Optic LED has now seamlessly integrated eight of CREE's largest most efficient COBs (XLAMP CXB-3590) withindustry-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 to2.5 pounds which is an incredible2.25 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.

        Quality Light

        The optic 8 is a beast, I got 2 in my 4x8 tent & my plants love it. It doesn’t create much heat in the tent, it’s very quite, & the bloom enhancers are the perfect touch. You really can’t go wrong with this light, especially considering the lifetime warranty it now comes with.

        So far good

        Light came properly packaged and undamaged. Results so far are exceeding expectations.

        Not for seedlings.

        I'm giving it 3 stars because of the awful misprint or advertising was a bit off saying that this is a full cycle light from seedling to harvest is so incorrect. Had 10+ seedlings under this light and all 10 died. Not from my hand as I have 2 lights side by side comparing them and the other light has this one beat so far.

        Great light, shipping was a bit long

        The light is fantastic, the service was excellent, the only thing is that I thought I was buying a product that was already in North America, but found out it was being shipped from China and had to pay duty after clicking the purchase button - otherwise, great transaction, and I’m very pleased with the light

        Great light

        Didn't had a chance properly go full run but had a chance finish 2 autoflowering plants. From outdoor under the light for last 3 weeks of flower and I'm very happy with the results. Can't wait to do full run with this light. Light is very good build. Over all very good quality.And very good packaging. Just one thing I was surprised there was no manual. But email the company and they sent it to me by email.
        Let say very happy costumer.
