iLuminar iLogic8 UV + Far-Red Output and Build
This version shares its frame and draw with the full-spectrum iLogic8 but adds UV-A and far-red diodes to the mix. Retail listings rate it at 1,700 µmol/s and 2.7 µmol/J. That is the same figure given for the full-spectrum model, so check iLuminar's ePAR rating if the far-red share matters for your math. Input is smart-sensing from 100V to 277V. The power cord is sold separately. The frame measures 41.9 x 39.4 x 4.9 in and weighs about 50.3 lb, with four hanging points. Extruded aluminum fins cool it without fans. Light spreads at 120° from bars that release with clips for service. The housing is IP66 rated for damp and wet rooms. It carries ETL, DLC, FCC and CE listings, with 50,000+ hour diodes and a 5-year warranty.
What a Far Red Grow Light Changes in Flower
A far red grow light adds photons just past the visible red band, which work together with red light to lift photosynthesis. iLuminar reports less stretch during transition, more branching and higher terpene and essential oil output from the added UV-A and far red. The footprint is 4 x 4 ft with the fixture 8 to 12 inches above the canopy. Start dimmed on 0–10V in veg and raise intensity through the first weeks of flower. UV-A can stress sensitive cultivars, so watch new growth for curling or bronzing during the first run. Dimming works with iLuminar's Touch+ controller, its dimmer switch or a standard room controller. LED puts less heat on leaves than HPS, so many growers raise the room a few degrees after switching. Plants often drink less under LED, so water by pot weight. Wipe the inset diodes between runs to keep output steady. If you do not want UV in the room, the full-spectrum iLogic8 is the better choice.
