Optic LED Optic 4 Gen4 370w Dimmable LED Grow Light
Optic LED’s new Optic 4 Gen4 grow light is packed with more power and growth potential than ever before. This fixture offers the unmatched combination of yield and potency thanks to all top-of-the line high quality components for a superior product that you won't find anywhere else on the market today. You can also control how much light your plants receive by dimming COBs or bloom enhancers, giving you even more options when it comes to intensity as well as energy consumption!
Optic LED's spectrum ranges from 460nm to 660nm, covering the entire PAR spectrum + UV-A and near-infrared (far red). The additional green light helps increase photosynthesis deep in the leaves and inside the canopy. Far-red light, when combined with red light, has been proven to increase the rate of photosynthesis.
The Optic 4 Gen4 is more efficient than ever, using less power to deliver even more light and significantly higher yields of up to 888 grams / 31.71 oz / 1.98 lbs. The LEDs in the fixture are equivalent to a 650 watt HPS bulb on paper but will still outperform it by far with its COBs and supplemental diodes that have enough oomph to penetrate deep below the canopy while secondary lenses focus any remaining energy for an increased PAR output of up 200%.
The COBs and the Samsung diodes deliver a full-spectrum white light that is great for all stages of growth. The CREE supplemental LEDs add red and blue to give plants even more of the wavelengths they need the most. They also add UV and IR wavelengths.
You can run the Optic 4 at full power or you can run either only the COB lights or only the supplemental LEDs. Being able to turn off some of the lights lets you save on power costs when you don't need the full output.
