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 incredible2.4 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.

        Customer Reviews

        Based on 23 reviews

        Absolutely love the Optic8+ . Fast delivery and excellent service ! :)

        Optic 8 plus 120° lenses

        Purchased this light and boy was it ever worth it. Waited to write this review until I had a good amount of time to use the light. Well im impressed with the quality of this light. By far the best light I have used to date. The dimmable aspect of the light really helps dial in the best spectrum for your plants your growing. My plants are healthier,bigger and over all happy girls. I would recommend this light to any grower. Once again thank you to led grow lights Depot for the fast shipping and great product.

        Optic 8+

        This is an amazing light, quality built and zero issues, I would recommend to anyone using in a 4x4 tent. Arrived quickly.

        Beautiful Light

        The sprouts seem to be reacting to the COB LEDs, I can’t wait to see the flowers under the full Optic 8 spectrum.

        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.
