A win win for greenhouse and indoor growers

Seamless integration, reduced energy costs, increased productivity, and improved crop quality all stack up to absorb capital expenditure in just a few crop cycles. Growers also benefit from the vastly improved spectral quality as well as ILUMINAR Lighting's commitment to unparalleled customer service and support.

Controllable, Reliable, and Compatible

The iLogic™121 works with the majority of 0-10V lighting controllers on the market (including ILUMINAR Lighting's Touch+ Controller) allowing cultivators to enjoy 10 to 100% dimming functionality as well as complete control over photoperiod including sunrise and sunset settings.


Built to excel even in the toughest cultivation environments, the iLogic™121 is IP65 rated for protection against dust ingress and water projected from foliar sprayers.



Grow Beyond PAR

The iLogic™121 delivers a carefully balanced, plant-usable spectrum deep into the canopy. Both spectrums have been designed to support full lifecycle plant development and maximum productivity in high and super-high Daily Light Integral (DLI) plant species.


Consuming just 780 watts, the iLogic™121 easily outperforms similar “HPS replacement” LED fixtures on the market with superior output, spectral quality, and efficiency. The addition of UV and Far-Red promotes stronger, healthier plants with more flower sites and increased production of essential oils.

  • Wattage: 780W

  • Longer Lifespan: 50,000 hours

  • 22% reduction in energy consumption

The World’s Most Advanced HPS Replacement LED

Designed for straightforward and easy installation within existing HPS lighting plans, the iLogic™121 represents so much more than a simple 1-to-1 HPS replacement for greenhouse and indoor growers.


While it perfectly matches the footprint and hanging height of legacy 1000W DE-HPS grow lights, the iLogic™121 offers a range of exciting new benefits for cultivators.

  • Wattage: 780W

  • PPF: 2100 µmol/s 

  • Efficacy: 2.7µmol/J

  • Dimming: 0-10V

  • Longer Lifespan: 50,000 hours

  • 32% reduction in energy consumption

Benefits of
Growing with UV

  • Promote stronger, healthier seedlings / cuttings during propagation and early vegetative growth

  • Help to counteract the stretching effect of red and far-red

  • Create a more inhospitable environment for pests, molds, and other pathogens

  • More closely replicate the native spectral diet of higher altitude plant species

  • Take crop quality to the next level by stimulating increased production of secondary metabolites including flavonoids, stilbenes, and other quality-enhancing compounds

  • Enhance photosynthetic efficiency when supplied in conjunction with PAR

Benefits of
Growing with Far-Red

  • Quicken the transition from vegetative development to generative production

  • Boost production of secondary metabolites including terpenes and essential oils

  • Promote increased flower size and density

  • Enhance photosynthetic efficiency when supplied in conjunction with PAR
