJ-12 port to seal the chain. Refer to your controller's specifications for the maximum number of fixtures supported per dimming channel.

The 120W Under Canopy is specifically engineered for supplemental under-canopy use rather than primary top lighting. At 360 µmol/s per fixture, it's optimized to supplement existing top lights and reach light-starved lower and side bud sites — not to serve as a primary top light like the Matrx 650F.

Routinely remove dust and debris from the LED modules and heat sink using low-pressure compressed air or a gentle water rinse. Never pressure wash the fixture. Always power down and allow the unit to fully cool before performing any maintenance, and avoid touching individual LEDs with bare fingers to prevent electrostatic discharge damage.
