The Optic 8 combines 8 of CREE's largest and most efficient COB LEDs (the XLAMP CXB3590)

With industry leading glass optical projection lenses and 312 CREE and Samsung supplemental diodes.

The COBs are a mix of 3500K daylight white (6x) and 5000K cool white light (2x), making this light perfect for all stages of growth. The supplemental diodes add a powerful boost for blooming that help this light yield up to 3.5 pounds.

In addition to more and better bloom boosting diodes, the Optic 8 has two other major improvements: spectrum control and controller ports, so you can hook up Optic's touch screen master controller (sold separately here, but you save $100 if you add it to your light order above).

Optic 8+ COB LED Grow Light Features

  • Proven Yield: Up to 3.5 lbs in 4x4 and up to 4.68 lbs in 5x5
  • Large Footprint: Covers 5 x 5 max with a 18" canopy penetration or 4 x 4 with a 30" penetration
  • Equivalent to 1500w DE HPS: insane output for only 712w draw
  • 3500K and 5000K CREE COBs: 6 daylight white and 2 cool white COBS for a perfect mix that is great for all stages of growth
  • 312 "Bloom Enhancer" LEDs: a proprietary blend that provides a huge boost during blooming
  • 3 Independent Dimmers: dimmer for veg (2x 5000k and 2x 3500k COBS), for bloom (4x 3500K COBS) and for bloom enhancer (supplementary LEDs), so you can save on electricity by turning down lights you don't need.
  • 10-year warranty: industry best
  • Controller Port: use Optic's 7" Touchscreen Optic LED Master Controller to control light(s) remotely (but not required, you can also use the settings directly on the fixture); add the controller option above to save $100 over buying it separately; note that an external timer is still needed to turn the light on or off

Top Quality LEDs Deliver Extreme Power

The LEDs in the Optic 8+ fixture are equivalent to a double ended 1200 watt HPS bulb in terms of their output. Included are:

  • 8x 3500K and 5000K CREE XLAMP CXB3590 COB 137 watt LEDs driven continuously at 50 watts
  • 256x Samsung LM301H horticulture series LEDs
  • 32x Samsun LH351H V2 Deep Red 660nm LED chips
  • 166x Samsung LH351H Royal Blue 450nm LED chips
  • 4x LG UV LEDs
  • 4x IR LEDs

Both the COBs and the bloom boosting diodes have the power to penetrate deep below the canopy. Secondary lenses focus the light even further and increase the PAR output and canopy penetration by up to 200%. The drivers are the industry-best from Meanwell.

The PPF per watt is 2.5 umol/j. The PPFD at 15 inches is 1200+. The following table shows the PAR footprint over a 4x4 area at 12 inches:

Perfect Full Spectrum Light For All Stages With Spectrum Control

The mix of 3500K and 5000K COBs provides a white light that is great for all stages of growth. The supplemental LEDs provide a huge boost of red, blue, white, UV and IR that makes for monstrous yields of up to 3+ pounds per light.

The 2 Switches and 3 Dimmers Save On Electricity Costs When You Don't Need Full Power

You have a COB on/off switch and a separate bloom boost switch, so you can leave the supplementary LEDs off during veg to save power.

Furthermore, you have a dimmer for the bloom enhancer LEDs, another one for veg and another for flowering. The veg dimmer controls the two 5000K COBs and two of the 3500K ones. The flower dimmer controls the remaining four 3500K COBS.

Loving my Optic 8+

Seeing a great improvement over the Kind Led I had before

John Y
Best value out there!

You won't find a better deal than this at the moment. If this light was made by one of the big names, it would cost twice as much.
