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).
The LEDs in the Optic 8+ fixture are equivalent to a double ended 1200 watt HPS bulb in terms of their output. Included are:
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:
The following table shows the vertical PPFD:
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.
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.
The Optic LED 3500K Optic 8+ is an insanely powerful fixture that delivers the output of a DE 1500 watt HPS light but only uses 700 watts of power. It features both warm white and cool white COBs, plus a proprietary blend of secondary LEDs that deliver a huge boost during blooming for monstrous yields of up to 3.5 pounds.
