The Optic 4 Gen3 features upgraded COBs with 33% higher efficacy, plus 20% larger heat sinks so the light runs cooler and lasts longer. It combines 4 CREE COB LEDs with 64 Bridgelux/Epistar 5 watt LEDs, giving you the best of both worlds. And it does so at an unheard of price for a top-quality LED light.

 

Which Optic 4 is best for you?

  • 3000K (Bloom Version): Has warm white COBs with a color temperature of 3000K. This makes it a flowering monster with yields of up to up to 1.30 pounds per light.
  • 3000K + 5000K (Full Cycle Version): Has a mix of warm white COBs with a color temperature of 3000K and cool white COBs with a temperature of 5000K making it the perfect full-cycle light.

    If you need more than one, select one of the bundled options above and save big.

     

    Optic 4 Gen3 COB Grow Light Features

    • Equivalent to 600w HPS: insane output for only 405w draw
    • Choice of Color Temp: warm white 3000K CREE COB light that is great for all stages, but especially flowering or mix of 3000K and 5000K COBS, which add cool light that is perfect for vegging, making the mixed version the ideal full-cycle light
    • 5 Watt Supplemental LEDs: red, blue and white to give plants more of the light they crave
    • 3 Modes: run at full power, COBs only, or 5 watt LEDs only to save power when you don't need full output
    • 5 year warranty: buy risk free

     

    Top Quality LEDs Deliver Extreme Power

    The LEDs in the Optic 4 fixture are equivalent to a 600 watt HPS bulb in terms of their output. Included are:

    • 3000K and/or 5000K CREE 80 watt XLAMP CXB2540 COBs driven continuously at 55 watts
    • 5 watt Epistar dual core red diodes
    • 5 watt Bridgelux dual core blue diodes
    • 5 watt Bridgelux single core white diodes

    Both the COBs and the 5 watt diodes have the power to penetrate deep below the canopy. Secondary lenses focus the light even further and increase the PAR output by up to 200%.

    The PPFD at 24 inches is 823.83. The following table shows the PAR footprint over a 3x3 area at 24 inches.

    The PPFD at 20 inches is 845.13. The following table shows the PAR footprint at 20 inches.

    The recommended hanging height during flowering is 24 inches. During vegging, it is 24 to 36 inches. For seedlings, hang the light at 36 inches.

    This gives you a 3.3 by 3.3 coverage area during flowering and a 4 by 4 area during vegging. 

     

    Perfect Full Spectrum Light

    The COBs deliver a full-spectrum white light that is great for all stages of growth and their light also contains UV and IR wavelengths. 

    The supplemental 5 watt LEDs add red, blue and white light to give plants even more of the wavelengths they need the most.

     

    3000K Version

    The 3000K COBs provide a warm white light that is perfect for flowering (you can use it for all stages, but the mixed version below is much better for vegging) due to more red and orange light.

    5000K Version

    Swapping two of the 3000K COBs for 5000K COBs adds some cool white light that contains more blue wavelengths and is great for vegging.

    3 Modes Save On Electricity Costs When You Don't Need Full Power

    You can run the Optic 4 at full power or you can run either only the COB lights or only the 5 watt 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.
