Essential Info on the Optic 4 Gen 3 COB LED Grow Light

The new Optic 4 Generation 3 COB LED Grow Light features four of the CREE XLAMP CXB2540 warm white COBs (3000 kelvin) which are now 50% more powerful. We have also upgraded our thermal management system with 20% bigger heat sinks so the light runs cooler and lasts longer. The flowering specific spectrum is based on the McCree Action Spectrum which has proven to be the best spectrum for plant photosynthesis. We have loaded our bloom enhancers with FAR RED 640nm & 660nm which will give large resinous flowers. If you are looking for a LED to use exclusively for flowering than the Optic 4 Gen3 "Best for Bloom" is the way to go.
