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 32 Osram 3 watt LEDs for the most penetrating light ever.

The COBs are a mix of 3500K warm white light (6x) and 5000K cool white light (2x), making this light perfect for all stages of growth. The Osram diodes add a powerful boost for blooming that help this light yield up to 2.5 pounds.

There is a second version available with 120° lenses instead of the regular 90° lenses, which spread out the light a bit more and give you a larger coverage area (5 by 5 versus 4 by 4). You can select that version above, directly below the price.

 

Optic 8+ COB LED Grow Light Features

  • Equivalent to 1000w DE HPS: insane output for only 500w draw
  • 3500K and 5000K CREE COBs: 6 warm white and 2 cool white COBS for a perfect mix that is great for all stages of growth
  • 3 Watt "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 (Osram 3w LEDs), so you can save on electricity by turning down lights you don't need.
  • 10-year warranty: you'll see other stores call it a lifetime warranty, but read the fine print...it's 10 years

 

Top Quality LEDs Deliver Extreme Power

The LEDs in the Optic 8+ fixture are equivalent to a double ended 1000 watt HPS bulb in terms of their output. Included are:

  • 3500K and 5000K CREE XLAMP CXB3590 COB 132 watt LEDs driven continuously at 50 watts
  • 3 watt Osram ultra efficient LEDs with glass projection lenses

Both the COBs and the 3 watt 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.

 

Output and Coverage with 90° Lenses

The PAR in the center of the foot print at an 18-inch hanging height is 1828 umol/m2/s. The PPFD is 861.46.

PAR Footprint at 18 Inches (4 by 4 Coverage Area):

Optic 8 90 Lens PAR Footprint at 18 Inches

 

At 24 inches, the PAR is 1420 u/mols at the center of the footprint and the PPFD is 780.5.

PAR Footprint at 24 Inches (4 by 4 Coverage Area):

90 degree PAR Footprint at 24 Inches

 

The recommended hanging height with the 90° lenses is 18 to 24 inches for flowering and 24 to 36 inches for vegging. With these lenses, the Optic 8 covers a 4 by 4 area for bloom and a 6 by 6 area for veg.

 

Output and Coverage with 120° Lenses

The PAR in the center of the foot print at an 18-inch hanging height is 1973 umol/m2/s. The PPFD is 833.70.

PAR Footprint at 18 Inches (4 by 4 Coverage Area):

120 Degree PPFD Footprint 18 Inches

 

At 24 inches, the PAR is 1285 u/mols at the center of the footprint and the PPFD is 678.46.

PAR Footprint at 24 Inches (4 by 4 Coverage Area):

120 Degree PPFD Footprint 24 Inches

 

With the 120° lenses, the possible coverage area increases to 5 x 5 for bloom. The recommended hanging height are is 18 to 24 inches for flowering a 55 area (16" to 20" for a 4x4 area) and 24 to 30 inches for vegging.

 

Perfect Full Spectrum Light For All Stages Plus Huge Boost For Flowering

The mix of 3500K and 5000K COBs provides a white light that is great for all stages of growth. The supplemental 3 watt Osram LEDs provide a huge boost of red that makes for monstrous yields of up to 2.5 pounds per light.

 

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

You have an on/off switch and a separate bloom boost switch, so you can leave the Osram 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.

dimming knobs

The owners manual details recommended settings for the various stages of plant growth. Here are some example spectra you can create using the dimming knobs.
