Select Lens Angle

Optic LED has now seamlessly integrated eight of CREE's largest most efficient COBs (XLAMP CXB-3590) with industry-leading glass optical projection lenses to give you unprecedented light penetration with the highest PPFD of any 500-watt lighting system.

The combination of these two technologies combined with a proprietary blend of 3-watt Osram LEDs will give you significantly improved grams per watt yield and significant increases in trichome density and quality.

Growing with the Optic 8+ you can expect to yield up to 2.5 pounds which is an incredible 2.4 grams per watt.

This fixture is ideal for vegging a 6' x 6' area or flowering a 4' x 4' to 5' x 5' area.


The Optic 8+ spectrum ranges from 380nm to 780nm, 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.

Spectrum on OPTIC 8+ @ Full Power - All 3 Dimmers @100%

Spectrum for VEG - VEG Dimmer @100% & Bloom Dimmer @10% - only the COBS on. VEG Dimmer controls the two 5000k COBs which gives you more blue light and two 3500k COBs.

Spectrum of COBS only @ Full Power - Veg Dimmer @100%, Bloom Dimmer @100% & Bloom Enhancers Off. (Used in VEG & Flower)
